1. Furnace Makes a Banging Sound
You may have an urgent problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a few problems. These involve gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy as time passes, so that’s why it’s critical to schedule yearly furnace maintenance with A&A Air Conditioning, Heating & Sheet Metal. One of the things our technicians complete during this work is clean your furnace’s burners. When this part gets grubby, you might hear your furnace making a loud rumbling noise after ignition takes more time. The subsequent gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into heat. Any fractures in it can leak carbon monoxide, which is ordinarily vented away from your home. This toxic gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, A&A Air Conditioning, Heating & Sheet Metal advises turning it off and reaching us at 530-273-1301. Significant natural gas in your furnace or a ruptured heat exchanger are hazardous troubles that require fast service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to deliver hot air across your house. If the ductwork wasn’t put in right or is aging, it can be noisy when your furnace runs. This might be the issue if your furnace makes a banging noise when it shuts off. Contact A&A Air Conditioning, Heating & Sheet Metal at 530-273-1301 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace relies on 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 sends warm or cooled air across your rooms, and a capacitor, which turns on the motor. If either of these parts 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 can be due to something little, like an unsecure screw, or something critical, like a broken component. In either case, we recommend shutting off your furnace and calling our heating specialists at 530-273-1301 for help.
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 skipped furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be greased. We know that maintenance sometimes slips your mind, but our pros can get your furnace heating quietly again quickly.
5. Furnace Whistles
When you’re noticing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You could also hear whistling while the furnace is working if a floor vent is loose. If you’ve looked at your vents but are still hearing whistling, A&A Air Conditioning, Heating & Sheet Metal can assist you. It’s critical to get loose ductwork repaired fast, as it can make comfort issues in your house and drive up your gas expenses.
6. Furnace Making a Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal sound often means there’s trouble with your furnace’s blower. Switch off your furnace off instantly and call our pros at 530-273-1301 for help.
