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 pros are here to assist with the best furnace repair in Kirkfield Heating, Manitoba.
1. Furnace Making a Banging Noise
You might have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a couple of problems. These involve gas building up in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system becomes grimy over time, so that’s why it’s essential to book seasonal furnace maintenance with Kirkfield Heating & Air Conditioning. One of the things our technicians complete during this appointment is clean your furnace’s burners. When this piece gets grimy, you may hear your furnace making a loud rumbling noise after ignition is delayed. The following gas buildup might fracture your furnace’s heat exchanger, where natural gas transforms into warm air. Any breaks in it can discharge carbon monoxide, which is ordinarily vented away from your home. This hazardous gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Kirkfield Heating & Air Conditioning recommends turning it off and contacting us at 204-272-8128. Excessive natural gas in your furnace or a cracked heat exchanger are dangerous issues that should get prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver heated air across your home. If the ductwork wasn’t installed right or is getting dated, it can be loud when your furnace is on. This can be the issue if your furnace makes a banging noise when it shuts off. Call Kirkfield Heating & Air Conditioning at 204-272-8128 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently means there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to operate on the correct 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 works with a blower motor, which moves hot or cooled air across your home, and a capacitor, which turns on 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 might be the result of something little, like an unfastened screw, or something critical, like a broken part. In either case, we urge you to shut your furnace off and calling our heating specialists at 204-272-8128 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s attempting to get your attention it needs some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be dilapidated or a bearing may need to be lubricated. We know that maintenance sometimes slips your mind, but our techs can get your furnace heating quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You might also notice whistling while the furnace is working if a floor vent is loose. If you’ve looked at your vents but are still sensing noise, Kirkfield Heating & Air Conditioning can help. It’s important to get loose ductwork repaired quickly, as it can result in comfort issues in your home and increase your gas costs.
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 typically means there’s trouble with your furnace’s blower. Turn off your furnace off immediately and contact us at 204-272-8128 for help.
