When your furnace is running like it should, it should provide warm air without generating too much sound. While it’s normal to hear your furnace making noise as it starts up, other sounds are signaling your furnace needs immediate professional assistance.

Here are some of the most reported furnace noises and what they could be indicating. If your furnace is making an odd noise, our friendly heating pros are here to fix the problem with the best furnace repair in Chatsworth, Georgia.

1. Furnace Makes Banging or Knocking Sounds

You might have a critical situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can indicate there could be a few problems. These involve gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over the years, so that’s why it’s critical to set yearly furnace maintenance with True Temp Heating & Air Conditioning. One of the things our pros do during this appointment is clean your furnace’s burners. When this part gets grimy, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The ensuing gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into warmth. Any cracks in it can discharge carbon monoxide, which is regularly released away from your home. This toxic gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, True Temp Heating & Air Conditioning recommends turning it off and contacting us at 706-695-7492. Significant natural gas in your furnace or a broken heat exchanger are hazardous issues that require immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver warm air across your house. If the ductwork wasn’t installed properly or is getting old, it can make a lot of noise when your furnace runs. This may be the problem if your furnace makes a banging noise when it shuts off. Call True Temp Heating & Air Conditioning at 706-695-7492 and we’ll determine 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 uses an internal transformer to run on the proper voltage. If wires or the box is loose, you might hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes hot or cold air around your home, and a capacitor, which triggers 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 may be related to something minor, like a loose screw, or something major, like a broken piece. In either case, we urge you to shut your furnace off and getting in touch with our heating professionals at 706-695-7492 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to get your attention it needs some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be lubed. We realize that maintenance sometimes slips your mind, but our techs can get your furnace running quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re noticing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You may also hear whistling while the furnace is on if a floor vent is loose. If you’ve looked at your vents but are still sensing sound, True Temp Heating & Air Conditioning can provide support. It’s important to get loose ductwork repaired fast, since it can make comfort problems in your home and drive up your energy bills.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise usually means there’s an issue with your furnace’s blower. Shut down your furnace off now and reach us at 706-695-7492 for help.
