Having a home where you can cool off makes the warmer months of the year far more enjoyable. Unfortunately, air conditioning systems can break down from time to time and lead to stuffy and uncomfortable indoor environments. To help you determine if you need air conditioning repairs, here are a few common signs that indicate a system issue.

How to Tell if Your Air Conditioner Needs to Be Repaired

1. Blowing Warm Air

Warm air blowing from the vents is the biggest red flag that something is wrong with your AC. The unit's compressor could be faulty, or the system could be low on refrigerant. It might also be a problem with a broken return duct that is drawing in warm air from outside or the attic.

2. Making Unusual Noises

An air conditioner should be relatively quiet. The presence of strange noises is a sign that air conditioning repairs are needed. Squeaking or squealing could mean a belt has come loose or an internal part needs to be lubricated. A grinding noise can indicate broken bearings in the motor, or a buzzing could be a symptom of a faulty compressor, loose parts, or a leak in the refrigerant.

3. Has Reduced Airflow

Another warning of possible compressor problems is a noticeable reduction in airflow from the vents. If the airflow is strong and consistent in some rooms but not others, the source of the trouble is likely with the ductwork. Dirt, dust, dander, and other debris can easily build up within your ducts and impede the clear passage of air, so be sure to have your ducts cleaned every two to five years.
