When your furnace is working like it should, it should deliver warm air without creating too much disruption. While it’s common to hear your furnace making noise as it starts up, other disruptions are indicating your furnace requires immediate professional support.

Here are some of the most reported furnace noises and what they can mean. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Weatherford, Texas.

1. Furnace Makes a Banging Sound

You could have a serious situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a couple of problems. These involve gas accumulating in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over time, so that’s why it’s important to set seasonal furnace maintenance with Parker County Cooling & Heating. One of the jobs our technicians do during this appointment is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise when ignition takes more time. The following gas buildup may fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any fractures in it can emit carbon monoxide, which is regularly emitted outdoors. This hazardous gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Parker County Cooling & Heating recommends turning it off and calling us at 817-380-5213. Too much natural gas in your furnace or a fractured heat exchanger are critical issues that should get fast service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move heated air throughout your house. If the ductwork wasn’t designed correctly or is getting dated, it can make a lot of noise when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Call Parker County Cooling & Heating at 817-380-5213 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

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

Your furnace depends on an internal transformer to work on the correct voltage. If wires or the box needs to be tightened, you might hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends heated or cold air across your space, and a capacitor, which turns on the motor. If either of these components 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 may be due to something small, like a loose screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and calling our heating specialists at 817-380-5213 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying 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 might need to be lubed. We know that maintenance frequently slips your mind, but our techs can get your furnace heating quietly again fast.

5. Furnace Making a Whistling Noise

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 notice whistling while the furnace is running if a floor vent isn’t secure. If you’ve examined your vents but are still noticing noise, Parker County Cooling & Heating can assist you. It’s essential to get loose ductwork fixed without delay, because it can create comfort troubles in your residence and increase your heating expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal sound often means there’s a problem with your furnace’s blower. Switch off your furnace off instantly and reach us at 817-380-5213 for assistance.
