1. Furnace Making a Banging Noise

You may have a critical situation on your hands if you’re hearing 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 accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over the years, so that’s why it’s important to schedule yearly 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 component gets grimy, you may hear your furnace making a loud rumbling noise after ignition takes more time. The resulting gas buildup can fracture your furnace’s heat exchanger, where natural gas turns into warmth. Any fractures in it can emit carbon monoxide, which is regularly vented outside. This dangerous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Franklin's Heating & Air Conditioning, Inc urges you to turn it off and calling us at 662-281-1231. Excessive natural gas in your furnace or a fractured heat exchanger are serious issues that necessitate fast service.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide hot air throughout your home. If the ductwork wasn’t designed properly or is getting old, it can make a lot of noise when your furnace is heating. This could be the issue if your furnace makes a banging noise when it shuts off. Contact Franklin's Heating & Air Conditioning, Inc at 662-281-1231 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace depends on an internal transformer to work on the right voltage. If wires or the box isn’t tight enough, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or cooled air around your residence, 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 related to something little, like an unfastened screw, or something critical, like a broken part. In either case, we recommend shutting off your furnace and calling our heating specialists at 662-281-1231 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to get your attention it needs some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing could need to be greased. We know that maintenance sometimes slips your mind, but our professionals can get your furnace running quietly again quickly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You might also be aware of whistling while the furnace is running if a floor vent is loose. If you’ve examined your vents but are still hearing sound, Franklin's Heating & Air Conditioning, Inc can provide support. It’s important to get loose ductwork fixed fast, since it can result in comfort issues in your residence and inflate your gas bills.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal noise typically means there’s an issue with your furnace’s blower. Switch off your furnace off right away and contact our pros at 662-281-1231 for help.
