When your furnace is running like it should, it should give heat without generating too much disruption. While it’s expected to hear your furnace making noise as it turns on, other sounds are indicating your furnace should get immediate professional support.

Here are some of the most frequent furnace noises and what they could be indicating. If your furnace is making an odd noise, our friendly heating pros are here to help with the best furnace repair in Cocoa, Florida.

1. Furnace Makes Banging or Knocking Sounds

You might have a serious problem on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a few problems. These involve gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy over time, so that’s why it’s critical to book routine furnace maintenance with The Chilly Pig. One of the jobs our technicians do during this appointment is clean your furnace’s burners. When this component gets dirty, you might hear your furnace making a loud rumbling noise after ignition is delayed. The resulting gas buildup can break your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can leak carbon monoxide, which is regularly vented away from your home. This toxic gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, The Chilly Pig urges you to turn it off and contacting us at 321-205-1234. Too much natural gas in your furnace or a broken heat exchanger are hazardous troubles that necessitate immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide hot air around your home. If the ductwork wasn’t designed properly or is aging, it can be noisy when your furnace runs. This might be the case if your furnace makes a banging noise when it shuts off. Get in touch with The Chilly Pig at 321-205-1234 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace uses an internal transformer to operate on the proper 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 sends hot or chilly air around your residence, and a capacitor, which turns on the motor. If either of these pieces are fading, they will buzz when the furnace switches on.

3. Furnace Rattles

If your furnace is making a rattling noise, it may be the result of something small, like an unsecure screw, or something critical, like a broken piece. In either case, we recommend shutting off your furnace and contacting our heating pros at 321-205-1234 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to alert you it needs some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn down or a bearing might need to be greased. We realize that maintenance sometimes slips your mind, but our techs can get your furnace running quietly again fast.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve looked at your vents but are still sensing whistling, The Chilly Pig can assist you. It’s critical to get loose ductwork fixed fast, since it can create comfort issues in your home and inflate your heating costs.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal racket frequently means there’s an issue with your furnace’s blower. Turn off your furnace off instantly and call us at 321-205-1234 for assistance.
