1. Furnace Makes Banging or Knocking Sounds

You may have a critical 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 a couple of problems. These involve gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over the years, so that’s why it’s important to set seasonal furnace maintenance with Hix Air Conditioning Service, Inc.. One of the jobs our pros perform during this appointment is clean your furnace’s burners. When this part gets dirty, you might hear your furnace making a loud rumbling noise if ignition is delayed. The ensuing gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can discharge carbon monoxide, which is regularly vented outside. This toxic gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Hix Air Conditioning Service, Inc. advises turning it off and calling us at 918-682-8238. Significant natural gas in your furnace or a fractured heat exchanger are hazardous issues that necessitate prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move warm air around your residence. If the ductwork wasn’t installed properly or is getting old, it can be noisy when your furnace is heating. This could be the issue 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 Buzzes Constantly

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

Your furnace uses an internal transformer to work on the proper voltage. If wires or the box needs to be tightened, you might detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or cold air around your space, and a capacitor, which turns on the motor. If either of these parts are going out, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it could 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 specialists at 918-682-8238 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to get your attention it requires some TLC. If you’ve neglected furnace maintenance recently, belts could be worn down or a bearing might need to be lubricated. We know that maintenance often slips your mind, but our professionals can get your furnace operating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent is loose. If you’ve looked at your vents but are still sensing whistling, Hix Air Conditioning Service, Inc. can provide support. It’s critical to get loose ductwork taken care of quickly, because it can result in comfort issues in your residence and drive up your energy bills.

6. Furnace Making a Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal racket often means there’s trouble with your furnace’s blower. Shut down your furnace off instantly and reach us at 918-682-8238 for help.
