October 13, 2020

When your furnace is running correctly, it should deliver heat without making too much sound. While it’s common to notice your furnace making noise as it begins running, other noises are showing your furnace requires immediate professional assistance.

Here are some of the most frequent furnace noises and what they might mean. If your furnace is making an odd noise, our friendly heating specialists are here to help with the best furnace repair in Muldrow, OK.

1. Furnace Making a Banging Noise

You could have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a couple of problems. These involve gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over the years, so that’s why it’s important to schedule routine furnace maintenance with Air Service Co.. One of the jobs our professionals perform during this appointment is clean your furnace’s burners. When this part gets grubby, you may hear your furnace making a loud rumbling noise after ignition is delayed. The subsequent gas buildup can break your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can discharge carbon monoxide, which is regularly released outdoors. This toxic gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Air Service Co. advises turning it off and reaching us at 918-212-8943. Excessive natural gas in your furnace or a ruptured heat exchanger are critical troubles that necessitate immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide warm air throughout your residence. If the ductwork wasn’t put in properly or is getting old, it can be loud when your furnace runs. This could be the case if your furnace makes a banging noise when it shuts off. Get in touch with Air Service Co. at 918-212-8943 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you observe your furnace making a buzzing noise, don’t hesitate 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 proper voltage. If wires or the box needs to be tightened, you may notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends warm or cooled air across your space, and a capacitor, which turns on the motor. If either of these components are failing, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be related to something small, like a loose screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating pros 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 going, it’s attempting to alert you it could use some TLC. If you’ve neglected furnace maintenance the past few years, belts could be dilapidated or a bearing may need to be lubricated. We are aware that maintenance sometimes slips your mind, but our technicians can get your furnace heating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You might also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve examined your vents but are still sensing noise, Air Service Co. can assist you. It’s critical to get loose ductwork repaired without delay, as it can make comfort issues in your house and inflate your utility costs.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket usually means there’s a problem with your furnace’s blower. Shut down your furnace off instantly and reach us at 918-212-8943 for help.
