When your furnace is running correctly, it should give warmth without making too much noise. While it’s normal to catch your furnace making noise as it starts up, other noises are signaling your furnace needs immediate professional assistance.
Here are some of the most common furnace noises and what they might be indicating. If your furnace is making a strange 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 issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a couple of problems. These range from gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over the years, so that’s why it’s critical to schedule yearly furnace maintenance with Western Mechanical, Inc.. One of the tasks our technicians do during this work is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise if ignition is delayed. The following gas buildup can break your furnace’s heat exchanger, where natural gas changes into warm air. Any fractures in it can emit carbon monoxide, which is regularly emitted away from your home. This hazardous gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Western Mechanical, Inc. advises turning it off and reaching us at 435-753-5515. Too much natural gas in your furnace or a fractured heat exchanger are critical issues that necessitate immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move warm air across your home. If the ductwork wasn’t designed properly or is getting dated, it can be loud when your furnace is heating. This might be the problem if your furnace makes a banging noise when it shuts off. Contact Western Mechanical, Inc. at 435-753-5515 and we’ll determine the problem.
2. Furnace Buzzes Constantly
If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to run on the proper voltage. If wires or the box isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends hot or cooled air across your house, and a capacitor, which triggers the motor. If either of these pieces are failing, 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 minor, like a loose screw, or something critical, like a broken component. In either case, we recommend shutting off your furnace and calling our heating professionals at 435-753-5515 for support.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to get your attention it needs some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing may need to be greased. We know that maintenance often slips your mind, but our professionals can get your furnace running quietly again rapidly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re noticing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent is loose. If you’ve examined your vents but are still hearing noise, Western Mechanical, Inc. can assist you. It’s critical to get loose ductwork repaired fast, because it can make comfort troubles in your residence and increase your utility bills.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound usually means there’s a problem with your furnace’s blower. Turn off your furnace off now and call our professionals at 435-753-5515 for support.
