When your furnace is running properly, it should deliver warm air without making too much noise. While it’s common to hear your furnace making noise as it begins running, other disruptions are showing your furnace requires immediate professional assistance.

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

1. Furnace Makes a Banging Sound

You could have an urgent issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a couple of problems. These involve gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy over the years, so that’s why it’s essential to set annual furnace maintenance with North Mechanical Heating and Cooling. One of the jobs our pros perform during this service is clean your furnace’s burners. When this part gets dirty, you could hear your furnace making a loud rumbling noise after ignition is delayed. The ensuing gas buildup may crack your furnace’s heat exchanger, where natural gas turns into warm air. Any fractures in it can leak carbon monoxide, which is normally released away from your home. This toxic gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, North Mechanical Heating and Cooling urges you to turn it off and reaching us at 928-263-8570. Excessive natural gas in your furnace or a ruptured heat exchanger are serious problems that necessitate prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver hot air around your home. If the ductwork wasn’t put in correctly or is getting dated, it can be noisy when your furnace runs. This can be the problem if your furnace makes a banging noise when it shuts off. Call North Mechanical Heating and Cooling at 928-263-8570 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

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

Your furnace depends on an internal transformer to operate on the right voltage. If wires or the box is loose, you could hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves heated or cold air throughout your home, and a capacitor, which starts the motor. If either of these pieces are going out, they will buzz when the furnace starts.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it may be related to something little, like an unfastened screw, or something serious, like a broken part. In either case, we advise shutting your furnace off and getting in touch with our heating pros at 928-263-8570 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to get your attention it could use some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing might need to be greased. We are aware that maintenance frequently slips your mind, but our pros can get your furnace running quietly again fast.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You may also be aware of whistling while the furnace is running if a floor vent is loose. If you’ve looked at your vents but are still sensing noise, North Mechanical Heating and Cooling can help. It’s critical to get loose ductwork taken care of fast, as it can result in comfort troubles in your house and drive up your gas costs.

6. Furnace Making a Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal racket often means there’s an issue with your furnace’s blower. Turn off your furnace off right away and call our professionals at 928-263-8570 for support.
