When your furnace is running correctly, it should provide warm air without creating too much disruption. While it’s normal to catch your furnace making noise as it starts up, other noises are indicating your furnace requires immediate professional help.

Here are some of the most frequent furnace noises and what they might mean. If your furnace is making an atypical noise, our friendly heating pros are here to fix the problem with the best furnace repair in Richmond, British Columbia.

1. Furnace Makes a Banging Sound

You might have a critical 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 a couple of problems. These involve gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes dirty as time passes, so that’s why it’s critical to set annual furnace maintenance with Refrigeration Systems Ltd.. One of the tasks our pros do during this appointment is clean your furnace’s burners. When this piece gets dirty, you might hear your furnace making a loud rumbling noise if ignition takes more time. The subsequent gas buildup may break your furnace’s heat exchanger, where natural gas transforms into heat. Any breaks in it can leak carbon monoxide, which is ordinarily vented away from your home. This dangerous gas can be fatal 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 reaching us at 778-693-2532. Too much natural gas in your furnace or a fractured heat exchanger are dangerous issues that require prompt service.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to provide heated air throughout your house. If the ductwork wasn’t installed correctly or is getting dated, it can be loud when your furnace is heating. This may 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 pinpoint 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 often means there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace depends on 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 moves warm or chilly air throughout your space, and a capacitor, which turns on the motor. If either of these components are failing, they will buzz when the furnace switches on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it can be the result of something small, like a loose screw, or something critical, like a broken component. In either case, we urge you to shut your furnace off and getting in touch with our heating specialists at 778-693-2532 for support.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to alert you it needs some TLC. If you’ve forgotten furnace maintenance recently, belts could be worn out or a bearing might need to be greased. We know that maintenance sometimes slips your mind, but our professionals can get your furnace heating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re detecting your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You could also hear whistling while the furnace is running if a floor vent isn’t tight. If you’ve checked your vents but are still hearing sound, Refrigeration Systems Ltd. can assist you. It’s critical to get loose ductwork repaired quickly, as it can result in comfort issues in your home and increase your heating costs.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal racket frequently means there’s trouble with your furnace’s blower. Turn off your furnace off immediately and contact us at 778-693-2532 for help.
