When your furnace is running like it should, it should provide heat without generating too much disruption. While it’s expected to hear your furnace making noise as it begins running, other sounds are indicating your furnace requires immediate professional assistance.

Here are some of the most frequent furnace noises and what they might be signaling. If your furnace is making a weird noise, our friendly heating specialists are here to help with the best furnace repair in Thedford, Ontario.

1. Furnace Makes Banging or Knocking Sounds

You could 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 may indicate there could be a few problems. These include gas building up in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over time, so that’s why it’s important to book routine furnace maintenance with Taylor's Heating & Air Conditioning. One of the things our technicians 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 after ignition is delayed. The subsequent gas buildup can break your furnace’s heat exchanger, where natural gas transforms into warm air. Any cracks in it can leak carbon monoxide, which is normally vented away from your home. This dangerous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Taylor's Heating & Air Conditioning urges you to turn it off and contacting us at 519-296-4437. Significant natural gas in your furnace or a fractured heat exchanger are serious troubles that should get prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide warm air throughout your home. If the ductwork wasn’t designed correctly or is getting dated, it can be loud when your furnace runs. This might be the problem if your furnace makes a banging noise when it shuts off. Call Taylor's Heating & Air Conditioning at 519-296-4437 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 often indicates an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to run on the proper voltage. If wires or the box is loose, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which sends warm or chilly air throughout your house, and a capacitor, which turns on the motor. If either of these parts 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 the result of something little, like an unfastened screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating specialists at 519-296-4437 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to tell you it requires some TLC. If you’ve skipped furnace maintenance recently, belts could be worn out or a bearing may need to be lubricated. We realize that maintenance frequently slips your mind, but our techs can get your furnace heating quietly again rapidly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You could also hear whistling while the furnace is on if a floor vent isn’t secure. If you’ve checked your vents but are still sensing sound, Taylor's Heating & Air Conditioning can assist you. It’s essential to get loose ductwork taken care of quickly, since it can create comfort troubles in your house and drive up your gas costs.

6. Furnace Making a Grinding Noise

It’s not a good sign if you notice your furnace making a grinding noise. This metal-on-metal noise typically means there’s trouble with your furnace’s blower. Switch off your furnace off now and contact our professionals at 519-296-4437 for assistance.
