When your furnace is operating properly, it should deliver heat without creating too much disruption. While it’s normal to notice your furnace making noise as it begins running, other disruptions are indicating your furnace requires immediate professional support.

Here are some of the most common furnace noises and what they might be indicating. If your furnace is making an odd noise, our friendly heating pros are here to help with the best furnace repair in Wyandotte, Michigan .

1. Furnace Making a Banging Noise

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

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over the years, so that’s why it’s essential to schedule yearly furnace maintenance with Gee & Missler Heating & Air Conditioning. One of the jobs our pros complete during this work is clean your furnace’s burners. When this component gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup can break your furnace’s heat exchanger, where natural gas turns into warmth. Any cracks in it can discharge carbon monoxide, which is regularly released outside. This dangerous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Gee & Missler Heating & Air Conditioning advises turning it off and reaching us at 734-284-1224. Significant natural gas in your furnace or a fractured heat exchanger are critical problems that should get immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide heated air throughout your home. If the ductwork wasn’t put in right or is getting dated, it can be noisy when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Contact Gee & Missler Heating & Air Conditioning at 734-284-1224 and we’ll determine the problem.

2. Furnace Buzzes Constantly

If you notice 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 relies on an internal transformer to operate on the right voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes warm or cold air throughout your home, and a capacitor, which turns on the motor. If either of these components are going out, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it may be related to something small, 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 pros at 734-284-1224 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to alert you it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubed. We know that maintenance sometimes slips your mind, but our technicians can get your furnace heating quietly again fast.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You might also notice whistling while the furnace is operating if a floor vent isn’t tight. If you’ve checked your vents but are still hearing noise, Gee & Missler Heating & Air Conditioning can provide support. It’s important to get loose ductwork taken care of fast, since it can create comfort troubles in your home and increase your heating expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket frequently means there’s trouble with your furnace’s blower. Switch off your furnace off instantly and contact our professionals at 734-284-1224 for help.
