As you raise or lower the temperature in your Lakewood, Texas, home, your furnace or air conditioner should kick on in response to the adjustment on the thermostat. If you hear any strange sounds coming from the HVAC system, you may need to bring in a professional to take a closer look.

Thumping or Banging Sounds

When you hear banging, thumping, or even rattling sounds, these can indicate an issue with the motor or blower. A component may have come loose and is bumping against something else, or the motor could have broken and have a part banging against the edge of the housing. A professional HVAC technician should always handle assessment of the motor and reassembling or replacing a broken part.

Clicking Noises

Hearing clicking noises is normal when you first turn on the system or when it shuts off after reaching the set temperature. However, continuous clicking from the compressor outside or the control panel of the system can indicate a problem. You could have a defective relay or an electrical component that is shorting out.

Rattling Sounds

The rattling sounds often come from the outdoor unit of an air conditioning system. This type of sound might indicate loose hardware or a motor that is near failure. When the rattling is very loud, it’s especially concerning, so turn off the system and call an HVAC professional right away.

Screeching Noises

Hearing a screech or squeal from your HVAC system can be very jarring and unpleasant. The most common causes of squealing include worn out motor bearings and broken belts. Replacing a belt or motor bearing isn’t too expensive, but since these components are found within the furnace, it’s important to leave this task up to a skilled professional.
