When your furnace is running properly, it should give warm air without creating too much disruption. While it’s normal to notice your furnace making noise as it begins running, other disruptions are showing your furnace should get immediate professional help.

Here are some of the most reported furnace noises and what they can be signaling. If your furnace is making an odd noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Austin, Texas.

1. Furnace Makes a Banging Sound

You might 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 may indicate there could be a couple of problems. These include 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 book annual furnace maintenance with Country Thyme AC & Home Services. One of the tasks our technicians do during this work is clean your furnace’s burners. When this part gets dirty, you could hear your furnace making a loud rumbling noise after ignition takes longer than normal. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can leak carbon monoxide, which is ordinarily released away from your home. This toxic gas can be lethal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Country Thyme AC & Home Services urges you to turn it off and contacting us at 512-954-2223. Significant natural gas in your furnace or a fractured heat exchanger are dangerous issues that require fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move heated air across your home. If the ductwork wasn’t put in right or is getting old, it can be loud when your furnace is heating. This can be the problem if your furnace makes a banging noise when it shuts off. Contact Country Thyme AC & Home Services at 512-954-2223 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you hear 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 depends on an internal transformer to operate 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 has a blower motor, which moves heated or cold air around your space, and a capacitor, which triggers the motor. If either of these components are failing, 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 related to something little, like an unsecure screw, or something major, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating professionals at 512-954-2223 for help.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to alert you it needs 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 lubricated. We know that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again rapidly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You could also be aware of whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still hearing sound, Country Thyme AC & Home Services can help. It’s critical to get loose ductwork repaired fast, since it can result in comfort troubles in your residence and drive up your utility bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise typically means there’s an issue with your furnace’s blower. Shut down your furnace off right away and call our professionals at 512-954-2223 for support.
