Here are some of the most frequent furnace noises and what they can mean. If your furnace is making an odd noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Eastland, TX.
1. Furnace Making a Banging Noise
You could have a serious situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a few problems. These include gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy as time passes, so that’s why it’s essential to schedule seasonal furnace maintenance with J & J Air Conditioning. One of the things our professionals complete during this appointment is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise after ignition takes more time. The following gas buildup can crack your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can discharge carbon monoxide, which is normally released outside. This dangerous gas can be lethal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, J & J Air Conditioning advises turning it off and calling us at 254-355-3833. Excessive natural gas in your furnace or a fractured heat exchanger are hazardous issues that require prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver warm air around your house. If the ductwork wasn’t installed right or is getting dated, it can be noisy when your furnace is on. This might be the issue if your furnace makes a banging noise when it shuts off. Call J & J Air Conditioning at 254-355-3833 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to work on the proper voltage. If wires or the box needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends hot or cooled air throughout your rooms, and a capacitor, which starts the motor. If either of these components are fading, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be related to something small, like a loose screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and calling our heating professionals at 254-355-3833 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to get your attention it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing may need to be lubricated. We realize that maintenance frequently slips your mind, but our technicians can get your furnace heating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You may also be aware of whistling while the furnace is running if a floor vent isn’t secure. If you’ve examined your vents but are still hearing noise, J & J Air Conditioning can assist you. It’s critical to get loose ductwork taken care of fast, because it can make comfort issues in your house and drive up your energy expenses.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal sound usually means there’s an issue with your furnace’s blower. Switch off your furnace off instantly and call us at 254-355-3833 for assistance.
