When your furnace is running properly, it should provide warmth without making too much noise. While it’s normal to catch your furnace making noise as it begins running, other disruptions are showing your furnace needs immediate professional support.

Here are some of the most common furnace noises and what they could be indicating. If your furnace is making an odd noise, our friendly heating professionals are here to assist with the best furnace repair in Phoenix, Arizona.

1. Furnace Making a Banging Noise

You could have an urgent situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a couple of problems. These include gas increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy as time passes, so that’s why it’s important to schedule routine furnace maintenance with Dial One Mears Air Conditioning & Heating Inc. One of the tasks our technicians perform during this work is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise if ignition takes longer than normal. The subsequent gas buildup can fracture your furnace’s heat exchanger, where natural gas turns into heat. Any fractures in it can leak carbon monoxide, which is ordinarily released away from your home. This toxic gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Dial One Mears Air Conditioning & Heating Inc urges you to turn it off and reaching us at 602-789-3315. Significant natural gas in your furnace or a broken heat exchanger are serious issues that necessitate immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move heated air around your house. If the ductwork wasn’t installed correctly or is getting old, it can be noisy when your furnace runs. This could be the case if your furnace makes a banging noise when it shuts off. Contact Dial One Mears Air Conditioning & Heating Inc at 602-789-3315 and we’ll determine the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically 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 needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or cold air across your rooms, and a capacitor, which triggers the motor. If either of these pieces are going out, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be due to something small, like a loose screw, or something critical, like a broken piece. In either case, we recommend shutting off your furnace and getting in touch with our heating pros at 602-789-3315 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to tell you it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubricated. We realize that maintenance sometimes slips your mind, but our professionals can get your furnace heating quietly again rapidly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You might also notice whistling while the furnace is running if a floor vent isn’t secure. If you’ve looked at your vents but are still hearing noise, Dial One Mears Air Conditioning & Heating Inc can help. It’s essential to get loose ductwork taken care of fast, since it can create comfort troubles in your house and increase your heating expenses.

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 noise usually means there’s trouble with your furnace’s blower. Shut down your furnace off right away and reach our professionals at 602-789-3315 for help.
