Here are some of the most frequent furnace noises and what they could be signaling. If your furnace is making a strange noise, our friendly heating specialists are here to assist with the best furnace repair in Norton, Virginia.
1. Furnace Making a Banging Noise
You may have an urgent situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These involve gas accumulating in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy over time, so that’s why it’s essential to book yearly furnace maintenance with HCE Systems. One of the things our technicians perform during this service is clean your furnace’s burners. When this component gets dirty, you may hear your furnace making a loud rumbling noise if ignition is delayed. The following gas buildup might break your furnace’s heat exchanger, where natural gas transforms into warm air. Any fractures in it can emit carbon monoxide, which is normally released outdoors. This hazardous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, HCE Systems recommends turning it off and contacting us at 276-302-0076. Too much natural gas in your furnace or a broken heat exchanger are hazardous troubles that necessitate fast service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver warm air throughout your residence. If the ductwork wasn’t installed right or is aging, it can be loud when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Contact HCE Systems at 276-302-0076 and we’ll figure out 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 frequently indicates an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends heated or cooled air across your residence, and a capacitor, which starts the motor. If either of these pieces 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 could be due to something minor, like a loose screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating professionals at 276-302-0076 for assistance.
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 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 lubricated. We are aware that maintenance often slips your mind, but our techs can get your furnace operating quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re noticing your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You might also hear whistling while the furnace is running if a floor vent is loose. If you’ve checked your vents but are still hearing sound, HCE Systems can provide support. It’s important to get loose ductwork fixed fast, as it can make comfort troubles in your residence and drive up your heating bills.
6. Furnace Making a Grinding Noise
It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal sound often means there’s an issue with your furnace’s blower. Switch off your furnace off right away and call our professionals at 276-302-0076 for support.
