1. Furnace Makes a Banging Sound
You might have a serious problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a couple of problems. These include gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty as time passes, so that’s why it’s critical to schedule yearly furnace maintenance with Lakeside Heating & Air. One of the tasks our technicians do during this service is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise if ignition takes more time. The subsequent gas buildup may break your furnace’s heat exchanger, where natural gas changes into warm air. Any fractures in it can discharge carbon monoxide, which is ordinarily emitted away from your home. This toxic gas can be lethal in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Lakeside Heating & Air recommends turning it off and calling us at 509-284-4265. Significant natural gas in your furnace or a broken heat exchanger are serious issues that require fast service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move heated air across your residence. If the ductwork wasn’t put in right or is getting old, it can be loud when your furnace runs. This can be the case if your furnace makes a banging noise when it shuts off. Contact Lakeside Heating & Air at 509-284-4265 and we’ll pinpoint the problem.
2. Furnace Makes a Buzzing Sound
If you notice your furnace making a buzzing noise, don’t wait to call us. A buzzing sound typically is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses 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 sends heated or chilly air across your residence, and a capacitor, which turns on the motor. If either of these parts are failing, they will buzz when the furnace switches on.
3. Furnace Rattles
If your furnace is making a rattling noise, it could be the result of something little, like an unsecure screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and calling our heating specialists at 509-284-4265 for help.
4. Furnace Is Making a High-Pitched Squealing Sound
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s attempting to get your attention it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing might need to be lubricated. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace running quietly again fast.
5. Furnace Whistles
When you’re noticing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You could also notice whistling while the furnace is running if a floor vent isn’t tight. If you’ve examined your vents but are still noticing whistling, Lakeside Heating & Air can assist you. It’s critical to get loose ductwork taken care of fast, because it can make comfort troubles in your residence and increase your energy bills.
6. Furnace Makes a Loud, Unpleasant Grinding Noise
It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal noise typically means there’s trouble with your furnace’s blower. Turn off your furnace off right away and reach our professionals at 509-284-4265 for support.
