Have you ever stopped to consider what’s floating around in the air inside your home? During the winter months in Mechanicsburg, PA, when the temperatures drop and we keep our windows tightly closed, indoor air can actually become more polluted than the air outside. While it may seem counterintuitive, cold weather encourages families to stay indoors with less ventilation, creating the perfect environment for allergens, dust, and other pollutants to accumulate. That’s why indoor air quality testing is so important. Understanding what’s in your air can help protect your family’s health and make your home more comfortable during the colder months.

Why Indoor Air Quality Matters in Winter

Winter in Mechanicsburg can bring harsh winds, freezing temperatures, and heavy snowfall, which often means your home’s windows and doors remain shut for extended periods. While this keeps the cold out, it also limits airflow, allowing pollutants to build up. Common indoor pollutants include:

• Dust mites and dust

• Pet dander

• Mold spores

• Volatile organic compounds (VOCs) from household cleaners or paints

• Carbon monoxide and other gases from heating appliances

Poor indoor air quality can lead to a range of health issues, from minor irritations like coughing and itchy eyes to more serious problems such as respiratory infections and asthma flare-ups. According to the Environmental Protection Agency (EPA), indoor air can be 2 to 5 times more polluted than outdoor air, and in some cases, the levels can be up to 100 times higher. That makes testing your air quality more than just a precaution—it’s an essential step for protecting your loved ones.

Common Winter Indoor Air Pollutants

Dust and Allergens

During the winter, dust tends to accumulate faster because homes are closed up. Heating systems can circulate dust and allergens throughout your home, triggering sneezing, congestion, and other allergic reactions. Regular cleaning can help, but testing your indoor air will show you exactly how much of these particles are present and whether additional filtration is needed.

Mold and Mildew

Mold growth is more common in areas with poor ventilation and high humidity, such as bathrooms, kitchens, and basements. While winter air may seem dry, indoor humidity can rise due to cooking, showers, and even indoor plants. Mold spores can cause allergic reactions and respiratory issues, making early detection through air quality testing crucial.

Carbon Monoxide and Gas Leaks

Heating systems that rely on gas or oil can sometimes produce carbon monoxide (CO) if not properly maintained. CO is colorless, odorless, and potentially lethal. Indoor air quality testing can detect unsafe levels of CO and other gases before they become a danger.

Volatile Organic Compounds (VOCs)

VOCs are chemicals released from products like paints, cleaning agents, and even furniture. In winter, with doors and windows closed, these compounds can concentrate in your home and affect your health, leading to headaches, dizziness, or irritation of the eyes, nose, and throat.

Benefits of Indoor Air Quality Testing

Testing your indoor air is not just about identifying problems—it’s about prevention and peace of mind. Here are some key benefits for homeowners in Mechanicsburg:

In Mechanicsburg, PA, the weather can feel like a balancing act between warmth and humidity. Even late in the summer, temperatures can hover in the mid-to-high 80s, with sticky air making it feel even hotter. This climate puts a lot of pressure on air conditioning systems, which are tasked with maintaining indoor comfort while fighting against relentless heat and moisture.

Your AC isn’t just pushing out cold air—it’s working against the laws of thermodynamics, battling high outdoor temperatures to move heat from inside your home to the outside. The hotter it is outdoors, the harder this job becomes. Over time, these conditions can impact your unit’s efficiency, cooling capacity, and even its lifespan.

This blog will break down exactly how outdoor temperatures affect AC performance during late summer in Mechanicsburg, what you can do to help your system run more efficiently, and when it’s time to call in a professional like Jeffrey A. Wilbur Plumbing, Heating & Air Inc.

Why Late Summer is a Challenge for AC Systems in Mechanicsburg

Prolonged Heat Waves Take a Toll

Late summer often brings a stretch of consecutive hot days. According to data from the National Weather Service, Mechanicsburg sees an average of 15–20 days above 85°F each summer, and many of these occur after July. When outdoor air is that warm, your AC has to run longer to maintain your preferred indoor temperature, increasing wear on components like the compressor and condenser fan motor.

