When your furnace is working like it should, it should give heat without making too much sound. While it’s expected to hear your furnace making noise as it turns on, other sounds are signaling your furnace needs immediate professional support.
Here are some of the most common furnace noises and what they can mean. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Arlington, Washington.
1. Furnace Making a Banging Noise
You may have a serious situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a couple of problems. These involve gas increasing in your furnace or a ductwork issue.
Banging Sounds Coming from Your Furnace
Your heating system turns filthy over the years, so that’s why it’s critical to set seasonal furnace maintenance with Service Max Heating & Air Conditioning. One of the things our technicians perform during this work is clean your furnace’s burners. When this component gets grimy, you could hear your furnace making a loud rumbling noise if ignition takes more time. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas transforms into warmth. Any breaks in it can leak carbon monoxide, which is normally emitted outdoors. This hazardous gas can be fatal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Service Max Heating & Air Conditioning advises turning it off and calling us at 360-255-5857. Excessive natural gas in your furnace or a cracked heat exchanger are serious issues that require prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to provide hot air around your house. If the ductwork wasn’t put in right or is aging, it can be loud when your furnace is on. This can be the case if your furnace makes a banging noise when it shuts off. Call Service Max Heating & Air Conditioning at 360-255-5857 and we’ll figure out the problem.
2. Furnace Making a Buzzing Noise
If you observe your furnace making a buzzing noise, don’t delay calling us. A buzzing sound typically is telling you 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 isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends warm or chilly air throughout your house, and a capacitor, which turns on the motor. If either of these pieces are fading, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it can be related to something minor, like an unsecure screw, or something serious, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating professionals at 360-255-5857 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s attempting to alert you it could use some TLC. If you’ve skipped furnace maintenance the past few years, belts could be worn out or a bearing may need to be lubricated. We realize that maintenance sometimes slips your mind, but our pros can get your furnace running quietly again rapidly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s typically due to an air leak in your ductwork. You could also be aware of whistling while the furnace is working if a floor vent isn’t tight. If you’ve looked at your vents but are still noticing whistling, Service Max Heating & Air Conditioning can assist you. It’s important to get loose ductwork fixed fast, as it can result in comfort issues in your residence and drive up your heating 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 noise usually means there’s an issue with your furnace’s blower. Turn off your furnace off promptly and reach our professionals at 360-255-5857 for support.
