1. Furnace Making a Banging Noise
You might have a critical problem on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it might mean there could be a few problems. These range from gas building up 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 essential to book routine furnace maintenance with House of Heating Incorporated. One of the jobs our professionals perform during this appointment is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes more time. The subsequent gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can discharge carbon monoxide, which is regularly emitted away from your home. This dangerous gas can be deadly in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, House of Heating Incorporated advises turning it off and reaching us at 715-384-3163. Excessive natural gas in your furnace or a broken heat exchanger are dangerous troubles that should get prompt attention.
Banging Sounds Coming from Your Ductwork
Your furnace uses ductwork to deliver warm air around your home. If the ductwork wasn’t designed correctly or is aging, it can be loud when your furnace is heating. This may be the issue if your furnace makes a banging noise when it shuts off. Call House of Heating Incorporated at 715-384-3163 and we’ll figure out 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 usually indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to work on the right voltage. If wires or the box isn’t tight enough, you could hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends hot or cold air across your rooms, and a capacitor, which turns on the motor. If either of these components are fading, they will buzz when the furnace starts.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it might be related to something minor, like a loose screw, or something serious, like a broken component. In either case, we advise shutting your furnace off and contacting our heating professionals at 715-384-3163 for support.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to get your attention it could use some TLC. If you’ve neglected furnace maintenance recently, belts could be dilapidated or a bearing may need to be lubricated. 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 typically the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is running if a floor vent is loose. If you’ve looked at your vents but are still hearing noise, House of Heating Incorporated can help. It’s essential to get loose ductwork repaired without delay, because it can result in comfort troubles in your home 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 frequently means there’s trouble with your furnace’s blower. Turn off your furnace off now and reach our pros at 715-384-3163 for help.
