When your furnace is running like it should, it should provide heat without generating too much noise. While it’s expected to notice your furnace making noise as it begins running, other disruptions are indicating your furnace should get immediate professional help.
Here are some of the most common furnace noises and what they might be signaling. If your furnace is making a strange noise, our friendly heating specialists are here to help with the best furnace repair in Derby, Connecticut.
1. Furnace Making a Banging Noise
You might have a critical 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 a couple of problems. These involve gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system becomes dirty over time, so that’s why it’s critical to set yearly furnace maintenance with Giordanos Heating and Air Conditioning. One of the things our professionals do during this service is clean your furnace’s burners. When this component gets grubby, you might hear your furnace making a loud rumbling noise when ignition takes more time. The subsequent gas buildup can break your furnace’s heat exchanger, where natural gas transforms into warmth. Any fractures in it can leak carbon monoxide, which is regularly released outside. This dangerous gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Giordanos Heating and Air Conditioning urges you to turn it off and calling us at 203-772-8319. Significant natural gas in your furnace or a broken heat exchanger are serious problems that necessitate prompt repairs.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to provide heated air around your home. If the ductwork wasn’t put in right or is getting dated, it can be noisy when your furnace is heating. This can be the issue if your furnace makes a banging noise when it shuts off. Call Giordanos Heating and Air Conditioning at 203-772-8319 and we’ll determine the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically means there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to work on the proper voltage. If wires or the box needs to be tightened, you could notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends hot or cooled air around your space, and a capacitor, which triggers 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 can be due to something small, like an unsecure screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and calling our heating professionals at 203-772-8319 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to get your attention it requires some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be lubed. We know that maintenance frequently slips your mind, but our techs can get your furnace heating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re hearing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You may also be aware of whistling while the furnace is running if a floor vent isn’t tight. If you’ve looked at your vents but are still hearing whistling, Giordanos Heating and Air Conditioning can assist you. It’s essential to get loose ductwork repaired quickly, because it can result in comfort troubles in your home 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 sound often means there’s a problem with your furnace’s blower. Turn off your furnace off right away and contact our pros at 203-772-8319 for support.
