When your furnace is running like it should, it should give heat without generating too much noise. While it’s normal to hear your furnace making noise as it begins running, other noises are indicating your furnace requires immediate professional support.

Here are some of the most common furnace noises and what they could mean. If your furnace is making an atypical noise, our friendly heating specialists are here to assist with the best furnace repair in Macon, Georgia.

1. Furnace Making a Banging Noise

You may have a serious problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a couple of problems. These involve gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy over the years, so that’s why it’s essential to book annual furnace maintenance with Air Temperature Control. One of the jobs our professionals complete during this appointment is clean your furnace’s burners. When this part gets grubby, you might hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup might crack your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can discharge carbon monoxide, which is ordinarily emitted 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, Air Temperature Control recommends turning it off and reaching us at 478-202-3170. Excessive natural gas in your furnace or a fractured heat exchanger are dangerous troubles that necessitate immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move hot air around your home. If the ductwork wasn’t designed right or is getting dated, it can make a lot of noise when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Air Temperature Control at 478-202-3170 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

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

Your furnace uses an internal transformer to work on the proper voltage. If wires or the box is loose, you might hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes heated or cold air around your house, 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 minor, like an unsecure screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and getting in touch with our heating pros at 478-202-3170 for help.

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 get your attention it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing may need to be lubed. We know that maintenance often slips your mind, but our professionals can get your furnace operating quietly again quickly.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You could also hear whistling while the furnace is running if a floor vent is loose. If you’ve looked at your vents but are still noticing whistling, Air Temperature Control can provide support. It’s critical to get loose ductwork repaired without delay, because it can result in comfort problems in your residence and inflate your utility costs.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal noise often means there’s an issue with your furnace’s blower. Turn off your furnace off right away and reach our pros at 478-202-3170 for assistance.