Humidity Compounds the Problem

Central Pennsylvania summers are known for humidity levels often exceeding 70%. High humidity makes air feel warmer, prompting your AC to run even more. But cooling humid air isn’t just about lowering the temperature—it requires your system to remove excess moisture, which consumes additional energy. In extreme humidity, your system may struggle to keep both the temperature and moisture levels in check.

How Outdoor Temperatures Directly Impact AC Efficiency

The Heat Transfer Process Gets Slower

Your air conditioner works by transferring heat from your indoor air to the outside environment. The greater the difference between indoor and outdoor temperatures, the easier it is for this heat transfer to happen. In late summer, when the air outside is nearly as hot as the refrigerant in your condenser coils, the process becomes less efficient.

A study from the U.S. Department of Energy found that AC efficiency can drop by up to 20% when outdoor temperatures climb above 95°F. That means your system has to work harder to produce the same cooling effect, leading to higher energy bills and more strain on equipment.

Compressor Strain and Overheating

The compressor is essentially the “heart” of your AC system. When outdoor heat is intense, the compressor must maintain higher pressures in the refrigerant lines to move heat effectively. This added workload can cause overheating, leading to system shutdowns or long-term damage if not addressed promptly.

Reduced Cooling Capacity

Even a well-maintained AC unit may deliver less cooling power in high outdoor temperatures. For example, a unit rated to cool a home by 20 degrees might only manage a 15-degree drop during extreme heat. If it’s 92°F outside, your indoor temperature might hover around 77°F despite the thermostat being set lower.

The Role of Humidity in Late Summer AC Performance

Why Humidity Is More Than Just a Comfort Issue

Humidity affects how we perceive temperature. A day that’s 85°F with 75% humidity feels significantly hotter than the same temperature with 40% humidity. This “feels-like” temperature can push your AC to run almost continuously, making it work beyond its intended duty cycle.

Moisture Removal Uses Energy

When your AC removes humidity, it’s performing two tasks: cooling air and condensing moisture. The latent heat removal process uses a portion of the system’s cooling capacity, meaning less energy is left for temperature reduction. This is why a home may still feel warm and sticky even if the AC is running nonstop.

Common AC Issues in Late Summer Due to Outdoor Heat

1. Longer Cooling Cycles

Your AC may run for extended periods without cycling off. While this maintains comfort, it increases wear on parts and energy consumption.

2. Frozen Evaporator Coils

If airflow is restricted (due to dirty filters or blocked vents) while your system is working hard in hot weather, coils can freeze. This can halt cooling entirely until the issue is resolved.

3. Refrigerant Pressure Problems

High outdoor temperatures raise refrigerant pressures, potentially causing safety switches to trip or system shutdowns.

4. Capacitor Failures

Capacitors help motors start and run efficiently. The added heat and workload in late summer can cause these electrical components to fail prematurely.

Ways to Help Your AC Perform Better in Late Summer

Keep Air Filters Clean

Dirty air filters restrict airflow, forcing your AC to work harder and run longer. During peak summer, check filters monthly and replace as needed.

Maintain Proper Thermostat Settings

Avoid setting your thermostat drastically lower than the outdoor temperature. Aim for a comfortable but realistic range—usually around 75–78°F when you’re home.

Use Ceiling Fans

Fans help circulate air, making your home feel cooler without overworking your AC. A fan’s wind-chill effect can make a room feel 3–4°F cooler.

Seal Air Leaks

Prevent warm outdoor air from sneaking into your home by sealing gaps around windows, doors, and ductwork.

Schedule Routine Maintenance

A professional inspection ensures your system’s refrigerant charge, coil cleanliness, and electrical components are in optimal condition—especially important before the hottest days hit.

Why Professional Maintenance Matters More in Late Summer

Late summer is when your AC has already been working hard for months. Without proper care, minor issues can turn into costly breakdowns.

