When your furnace is working properly, it should give heat without creating too much sound. While it’s normal to hear your furnace making noise as it starts up, other disruptions are showing your furnace should get immediate professional support.

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

1. Furnace Making a Banging Noise

You may have a serious situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a couple of problems. These range from gas building up in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over the years, so that’s why it’s critical to set annual furnace maintenance with Tru Air Systems LLC. One of the things our techs perform during this work is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can emit carbon monoxide, which is regularly emitted outside. This hazardous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Tru Air Systems LLC urges you to turn it off and calling us at 505-226-3525. Too much natural gas in your furnace or a ruptured heat exchanger are serious problems that should get fast service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver warm air across your home. If the ductwork wasn’t installed right or is getting old, it can make a lot of noise when your furnace is heating. This might be the problem if your furnace makes a banging noise when it shuts off. Call Tru Air Systems LLC at 505-226-3525 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 means there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the correct 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 works with a blower motor, which sends hot or cold air across your rooms, and a capacitor, which triggers the motor. If either of these parts are going out, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be due to something small, like an unsecure screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and contacting 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 on, it’s trying to alert you it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be lubricated. We realize that maintenance often slips your mind, but our techs can get your furnace heating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You might also notice whistling while the furnace is running if a floor vent is loose. If you’ve looked at your vents but are still hearing sound, Tru Air Systems LLC can help. It’s important to get loose ductwork repaired fast, since it can make comfort troubles in your residence and drive up your heating expenses.

6. Furnace Making a Grinding Noise

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal racket frequently means there’s a problem with your furnace’s blower. Shut down your furnace off instantly and call us at 505-226-3525 for assistance.
