When it’s summer, your home should be a sanctuary. However, if your cooling system isn’t performing the way it should, you could be facing a rather uncomfortable season under the sun. Fortunately, most HVAC problems can be spotted early and resolved with proactive A/C repair. To help you avoid emergency breakdowns, here are some common air conditioner issues that you should watch for and how they might be fixed.  

5 Common Signs Your Air Conditioner Needs Professional Repair

1. Insufficient Cooling

If you feel air coming through the ventilation, but it’s not cold, check to make sure the HVAC system is set to “cooling” mode. Other possible problems include a refrigerant leak, faulty thermostat, or dirty condenser coils.

2. Reduced Airflow

When there is little airflow through your home, check all of your vents to make sure they aren’t blocked or obstructed by furniture. You might also feel around the ductwork to see if there are leaks that need to be sealed with duct tape. Otherwise, you may need to have the blower fan or condenser professionally serviced.  

3. Icy Condenser Coils

The outdoor unit of an A/C system—known as a condenser—disperses refrigerant through a series of coils. This refrigerant absorbs heat to produce cool air. If the coils appear frozen or icy, however, there is likely a refrigerant leak that is causing a drastic change in the surface temperature. Usually, the best fix for this problem is to have an HVAC contractor repair the leak and recharge the refrigerant.

4. Strange Noises

The only noise you should hear from your air conditioner is the slight whirring noise of the motor and fan inside the unit. If you hear clanging, screeching, or grinding, it’s possible that a part is loose and needs to be adjusted or replaced. Hissing, on the other hand, is usually a sign of a refrigerant leak.

5. High Energy Bills

When an HVAC system overheats, it may turn off. However, it will turn back on soon after to produce cool air, as programmed. This frequent cycling can result in excessive energy loss and higher power bills. In these situations, it’s best to have an A/C repair company pinpoint and fix the cause of the overheating—such as an incorrectly-sized unit, broken parts, and system blockages.
