Here are some of the most common furnace noises and what they could be indicating. If your furnace is making an atypical noise, our friendly heating pros are here to assist with the best furnace repair in Newton, Iowa.

1. Furnace Makes Banging or Knocking Sounds

You may have a serious issue on your hands if you’re hearing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be a couple of problems. These range from gas increasing in your furnace or a ductwork problem.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over time, so that’s why it’s important to set yearly furnace maintenance with Brookwood Inc. One of the tasks our professionals do during this work is clean your furnace’s burners. When this part gets dirty, you may hear your furnace making a loud rumbling noise after ignition takes longer than normal. The resulting gas buildup can break your furnace’s heat exchanger, where natural gas changes into heat. Any cracks in it can emit carbon monoxide, which is regularly emitted away from your home. This hazardous gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Brookwood Inc advises turning it off and reaching us at 641-316-9803. Excessive natural gas in your furnace or a ruptured heat exchanger are serious issues that should get prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver heated air around your residence. If the ductwork wasn’t put in properly or is getting dated, it can be noisy when your furnace is heating. This could be the issue if your furnace makes a banging noise when it shuts off. Contact Brookwood Inc at 641-316-9803 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you hear your furnace making a buzzing noise, don’t hesitate to call 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 correct voltage. If wires or the box is loose, you could hear a low humming noise in the furnace when off. Your furnace also uses a blower motor, which sends hot or cold air around your home, and a capacitor, which turns on the motor. If either of these pieces 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 related to something minor, like an unsecure screw, or something critical, like a broken piece. In either case, we urge you to shut your furnace off and calling our heating professionals at 641-316-9803 for support.

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 making an effort to tell you it requires some TLC. If you’ve neglected furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubricated. We are aware that maintenance frequently slips your mind, but our techs can get your furnace running quietly again quickly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re noticing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is running if a floor vent is loose. If you’ve checked your vents but are still noticing noise, Brookwood Inc can provide support. It’s important to get loose ductwork fixed without delay, as it can make comfort issues in your residence and increase your gas costs.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not a good sign if you hear 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 now and reach our professionals at 641-316-9803 for assistance.
