Signs You Need an HVAC Repair
Here are some of the symptoms of a failing HVAC system that needs professional repairs:
- Failure to turn on: A system that won’t power on likely has a thermostat, power, or control board failure, which our technicians can diagnose and repair.
- Strange noises or odors: Grinding sounds typically indicate a failing motor, and burning smells are often a sign of an electrical issue.
- Weak airflow or uneven temperatures: Weak airflow often indicates a severely clogged filter or a struggling blower motor.
- Constant running or cycling: A system that runs constantly or cycles improperly is often a sign of incorrect refrigerant levels or a thermostat malfunction.
