When your furnace is running correctly, it should give warmth without making too much disruption. While it’s common to hear your furnace making noise as it starts up, other sounds are indicating your furnace should get immediate professional support.
Here are some of the most frequent furnace noises and what they can 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 East Bernard, Texas.
1. Furnace Makes a Banging Sound
You could 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 several problems. These include gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets filthy over the years, so that’s why it’s important to schedule annual furnace maintenance with E.B. Air. One of the jobs our professionals perform during this appointment is clean your furnace’s burners. When this part gets dirty, you could hear your furnace making a loud rumbling noise after ignition is delayed. The ensuing gas buildup may break your furnace’s heat exchanger, where natural gas turns into warmth. Any cracks in it can leak carbon monoxide, which is ordinarily released away from your home. This dangerous gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, E.B. Air recommends turning it off and reaching us at 979-335-4262. Too much natural gas in your furnace or a cracked heat exchanger are hazardous issues that should get fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver warm air throughout your home. If the ductwork wasn’t designed right or is aging, it can make a lot of noise when your furnace runs. This may be the problem if your furnace makes a banging noise when it shuts off. Contact E.B. Air at 979-335-4262 and we’ll pinpoint the problem.
2. Furnace Buzzes Constantly
If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the correct voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or cooled air across your space, and a capacitor, which turns on the motor. If either of these components are fading, they will buzz when the furnace turns on.
3. Furnace Rattles
If your furnace is making a rattling noise, it may be the result of something little, like a loose screw, or something major, like a broken part. In either case, we recommend shutting off your furnace and getting in touch with our heating professionals at 979-335-4262 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to tell you it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing might need to be lubricated. We know that maintenance sometimes slips your mind, but our professionals can get your furnace running quietly again quickly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re noticing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You might also hear whistling while the furnace is operating if a floor vent isn’t secure. If you’ve examined your vents but are still noticing whistling, E.B. Air can assist you. It’s important to get loose ductwork taken care of quickly, as it can result in comfort troubles in your house and increase your gas 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 trouble with your furnace’s blower. Turn off your furnace off right away and reach us at 979-335-4262 for help.
