Here are some of the most reported furnace noises and what they can be indicating. If your furnace is making a weird noise, our friendly heating specialists are here to assist with the best furnace repair in Warminster, Pennslyvania.
1. Furnace Making a Banging Noise
You might have a critical issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a few problems. These include gas increasing in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system turns dirty over time, so that’s why it’s important to schedule routine furnace maintenance with Retro HVAC Service & Installation. One of the things our techs perform during this work is clean your furnace’s burners. When this piece gets grubby, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The ensuing gas buildup can crack your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can leak carbon monoxide, which is normally vented outdoors. This toxic gas can be lethal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, Retro HVAC Service & Installation urges you to turn it off and calling us at 267-277-3851. Significant natural gas in your furnace or a ruptured heat exchanger are serious issues that necessitate fast attention.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to deliver hot air around your residence. If the ductwork wasn’t put in right or is aging, it can be noisy when your furnace is heating. This might be the issue if your furnace makes a banging noise when it shuts off. Get in touch with Retro HVAC Service & Installation at 267-277-3851 and we’ll determine the problem.
2. Furnace Buzzes Constantly
If you notice your furnace making a buzzing noise, don’t delay calling 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 operate on the correct voltage. If wires or the box isn’t tight enough, you could notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes warm or cold air throughout your space, and a capacitor, which triggers 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 due to something little, like a loose screw, or something serious, like a broken part. In either case, we urge you to shut your furnace off and calling our heating professionals at 267-277-3851 for assistance.
4. Furnace Making a Squealing Noise
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 skipped furnace maintenance recently, belts could be worn down or a bearing may need to be lubed. We realize that maintenance frequently slips your mind, but our professionals can get your furnace operating quietly again fast.
5. Furnace Makes a Whistling Sound Like Air Escaping
When you’re noticing your furnace making a whistling noise, it’s likely due to an air leak in your ductwork. You might also be aware of whistling while the furnace is operating if a floor vent isn’t secure. If you’ve checked your vents but are still noticing noise, Retro HVAC Service & Installation can assist you. It’s essential to get loose ductwork repaired fast, because it can result in comfort issues in your home and drive up your utility costs.
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 sound usually means there’s a problem with your furnace’s blower. Turn off your furnace off now and contact our professionals at 267-277-3851 for assistance.
