When your furnace is running properly, it should give warm air without creating too much noise. While it’s normal to hear your furnace making noise as it starts up, other sounds are signaling your furnace should get immediate professional support.

Here are some of the most common furnace noises and what they might mean. If your furnace is making an odd noise, our friendly heating pros are here to fix the problem with the best furnace repair in Weatherford, Texas.

1. Furnace Making a Banging Noise

You could have a critical issue on your hands if you’re hearing 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 increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over time, so that’s why it’s important to book yearly furnace maintenance with Parker County Cooling & Heating. One of the things our professionals do during this service is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise if ignition takes more time. The resulting gas buildup may crack your furnace’s heat exchanger, where natural gas changes into heat. Any cracks in it can discharge carbon monoxide, which is regularly emitted away from your home. 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 urges you to turn it off and contacting us at 817-380-5213. Significant natural gas in your furnace or a cracked heat exchanger are critical problems that should get fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to move heated air around your house. If the ductwork wasn’t installed properly or is getting old, it can be noisy when your furnace is heating. This might 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 determine 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 usually is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the correct 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 distributes hot or cooled air around your home, and a capacitor, which starts the motor. If either of these components are fading, they will buzz when the furnace starts.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it could be due to something little, like a loose screw, or something serious, like a broken part. In either case, we urge you to shut your furnace off and contacting our heating pros 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 running, it’s attempting to get your attention it requires some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing could need to be lubricated. We are aware that maintenance sometimes 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 detecting your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also hear whistling while the furnace is on if a floor vent is loose. If you’ve checked your vents but are still sensing sound, Parker County Cooling & Heating can assist you. It’s important to get loose ductwork taken care of without delay, because it can create comfort problems in your residence and drive up your heating bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good sign if you detect 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 call our professionals at 817-380-5213 for assistance.
