When your furnace is working correctly, it should give heat without making too much disruption. While it’s expected to hear your furnace making noise as it starts up, other disruptions are showing your furnace needs immediate professional support.
Here are some of the most common furnace noises and what they can be indicating. If your furnace is making a strange noise, our friendly heating professionals are here to assist with the best furnace repair in Genoa, IL.
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 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 dirty over the years, so that’s why it’s critical to book yearly furnace maintenance with Assured Appliance and Heating & Air. One of the jobs our techs do during this appointment is clean your furnace’s burners. When this piece gets grubby, you could hear your furnace making a loud rumbling noise after ignition takes longer than normal. The ensuing gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can emit carbon monoxide, which is normally released outdoors. This toxic gas can be lethal in large concentrations.
If you’re noticing banging or knocking sounds coming from your furnace, Assured Appliance and Heating & Air urges you to turn it off and contacting us at 847-306-8990. Excessive natural gas in your furnace or a ruptured heat exchanger are serious problems that require fast service.
Banging Sounds Coming from Your Ductwork
Your furnace works with ductwork to provide heated air throughout your residence. If the ductwork wasn’t designed correctly or is aging, it can be noisy when your furnace is heating. This could be the problem if your furnace makes a banging noise when it shuts off. Contact Assured Appliance and Heating & Air at 847-306-8990 and we’ll pinpoint the problem.
2. Furnace Making a Buzzing Noise
If you hear your furnace making a buzzing noise, don’t delay calling us. A buzzing sound frequently indicates an electrical situation, like with its transformer, blower motor or capacitor.
Your furnace uses an internal transformer to run on the right voltage. If wires or the box is loose, you might notice a low humming noise in the furnace when off. Your furnace also has a blower motor, which moves heated or cooled air throughout your rooms, and a capacitor, which starts the motor. If either of these parts are going out, they will buzz when the furnace switches on.
3. Furnace Making a Rattling Noise
If your furnace is making a rattling noise, it might be the result of something small, like a loose screw, or something serious, like a broken part. In either case, we urge you to shut your furnace off and getting in touch with our heating professionals at 847-306-8990 for help.
4. Furnace Making a Squealing Noise
If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to tell you it requires some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing could need to be greased. We know that maintenance sometimes slips your mind, but our techs can get your furnace operating quietly again rapidly.
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 might also hear whistling while the furnace is operating if a floor vent isn’t tight. If you’ve looked at your vents but are still sensing noise, Assured Appliance and Heating & Air can assist you. It’s important to get loose ductwork taken care of fast, since it can create comfort problems in your residence and drive up your heating expenses.
6. Furnace Making a Grinding Noise
It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal noise frequently means there’s a problem with your furnace’s blower. Turn off your furnace off promptly and call our professionals at 847-306-8990 for help.
