Diagnosing and Addressing Different Heater Noises
It can be very unsettling to hear loud or unusual noises from your heater. Especially if those noises come during the quiet hours of the night. If you’re hearing noises from your furnace or concerned about some of the sounds that it’s making, you’re not alone. This is a relatively common issue and one that can be caused by a number of things.
Some of them are easy to address and don’t indicate a major problem, others are more serious and require a professional to resolve. Here is some helpful information about different types of HVAC noises to help you address unusual furnace noises.
Loud Banging Noises
If you hear this sound, contact a professional to have your system inspected and cleaned as soon as possible. You can avoid this issue by having regular tune-ups, which will clean the burners and remove any concerning buildup.
Screeching or Squealing Sounds
A squealing sound from your heater usually indicates an issue with the blower motor. It could mean that some components are wearing out or it could simply mean that they’re misaligned. It could also mean that you have a loose fan belt or that your unit needs lubricant. If you’re comfortable tightening the fan belt or adding some lubricant, you can start by doing those things on your own.
If that doesn’t resolve the problem, you’ll want to contact a professional for a heater inspection. Whether it’s simply an alignment issue, a simple maintenance issue, or you’re in need of new parts, handling this issue in a timely manner will avoid additional problems and will enable you to address the issue before you have a heater outage.
