When your furnace is running correctly, it should deliver warm air without creating too much disruption. While it’s normal to catch your furnace making noise as it begins running, other sounds are signaling your furnace requires immediate professional assistance.
Here are some of the most reported furnace noises and what they could be indicating. If your furnace is making a weird 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 could have an urgent situation on your hands if you’re noticing 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 include gas accumulating in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns grimy over the years, so that’s why it’s important to set annual furnace maintenance with Refrigeration Systems Ltd.. One of the tasks our pros perform during this work is clean your furnace’s burners. When this part gets grimy, you may hear your furnace making a loud rumbling noise when ignition takes longer than normal. The subsequent gas buildup can break your furnace’s heat exchanger, where natural gas transforms into heat. Any fractures in it can discharge carbon monoxide, which is ordinarily released outdoors. This dangerous gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Refrigeration Systems Ltd. advises turning it off and contacting us at 778-693-2532. Too much natural gas in your furnace or a fractured heat exchanger are serious issues that necessitate prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to move warm air around your house. If the ductwork wasn’t put in properly or is getting dated, it can make a lot of noise 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 pinpoint the problem.
2. Furnace Buzzes Constantly
If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace depends on an internal transformer to work on the correct 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 hot or cold air around your space, and a capacitor, which turns on the motor. If either of these components are fading, they will buzz when the furnace turns on.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it may be the result of something little, like an unsecure screw, or something serious, like a broken component. In either case, we recommend shutting off your furnace and contacting our heating specialists at 778-693-2532 for help.
4. Furnace Squeals
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to tell you it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be worn down or a bearing might need to be lubed. We realize that maintenance sometimes slips your mind, but our technicians can get your furnace running quietly again quickly.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re detecting your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You might also hear whistling while the furnace is operating if a floor vent is loose. If you’ve examined your vents but are still sensing sound, Refrigeration Systems Ltd. can provide support. It’s critical to get loose ductwork fixed fast, as it can result in comfort troubles in your residence and drive up your utility expenses.
6. Furnace Makes Noise that Sounds Like Scraping Metal
It’s not a positive sign if you hear your furnace making a grinding noise. This metal-on-metal racket typically means there’s a problem with your furnace’s blower. Switch off your furnace off promptly and call our pros at 778-693-2532 for assistance.
