1. Furnace Making a Banging Noise

You could 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 signal there could be a few problems. These include gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over time, so that’s why it’s important to schedule annual furnace maintenance with Gee & Missler Heating & Air Conditioning. One of the jobs our techs do during this service is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise after ignition takes more time.

This hazardous gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Gee & Missler Heating & Air Conditioning advises turning it off and contacting us at 734-284-1224. Excessive natural gas in your furnace or a broken heat exchanger are hazardous troubles that should get prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide warm air across your home. If the ductwork wasn’t put in properly or is aging, it can be noisy when your furnace is heating. This can be the problem if your furnace makes a banging noise when it shuts off. Contact Gee & Missler Heating & Air Conditioning at 734-284-1224 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the correct voltage. If wires or the box is loose, you might hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or chilly air throughout your home, and a capacitor, which triggers the motor. If either of these pieces are failing, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be the result of something little, like an unsecure screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating specialists at 734-284-1224 for assistance.

If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be lubricated. We are aware that maintenance frequently slips your mind, but our techs can get your furnace running quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You could also notice whistling while the furnace is operating if a floor vent isn’t secure. If you’ve examined your vents but are still noticing whistling, Gee & Missler Heating & Air Conditioning can provide support. It’s essential to get loose ductwork repaired fast, because it can result in comfort problems in your residence and drive up your gas expenses.
