When your furnace is operating like it should, it should give warmth without generating too much sound. While it’s expected to catch your furnace making noise as it begins running, other disruptions are showing your furnace needs immediate professional help.

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 pros are here to help with the best furnace repair in Richmond, British Columbia.

1. Furnace Makes a Banging Sound

You might have an urgent situation on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a couple of problems. These range from gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system turns dirty as time passes, so that’s why it’s critical to book yearly furnace maintenance with Refrigeration Systems Ltd.. One of the jobs our professionals do during this appointment is clean your furnace’s burners. When this component gets dirty, you might hear your furnace making a loud rumbling noise when ignition takes longer than normal. The resulting 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 vented outdoors. This dangerous gas can be lethal in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, Refrigeration Systems Ltd. urges you to turn it off and contacting us at 778-693-2532. Significant natural gas in your furnace or a cracked heat exchanger are dangerous issues that require immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to move warm air across your house. If the ductwork wasn’t designed properly or is aging, it can make a lot of noise when your furnace runs. This can be the problem if your furnace makes a banging noise when it shuts off. Call Refrigeration Systems Ltd. at 778-693-2532 and we’ll figure out the problem.

2. Furnace Makes a Buzzing Sound

If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually indicates an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves warm or cooled air throughout your rooms, and a capacitor, which turns on the motor. If either of these pieces are going out, 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 a loose screw, or something critical, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating professionals at 778-693-2532 for support.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to alert you it could use some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing could need to be greased. We realize that maintenance often slips your mind, but our technicians can get your furnace operating quietly again quickly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You could also hear whistling while the furnace is running if a floor vent isn’t secure. If you’ve checked your vents but are still hearing sound, Refrigeration Systems Ltd. can assist you. It’s important to get loose ductwork repaired without delay, since it can create comfort issues in your house and inflate your utility expenses.

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 racket typically means there’s an issue with your furnace’s blower. Switch off your furnace off promptly and reach our professionals at 778-693-2532 for help.
