4 Noises You Never Want Your AC to Make

by | Dec 14, 2018 | Heating & Air Conditioning

As your HVAC in Sauganash ages, you’ll begin to notice things you didn’t see before, and we hope they’re good things indeed. However, if you’re starting to see less pleasant signs, this list is important. If your AC unit is making one or more strange sounds, call for repairs and maintenance.

Buzzing and Clicking

A clicking or buzzing noise usually indicates problems within the electrical system. When signals malfunction, the control panel constantly tries to turn switches on and off. While a new thermostat will resolve many problems, it’s important to get the wiring checked as well.

Squeaking and Squealing

Either of these noises show that the fan belt or the motor may be failing. Fan belts may stretch depending on humidity levels and temperature, but when motors fail, they usually have to be replaced.

Whistling Sounds

Whistling sounds indicate insufficient airflow. Low airflow has a variety of causes, such as leaking ducts, dirty air filters, or a failing blower. Call us to determine the cause of the blockage.

Banging and Clanging

When your Sauganash HVAC makes banging noises, there’s probably something misplaced or loose within the system. While it may be a small part, such as a screw that needs tightening, it’s just as likely to be an issue with the blower, compressor, or fan. To be on the safe side, call us for a check-up.
