Of course, some problems will need a professional to fix. If an issue is beyond your skills, don’t try to fix it yourself, or you could cause more damage that is even more expensive to put right. Know when to admit defeat and call in Emergency AC Repair

Check For Dirty Air Filters

A dirty filter can cause problems like:

  • Low airflow from air vents
  • Ice on refrigerant lines
  • Frozen evaporator coil
  • Water leaking from your AC
  • Inadequate cooling
  • Higher than normal energy bills
  • Equipment failure

Take a look at your air filter. If it looks dirty or clogged, replace it. A dirt filter suffocates the AC unit. The layer of dirt on the filter limits the amount of air that your AC unit is able to breathe in. When the AC doesn’t enough airflow, it can cause a lot of different problems or even complete system failure. 

Check Your Thermostat Settings

Having your thermostat in the wrong settings can cause problems like:

  • Warm or hot air coming from the air vents
  • AC won’t turn on

Go to the thermostat and double-check it is set to cool and not heat. It sounds silly, but a lot of AC repair callouts are made to units that aren’t working that turn out to be set to heat and not cool. This happens a lot, especially as we move from heating to cooling season. 

Check Your Air Conditioning Circuit Breakers

If the air conditioning won’t turn on, then it could be a tripped breaker. Go to the main electrical panel in your home and check for any circuit breakers that aren’t in the on position. If your circuit breakers are clearly labeled, look for one that is labeled AC or Air Conditioning. 

If the circuit breaker for the AC is tripped, push it firmly into the on position, and try turning on the AC again. If the breaker immediately trips again once you run the AC, do not try to flip the circuit breaker again. You will need to call a professional to look at the unit, as there may be a larger electrical problem. 

Check Your Outdoor Unit

A dirty outdoor unit can cause problems including:

  • Higher than normal energy bills
  • Warm air coming from the air vents
  • AC not providing adequate cooling
  • Frequent repairs

Go outside and look at your outside AC unit. If there is a layer of dirt on the outside of the unit, you can use a hose on a gentle setting to shift the dirt. If you see a thick layer of dirt on the unit, it’s better to call a professional for a deep clean.
