When your furnace is running like it should, it should provide heat without generating too much sound. While it’s normal to notice your furnace making noise as it begins running, other disruptions are showing your furnace needs immediate professional support.

Here are some of the most reported furnace noises and what they could be signaling. If your furnace is making an odd noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Winnipeg, Manitoba.

1. Furnace Makes Banging or Knocking Sounds

You might have a critical problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may mean there could be a couple of problems. These include gas increasing in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy as time passes, so that’s why it’s essential to book yearly furnace maintenance with Kirkfield Heating & Air Conditioning. One of the things our professionals complete during this service is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise when ignition is delayed. The ensuing gas buildup can break your furnace’s heat exchanger, where natural gas transforms into warmth. Any breaks in it can leak carbon monoxide, which is ordinarily vented outside. This dangerous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Kirkfield Heating & Air Conditioning recommends turning it off and reaching us at 204-272-8128. Too much natural gas in your furnace or a ruptured heat exchanger are hazardous problems that require immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide hot air across your house. If the ductwork wasn’t designed properly or is aging, it can be noisy when your furnace is on. This can be the problem 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 notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically indicates an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to work on the right voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes heated or chilly air around your rooms, and a capacitor, which triggers the motor. If either of these pieces 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 may be related to something little, like an unfastened screw, or something serious, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating specialists at 204-272-8128 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to alert you it could use some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing may need to be lubricated. We realize that maintenance frequently slips your mind, but our technicians can get your furnace heating quietly again fast.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You may also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve examined your vents but are still sensing noise, Kirkfield Heating & Air Conditioning can assist you. It’s important to get loose ductwork fixed quickly, as it can make comfort problems in your home and drive up your gas costs.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket frequently means there’s trouble with your furnace’s blower. Shut down your furnace off right away and call our pros at 204-272-8128 for assistance.
