When your furnace is operating properly, it should deliver warmth without making too much noise. While it’s expected to hear your furnace making noise as it starts up, other noises are indicating your furnace needs immediate professional support.
Here are some of the most reported furnace noises and what they might be indicating. If your furnace is making an odd noise, our friendly heating pros are here to assist with the best furnace repair in Alice, Texas.
1. Furnace Making a Banging Noise
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 might indicate there could be a few problems. These involve gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty as time passes, so that’s why it’s important to set annual furnace maintenance with Rescue Heating & Air. One of the tasks our techs do during this work is clean your furnace’s burners. When this component gets dirty, you may hear your furnace making a loud rumbling noise when ignition is delayed. The subsequent gas buildup may break your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can emit carbon monoxide, which is ordinarily vented away from your home. This dangerous gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Rescue Heating & Air urges you to turn it off and contacting us at 361-265-4371. Significant natural gas in your furnace or a ruptured heat exchanger are hazardous problems that require immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver hot air across your house. If the ductwork wasn’t put in properly or is aging, it can make a lot of noise when your furnace is heating. This can be the issue if your furnace makes a banging noise when it shuts off. Contact Rescue Heating & Air at 361-265-4371 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically indicates an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to run on the proper voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes hot or cooled air across your rooms, and a capacitor, which triggers the motor. If either of these parts are going out, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be due to something little, like an unsecure screw, or something critical, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating pros at 361-265-4371 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to tell you it needs some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be lubricated. We realize that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also notice whistling while the furnace is working if a floor vent isn’t secure. If you’ve examined your vents but are still sensing sound, Rescue Heating & Air can assist you. It’s important to get loose ductwork repaired quickly, because it can result in comfort issues in your residence and inflate your heating expenses.
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 a problem with your furnace’s blower. Turn off your furnace off right away and contact us at 361-265-4371 for help.
