When your furnace is running like it should, it should give warmth without generating too much disruption. While it’s common to hear your furnace making noise as it begins running, other noises are indicating your furnace requires immediate professional assistance.

Here are some of the most common furnace noises and what they could be indicating. If your furnace is making a strange noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Muskogee, Oklahoma.

1. Furnace Makes a Banging Sound

You could have a critical situation 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 several problems. These range from gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over time, so that’s why it’s important to book annual furnace maintenance with Hix Air Conditioning Service, Inc.. One of the jobs our pros do during this service is clean your furnace’s burners. When this part gets grimy, you may hear your furnace making a loud rumbling noise when ignition takes more time. The resulting gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can leak carbon monoxide, which is ordinarily emitted away from your home. This dangerous gas can be lethal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Hix Air Conditioning Service, Inc. urges you to turn it off and calling us at 918-682-8238. Excessive natural gas in your furnace or a broken heat exchanger are critical troubles that should get prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move hot air across your home. If the ductwork wasn’t put in properly or is aging, it can be loud when your furnace runs. This could be the case if your furnace makes a banging noise when it shuts off. Call Hix Air Conditioning Service, Inc. at 918-682-8238 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound often indicates an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to work on the right voltage. If wires or the box needs to be tightened, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves warm or chilly air around your house, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace switches on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be related to something minor, like an unsecure screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and calling our heating pros at 918-682-8238 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to tell you it requires some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing could need to be lubed. We know that maintenance sometimes slips your mind, but our professionals can get your furnace running quietly again rapidly.

5. Furnace Whistles

When you’re hearing 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 checked your vents but are still sensing noise, Hix Air Conditioning Service, Inc. can assist you. It’s important to get loose ductwork fixed fast, as it can create comfort troubles in your house and inflate your energy expenses.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal noise often means there’s an issue with your furnace’s blower. Switch off your furnace off now and reach our professionals at 918-682-8238 for help.
