When your furnace is working correctly, it should give heat without creating too much sound. While it’s common to catch your furnace making noise as it turns on, other sounds are showing your furnace needs immediate professional assistance.

Here are some of the most frequent furnace noises and what they might be indicating. If your furnace is making an odd noise, our friendly heating professionals are here to help with the best furnace repair in Weatherford, Texas.

1. Furnace Makes a Banging Sound

You may 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 few problems. These range from gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system becomes grimy over the years, so that’s why it’s important to schedule yearly furnace maintenance with Parker County Cooling & Heating. One of the tasks our pros do during this appointment is clean your furnace’s burners. When this piece gets grimy, you could hear your furnace making a loud rumbling noise if ignition is delayed. The following gas buildup might fracture your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can emit carbon monoxide, which is ordinarily emitted outdoors. This hazardous gas can be lethal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Parker County Cooling & Heating advises turning it off and reaching us at 817-380-5213. Significant natural gas in your furnace or a cracked heat exchanger are dangerous problems that necessitate fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move heated air throughout your residence. If the ductwork wasn’t designed right or is getting old, it can be loud 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 Parker County Cooling & Heating at 817-380-5213 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 frequently is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box is loose, you may notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes heated or cooled air throughout your rooms, and a capacitor, which triggers the motor. If either of these pieces 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 the result of something minor, like an unfastened screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and calling our heating pros 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 trying to get your attention it needs some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be greased. We know that maintenance often slips your mind, but our techs can get your furnace heating quietly again rapidly.

5. Furnace Whistles

When you’re detecting 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 noticing noise, Parker County Cooling & Heating can help. It’s important to get loose ductwork repaired fast, because it can make comfort issues in your home and drive up your utility expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal sound frequently means there’s a problem with your furnace’s blower. Shut down your furnace off right away and contact our pros at 817-380-5213 for support.