A professional technician can:

• Check refrigerant levels for efficiency and cooling performance

• Inspect and clean condenser and evaporator coils

• Test electrical components for signs of wear

• Ensure the condensate drain is clear to prevent water damage

• Optimize airflow through ductwork

Statistics from the Indoor Air Quality Association show that well-maintained systems can operate 15–20% more efficiently than neglected units. This can make a noticeable difference in both comfort and utility bills during the hottest weeks of the year.

The Energy Cost of Ignoring AC Performance Issues

When your AC runs inefficiently due to high outdoor temperatures, you’ll likely see the impact on your energy bill. The U.S. Energy Information Administration reports that cooling accounts for 12% of total household energy use on average—but in hot, humid climates like central Pennsylvania’s summer, this percentage can rise significantly.

Ignoring performance issues not only increases monthly costs but can shorten your system’s lifespan, leading to premature replacement expenses.

Signs It’s Time to Call a Professional in Late Summer

• Your AC runs nonstop but can’t reach the set temperature

• Unusual noises or vibrations from the outdoor unit

• Weak airflow despite the system running

• Higher-than-normal energy bills without a change in thermostat habits

• Water pooling around the indoor unit from clogged condensate lines

If you notice any of these symptoms, prompt service can prevent more serious damage and restore efficiency.

Practical Tips for Staying Cool While Reducing AC Strain

Close Curtains and Blinds

Blocking direct sunlight during the hottest part of the day can reduce indoor heat gain by up to 77%, according to the Department of Energy.

Cook and Use Appliances Wisely

Ovens, dryers, and dishwashers generate heat. Use them in the morning or evening to keep indoor temperatures lower.

Upgrade to a Programmable or Smart Thermostat

These devices optimize cooling schedules based on your habits and reduce strain on the system during peak heat hours.

Preparing Your AC for Future Summers

While this blog focuses on late summer, the lessons apply to all warm-weather months. Proactive care—including seasonal maintenance, proper insulation, and strategic thermostat use—helps your AC handle the challenges of outdoor heat year after year.

A properly maintained system will not only cool more effectively but also reduce the risk of costly mid-season breakdowns.

When it comes to comfort in Mechanicsburg, PA, having a reliable air conditioning system isn’t just a luxury—it’s a necessity. While the area doesn’t experience scorching desert heat, Pennsylvania’s humid summers and unpredictable weather patterns can make indoor temperatures feel oppressive without effective cooling. Whether you’re upgrading an aging system or installing a unit for the first time, buying a new air conditioner is a significant decision—one that impacts your comfort, energy bills, and even your indoor air quality for years to come.

Yet, despite the importance of this investment, many homeowners unknowingly make costly mistakes during the buying process. These missteps can lead to higher expenses, inefficient performance, or premature system failures. To help you make a confident and informed choice, we’re breaking down the top five mistakes people make when buying a new AC unit in Mechanicsburg—and how to avoid them.

1. Choosing the Wrong Size AC Unit

One of the most common (and most costly) mistakes is selecting a system that is either too large or too small for your home.

Why Size Matters

Air conditioners are measured in “tons,” which refers to their cooling capacity. You might assume that bigger equals better, but that’s far from the truth. An oversized AC unit will cool your home quickly but shut off before completing a full cycle—this is known as “short cycling.” It leads to inconsistent temperatures, higher humidity levels, and excessive wear and tear. On the other hand, an undersized unit will run continuously, struggling to keep up with demand, and ultimately overworking itself.

How to Avoid It

An HVAC professional should perform a Manual J load calculation to determine the proper size for your home. This calculation considers square footage, insulation levels, window size, orientation, number of occupants, and even local climate patterns in Mechanicsburg. Skipping this step or relying on rough estimates is a shortcut that can cost you in the long run.

2. Ignoring Energy Efficiency Ratings

Not all AC units are created equal when it comes to energy consumption. Choosing a model without paying attention to its efficiency rating can result in unnecessarily high utility bills.

