When your furnace is running correctly, it should provide warmth without generating too much sound. While it’s common to hear your furnace making noise as it turns on, other sounds are signaling your furnace requires immediate professional assistance.

Here are some of the most frequent furnace noises and what they can mean. If your furnace is making an odd noise, our friendly heating professionals are here to help with the best furnace repair in Cache Valley, Utah.

1. Furnace Makes Banging or Knocking Sounds

You might have a critical problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a couple of problems. These involve gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy as time passes, so that’s why it’s essential to schedule yearly furnace maintenance with Western Mechanical, Inc.. One of the jobs our professionals do during this service is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise when ignition takes longer than normal. The subsequent gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can emit carbon monoxide, which is regularly vented outside. This hazardous gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Western Mechanical, Inc. recommends turning it off and calling us at 435-753-5515. Too much natural gas in your furnace or a fractured heat exchanger are dangerous troubles that should get fast service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move warm air across your house. If the ductwork wasn’t designed correctly or is getting dated, it can be loud when your furnace is on. This might be the issue if your furnace makes a banging noise when it shuts off. Call Western Mechanical, Inc. at 435-753-5515 and we’ll pinpoint the problem.

2. Furnace Makes a Buzzing Sound

If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually means there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the correct voltage. If wires or the box is loose, you might hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cold air around your residence, and a capacitor, which turns on the motor. If either of these components are going out, they will buzz when the furnace switches on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it could be related to something small, like an unsecure screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and getting in touch with our heating specialists at 435-753-5515 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to alert you it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing may need to be lubricated. We are aware that maintenance often slips your mind, but our technicians can get your furnace operating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You might also hear whistling while the furnace is running if a floor vent isn’t tight. If you’ve looked at your vents but are still sensing whistling, Western Mechanical, Inc. can assist you. It’s essential to get loose ductwork fixed without delay, because it can make comfort issues in your home and inflate your heating bills.

6. Furnace Making a Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal sound usually means there’s an issue with your furnace’s blower. Turn off your furnace off instantly and reach our pros at 435-753-5515 for help.
