Few things are more frustrating for a homeowner than discovering that your air conditioner is not working. The first sign that an AC is on the fritz usually sets off red flags that put any wallet on edge.

While AC issues can be costly, several simple issues may prevent your air conditioning from working correctly. The solutions to these problems are easy to fix and will only take a few minutes to check.

Let’s take a closer look at some of the main reasons why your HVAC isn’t working properly.

Top Three Causes Of Air Conditioning Failure

1. Your Thermostat

Your thermostat, not the AC unit itself, can be the problem. Check to make sure that it is set correctly and that it is on “cooling.”

Sometimes, especially if the power in the house has reset recently, it will revert back to its installation settings.

Many new thermostats also have batteries. Check to see if your battery needs to be replaced. If you have a smart thermostat, check the app settings to ensure nothing has changed.

If your thermostat is set correctly and does not need a battery, try turning it down by 10 degrees. This large enough of a change in the setting can jumpstart a thermostat and help it reset and start working again.

While this does not always work, it is something you can try. If the air conditioner turns back on, readjust the temperature to the setting you desire after it runs for at least one cycle.

However, if you find that your thermostat isn’t the issue, it may be time to reach out to an HVAC specialist in Dallas for a maintenance check or repairs.

2. The Circuit Breaker

If you have popped the circuit for your AC unit, it will not work. Check the indoor breaker box to see if the circuit is popped. If so, reset the circuit, and your unit should begin working.

Some outdoor units also have a circuit breaker. Check the outdoor circuit to see if the fuse is popped. If it is, reset the circuit, and your air should turn on.

If your interior circuit breaker continues to pop, you may need to call an electrician to change the circuit or upgrade it to a stronger circuit.

3. Clogged Filter

Your air conditioning unit relies on airflow to work properly. If your filter is dirty or clogged, it cannot move the air effectively through the system. Check your interior filter to make sure that it is clean. Replace if necessary.

While checking filters, your outdoor unit may also have a filter. If so, check to make sure that the filter is clean. Also, you should remove any debris that may be around or on top of your unit. Airflow restrictions can cause the A/C unit to fail.

How often should you replace your HVAC filter? Start by checking your filter monthly to truly understand how quickly your unit filters collect dust. Keep in mind that in order to keep your HVAC running smoothly, you’ll want to change out your filters every 90 days.
