When your furnace is working properly, it should give heat without generating too much noise. While it’s normal to hear your furnace making noise as it starts up, other disruptions are signaling your furnace needs immediate professional help.

Here are some of the most reported furnace noises and what they could be signaling. If your furnace is making a weird noise, our friendly heating professionals are here to help with the best furnace repair in Ames, Iowa.

1. Furnace Makes a Banging Sound

You could 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 can signal there could be several 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 essential to book seasonal furnace maintenance with Haselhoff Air Solutions. One of the tasks our professionals perform during this work is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup might break your furnace’s heat exchanger, where natural gas turns into warmth. Any breaks in it can discharge carbon monoxide, which is regularly emitted outdoors. This toxic gas can be fatal in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Haselhoff Air Solutions recommends turning it off and reaching us at 515-450-8739. Significant natural gas in your furnace or a cracked heat exchanger are serious problems that require fast repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver hot air around your residence. If the ductwork wasn’t designed right or is aging, it can make a lot of noise when your furnace is heating. This can be the case if your furnace makes a banging noise when it shuts off. Get in touch with Haselhoff Air Solutions at 515-450-8739 and we’ll pinpoint the problem.

2. Furnace Makes a Buzzing Sound

If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound usually means there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the right voltage. If wires or the box is loose, you may detect a low humming noise in the furnace when off. Your furnace also uses a blower motor, which moves warm or cold air throughout your space, and a capacitor, which starts the motor. If either of these components are failing, 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 can be the result of something minor, like an unsecure screw, or something major, like a broken component. In either case, we urge you to shut your furnace off and contacting our heating professionals at 515-450-8739 for help.

4. Furnace Squeals

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s making an effort to tell you it requires some TLC. If you’ve skipped furnace maintenance the last couple of years, belts could be worn out or a bearing might need to be greased. We are aware that maintenance sometimes slips your mind, but our technicians can get your furnace operating quietly again rapidly.

5. Furnace Whistles

When you’re hearing your furnace making a whistling noise, it’s likely the result of an air leak in your ductwork. You could also be aware of whistling while the furnace is on if a floor vent isn’t secure. If you’ve looked at your vents but are still hearing noise, Haselhoff Air Solutions can assist you. It’s critical to get loose ductwork repaired without delay, because it can create comfort troubles in your house and drive up your utility expenses.

6. Furnace Making a Grinding Noise

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket typically means there’s a problem with your furnace’s blower. Shut down your furnace off promptly and call us at 515-450-8739 for assistance.

When you’re getting an uncommon noise from your furnace, Haselhoff Air Solutions is here to help. Contact us at 515-450-8739 to request your furnace repair appointment right away.
