When your furnace is working correctly, it should give warmth without making too much sound. While it’s common to notice your furnace making noise as it turns on, other sounds are showing your furnace should get immediate professional assistance.

Here are some of the most reported furnace noises and what they can be signaling. If your furnace is making a weird noise, our friendly heating professionals are here to help with the best furnace repair in Cache Valley, Utah.

1. Furnace Making a Banging Noise

You might have a critical situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These include gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over the years, so that’s why it’s critical to set yearly furnace maintenance with Western Mechanical, Inc.. One of the things our pros complete during this appointment is clean your furnace’s burners. When this component gets grimy, you might hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into heat. Any cracks in it can emit carbon monoxide, which is normally vented away from your home. This toxic 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 broken heat exchanger are dangerous troubles that necessitate immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver warm air around your house. If the ductwork wasn’t put in correctly or is aging, it can be noisy when your furnace is heating. This can be the case if your furnace makes a banging noise when it shuts off. Get in touch with Western Mechanical, Inc. at 435-753-5515 and we’ll figure out 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 frequently indicates an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to work on the correct voltage. If wires or the box is loose, you may hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or cooled air throughout your house, and a capacitor, which triggers the motor. If either of these components are failing, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it could be the result of something small, like an unfastened screw, or something serious, like a broken component. In either case, we advise shutting your furnace off and calling our heating specialists at 435-753-5515 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to get your attention it needs some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubed. We know that maintenance sometimes slips your mind, but our techs can get your furnace operating quietly again fast.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also hear whistling while the furnace is running if a floor vent is loose. If you’ve looked at your vents but are still sensing whistling, Western Mechanical, Inc. can provide support. It’s important to get loose ductwork repaired without delay, because it can make comfort issues in your residence and increase your utility costs.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal sound usually means there’s an issue with your furnace’s blower. Shut down your furnace off right away and contact our professionals at 435-753-5515 for help.
