When your furnace is operating like it should, it should give warmth without making too much disruption. While it’s expected to notice your furnace making noise as it turns on, other disruptions are indicating your furnace should get immediate professional assistance.

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

1. Furnace Making a Banging Noise

You might have an urgent problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a few problems. These involve gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy as time passes, so that’s why it’s important to schedule yearly furnace maintenance with Dial One Mears Air Conditioning & Heating Inc. One of the things our professionals perform during this service is clean your furnace’s burners. When this part gets dirty, you might hear your furnace making a loud rumbling noise when ignition takes more time. The following gas buildup may break your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can emit carbon monoxide, which is regularly vented outdoors. This hazardous gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Dial One Mears Air Conditioning & Heating Inc recommends turning it off and contacting us at 602-789-3315. Too much natural gas in your furnace or a fractured heat exchanger are serious troubles that necessitate prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide heated air throughout your home. If the ductwork wasn’t designed right or is getting dated, it can be loud when your furnace runs. This could be the problem 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 pinpoint the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically indicates an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the proper voltage. If wires or the box is loose, you may detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends warm or chilly air throughout your rooms, and a capacitor, which turns on the motor. If either of these components are fading, 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 related to something small, like a loose screw, or something major, like a broken component. In either case, we urge you to shut your furnace off and contacting our heating pros at 602-789-3315 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 alert you it requires some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubed. We realize that maintenance often slips your mind, but our techs can get your furnace heating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is on if a floor vent isn’t tight. If you’ve checked your vents but are still hearing noise, Dial One Mears Air Conditioning & Heating Inc can provide support. It’s critical to get loose ductwork fixed fast, because it can create comfort problems in your residence and inflate your gas expenses.

6. Furnace Making a Grinding Noise

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal sound often means there’s an issue with your furnace’s blower. Shut down your furnace off right away and contact our professionals at 602-789-3315 for assistance.
