When your furnace is working properly, it should provide heat without making too much disruption. While it’s common to hear your furnace making noise as it starts up, other disruptions are signaling your furnace should get immediate professional support.
Here are some of the most reported furnace noises and what they might be indicating. If your furnace is making an odd noise, our friendly heating pros are here to help with the best furnace repair in Rockford, IL.
1. Furnace Making a Banging Noise
You may have an urgent situation on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it might signal there could be a few problems. These involve gas building up in your furnace or a ductwork problem.
Banging Sounds Coming from Your Furnace
Your heating system gets dirty over the years, so that’s why it’s critical to schedule seasonal furnace maintenance with Temperature Doctors Heating & Cooling, Inc. One of the things our techs perform during this appointment is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise when ignition takes more time. The following gas buildup may crack your furnace’s heat exchanger, where natural gas transforms into heat. Any cracks in it can discharge carbon monoxide, which is normally emitted away from your home. This dangerous gas can be deadly in large concentrations.
If you’re hearing banging or knocking sounds coming from your furnace, Temperature Doctors Heating & Cooling, Inc advises turning it off and calling us at (815)914-6197. Significant natural gas in your furnace or a fractured heat exchanger are serious issues that should get prompt service.
Banging Sounds Coming from Your Ductwork
Your furnace relies on ductwork to move hot air around your residence. If the ductwork wasn’t designed correctly or is aging, it can make a lot of noise when your furnace is on. This can be the case if your furnace makes a banging noise when it shuts off. Call Temperature Doctors Heating & Cooling, Inc at (815)914-6197 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound usually means there’s an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to operate on the right voltage. If wires or the box needs to be tightened, you may notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes warm or cooled air throughout your residence, and a capacitor, which turns on the motor. If either of these components are failing, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it may be the result of something little, like an unfastened screw, or something major, like a broken component. In either case, we recommend shutting off your furnace and calling our heating specialists at (815)914-6197 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to alert you it needs some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be greased. We realize that maintenance often slips your mind, but our professionals can get your furnace running quietly again quickly.
5. Furnace Making a Whistling Noise
When you’re detecting your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You may also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve checked your vents but are still noticing whistling, Temperature Doctors Heating & Cooling, Inc can assist you. It’s critical to get loose ductwork taken care of fast, since it can create comfort problems in your house and increase your heating costs.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal racket frequently means there’s a problem with your furnace’s blower. Turn off your furnace off right away and reach our pros at (815)914-6197 for assistance.
