When your furnace is operating properly, it should give warmth without making too much sound. While it’s normal to notice your furnace making noise as it starts up, other sounds are showing your furnace needs immediate professional assistance.
Here are some of the most reported furnace noises and what they could be signaling. If your furnace is making a strange noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Winnipeg, Manitoba.
1. Furnace Making a Banging Noise
You may have a critical situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might indicate there could be a couple of problems. These range from gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over the years, so that’s why it’s important to schedule yearly furnace maintenance with Kirkfield Heating & Air Conditioning. One of the things our techs do during this work is clean your furnace’s burners. When this piece gets grimy, you may hear your furnace making a loud rumbling noise if ignition takes more time. The subsequent gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into warm air. Any cracks in it can emit carbon monoxide, which is normally emitted outside. This dangerous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Kirkfield Heating & Air Conditioning recommends turning it off and calling us at 204-272-8128. Too much natural gas in your furnace or a fractured heat exchanger are dangerous problems that require immediate service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to provide warm air across your residence. If the ductwork wasn’t designed right or is getting old, it can be loud when your furnace is on. This may be the problem if your furnace makes a banging noise when it shuts off. Contact Kirkfield Heating & Air Conditioning at 204-272-8128 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you notice 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 relies on an internal transformer to operate on the right voltage. If wires or the box isn’t tight enough, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes warm or cooled air across your house, and a capacitor, which triggers the motor. If either of these parts are fading, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it could be related to something small, like an unfastened screw, or something major, like a broken piece. In either case, we recommend shutting off your furnace and calling our heating specialists at 204-272-8128 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to tell you it requires some TLC. If you’ve forgotten 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 professionals can get your furnace operating quietly again fast.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You could also notice whistling while the furnace is working if a floor vent is loose. If you’ve examined your vents but are still hearing whistling, Kirkfield Heating & Air Conditioning can assist you. It’s critical to get loose ductwork repaired fast, because it can make comfort issues in your house and inflate 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 usually means there’s a problem with your furnace’s blower. Switch off your furnace off promptly and reach our pros at 204-272-8128 for support.
