When your furnace is running correctly, it should deliver heat without creating too much noise. While it’s expected to hear your furnace making noise as it turns on, other disruptions are indicating your furnace requires immediate professional support.

Here are some of the most reported furnace noises and what they could be indicating. If your furnace is making a weird noise, our friendly heating pros are here to fix the problem with the best furnace repair in Odessa, Texas.

1. Furnace Makes Banging or Knocking Sounds

You could have a critical situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be several problems. These involve gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over the years, so that’s why it’s essential to schedule yearly furnace maintenance with Redhawk Heating & Air Conditioning. One of the jobs our professionals perform during this appointment is clean your furnace’s burners. When this component gets dirty, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The subsequent gas buildup can crack your furnace’s heat exchanger, where natural gas turns into warmth. Any cracks in it can leak carbon monoxide, which is regularly vented outdoors. This hazardous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Redhawk Heating & Air Conditioning urges you to turn it off and calling us at 432-237-0168. Too much natural gas in your furnace or a ruptured heat exchanger are hazardous problems that require immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide hot air across your home. 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 case if your furnace makes a banging noise when it shuts off. Contact Redhawk Heating & Air Conditioning at 432-237-0168 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace uses an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or chilly air around your house, and a capacitor, which turns on the motor. If either of these pieces are going out, they will buzz when the furnace switches on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it may be due to something small, like an unsecure screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and calling our heating pros at 432-237-0168 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to get your attention it could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubed. We are aware that maintenance often slips your mind, but our techs can get your furnace heating quietly again fast.

5. Furnace Whistles

When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You could also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing whistling, Redhawk Heating & Air Conditioning can help. It’s critical to get loose ductwork taken care of without delay, because it can result in comfort issues in your house and drive up your heating costs.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal sound usually means there’s a problem with your furnace’s blower. Switch off your furnace off instantly and contact our professionals at 432-237-0168 for assistance.
