When your furnace is working like it should, it should provide warm air without generating too much disruption. While it’s normal to hear your furnace making noise as it starts up, other disruptions are showing your furnace should get immediate professional assistance.
Here are some of the most common furnace noises and what they can mean. If your furnace is making a strange noise, our friendly heating professionals are here to assist with the best furnace repair in Norton, Virginia.
1. Furnace Makes a Banging Sound
You may have an urgent issue on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can mean there could be a few problems. These involve gas accumulating in your furnace or a ductwork situation.
Banging Sounds Coming from Your Furnace
Your heating system gets grimy as time passes, so that’s why it’s important to set yearly furnace maintenance with HCE Systems. 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 after ignition is delayed. The ensuing gas buildup might crack your furnace’s heat exchanger, where natural gas transforms into heat. Any fractures in it can emit carbon monoxide, which is regularly emitted away from your home. This toxic gas can be fatal in large concentrations.
If you’re aware of banging or knocking sounds coming from your furnace, HCE Systems recommends turning it off and contacting us at 276-302-0076. Excessive natural gas in your furnace or a fractured heat exchanger are serious problems that require fast service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to move warm air around your residence. If the ductwork wasn’t put in right or is getting dated, it can make a lot of noise when your furnace is on. This may be the problem if your furnace makes a banging noise when it shuts off. Call HCE Systems at 276-302-0076 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 frequently indicates an electrical issue, like with its transformer, blower motor or capacitor.
Your furnace relies on an internal transformer to run on the proper voltage. If wires or the box isn’t tight enough, you might hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes warm or cold air around your rooms, and a capacitor, which starts the motor. If either of these pieces are fading, they will buzz when the furnace switches on.
3. Furnace Makes Rattling Sounds Like Something Is Loose
If your furnace is making a rattling noise, it may be due to something little, like an unfastened screw, or something critical, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating professionals at 276-302-0076 for assistance.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s attempting to tell you it requires some TLC. If you’ve neglected furnace maintenance recently, belts could be worn down or a bearing could need to be greased. We know that maintenance sometimes slips your mind, but our technicians can get your furnace running 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 could also be aware of whistling while the furnace is working if a floor vent is loose. If you’ve looked at your vents but are still sensing sound, HCE Systems can assist you. It’s essential to get loose ductwork repaired fast, since it can result in comfort issues in your house and drive up your utility bills.
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 noise usually means there’s an issue with your furnace’s blower. Shut down your furnace off now and call our professionals at 276-302-0076 for assistance.