Understanding SEER Ratings

The Seasonal Energy Efficiency Ratio (SEER) measures the cooling output of an AC unit divided by the energy it uses over a typical cooling season. The higher the SEER rating, the more energy-efficient the unit is. Federal regulations now require all new air conditioners to meet minimum SEER standards, but you still have options that offer significantly higher efficiency.

The Long-Term Impact

While high-efficiency models might come with a higher upfront cost, they typically pay for themselves over time through lower operating costs. In fact, the U.S. Department of Energy reports that upgrading from a 10 SEER system to a 16 SEER unit can reduce air conditioning energy use by up to 40%. That adds up—especially during hot, humid Pennsylvania summers.

3. Overlooking Ductwork Condition and Design

Many homeowners focus solely on the AC unit itself, but your ductwork plays a critical role in system performance. Ignoring this part of the system is a mistake that can undermine even the most advanced equipment.

Why Ductwork Matters

According to Energy Star, 20% to 30% of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. If your ductwork is outdated or improperly designed, you could experience uneven cooling, longer run times, and wasted energy.

What to Do About It

Before installing a new unit, have your ductwork inspected for leaks, blockages, and sizing issues. Proper sealing and insulation, along with correctly sized ducts, ensure your AC unit works as intended and delivers cool air efficiently throughout your home.

4. Not Considering Indoor Air Quality

Another mistake people often make is focusing only on temperature control and forgetting about the air they breathe. Indoor air quality (IAQ) should be part of the conversation when buying a new AC system.

Why It’s Important

A well-functioning HVAC system does more than keep you cool. It can help filter airborne contaminants, manage humidity, and create a healthier living environment. Poor IAQ has been linked to allergies, asthma, and other respiratory problems.

Enhancing IAQ with the Right System

Modern AC systems can be paired with advanced filtration options, dehumidifiers, UV lights, and other add-ons that improve indoor air quality. In a place like Mechanicsburg, where pollen and humidity levels can fluctuate seasonally, these enhancements can make a noticeable difference in your overall comfort and health.

5. Failing to Hire a Qualified HVAC Contractor

Finally—and perhaps most importantly—many homeowners make the mistake of hiring the wrong contractor or trying to go the DIY route when replacing their AC.

Why Installation Matters

Even the best AC unit will perform poorly if it’s not installed correctly. Improper installation can reduce system efficiency by up to 30%, according to the U.S. Department of Energy. That translates into higher energy bills, more frequent repairs, and a shortened lifespan for your new equipment.

What to Look for in a Contractor

Make sure your HVAC contractor is licensed, insured, and experienced with the type of system you’re considering. They should also offer a comprehensive consultation, perform a Manual J load calculation, and take the time to explain your options clearly. Transparency, professionalism, and local knowledge—especially of climate-specific concerns in Mechanicsburg—are key indicators of a reputable company.

Working with a trusted contractor not only protects your investment but gives you peace of mind that the job will be done right the first time.

Other Considerations When Buying a New AC

While those are the top five mistakes, here are a few additional points to keep in mind during the decision-making process:

Don’t Rush the Decision

Replacing your AC often happens under pressure—usually when your old system breaks down. But taking time to research your options, get multiple estimates, and understand your long-term goals is crucial. If possible, plan ahead before your system fails completely.

Think About Future Needs

Are you planning to finish your basement? Add on a room? Install solar panels? Thinking about how your cooling needs might evolve can help you choose a system that continues to serve you well.

Ask About Maintenance Plans

Even the best AC systems require regular maintenance to perform at their best. Ask your contractor about maintenance programs that include seasonal tune-ups, inspections, and priority service. Routine care can prevent small issues from turning into costly repairs.

Life in Mechanicsburg, PA, comes with its share of weather challenges. Whether it’s keeping your home comfortable through high humidity, managing unpredictable temperature swings, or maintaining indoor air quality, HVAC systems play a critical role in making day-to-day living comfortable. But recently, homeowners and contractors alike have been feeling the impact of a national issue that’s hitting close to home—the shortage of R-454B refrigerant.

