When your furnace is operating like it should, it should deliver warmth without creating too much sound. While it’s common to hear your furnace making noise as it turns on, other noises are indicating your furnace should get immediate professional help.

Here are some of the most frequent furnace noises and what they can be signaling. If your furnace is making an odd noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Alice, Texas.

1. Furnace Making a Banging Noise

You could 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 might indicate there could be a couple of problems. These range from gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty as time passes, so that’s why it’s critical to set seasonal furnace maintenance with Rescue Heating & Air. One of the jobs our technicians do during this service is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes longer than normal. The resulting gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into heat. Any breaks in it can discharge carbon monoxide, which is regularly released away from your home. This dangerous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Rescue Heating & Air urges you to turn it off and reaching us at 361-265-4371. Too much natural gas in your furnace or a cracked heat exchanger are dangerous issues that require immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move heated air throughout your home. If the ductwork wasn’t designed properly or is aging, it can make a lot of noise when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Call Rescue Heating & Air at 361-265-4371 and we’ll determine the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace uses an internal transformer to operate on the right voltage. If wires or the box isn’t tight enough, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes warm or cooled air around your home, and a capacitor, which starts the motor. If either of these pieces are failing, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be the result of something small, like an unsecure screw, or something serious, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating pros at 361-265-4371 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to alert you it needs some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing could need to be lubed. We are aware that maintenance sometimes slips your mind, but our technicians can get your furnace heating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You might also notice whistling while the furnace is on if a floor vent isn’t secure. If you’ve looked at your vents but are still hearing sound, Rescue Heating & Air can provide support. It’s critical to get loose ductwork repaired quickly, because it can create comfort problems in your residence and drive up your utility costs.

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 now and reach our professionals at 361-265-4371 for assistance.
