As the summer uppercase and the heat becomes more intense, we rely more and more on our air conditioning units to keep our homes cool and comfortable. However, it can be incredibly frustrating when your AC suddenly stops working, especially when you have no idea why. Before you call an HVAC repair service, there are a few things you can do to troubleshoot the problem yourself.

In this blog, we will discuss the five most common air conditioning system problems and how you can fix them.

5 Most Common Air Conditioning Problems

AC Running Constantly

One of the most common air conditioner problems is when the unit runs constantly. This can be due to a number of issues, including wrong thermostat settings, a dirty filter, or a tripped breaker.

Air Conditioner Problems Caused By Wrong Thermostat Settings

If your air conditioning unit is running constantly, check your system and thermostat settings to ensure they are set correctly. If your thermostat is set too low, your AC will continuously run in an attempt to reach that temperature setting. Conversely, if your thermostat is set too high, your central air conditioning may not turn on at all.

AC Problems Caused By A Dirty Air Filter

Another common issue is dirty air filters. If your air filters are clogged with dirt and debris, they can reduce airflow through air ducts and cause your air conditioner system to work harder than it needs to. This can result in increased energy bills and even damage to your unit.

Central Air Conditioner Problems Caused By A Tripped Breaker

Lastly, check your circuit breaker to see if it has tripped. If the breaker has tripped, it could be due to a power surge or overload. Reset the breaker to see if this solves the problem.
