When your furnace is working properly, it should deliver warmth without generating too much disruption. While it’s expected to catch your furnace making noise as it turns on, other disruptions are indicating your furnace requires immediate professional assistance.

Here are some of the most frequent furnace noises and what they might mean. If your furnace is making a weird noise, our friendly heating pros are here to assist with the best furnace repair in Weatherford, Texas.

1. Furnace Makes a Banging Sound

You might 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 may indicate there could be several problems. These include gas increasing in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over time, so that’s why it’s critical to set seasonal furnace maintenance with Parker County Cooling & Heating. One of the jobs our professionals complete during this appointment is clean your furnace’s burners. When this component gets dirty, you might hear your furnace making a loud rumbling noise after ignition takes longer than normal. The ensuing gas buildup can crack your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can discharge carbon monoxide, which is ordinarily emitted outdoors. This toxic gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Parker County Cooling & Heating urges you to turn it off and reaching us at 817-380-5213. Excessive natural gas in your furnace or a fractured heat exchanger are serious issues that necessitate immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver hot air across your home. If the ductwork wasn’t installed properly or is getting dated, it can be loud when your furnace runs. This might be the case if your furnace makes a banging noise when it shuts off. Call Parker County Cooling & Heating at 817-380-5213 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

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

Your furnace uses an internal transformer to operate on the right voltage. If wires or the box is loose, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends heated or chilly air throughout your residence, and a capacitor, which turns on the motor. If either of these parts are failing, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be related to something little, like an unsecure screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating professionals at 817-380-5213 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to get your attention it needs some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing might need to be greased. We realize that maintenance often slips your mind, but our professionals can get your furnace heating quietly again fast.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You could also hear whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still hearing whistling, Parker County Cooling & Heating can provide support. It’s critical to get loose ductwork taken care of quickly, because it can create comfort troubles in your house and inflate your utility expenses.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal noise often means there’s an issue with your furnace’s blower. Turn off your furnace off right away and call us at 817-380-5213 for help.