This newer refrigerant, designed to replace older models like R-410A due to its lower global warming potential, is suddenly in short supply. As a result, HVAC contractors in Mechanicsburg and throughout the region are adjusting how they do business, serve their customers, and plan for the future. If you’re a homeowner confused or concerned about what this all means, this blog is for you.

What Is R-454B and Why Is It Important?

R-454B is a hydrofluoroolefin (HFO) blend refrigerant that was introduced to help meet new environmental regulations. As the HVAC industry moves toward more eco-conscious solutions, R-454B has emerged as a key replacement for R-410A in residential and commercial air conditioning systems.

Why is it such a big deal? Because it reduces the global warming potential (GWP) of refrigerants significantly—by nearly 78% compared to R-410A. The Environmental Protection Agency (EPA) and international environmental policies have pushed for these changes to minimize climate impact, and equipment manufacturers have followed suit.

The R-454B Shortage: What’s Going On?

Despite the good intentions behind its adoption, R-454B is now facing a serious supply crunch. Several factors have contributed to the current shortage:

• Increased Demand: As HVAC manufacturers switch to equipment compatible with R-454B, demand has surged. But production hasn’t yet caught up.

• Limited Production Facilities: Only a few chemical manufacturers globally produce R-454B, and their output capacity is still ramping up.

• Logistical Challenges: Shipping delays, international trade tensions, and regional transportation issues have slowed delivery timelines.

• Regulatory Hurdles: Approvals and certifications for R-454B-compatible equipment vary by state, sometimes causing bottlenecks in system rollouts.

According to recent industry reports, lead times for R-454B systems are up by as much as 60%, and many distributors are rationing what limited stock they do have. Mechanicsburg HVAC contractors are feeling the ripple effects—and so are local homeowners.

How Mechanicsburg HVAC Contractors Are Adapting

Despite these obstacles, HVAC professionals in Mechanicsburg are not standing still. They’re finding practical, proactive ways to work through the shortage and keep customers comfortable.

1. Stockpiling and Planning Ahead

Many local contractors began preparing months ago. By forecasting demand and pre-ordering R-454B units where possible, they’ve been able to minimize disruptions. Those with strong supplier relationships have secured early shipments and built up inventory where possible.

2. Educating Homeowners About Alternative Options

Not all HVAC systems require R-454B—yet. Many homes still use systems that run on R-410A or even older refrigerants. Contractors are explaining the pros and cons of upgrading now versus waiting, helping homeowners make informed decisions based on system age, budget, and efficiency goals.

3. Prioritizing Repairs Over Replacements

In light of the refrigerant shortage, HVAC teams are placing greater emphasis on maintaining and repairing existing systems. A well-maintained R-410A unit might still have several years of reliable service left. Mechanicsburg contractors are offering enhanced maintenance programs to extend the lifespan of older units, ensuring continued comfort without an immediate system upgrade.

4. Expanding Training and Certifications

Because R-454B is mildly flammable (classified as A2L), it requires new handling protocols and technician certifications. Local HVAC businesses are investing in training to ensure their teams are fully prepared to install and service R-454B systems safely and correctly when they do become available.

What This Means for Homeowners in Mechanicsburg, PA

If you’re a homeowner in Mechanicsburg, you might be wondering: What does all this mean for me and my air conditioning?

Here’s what you need to know:

1. You Don’t Need to Panic

There’s no need to rush out and replace your AC system if it’s still running efficiently. The refrigerant shortage doesn’t mean your home will be left in the heat—it just means HVAC contractors are adapting the way they deliver service.

2. Maintenance Is More Important Than Ever

Now is a smart time to schedule a tune-up or annual inspection. A well-maintained HVAC system runs more efficiently, uses less energy, and is less likely to suffer a breakdown. Plus, catching small issues early can prevent bigger repairs—or the need for a full system replacement—down the line.

