When your furnace is working like it should, it should provide warmth without generating too much noise. While it’s common to catch your furnace making noise as it begins running, other noises are indicating your furnace needs immediate professional assistance.
Here are some of the most frequent furnace noises and what they can be signaling. If your furnace is making a weird noise, our friendly heating specialists are here to help with the best furnace repair in Cottonwood & Prescott, Arizona.
1. Furnace Making a Banging Noise
You may have a critical problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be several problems. These include gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty over the years, so that’s why it’s critical to set routine furnace maintenance with Connolly Electric & Mechanical. One of the things our techs complete during this work is clean your furnace’s burners. When this part gets grimy, you may hear your furnace making a loud rumbling noise if ignition is delayed. The subsequent gas buildup can fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any fractures in it can leak carbon monoxide, which is normally emitted away from your home. This dangerous gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Connolly Electric & Mechanical recommends turning it off and contacting us at 928-251-4327. Too much natural gas in your furnace or a ruptured heat exchanger are hazardous problems that necessitate prompt attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver heated air around your residence. If the ductwork wasn’t put in properly or is aging, it can make a lot of noise when your furnace is on. This may be the case if your furnace makes a banging noise when it shuts off. Get in touch with Connolly Electric & Mechanical at 928-251-4327 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently means there’s an electrical situation, 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 may notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends hot or chilly air throughout your space, and a capacitor, which turns on the motor. If either of these parts are failing, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be due to something small, like a loose screw, or something major, like a broken part. In either case, we advise shutting your furnace off and contacting our heating specialists at 928-251-4327 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to tell you it could use some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubricated. We are aware that maintenance sometimes slips your mind, but our pros can get your furnace running quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You could also hear whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still hearing sound, Connolly Electric & Mechanical can help. It’s essential to get loose ductwork taken care of without delay, because it can create comfort problems in your home and drive up your utility bills.
6. Furnace Making a Grinding Noise
It’s not an encouraging 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 contact our pros at 928-251-4327 for support.
