Top Air Conditioning FAQs in Mechanicsburg, PA

If your air conditioner is blowing warm air, it could be due to several issues, such as a refrigerant leak, a clogged air filter, or a malfunctioning compressor. Another common reason is that the thermostat is set to “heat” or “fan” instead of “cool.” Checking these settings or replacing the filter can sometimes resolve the problem. However, if the issue persists, it’s best to have a licensed HVAC technician from Jeffrey A. Wilbur Plumbing, Heating & Air Inc. inspect the system and make any necessary repairs.

The cost to repair an air conditioner can vary based on several factors, including the type of problem, the age of the unit, and the specific parts that need to be repaired or replaced. Common issues like refrigerant leaks, faulty thermostats, or worn-out components can require different levels of repair. To get an accurate estimate, it’s best to have a professional HVAC technician inspect the system and diagnose the problem. Proper maintenance can help reduce the need for costly repairs in the future.

Most air conditioning units last between 10 to 15 years with proper maintenance. Factors such as the quality of the system, how often it’s used, and regular maintenance can all affect the unit’s longevity. If your AC is nearing the 10-year mark and experiencing frequent breakdowns, it may be time to consider a replacement. Our team can help you assess whether it’s worth repairing or replacing your system.

We recommend scheduling AC maintenance at least once a year, ideally in the spring before the summer heat kicks in. Regular tune-ups help identify small issues before they become major problems, improve energy efficiency, and prolong the life of your system. Annual maintenance will also ensure that your air conditioner is working at peak performance during Mechanicsburg’s hot and humid summer months.

Unusual sounds like banging, rattling, or hissing coming from your air conditioner can indicate several problems, including loose parts, debris in the system, or refrigerant leaks. A buzzing sound may point to electrical issues while grinding noises can mean a problem with the motor. Strange noises should never be ignored, as they often signal a need for professional attention to prevent further damage.

Choosing the right size air conditioner is essential for energy efficiency and comfort. An AC that’s too small will struggle to cool your home, while one that’s too large can lead to short cycling and excess humidity. The size you need depends on factors like your home’s square footage, insulation, and window placement. At Jeffrey A. Wilbur Plumbing, Heating & Air Inc., we perform load calculations to determine the ideal size unit for your home.

The best time to replace your AC unit is during the cooler months of spring or fall when HVAC companies have more availability, and you won’t be relying on your system as much. Replacing your unit before the summer heat ensures that your new system will be ready to keep you cool when you need it most. Additionally, you may be able to take advantage of off-season discounts or promotions.

To lower your cooling costs during the summer, you can take a few simple steps. First, schedule regular maintenance to ensure your system is running efficiently. Consider using a programmable thermostat to reduce energy use when you’re not home. Sealing windows and doors, closing blinds during the day, and using ceiling fans to circulate air can also help reduce the load on your AC. Upgrading to an energy-efficient unit is another long-term way to save on energy bills.

If your air conditioner is cycling on and off frequently, this is known as short cycling. It could be caused by an oversized system, a thermostat issue, or a clogged air filter. Short cycling not only affects comfort but also increases wear and tear on the unit. It’s important to address this problem quickly to prevent further damage and higher energy bills. Our technicians can diagnose the root cause and suggest the best solution.

An air conditioner can freeze up for several reasons, most commonly due to restricted airflow or low refrigerant levels. A dirty air filter, blocked vents, or a malfunctioning blower can prevent proper airflow, causing the evaporator coil to freeze. Low refrigerant can also lower the temperature inside the unit, leading to ice formation. If you notice your AC freezing, it’s important to turn it off and let it thaw before having a professional inspect the system. Regular maintenance and cleaning can help prevent this issue and keep your AC running smoothly.

Some key signs that it’s time to replace your AC include frequent repairs, rising energy bills, inconsistent cooling, or if the unit is over 10-15 years old. If your system is struggling to keep your home comfortable or you notice unusual sounds or odors, it may be more cost-effective to replace the unit rather than continue with repairs. Our team can help you evaluate whether it’s time for a new AC system.

Yes, a dirty air filter can significantly reduce your air conditioner’s performance. It restricts airflow, causing the system to work harder, which can lead to higher energy bills and potential damage to components like the compressor. Changing your filter every 1-3 months, especially during peak cooling season, is a simple way to keep your system running efficiently.

Improving AC efficiency involves regular maintenance, sealing air leaks, and ensuring proper insulation. Keeping the area around the outdoor unit clear of debris and regularly cleaning or replacing air filters are also important. Additionally, using ceiling fans and setting your thermostat a few degrees higher can reduce the load on your system, helping it run more efficiently.

Whether a central air system or a ductless mini-split is better depends on your home’s layout and your cooling needs. Central air systems are ideal for homes with existing ductwork and can cool larger spaces more evenly. However, ductless mini-splits offer flexibility and energy efficiency for homes without ducts or for targeted cooling in specific rooms. Our team can help you determine which option is best for your home in Mechanicsburg.

Water leaking from your AC is often caused by a clogged drain line, a frozen evaporator coil, or a damaged drain pan. In some cases, the system may be low on refrigerant, causing the coil to freeze and thaw. Leaks should be addressed promptly to avoid water damage and mold growth. If you notice water pooling around your AC, contact us for a professional inspection.
