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.
