When your furnace is running correctly, it should deliver heat without generating too much sound. While it’s common to notice your furnace making noise as it turns on, other sounds are signaling your furnace should get immediate professional assistance.

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

1. Furnace Making a Banging Noise

You could have a critical situation on your hands if you’re hearing 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 building up in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy as time passes, so that’s why it’s critical to set annual furnace maintenance with JTech Mechanical. One of the things our professionals complete during this work is clean your furnace’s burners. When this piece gets dirty, you may hear your furnace making a loud rumbling noise if ignition is delayed. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into warm air. Any fractures in it can discharge carbon monoxide, which is ordinarily vented outside. This dangerous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, JTech Mechanical advises turning it off and contacting us at 281-231-8768. Significant natural gas in your furnace or a cracked heat exchanger are hazardous problems that necessitate prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move warm air across your house. If the ductwork wasn’t designed correctly or is getting dated, it can make a lot of noise when your furnace is on. This may be the problem if your furnace makes a banging noise when it shuts off. Get in touch with JTech Mechanical at 281-231-8768 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often means 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 is loose, you may detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or cold air across your house, and a capacitor, which turns on the motor. If either of these parts are failing, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be related to something minor, like a loose screw, or something major, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating specialists at 281-231-8768 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to tell you it needs some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing may need to be lubed. We are aware that maintenance often slips your mind, but our pros can get your furnace operating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You could also notice whistling while the furnace is working if a floor vent isn’t secure. If you’ve looked at your vents but are still noticing whistling, JTech Mechanical can help. It’s important to get loose ductwork taken care of without delay, since it can make comfort troubles in your residence and drive up your energy costs.

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 frequently means there’s an issue with your furnace’s blower. Turn off your furnace off promptly and reach our professionals at 281-231-8768 for support.
