When your furnace is running properly, it should deliver heat without making too much noise. While it’s expected to hear your furnace making noise as it starts up, other noises are showing your furnace should get immediate professional help.
Here are some of the most common furnace noises and what they can be signaling. If your furnace is making a strange noise, our friendly heating specialists are here to help with the best furnace repair in Auburn, California.
1. Furnace Makes Banging or Knocking Sounds
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 may mean there could be a few problems. These involve gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy as time passes, so that’s why it’s critical to schedule annual furnace maintenance with Forster Heating. One of the things our technicians do during this appointment is clean your furnace’s burners. When this piece gets dirty, you could hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup can break your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can emit carbon monoxide, which is normally emitted away from your home. This hazardous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Forster Heating recommends turning it off and contacting us at 530-885-8081. Excessive natural gas in your furnace or a ruptured heat exchanger are hazardous problems that necessitate fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide warm air across your house. If the ductwork wasn’t installed correctly or is aging, it can make a lot of noise when your furnace is heating. This could be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Forster Heating at 530-885-8081 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you observe 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 uses an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you may notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends hot or cooled air throughout your space, and a capacitor, which triggers the motor. If either of these components are fading, they will buzz when the furnace switches on.
3. Furnace Rattles
If your furnace is making a rattling noise, it can be due to something little, like an unfastened screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating professionals at 530-885-8081 for support.
4. Furnace Is Making a High-Pitched Squealing Sound
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 forgotten furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubed. We realize that maintenance sometimes slips your mind, but our professionals can get your furnace heating quietly again rapidly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re detecting your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You may also notice whistling while the furnace is on if a floor vent isn’t tight. If you’ve looked at your vents but are still hearing sound, Forster Heating can provide support. It’s essential to get loose ductwork taken care of fast, as it can make comfort issues in your residence and drive up your utility expenses.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket usually means there’s trouble with your furnace’s blower. Switch off your furnace off instantly and reach us at 530-885-8081 for support.
