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

Here are some of the most frequent furnace noises and what they might be signaling. If your furnace is making a weird noise, our friendly heating professionals are here to help with the best furnace repair in Yukon, Oklahoma.

1. Furnace Makes Banging or Knocking Sounds

You may have an urgent issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a couple of problems. These range from gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy over time, so that’s why it’s important to set routine furnace maintenance with Comfort Concepts Heating & Air Conditioning. One of the tasks our professionals complete during this service is clean your furnace’s burners. When this part gets grubby, you may hear your furnace making a loud rumbling noise after ignition is delayed. The following gas buildup can crack your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can discharge carbon monoxide, which is normally vented outdoors. This toxic gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Comfort Concepts Heating & Air Conditioning recommends turning it off and calling us at 405-494-7444. Too much natural gas in your furnace or a fractured heat exchanger are dangerous problems that should get immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver warm air throughout your home. If the ductwork wasn’t put in right or is aging, it can be noisy when your furnace runs. This can be the problem if your furnace makes a banging noise when it shuts off. Contact Comfort Concepts Heating & Air Conditioning at 405-494-7444 and we’ll pinpoint the problem.

2. Furnace Makes a Buzzing Sound

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often indicates an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work on the right voltage. If wires or the box needs to be tightened, you might detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or cold air across your home, and a capacitor, which turns on the motor. If either of these pieces are going out, they will buzz when the furnace switches on.

3. Furnace Rattles

If your furnace is making a rattling noise, it may be the result of something minor, like an unfastened screw, or something major, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating professionals at 405-494-7444 for support.

4. Furnace Making a Squealing Noise

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

5. Furnace Whistles

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 hear whistling while the furnace is operating if a floor vent is loose. If you’ve looked at your vents but are still sensing sound, Comfort Concepts Heating & Air Conditioning can provide support. It’s essential to get loose ductwork taken care of without delay, as it can make comfort issues in your residence and drive up your gas bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket frequently means there’s a problem with your furnace’s blower. Switch off your furnace off immediately and call our professionals at 405-494-7444 for support.