3. Be Flexible With Installation Timelines

If you are in the market for a new system, be aware that installation times may be longer than usual. Contractors are doing their best to manage inventory and supplier schedules, but delays can happen. The earlier you get on a contractor’s schedule, the better.

4. Consider Long-Term Efficiency Goals

The refrigerant you choose today could affect your energy bills and environmental impact for the next 10 to 15 years. Local HVAC contractors can help you explore all available options, including high-efficiency systems that may qualify for rebates or financing.

Mechanicsburg, PA, is known for its mix of warm summers and chilly winters, which makes a well-functioning HVAC system essential for year-round comfort. But did you know that something as simple as pet hair and dust could be silently affecting the efficiency of your heating and cooling system? While it may seem harmless, accumulated pet hair and dust can cause more damage than you might think, leading to higher energy bills, reduced indoor air quality, and even costly repairs. In this article, we’ll dive deep into how pet hair and dust impact your HVAC system, the warning signs to look out for, and what you can do to protect your system and your home.

How Pet Hair and Dust Enter Your HVAC System

Pet hair and dust are practically unavoidable. Whether you have a playful Labrador, a fluffy Persian cat, or simply live in a home that accumulates dust, these tiny particles are constantly circulating through the air. When your HVAC system is running, it draws in air from your living spaces to heat or cool it before pushing it back out. Unfortunately, it also pulls in pet hair, dust, dander, and other pollutants.

Even with filters in place, finer particles can sneak through, especially if your filters aren’t regularly maintained. Over time, this accumulation begins to clog components within your HVAC system, affecting its performance and efficiency.

The Impact of Pet Hair and Dust on HVAC Components

Let’s break down exactly how pet hair and dust can impact the main components of your HVAC system:

1. Air Filters

Your HVAC system’s first line of defense is the air filter. Its purpose is to catch dust, pet hair, pollen, and other airborne contaminants before they reach the system’s more delicate components. However, if you have pets or a dusty environment, these filters can quickly become clogged.

• A clogged filter reduces airflow, making your HVAC system work harder.

• It can cause your system to cycle more frequently, which increases wear and tear.

• According to the U.S. Department of Energy, replacing a dirty filter can reduce your HVAC’s energy consumption by 5% to 15%.

2. Ductwork

Pet hair and dust don’t just stop at the filter; they can also settle in your home’s ductwork. Over time, this accumulation restricts airflow and diminishes indoor air quality.

• When ducts are obstructed, your HVAC system must work harder to push air through, leading to increased energy usage.

• The buildup can also become a breeding ground for allergens and bacteria, circulating contaminated air throughout your home.

3. Evaporator Coils and Condenser Coils

The evaporator and condenser coils are critical for cooling your home. Pet hair and dust can coat these coils, reducing their efficiency and insulating them from the air that needs to be cooled.

• A layer of dust as thin as 0.042 inches can reduce efficiency by up to 21%.

• Dirty coils lead to longer cooling cycles, increased energy costs, and potential overheating of your system.

4. Blower Motor and Fans

The blower motor is responsible for circulating air throughout your home. Pet hair and dust buildup on the fan blades can unbalance the motor, causing vibrations and premature wear.

• This extra strain can shorten the lifespan of the motor.

• A compromised blower motor reduces airflow, leading to uneven heating or cooling.

Warning Signs Your HVAC System Is Affected

Knowing the signs of pet hair and dust buildup can save you from unexpected breakdowns and high repair costs. Here are the key indicators to watch for:

• Reduced Airflow: If you notice less air coming from your vents, your system may be struggling to push air through clogged components.

• Increased Energy Bills: A clogged HVAC system has to work harder to maintain comfort, leading to higher utility bills.

• Frequent Cycling: If your HVAC turns on and off more than usual, it could be fighting against restricted airflow.

• Unusual Noises: Whistling or rattling sounds may indicate air is struggling to move through clogged ducts or a stressed blower motor.

