To keep your HVAC system running smoothly, our HVAC service and repair experts in Phenix City offer these simple troubleshooting tips:

Essential troubleshooting tips for five common HVAC issues

• Thermostat Issues?

Your HVAC system should turn off when your thermostat reaches the desired temperature. However, if it continues to run, your thermostat might be malfunctioning. Check the set point against the actual room temperature. If there's a noticeable difference, and the heating or cooling has been running for some time, you may need a new thermostat. 

Keep in mind that a typical thermostat lasts ten years, and they can gradually deteriorate with age. If something seems off, have a trusted HVAC service professional check the thermostat to see if it needs replacement.

• Power Failures?

If your HVAC system won't turn on, it might be due to a tripped circuit breaker caused by a power surge. In this case, simply reset the breaker to restore power. Check the power cord for damage or fraying caused by rats or other pests. Additionally, check the power outlet by plugging in another device. If the outlet doesn't work, it's the source of the problem, not your HVAC system.

• Short Cycling?

HVAC short cycling is a common problem with multiple root causes. It occurs when an underlying issue abruptly stops the HVAC system's operation, leading to short cycles. To avoid short cycling, check for clogged air filters, faulty electrical connections, and frozen evaporator coils, among other causes. Some causes of short cycling can be resolved by homeowners, while others require professional HVAC repair or even complete HVAC replacement.

• Noisy HVAC Unit?

Loud and obnoxious noises from your HVAC system can be a sign of moderate to serious issues. These noises often indicate the need for HVAC repair or replacement. For example, a pounding noise could indicate a malfunctioning compressor, a shrill noise could indicate a faulty fan motor, and a screeching or squealing sound could indicate a broken blower fan motor.

• Clogged filters?



Clogged air filters can limit airflow, causing the air handler to work harder. This can result in the heat exchanger overheating and shutting off early, raising your energy costs and reducing indoor air quality (IAQ). To avoid clogged filters, clean them regularly.
