6 Common Air Conditioning Issues and Troubleshooting Tips

Many homeowners make the error of waiting until that first summer day to turn on their HVAC or air conditioner, only to discover it’s not working.

Don’t be that homeowner. Instead, go into the summer months fully prepared by identifying common air conditioner problems before the heat arrives.

1. Thermostat Problems

More often than not, homeowners will face thermostat problems at least once. If your thermostat doesn’t turn on, the chances are that the batteries are dead.

To troubleshoot, first, change the batteries. Then, make sure your thermostat is set to “cooling mode” and check to ensure it is set to a temperature lower than the current temperature.

If your thermostat still doesn’t work, call for professional help.

2. Dirty Air Filters

For your AC to properly work, you need to have a clean air filter. Without a clean AC filter, your HVAC system will:

  • Produce weak airflow
  • Produce poor air quality
  • Lead to mold growth

Therefore, it’s important to change your filter at least once every six months. However, you may want to change your filter once a month during allergy season.

3. Frozen Condenser Coils

Frozen HVAC coils will lead to poor indoor air temperatures as the coils are used to transfer hot air from outside of your home.

If your air conditioning condenser coils are frozen, you will need professional help, as this problem requires extensive repairs.

4. Refrigerant Leaks

Your air conditioning refrigerant is another element of your system that transfers hot temperatures from outside your home. If you notice your AC unit is struggling to cool your home, you may have a refrigerant leak.

Repairing an air conditioning leak is tricky, and it is safest to call someone for repairs.

5. Water Leaks

If you don’t service your HVAC system often, eventually, the drains in your air conditioning unit can become clogged. As a result, it will leak water.

When this happens, it’s important to call for maintenance, as continuing to run your air conditioning unit will lead to more damage.

6. Tripped Circuit Breakers

If your circuit breaker keeps tripping, it may be because of a dirty air filter. Try changing your air filter first to see if this resolves the issue.

If not, the problem could be much more serious.
