What is Causing Those Heater System Noises Inside Your Home?

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


Banging sounds are often caused by dirty burners. If your furnace’s burners are not regularly cleaned, dirt will build up around the burners. If this isn’t addressed, it can cause a delay in the ignition of the gas that goes into your system.

This delay can lead to a buildup of gas and a small explosion when ignition finally does take place. Obviously, this can be dangerous and can damage your heater.

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.

Scraping Sounds


A scraping sound or the sound of metal on metal can be caused by a few things including a loose blower wheel, a broken blower wheel, or a broken motor mount. If not addressed, these issues can cause additional problems to your unit.

If you hear a scraping sound, it’s a good idea to turn off your heater and call a professional. Don’t run the furnace again until it’s been inspected and repaired to avoid a more serious problem. Hopefully, these tips will help you determine the cause of heater noises.

If you’re hearing an unusual noise from your furnace or concerned about how it’s functioning, it’s always a good idea to contact an HVAC professional. Addressing furnace issues as soon as possible can help to minimize any damage and to avoid an HVAC emergency.

“Five stars--could not be happier!  Josh and Kyle were very professional, provided several options to improve performance of HVAC, no pressure or time constraints, worked efficiently, were able to explain in clear terms what they found, including when items were performing in fine fashion and nothing needed to be done.  Thanks for a happy camper”


“Service was outstanding from the time of arrival which you could track arrival time live on a website link they send you so you know when they will arrive. Technical knowledge was very high, quick and efficient Kyle and his partner both handled the install of a Sensi Predict as if it was a walk in the park. I highly recommend Kyle from Nice Heating & Air for all HVAC issues and for new installs, him and his team are an amazing company and will think of them first if any issues arise in the future for sure....”

Andrew Baker.

“Professional and polite. Excellent communication throughout the maintenance visit. Definitely recommend.”


“Rolando Medrano was very professional and followed the CDC protocol of 6 feet social distance and had a mask and put disposable shoe covers before entering the house. He made sure to address all of our issues and provided answers for all our questions. He came on time and called before he came to update on timing and his status! He was a great help!”

Mike Richardson.

“Highly recommend Nice Home Services for your HVAC needs. Have been member of their annual maintenance plan for three years now and been extremely pleased with their approach to business. They are professional, knowledgeable, and relatable. The service specialists take their time to fully diagnose the issue and explain the situation in a way that is easy to understand. Never had an instance where they try to push product and instead look for ways to recommend how to save you money. Need anything done on your home's HVAC, call the folks at Nice Home Services and know you're making the right choice.”

Richard Nowinski.

“Dionte and his helper (Josh) did a superb job with the installation. The result is both functional and as cosmetically pleasing as the ideal water heater installation can be. They were VERY careful moving the old one out and the new one in so as to assure no damage was initiated neither to the heater nor to our dwelling. He explained his intended design prior to execution and executed it flawlessly. This was followed by a comprehensive explanation of the functional options available through the control panel and Ipad app. Cleanup at conclusion of the install was appropriate and comprehensive. This team represented both Nice Heating and Rheem VERY positively!”

Kimberly Mason.

“I purchased my HVAC unit a year ago along with a Cozy Club maintenance plan. It's been running great and the customer service team is always quick to respond to questions.

I'm very happy with my experience with Nice.”

N. England.

“I can't speak highly enough of this company. I requested an appointment, and it was scheduled for the next day. The technician was polite, honest, and a pure delight to work with. He didn't try to overcharge or tell me to replace something I didn't need to. He made service recommendations that were in line with industry standard prices so I could make an informed decision as he went about his service visit. Would recommend and will be using them again in the future. ”
