When your furnace is running like it should, it should provide warmth without generating too much sound. While it’s common to catch your furnace making noise as it starts up, other sounds are showing your furnace requires immediate professional assistance.

Here are some of the most common furnace noises and what they could mean. If your furnace is making an atypical noise, our friendly heating specialists are here to help with the best furnace repair in Oxford, Mississippi.

1. Furnace Makes a Banging Sound

You may have a critical issue on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be several problems. These range from gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over time, so that’s why it’s essential to schedule routine furnace maintenance with Franklin's Heating & Air Conditioning, Inc. One of the jobs our professionals perform during this service is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise when ignition is delayed. The following gas buildup might break your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can leak carbon monoxide, which is normally emitted away from your home. This dangerous gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Franklin's Heating & Air Conditioning, Inc advises turning it off and contacting us at 662-281-1231. Excessive natural gas in your furnace or a broken heat exchanger are serious troubles that necessitate immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver hot air around your house. If the ductwork wasn’t installed correctly or is aging, it can be loud when your furnace is heating. This might be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Franklin's Heating & Air Conditioning, Inc at 662-281-1231 and we’ll determine the problem.

2. Furnace Buzzes Constantly

If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually means there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you might detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends warm or cold air throughout your house, and a capacitor, which triggers the motor. If either of these components 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 serious, like a broken component. In either case, we urge you to shut your furnace off and calling our heating professionals at 662-281-1231 for assistance.

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 needs some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing could need to be lubed. We are aware that maintenance often slips your mind, but our technicians can get your furnace heating quietly again quickly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also notice whistling while the furnace is running if a floor vent is loose. If you’ve checked your vents but are still hearing whistling, Franklin's Heating & Air Conditioning, Inc can assist you. It’s essential to get loose ductwork repaired quickly, because it can make comfort problems in your home and inflate your energy bills.

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 frequently means there’s a problem with your furnace’s blower. Switch off your furnace off now and reach us at 662-281-1231 for assistance.
