When your furnace is working like it should, it should give warm air without creating too much disruption. While it’s normal to catch your furnace making noise as it turns on, other sounds are showing your furnace requires immediate professional assistance.
Here are some of the most reported furnace noises and what they could be indicating. If your furnace is making a weird noise, our friendly heating professionals are here to fix the problem with the best furnace repair in Winnipeg, Manitoba.
1. Furnace Making a Banging Noise
You may have a serious 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 several problems. These include gas increasing in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy as time passes, so that’s why it’s essential to schedule yearly furnace maintenance with Kirkfield Heating & Air Conditioning. One of the jobs our techs complete during this work is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise after ignition takes longer than normal. The resulting gas buildup may crack your furnace’s heat exchanger, where natural gas turns into heat. Any fractures in it can emit carbon monoxide, which is normally emitted outside. This toxic gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Kirkfield Heating & Air Conditioning urges you to turn it off and reaching us at 204-272-8128. Too much natural gas in your furnace or a fractured heat exchanger are serious problems that should get fast repairs.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide warm air around your residence. If the ductwork wasn’t put in correctly or is getting dated, it can be loud when your furnace is heating. This might be the case if your furnace makes a banging noise when it shuts off. Contact Kirkfield Heating & Air Conditioning at 204-272-8128 and we’ll determine 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 means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to run on the correct voltage. If wires or the box needs to be tightened, you may detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which distributes warm or cold air around your home, and a capacitor, which starts the motor. If either of these components are fading, they will buzz when the furnace starts.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it could be related to something minor, like an unsecure screw, or something major, like a broken component. In either case, we advise shutting your furnace off and contacting our heating pros at 204-272-8128 for help.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to tell you it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing might need to be lubricated. We realize that maintenance often slips your mind, but our pros can get your furnace running quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re hearing 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 secure. If you’ve checked your vents but are still noticing sound, Kirkfield Heating & Air Conditioning can help. It’s essential to get loose ductwork repaired without delay, since it can make comfort problems in your residence and inflate your utility bills.
6. Furnace Making a Grinding Noise
It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal sound frequently means there’s trouble with your furnace’s blower. Switch off your furnace off right away and reach us at 204-272-8128 for support.
