Troubleshooting Your Air Conditioning Unit When It Is Not Working

When your central air conditioning system stops working, you may wonder about the source of the problem. There are any number of reasons that your air conditioner is not working, and performing basic troubleshooting will get you to the root of the problem so you can get it fixed quickly.

The Air Conditioner Won’t Come On

When your air conditioner won’t come in, the problem is most likely the thermostat. If you have tried checking thermostat and see that there is no readout on the dial, this is likely the cause of the problem. In some cases, the unit may not be properly receiving electrical power.

Check the thermostat to make sure it is in the “cooling” position and that there is no timer delay in the unit.

The Air Conditioner is Blowing Warm Air

The most likely cause of warm air blowing from your unit is that your central air conditioner needs charged. This is a simple problem to fix, and a certified technician can refill your unit with Refrigerant quickly. When a unit needs Refrigerant charged, it will often not work properly.

The second cause of air conditioning systems blowing hot air is clogged or blocked air filters. In this case, the cool air will be blowing but unable to get through the dirty filters. Replacing your filter is the best way to remedy this problem. Check outside to make sure there is no debris or leaves in the exterior unit preventing air flow.

Clogged Condensation Lines

Mildew, mold or even insects can clog your condensation lines and affect the performance of your air conditioning unit. A certified technician will clean these lines as part of regular maintenance on your air conditioning unit, making sure everything is functioning as it should.

The Unit is Frozen

A frozen unit occurs when there is improper airflow in the air conditioner, causing cold air to remain inside and freeze the coils. The easiest way to prevent this is to have the coils and blower fan checked for malfunction. A faulty control relay will cause the exterior unit to continue blowing even when the unit is turned off, causing the unit to freeze and not work properly.

Regular maintenance on your central air conditioning unit is key to enjoying your system year round. A certified technician can perform seasonal maintenance, ensuring that all of the components are working properly and your system will remain operational.

Getting regular maintenance means avoiding huge repair bills later. Winter weather can do a number on your unit, causing damage that most people don’t realize until the unit stops working. The key is to schedule your maintenance early to enjoy uninterrupted service. Many people schedule their maintenance calls during the end of the spring season to avoid the rush during the hottest summer months.
