When your furnace is working properly, it should deliver warmth without making too much sound. While it’s expected to notice your furnace making noise as it begins running, other noises are signaling your furnace needs immediate professional assistance.

Here are some of the most reported furnace noises and what they might 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 Alliance, Nebraska.

1. Furnace Makes a Banging Sound

You could have a serious issue 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 several problems. These involve gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty as time passes, so that’s why it’s critical to schedule annual furnace maintenance with Jack's Heating, Cooling, Stoves & Fireplaces. One of the things our pros perform during this service is clean your furnace’s burners. When this piece gets dirty, you could hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup may fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can discharge carbon monoxide, which is normally emitted outdoors. This hazardous gas can be lethal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Jack's Heating, Cooling, Stoves & Fireplaces advises turning it off and calling us at 308-762-1613. Significant natural gas in your furnace or a broken heat exchanger are critical issues that require fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move warm air across your residence. If the ductwork wasn’t designed properly or is getting old, it can make a lot of noise when your furnace runs. This may be the problem if your furnace makes a banging noise when it shuts off. Contact Jack's Heating, Cooling, Stoves & Fireplaces at 308-762-1613 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually means there’s an electrical issue, 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 is loose, you may detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes heated or chilly air across your home, and a capacitor, which triggers the motor. If either of these components are fading, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be due to something little, like a loose screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating specialists at 308-762-1613 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to alert you it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing might need to be lubricated. We realize that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again quickly.

5. Furnace Whistles

When you’re noticing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You might also notice whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still hearing noise, Jack's Heating, Cooling, Stoves & Fireplaces can help. It’s important to get loose ductwork fixed without delay, since it can create comfort issues in your home and increase your utility costs.

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 frequently means there’s an issue with your furnace’s blower. Turn off your furnace off instantly and call us at 308-762-1613 for support.
