When your furnace is working properly, it should provide heat without creating too much sound. While it’s expected to notice your furnace making noise as it starts up, other disruptions are signaling your furnace should get immediate professional assistance.
Here are some of the most frequent furnace noises and what they might be indicating. If your furnace is making a weird noise, our friendly heating pros are here to help with the best furnace repair in Middletown.
1. Furnace Making a Banging Noise
You may 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 can signal there could be a few problems. These involve gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy over time, so that’s why it’s critical to book yearly furnace maintenance with SchagrinGAS Company. One of the tasks our techs do during this appointment is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise after ignition takes more time. The ensuing gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can leak carbon monoxide, which is normally vented outdoors. This toxic gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, SchagrinGAS Company advises turning it off and reaching us at 302-231-1380. Excessive natural gas in your furnace or a ruptured heat exchanger are hazardous problems that should get fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver warm air around your home. If the ductwork wasn’t installed correctly or is aging, it can make a lot of noise when your furnace runs. This can be the case if your furnace makes a banging noise when it shuts off. Contact SchagrinGAS Company at 302-231-1380 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound typically is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the correct voltage. If wires or the box needs to be tightened, you might hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes warm or chilly air across your residence, and a capacitor, which starts the motor. If either of these components 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 due to something small, like an unsecure screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and getting in touch with our heating pros at 302-231-1380 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to alert you it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing could need to be lubricated. We know that maintenance frequently slips your mind, but our professionals can get your furnace operating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You may also hear whistling while the furnace is working if a floor vent is loose. If you’ve checked your vents but are still sensing sound, SchagrinGAS Company can help. It’s important to get loose ductwork repaired without delay, as it can create comfort troubles in your residence and inflate your heating costs.
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 typically means there’s a problem with your furnace’s blower. Turn off your furnace off right away and contact our professionals at 302-231-1380 for support.
