5 Common AC Maintenance Problems in the Summer

Aug 1, 2025

Sweltering summer days often call for a quiet afternoon inside, enjoying the AC as you nap, read a book, or work on projects. And there’s nothing worse than settling in for this relaxation and realizing it’s just as hot inside as it is outside.

AC problems like these are common in the summer, but that’s often simply because the proper proactive measures haven’t been taken. Let’s go over some common summer air conditioning problems and discuss how thorough AC maintenance services can help you steer clear of them.

Common Problems that Require AC Maintenance Service

Many homeowners run into these problems throughout the summer, but staying on top of maintenance before the hotter months hit can help you avoid many of them.

1. Refrigerant Leaks

Refrigerant leaks reduce efficiency, forcing your AC to work harder to keep your home cool. Prolonged leaks can also lead to long-term system damage or health risks. In a professional AC maintenance service check, your technician can take care of any leaks, address any early signs of a drip, and recharge your refrigerant so your home stays safe and cool.

2. Dirty Air Filters

When air filters become clogged with dust and debris, your AC has to work harder to push air through, reducing energy efficiency and air quality. A professional technician can replace or clean filters regularly, ensuring proper airflow and extending the life of your system.

3. Damaged Compressor

The compressor is at the heart of your AC system, and when it’s damaged, your unit can’t cool properly. Issues with refrigerant or electrical wiring, or even just normal wear and tear, can cause your compressor to fail. Routine AC maintenance service can help you identify these problems early, preventing further damage or expensive repairs and replacements.

4. Condenser Unit Problems

The condenser unit, usually located outside, is vulnerable to dirt, debris, freezing, and other weather-related damage. When it’s blocked or broken, your AC’s cooling power drops significantly, and you risk further damage throughout your system. An expert technician can clean the unit, check for issues, and ensure it’s fully operational to handle the summer heat. 

5. Faulty Thermostat

Sometimes this issue isn’t with your actual AC unit, but instead with the thermostat. If you notice temperature inconsistencies, higher energy bills, or generally poor cooling, but your unit seems to be in good repair, check the thermostat. It may simply be set wrong, or you may need to recruit a pro to help fix a broken sensor or install a replacement.

Tips for Caring for Your System

Running into these issues in the dead heat of a Georgia August is never fun, so try these tips for keeping your AC healthy and running smoothly throughout the summer.

  • Change Air Filters Regularly: Filters need to be switched out about every three months, but consult the manufacturer’s instructions and your HVAC guys for specific advice on your unit and filter type.
  • Check & Clean Coils: Regularly give your AC unit a once-over to check for grime, damage, debris, etc., paying special attention to the coils. Be sure to give them a good cleaning or schedule a visit from your HVAC company when needed.
  • Schedule Annual AC Maintenance Service: A yearly AC check and tune-up before the summer heat sets in is a great way to address any problems early on and make sure your unit is ready to keep you cool until the fall.
