1. Furnace Makes Banging or Knocking Sounds

You might have a critical situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a few problems. These involve gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets filthy over the years, so that’s why it’s critical to set seasonal furnace maintenance with Refrigeration Systems Ltd.. One of the things our pros perform during this work is clean your furnace’s burners. When this piece gets grubby, you might hear your furnace making a loud rumbling noise when ignition takes longer than normal. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any cracks in it can emit carbon monoxide, which is ordinarily vented outdoors. This toxic 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 calling us at 778-693-2532. Significant natural gas in your furnace or a cracked heat exchanger are serious issues that necessitate immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to move warm air across your house. If the ductwork wasn’t designed properly or is getting dated, it can be noisy when your furnace is heating. This may be the issue 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 Buzzes Constantly

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound usually is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to run on the right voltage. If wires or the box is loose, you may hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves heated or cooled air throughout your house, and a capacitor, which turns on the motor. If either of these components are going out, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it could be due to something small, like a loose screw, or something major, like a broken piece. 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 Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to get your attention it requires some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing could need to be lubed. We realize that maintenance frequently slips your mind, but our techs can get your furnace operating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s frequently because of an air leak in your ductwork. You could also notice whistling while the furnace is working if a floor vent isn’t tight. If you’ve examined your vents but are still sensing whistling, Refrigeration Systems Ltd. can provide support. It’s critical to get loose ductwork fixed without delay, because it can create comfort issues in your residence and inflate your gas bills.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal sound frequently means there’s a problem with your furnace’s blower. Switch off your furnace off instantly and contact us at 778-693-2532 for support.
