When your furnace is running correctly, it should deliver warm air without creating too much noise. While it’s normal to notice your furnace making noise as it begins running, other disruptions are indicating your furnace should get immediate professional assistance.

Here are some of the most frequent furnace noises and what they could be signaling. If your furnace is making a weird noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Sandpoint, Idaho.

1. Furnace Making a Banging Noise

You could 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 a couple of problems. These range from gas building up in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over the years, so that’s why it’s critical to book annual furnace maintenance with Age Heating & Cooling. One of the things our professionals perform during this work is clean your furnace’s burners. When this piece gets grimy, you could hear your furnace making a loud rumbling noise when ignition is delayed. The ensuing gas buildup may crack your furnace’s heat exchanger, where natural gas turns into warmth. Any cracks in it can emit carbon monoxide, which is regularly vented outdoors. This dangerous gas can be fatal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Age Heating & Cooling recommends turning it off and reaching us at 208-603-2210. Too much natural gas in your furnace or a broken heat exchanger are serious problems that necessitate fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide hot air across your home. If the ductwork wasn’t put in right or is getting old, it can be loud when your furnace is heating. This may be the problem if your furnace makes a banging noise when it shuts off. Contact Age Heating & Cooling at 208-603-2210 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to work on the proper 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 has a blower motor, which distributes hot or cold air around your home, and a capacitor, which turns on the motor. If either of these components are going out, they will buzz when the furnace starts.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it could be related to something minor, like a loose screw, or something critical, like a broken component. In either case, we advise shutting your furnace off and calling our heating pros at 208-603-2210 for support.

4. Furnace Making a Squealing Noise

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 forgotten furnace maintenance recently, belts could be worn out or a bearing might need to be lubed. We are aware that maintenance frequently slips your mind, but our techs can get your furnace operating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You may also be aware of whistling while the furnace is operating if a floor vent is loose. If you’ve checked your vents but are still sensing noise, Age Heating & Cooling can help. It’s critical to get loose ductwork repaired quickly, because it can result in comfort troubles in your residence and increase your gas expenses.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you detect your furnace making a grinding noise. This metal-on-metal noise frequently means there’s trouble with your furnace’s blower. Turn off your furnace off instantly and contact our professionals at 208-603-2210 for help.
