When your furnace is working correctly, it should give warmth without creating too much sound. While it’s expected to notice your furnace making noise as it starts up, other sounds are signaling your furnace needs immediate professional support.

Here are some of the most reported furnace noises and what they can be indicating. If your furnace is making an atypical noise, our friendly heating pros are here to help with the best furnace repair in Albuquerque, New Mexico.

1. Furnace Making a Banging Noise

You might have a serious problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These range from gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over the years, so that’s why it’s important to book annual furnace maintenance with Tru Air Systems LLC. One of the jobs our technicians complete during this service is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise if ignition is delayed. The resulting gas buildup can break your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can leak carbon monoxide, which is normally emitted outside. This hazardous gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Tru Air Systems LLC recommends turning it off and contacting us at 505-226-3525. Excessive natural gas in your furnace or a cracked heat exchanger are hazardous troubles that require prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move hot air across your house. If the ductwork wasn’t installed right or is getting dated, it can be noisy when your furnace is heating. This could be the case if your furnace makes a banging noise when it shuts off. Contact Tru Air Systems LLC at 505-226-3525 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually indicates an electrical situation, 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 is loose, you could notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or cold air throughout your residence, and a capacitor, which turns on the motor. If either of these pieces are going out, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be related to something small, like an unfastened screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and calling our heating specialists at 505-226-3525 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to tell you it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing could need to be greased. We know that maintenance frequently slips your mind, but our techs can get your furnace heating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also notice whistling while the furnace is on if a floor vent is loose. If you’ve examined your vents but are still hearing sound, Tru Air Systems LLC can assist you. It’s critical to get loose ductwork taken care of without delay, as it can make comfort problems in your residence and drive up your utility expenses.

6. Furnace Making a Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket often means there’s a problem with your furnace’s blower. Switch off your furnace off immediately and contact our professionals at 505-226-3525 for support.
