When your furnace is running correctly, it should give heat without generating too much disruption. While it’s expected to notice your furnace making noise as it turns on, other noises are indicating your furnace needs immediate professional support.

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

1. Furnace Makes Banging or Knocking Sounds

You may have an urgent problem 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 a few problems. These involve gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over time, so that’s why it’s essential to set yearly furnace maintenance with I-Deal HVAC. One of the jobs our pros do during this service is clean your furnace’s burners. When this component gets grimy, you may hear your furnace making a loud rumbling noise after ignition is delayed. The resulting gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can discharge carbon monoxide, which is ordinarily vented outside. This hazardous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, I-Deal HVAC advises turning it off and calling us at 505-317-9598. Too much natural gas in your furnace or a ruptured heat exchanger are serious issues that necessitate fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver hot air across your residence. If the ductwork wasn’t designed right or is aging, it can be noisy when your furnace is heating. This can be the issue if your furnace makes a banging noise when it shuts off. Get in touch with I-Deal HVAC at 505-317-9598 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves hot or cold air throughout your rooms, and a capacitor, which turns on the motor. If either of these parts are fading, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it could be related to something minor, like a loose screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating professionals at 505-317-9598 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to get your attention it requires some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn down or a bearing could need to be greased. We know that maintenance often slips your mind, but our technicians can get your furnace running quietly again fast.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is running if a floor vent isn’t tight. If you’ve looked at your vents but are still sensing whistling, I-Deal HVAC can provide support. It’s essential to get loose ductwork fixed without delay, since it can make comfort troubles in your home and inflate your utility expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal sound often means there’s an issue with your furnace’s blower. Shut down your furnace off promptly and call our pros at 505-317-9598 for support.
