Scary HVAC Sounds That You Should Not Ignore:

  • Clicking Sound

 Clicking sounds are normal when your HVAC system turns on or off. Clicking noise in the HVAC system can occur for several reasons. One possible cause is difficulty with the relay procedure. 

A repetitive clicking noise could indicate a problem with the thermostat, which controls the temperature, or an electrical issue with the HVAC. In this case, it is best to turn off your HVAC system immediately and contact a trusted professional for furnace repair Carrollton TX  for help.

  • Hissing Sound

 If you hear a hissing sound coming from any compo nent of your system, it could be a sign of a minor to severe air duct leak in your home. This air leak might occur when the air filter is the incorrect size for your system. 

Other possible causes of the hissing sound include a faulty valve, a refrigerant line leak, or high compressor pressure. Whatever the problem of your Carrollton Heating and Air unit is, contact HVAC professionals as soon as possible to resolve, it because it impacts the operation and efficiency of your HVAC system.

  • Banging Sound

One of the most common sounds that you can hear coming from your HVAC system is a loud banging. If your hvac system is making a loud noise from the inside, it could be due to a faulty fan motor.

If the banging sound comes from your HVAC system’s outside unit, the cause could be a broken or loose component. It could also be due to a faulty compressor.

  • Buzzing Sound

Never ignore a buzzing sound coming from your HVAC system. This sound could indicate excessive vibration. Check your unit’s connecting parts and tighten any loose ones.
