When your furnace is operating properly, it should deliver warmth without creating too much sound. While it’s common to hear your furnace making noise as it begins running, other disruptions are indicating your furnace needs immediate professional assistance.
Here are some of the most common furnace noises and what they might be indicating. If your furnace is making an odd noise, our friendly heating professionals are here to assist with the best furnace repair in Freehold, New Jersey.
1. Furnace Makes a Banging Sound
You could have a critical situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be several problems. These involve gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy over time, so that’s why it’s essential to book annual furnace maintenance with Perfect Air & Water Services. One of the things our pros complete during this work is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise after ignition is delayed. The ensuing gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can leak carbon monoxide, which is normally vented outdoors. This dangerous gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Perfect Air & Water Services advises turning it off and calling us at 848-217-4183. Too much natural gas in your furnace or a cracked heat exchanger are serious issues that should get immediate repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to move hot air across your home. If the ductwork wasn’t designed properly or is getting dated, it can be noisy when your furnace is on. This can be the case if your furnace makes a banging noise when it shuts off. Call Perfect Air & Water Services at 848-217-4183 and we’ll pinpoint the problem.
2. Furnace Makes a Buzzing Sound
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the proper voltage. If wires or the box isn’t tight enough, you might hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends heated or cooled air around your rooms, and a capacitor, which triggers the motor. If either of these pieces are fading, they will buzz when the furnace starts.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it could be due to something little, like an unsecure screw, or something major, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating specialists at 848-217-4183 for help.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to alert you it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing may need to be lubed. We are aware that maintenance often slips your mind, but our pros can get your furnace running quietly again rapidly.
5. Furnace Whistles
When you’re noticing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You might also notice whistling while the furnace is working if a floor vent is loose. If you’ve checked your vents but are still noticing whistling, Perfect Air & Water Services can provide support. It’s important to get loose ductwork repaired without delay, as it can result in comfort problems in your home and increase your utility expenses.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket usually means there’s an issue with your furnace’s blower. Turn off your furnace off right away and reach our pros at 848-217-4183 for help.
