When your furnace is operating like it should, it should provide warm air without making too much disruption. While it’s normal to catch your furnace making noise as it starts up, other disruptions are indicating your furnace requires immediate professional assistance.

Here are some of the most common furnace noises and what they might mean. If your furnace is making a weird noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Muldrow, Oklahoma.

1. Furnace Making a Banging Noise

You may have a serious problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be several problems. These include gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty over the years, so that’s why it’s critical to schedule yearly furnace maintenance with Air Service Co.. One of the tasks our technicians do during this appointment is clean your furnace’s burners. When this piece gets grimy, you may hear your furnace making a loud rumbling noise after ignition is delayed. The subsequent gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can emit carbon monoxide, which is ordinarily released outdoors. This dangerous gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Air Service Co. recommends turning it off and calling us at 918-212-8943. Too much natural gas in your furnace or a cracked heat exchanger are dangerous issues 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 right or is getting dated, it can be loud when your furnace runs. This might be the problem if your furnace makes a banging noise when it shuts off. Contact Air Service Co. at 918-212-8943 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically means there’s an electrical situation, 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 isn’t tight enough, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or chilly air around your house, and a capacitor, which triggers the motor. If either of these parts are going out, they will buzz when the furnace turns on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it may be due to something little, like a loose screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 918-212-8943 for help.

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 tell you it requires some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing could need to be greased. We are aware that maintenance sometimes slips your mind, but our techs can get your furnace operating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s typically 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 tight. If you’ve examined your vents but are still hearing sound, Air Service Co. can assist you. It’s critical to get loose ductwork fixed fast, since it can create comfort troubles in your home and inflate your heating expenses.

6. Furnace Making a Grinding Noise

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal sound typically means there’s trouble with your furnace’s blower. Switch off your furnace off promptly and contact our professionals at 918-212-8943 for assistance.
