Don’t Ever Ignore These 4 Ductless Noises in Fresno, TX

You probably get used to the sounds your Fresno, TX ductless air conditioning system makes and know what’s normal and what’s not. However, it’s important to understand the sounds and what they mean so you know when to take action. Take a look at the list below of ductless AC noises you should never ignore, and call us when they happen.

1. Rattling

Loose parts inside either unit of your ductless cooling system can produce a rattling sound during operation. You’ll need a professional technician to inspect the system, find the damaged parts and make repairs to stop the noise and the consequences the bad part could cause.

2. Hissing

Air bubbles in the refrigerant lines can cause hissing noises during cooling cycles. This hissing usually indicates a leak or low refrigerant levels within the ductless system. Refrigerant leaks are hazardous and low refrigerant can lead to no cold air.

3. Grinding

Grinding sounds inside the ductless system may indicate dry or worn bearings. The system produces these grinding noises as the bearings turn and move against other parts improperly. Contact our service technicians to inspect, lubricate or replace these bearings.

4. Buzzing or Humming

When your ductless system makes loud and unusual humming or buzzing noises, these are usually an indication of an electrical problem. You could have a loose connection or damaged wiring inside the system, creating these noises. Electrical issues are serious problems requiring immediate AC repair as they can cause the system to stop and create safety hazards for your home.

Knowing what’s normal and what isn’t can make a world of difference for the health and safety of your ductless system. If your ductless AC makes loud or unusual sounds, call our experts at Davis Air Conditioning & Heating, Inc. for skilled AC repairs so we can keep your Fresno, TX home comfortable this summer.
