The Most Common Late-Season AC Repairs

As the heat of the summer begins to transition into the first signs of cooler weather to come, it can be tempting to ignore AC issues. However, it can save you significant time and money in the long run if you contact Reliant Heating & Air Conditioning for your Clearwater heating and cooling repair needs. With 20+ years of combined heating and cooling experience, we have the tools, training, and expertise to handle whatever HVAC job you need a hand with, giving you the confidence that your system is in capable hands and your wallet is in good shape.


Clogged Air Filters

One of the most common late-season AC repairs we see yearly is caused by clogged air filters. Your air filter works hard to improve indoor air quality by trapping dust, pollen, pet dander, and other debris and preventing them from circulating throughout your home. By the end of the season, your air filter could easily become clogged from excessive amounts of debris covering the surface.


Adequate airflow is essential for your HVAC system's energy efficiency and overall performance. Rising energy bills might indicate that your unit works harder than usual to keep your home comfortable. You can increase the lifespan of your heating and cooling system by changing your air filters at least once every three months. If you live in an environment prone to higher levels of airborne contaminants, replace them more frequently for the best results. Regular maintenance is key to keeping your system running smoothly and your home comfortable.


Short Cycling

A typical HVAC cycle lasts between 15 and 20 minutes and occurs around two to three times per hour. "Short cycling" is a term that refers to your air conditioner turning on and off frequently without completing a full cooling cycle. When this happens, it is crucial to contact the professionals at Reliant Heating & Air Conditioning for repairs. Prolonging the process of solving the issue can quickly lead to minor repairs becoming expensive problems to fix as internal parts become damaged.


Thermostat Malfunctions

It might surprise you to learn that a malfunctioning thermostat is a common culprit of late-season AC issues that require repairs. Is your home still using an outdated manual model? If so, Reliant Heating & Air Conditioning can upgrade your home with a smart thermostat in no time!


Benefits of Smart Thermostats:

  • Energy savings because they adjust the temperature even when you forget to
  • Increased lifespan for your HVAC equipment because it runs less frequently 
  • Easier to adjust because you can do it from a phone or smart device 
  • More energy efficiency because you aren't running your HVAC system needlessly


Capacitor or Relay Failures

If your AC is not turning on, short-cycling, or making clicking noises, your system likely needs repairs because the capacitor or relay has failed. These two components are essential for your AC to start and run successfully. These parts frequently wear out during the summer due to excessive wear and tear.
