When your furnace is working like it should, it should deliver warm air without making too much disruption. While it’s expected to notice your furnace making noise as it begins running, other disruptions are signaling your furnace should get immediate professional help.
Here are some of the most common furnace noises and what they could mean. If your furnace is making a strange noise, our friendly heating pros are here to fix the problem with the best furnace repair in Newark, Ohio.
1. Furnace Making a Banging Noise
You might have an urgent situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a few problems. These range from gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy as time passes, so that’s why it’s critical to book annual furnace maintenance with Luikart Heating & Cooling. One of the things our professionals do during this service is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The ensuing gas buildup can crack your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can discharge carbon monoxide, which is normally vented outdoors. This dangerous gas can be deadly in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Luikart Heating & Cooling urges you to turn it off and contacting us at 740-344-5497. Excessive natural gas in your furnace or a cracked heat exchanger are hazardous problems that should get prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver hot air around your residence. If the ductwork wasn’t installed properly or is aging, it can be noisy when your furnace is heating. This may be the problem if your furnace makes a banging noise when it shuts off. Call Luikart Heating & Cooling at 740-344-5497 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the right voltage. If wires or the box needs to be tightened, you might notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or chilly air around your rooms, and a capacitor, which triggers the motor. If either of these parts are fading, 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 due to something little, like a loose screw, or something serious, like a broken component. In either case, we advise shutting your furnace off and contacting our heating pros at 740-344-5497 for support.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to get your attention it could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be lubricated. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace running quietly again rapidly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re detecting your furnace making a whistling noise, it’s likely due to 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 examined your vents but are still hearing whistling, Luikart Heating & Cooling can assist you. It’s critical to get loose ductwork repaired quickly, since it can result in comfort issues in your residence and drive up your utility bills.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal racket frequently means there’s a problem with your furnace’s blower. Switch off your furnace off now and reach our professionals at 740-344-5497 for support.
