When your furnace is running like it should, it should deliver warm air without making too much sound. While it’s expected to catch your furnace making noise as it starts up, other noises are signaling your furnace requires immediate professional help.

Here are some of the most common furnace noises and what they can be indicating. If your furnace is making an atypical noise, our friendly heating specialists are here to help with the best furnace repair in Palm Coast, Florida.

1. Furnace Making a Banging Noise

You could have a serious issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a couple of problems. These range from gas accumulating 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 important to book annual furnace maintenance with Cooks Air Conditioning and Heating Specialists. One of the tasks our technicians complete during this appointment is clean your furnace’s burners. When this piece gets grimy, you could hear your furnace making a loud rumbling noise if ignition is delayed. The ensuing gas buildup can crack your furnace’s heat exchanger, where natural gas changes into warm air. Any fractures in it can leak carbon monoxide, which is normally emitted outside. This toxic gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Cooks Air Conditioning and Heating Specialists advises turning it off and reaching us at 386-313-8766. Too much natural gas in your furnace or a cracked heat exchanger are critical issues that necessitate prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move warm air around your residence. If the ductwork wasn’t put in correctly or is getting old, it can be noisy when your furnace runs. This might be the issue if your furnace makes a banging noise when it shuts off. Contact Cooks Air Conditioning and Heating Specialists at 386-313-8766 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to run on the proper voltage. If wires or the box needs to be tightened, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or chilly air around your house, and a capacitor, which turns on the motor. If either of these components are failing, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be related to something little, like an unfastened screw, or something serious, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating pros at 386-313-8766 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to alert you it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing may need to be lubed. We know that maintenance frequently slips your mind, but our pros can get your furnace heating quietly again rapidly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also notice whistling while the furnace is on if a floor vent isn’t secure. If you’ve checked your vents but are still hearing sound, Cooks Air Conditioning and Heating Specialists can help. It’s critical to get loose ductwork taken care of quickly, since it can create comfort troubles in your house and inflate your heating costs.

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 noise frequently means there’s a problem with your furnace’s blower. Switch off your furnace off instantly and reach our professionals at 386-313-8766 for support.
