When your furnace is operating like it should, it should provide warmth without generating too much noise. While it’s common to notice your furnace making noise as it begins running, other sounds are indicating your furnace needs immediate professional help.
Here are some of the most common furnace noises and what they might be signaling. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in Georgetown, Texas.
1. Furnace Making a Banging Noise
You may have an urgent issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a few problems. These range from gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over the years, so that’s why it’s essential to schedule routine furnace maintenance with Miller Climate Control LLC. One of the things our techs do during this appointment is clean your furnace’s burners. When this component gets grubby, you might hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup can break your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can discharge carbon monoxide, which is regularly emitted outside. This dangerous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Miller Climate Control LLC advises turning it off and reaching us at 512-937-2001. Too much natural gas in your furnace or a cracked heat exchanger are serious problems that require fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver warm air throughout your residence. If the ductwork wasn’t installed right or is getting dated, it can make a lot of noise when your furnace runs. This might be the case if your furnace makes a banging noise when it shuts off. Get in touch with Miller Climate Control LLC at 512-937-2001 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 often indicates an electrical issue, 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 isn’t tight enough, you might detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or cooled air across your home, and a capacitor, which triggers the motor. If either of these parts are going out, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be the result of something small, like a loose screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating specialists at 512-937-2001 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to alert you it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be greased. We know that maintenance sometimes slips your mind, but our pros can get your furnace heating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also notice whistling while the furnace is working if a floor vent isn’t secure. If you’ve checked your vents but are still sensing whistling, Miller Climate Control LLC can assist you. It’s essential to get loose ductwork taken care of quickly, as it can create comfort issues in your house and inflate your utility costs.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal racket frequently means there’s a problem with your furnace’s blower. Switch off your furnace off immediately and reach our professionals at 512-937-2001 for support.
