When your furnace is operating properly, it should deliver heat without making too much sound. While it’s common to catch your furnace making noise as it begins running, other sounds are showing your furnace requires immediate professional support.
Here are some of the most frequent furnace noises and what they can be indicating. If your furnace is making an odd noise, our friendly heating specialists are here to assist with the best furnace repair in Branchville, New Jersey.
1. Furnace Making a Banging Noise
You might have a critical situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a few problems. These involve gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy over the years, so that’s why it’s essential to schedule yearly furnace maintenance with Willco Air Conditioning, Refrigeration & Heating Inc.. One of the things our pros perform during this appointment is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise after ignition is delayed. The ensuing gas buildup can break your furnace’s heat exchanger, where natural gas changes into heat. Any fractures in it can leak carbon monoxide, which is ordinarily vented away from your home. This toxic gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Willco Air Conditioning, Refrigeration & Heating Inc. recommends turning it off and reaching us at 862-345-6896. Significant natural gas in your furnace or a cracked heat exchanger are serious troubles that require prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver warm air around your home. If the ductwork wasn’t designed correctly or is getting old, it can make a lot of noise when your furnace is heating. This might be the case if your furnace makes a banging noise when it shuts off. Contact Willco Air Conditioning, Refrigeration & Heating Inc. at 862-345-6896 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually indicates an electrical problem, 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 needs to be tightened, you may notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or cold air around your space, and a capacitor, which turns on the motor. If either of these pieces are going out, they will buzz when the furnace turns on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be related to something minor, like an unfastened screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and calling our heating specialists at 862-345-6896 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 alert you it could use some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing may need to be greased. We are aware that maintenance often slips your mind, but our techs can get your furnace operating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also hear whistling while the furnace is running if a floor vent isn’t tight. If you’ve looked at your vents but are still sensing whistling, Willco Air Conditioning, Refrigeration & Heating Inc. can provide support. It’s critical to get loose ductwork fixed fast, since it can make comfort troubles in your house and inflate your heating expenses.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal noise often means there’s trouble with your furnace’s blower. Shut down your furnace off promptly and call our professionals at 862-345-6896 for support.
