Here are some of the most reported furnace noises and what they could be indicating. If your furnace is making a strange noise, our friendly heating professionals are here to assist with the best furnace repair in Bend, Oregon.

1. Furnace Makes a Banging Sound

You could have a serious situation on your hands if you’re detecting 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 building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty as time passes, so that’s why it’s important to set yearly furnace maintenance with Tri County Climate Control LLC. One of the things our techs do during this appointment is clean your furnace’s burners. When this part gets grubby, you could hear your furnace making a loud rumbling noise after ignition takes longer than normal. The subsequent gas buildup might crack your furnace’s heat exchanger, where natural gas turns into heat. Any breaks in it can emit carbon monoxide, which is ordinarily released outside. This toxic gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Tri County Climate Control LLC advises turning it off and contacting us at 541-238-2797. Excessive natural gas in your furnace or a cracked heat exchanger are dangerous problems that require fast attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver warm air around your house. If the ductwork wasn’t put in properly or is getting dated, it can be loud when your furnace runs. This can be the issue if your furnace makes a banging noise when it shuts off. Call Tri County Climate Control LLC at 541-238-2797 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often is telling you there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace depends on an internal transformer to run on the correct voltage. If wires or the box needs to be tightened, you may hear a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes hot or cold air around your residence, and a capacitor, which turns on the motor. If either of these components are failing, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it may be the result of something small, like an unsecure screw, or something major, like a broken piece. In either case, we advise shutting your furnace off and contacting our heating pros at 541-238-2797 for help.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s trying to get your attention it could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn out or a bearing could need to be lubricated. We know that maintenance frequently slips your mind, but our technicians can get your furnace operating quietly again quickly.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s likely because of an air leak in your ductwork. You may 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 sound, Tri County Climate Control LLC can assist you. It’s important to get loose ductwork fixed without delay, since it can make comfort troubles in your residence and drive up your energy costs.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound frequently means there’s trouble with your furnace’s blower. Turn off your furnace off right away and contact us at 541-238-2797 for support.
