When your furnace is working properly, it should deliver warm air without making too much noise. While it’s normal to hear your furnace making noise as it begins running, other disruptions are showing your furnace should get immediate professional help.

Here are some of the most common furnace noises and what they might be signaling. If your furnace is making a strange noise, our friendly heating specialists are here to assist with the best furnace repair in Gardnerville, Nevada.

1. Furnace Making a Banging Noise

You may have an urgent situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These include gas building up in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system turns filthy over the years, so that’s why it’s essential to set seasonal furnace maintenance with Beach & Sons Mechanical, Inc.. One of the tasks our pros complete during this service is clean your furnace’s burners. When this component gets dirty, you might hear your furnace making a loud rumbling noise when ignition is delayed. The ensuing gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any fractures in it can discharge carbon monoxide, which is ordinarily released away from your home. This dangerous gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Beach & Sons Mechanical, Inc. recommends turning it off and contacting us at 775-782-0055. Excessive natural gas in your furnace or a cracked heat exchanger are serious issues that require prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide hot air around your home. If the ductwork wasn’t put in correctly or is getting old, it can be noisy when your furnace is heating. This can be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Beach & Sons Mechanical, Inc. at 775-782-0055 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

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

Your furnace relies on an internal transformer to run on the right voltage. If wires or the box isn’t tight enough, you may notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or cold air throughout your rooms, and a capacitor, which starts the motor. If either of these components are fading, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it may be the result of something minor, like a loose screw, or something major, like a broken part. In either case, we urge you to shut your furnace off and calling our heating specialists at 775-782-0055 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to get your attention it requires some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing could need to be greased. We are aware that maintenance sometimes slips your mind, but our techs can get your furnace operating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve checked your vents but are still hearing sound, Beach & Sons Mechanical, Inc. can provide support. It’s essential to get loose ductwork repaired without delay, since it can result in comfort troubles in your home and increase your heating bills.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal sound typically means there’s a problem with your furnace’s blower. Shut down your furnace off right away and reach our professionals at 775-782-0055 for support.