• Hot or Cold Spots: Uneven temperatures in your home often signal blocked vents or restricted airflow.

Preventative Measures to Protect Your HVAC System

The good news is that preventing pet hair and dust from damaging your HVAC system is manageable with a few regular maintenance habits:

1. Change Air Filters Regularly

In a home with pets, it’s recommended to change your air filter every 1 to 2 months. High-efficiency particulate air (HEPA) filters can help capture smaller particles, protecting your system even further.

2. Clean Your Home Frequently

Regular vacuuming, dusting, and sweeping will reduce the amount of pet hair and dust circulating through your HVAC system. Consider vacuuming at least twice a week if you have pets.

3. Groom Your Pets Regularly

Brushing and bathing your pets often will significantly reduce shedding. For heavy shedders, grooming outside or in a designated area can limit how much hair ends up indoors.

4. Duct Cleaning and Maintenance

Schedule professional duct cleaning every 3 to 5 years to clear out accumulated dust and hair. If you have multiple pets, more frequent cleaning may be necessary.

5. Install Air Purifiers

An air purifier can catch hair and dust before it reaches your HVAC system, relieving some of the stress on your air filters.

6. Routine HVAC Maintenance

Regular maintenance ensures your HVAC system is clean and running efficiently. Professional inspections can catch minor issues before they escalate, extending the life of your system.

Why Regular Maintenance Matters

Routine HVAC maintenance not only helps to keep your system running efficiently but also prevents costly repairs. The EPA estimates that regular maintenance and cleaning can reduce HVAC energy consumption by 20% to 30%. Furthermore, well-maintained systems are less likely to fail during extreme temperatures, which is critical for comfort in Mechanicsburg’s diverse climate.

Living in Mechanicsburg, PA means experiencing a wide range of weather throughout the year. One day can bring a pleasant breeze and mild temperatures, and the next might hit with a wall of heat and humidity. Summers here are no joke—temperatures often reach the high 80s or 90s, with humidity levels that can make your home feel like a greenhouse if your air conditioning isn’t up to par.

If you’re starting to question whether your current AC system can handle another summer, you’re not alone. In fact, the time to think about your cooling system is before the real heat hits. The last thing you want is to discover your AC is on its last legs when the summer sun is beating down.

In this post, we’re breaking down the top 10 signs you need to schedule an AC installation before summer rolls in—and why acting now could save you time, money, and a whole lot of sweat.

1. Your AC Unit is 10-15 Years Old

Let’s start with one of the biggest indicators: age. The average lifespan of a central air conditioning unit is about 12 to 15 years, according to the U.S. Department of Energy. After that point, efficiency declines and the risk of major failures increases significantly.

Older systems are also far less energy-efficient than newer models. Modern AC systems can be up to 30-50% more efficient, according to Energy.gov. So if your unit is in that 10 to 15-year range, it’s not just more likely to break down—it’s also likely costing you more in monthly energy bills.

2. You’re Noticing Higher Energy Bills

Speaking of energy bills—have they been creeping up lately, even though your usage habits haven’t changed much?

Aging or inefficient AC systems have to work harder to cool your home, especially during high heat and humidity. This increased workload leads to higher energy consumption, and ultimately, a more expensive monthly bill.

If you’re seeing spikes every summer, it might not be just the temperature to blame—it could be your AC. Upgrading to a modern, high-efficiency system can reduce your cooling costs by 20% to 40%, according to ENERGY STAR®.

3. Your Home Feels Unevenly Cooled

Do you notice hot and cold spots in different rooms of your home? Maybe the living room feels like an icebox while the upstairs bedrooms are stifling?

This is a sign that your current system isn’t distributing air properly. It could be due to poor airflow, clogged ducts, or a struggling AC unit that simply can’t keep up.

While a service call can sometimes resolve airflow issues, uneven cooling is often a red flag that your system is outdated or improperly sized. A professional AC installation ensures you get a unit that matches your home’s cooling needs, eliminating those frustrating hot spots.

