When your furnace is operating like it should, it should provide heat without generating too much noise. While it’s expected to notice your furnace making noise as it begins running, other noises are indicating your furnace requires immediate professional help.

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

1. Furnace Making a Banging Noise

You may 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 several problems. These include gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy over time, so that’s why it’s important to book annual furnace maintenance with Franklin's Heating & Air Conditioning, Inc. One of the jobs our technicians perform during this work is clean your furnace’s burners. When this piece gets grimy, you might hear your furnace making a loud rumbling noise if ignition takes more time. The ensuing gas buildup may crack your furnace’s heat exchanger, where natural gas changes into heat. Any breaks in it can discharge carbon monoxide, which is normally released away from your home. This hazardous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Franklin's Heating & Air Conditioning, Inc recommends turning it off and reaching us at 662-281-1231. Significant natural gas in your furnace or a fractured heat exchanger are hazardous troubles that require immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver heated air around your residence. If the ductwork wasn’t installed correctly or is getting old, it can make a lot of noise when your furnace is on. This might be the problem if your furnace makes a banging noise when it shuts off. Call Franklin's Heating & Air Conditioning, Inc at 662-281-1231 and we’ll pinpoint the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace relies on an internal transformer to operate on the right voltage. If wires or the box is loose, you might detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or chilly air throughout your space, and a capacitor, which triggers the motor. If either of these parts 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 due to something little, like a loose screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating professionals at 662-281-1231 for help.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to get your attention it could use some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubed. We realize that maintenance frequently slips your mind, but our professionals can get your furnace running quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also be aware of whistling while the furnace is operating if a floor vent isn’t secure. If you’ve examined your vents but are still hearing noise, Franklin's Heating & Air Conditioning, Inc can help. It’s essential to get loose ductwork taken care of quickly, as it can make comfort problems in your home and inflate your heating bills.

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 sound frequently means there’s trouble with your furnace’s blower. Shut down your furnace off now and reach our professionals at 662-281-1231 for assistance.