4. Frequent Repairs Are Adding Up

Here’s a question to consider: how many times have you had to call for AC repairs in the last two years?

If your answer is “more than a couple,” your system is likely on its last legs. While repairs are normal over time, frequent breakdowns often point to systemic issues—and the cost of ongoing repairs can quickly add up to more than the cost of a new installation.

According to HomeAdvisor, the average repair cost ranges from $150 to $600 per visit, depending on the issue. If you’re averaging two or three visits per season, that’s money you could be investing in a reliable, efficient system instead.

5. Your System Uses R-22 Refrigerant

If your current system was installed before 2010, there’s a good chance it uses R-22 refrigerant, also known as Freon. This substance was officially phased out in the U.S. due to its harmful environmental impact.

As a result, R-22 is now extremely expensive and difficult to find, and repairs involving this refrigerant are costly and unsustainable. If your unit requires R-22, it’s time to seriously consider a replacement with a modern unit that uses eco-friendly, widely available refrigerants like R-410A.

6. Your AC is Loud or Making Strange Noises

No air conditioner is completely silent—but if you’re hearing banging, rattling, screeching, or grinding, something isn’t right.

These noises can signal a range of issues, from loose parts to motor failure. Sometimes repairs are possible, but if the system is older or if noise is a persistent problem, it may be more cost-effective to replace it altogether.

Newer models are designed with quieter operation in mind, with many operating under 60 decibels—roughly the noise level of a normal conversation.

7. Humidity Levels Are Out of Control

In Mechanicsburg, PA, humidity is a real concern during the summer months. Your AC system should help manage indoor humidity, not just temperature. If your home feels sticky, damp, or muggy, it may be a sign that your system is struggling.

High indoor humidity can also lead to other issues, like mold growth, poor air quality, and musty odors.

New air conditioners are equipped with better humidity control features that keep your indoor air comfortable and healthy, reducing the likelihood of moisture-related problems.

8. You’re Planning a Home Renovation or Addition

Adding square footage to your home? Planning to finish the basement or attic?

These changes affect your home’s overall cooling load. Your existing AC system may not be properly sized to handle the added space, which could lead to inefficiency and discomfort.

Installing a new system (or upgrading to a zoned HVAC system) ensures that every room—new or old—stays cool and comfortable. A professional will perform a Manual J Load Calculation to determine the correct system size for your home.

9. Poor Indoor Air Quality

Your air conditioner does more than cool your home—it also plays a role in filtering and circulating air. If you’re noticing more dust than usual, worsening allergies, or stale air, your current AC system may be failing to do its job.

Newer systems come with enhanced filtration and ventilation options, including HEPA filters and UV light systems, which significantly improve indoor air quality.

This is especially important for households with children, elderly residents, or people with respiratory conditions.

10. You’re Ready for Smart Technology and Energy Efficiency

Today’s homeowners are looking for more than just cool air—they want smart, connected, and eco-friendly solutions. If your current AC doesn’t integrate with a smart thermostat or can’t be scheduled remotely, you’re missing out on major convenience and savings.

Smart HVAC systems offer features like:

• Wi-Fi connectivity

• Automated scheduling

• Energy usage tracking

• Remote diagnostics

These tools help you optimize your energy use and even extend the lifespan of your system. Many smart thermostats can save homeowners an average of 10-12% on heating and 15% on cooling, according to Nest Labs.

The Best Time for AC Installation? Before the Rush

Scheduling an AC installation before summer arrives isn’t just smart—it’s strategic. Spring is typically the ideal time for AC upgrades, as HVAC companies tend to have more availability and can perform thorough assessments without the pressure of emergency service calls.

By acting early, you can:

• Beat the summer installation rush

• Avoid uncomfortable heatwaves

• Take advantage of seasonal promotions or rebates

• Get personalized recommendations from technicians with ample time

And perhaps most importantly, you’ll enjoy the peace of mind that comes with knowing your home will be cool, comfortable, and efficient all summer long.
