When your furnace is working like it should, it should give heat without generating too much disruption. While it’s common to notice your furnace making noise as it begins running, other sounds are showing your furnace should get immediate professional help.

Here are some of the most common furnace noises and what they might mean. If your furnace is making a strange noise, our friendly heating specialists are here to help with the best furnace repair in East Bernard, Texas.

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 indicate there could be a few problems. These include gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy as time passes, so that’s why it’s important to set routine furnace maintenance with E.B. Air. One of the tasks our professionals perform during this appointment is clean your furnace’s burners. When this component gets grubby, you may hear your furnace making a loud rumbling noise after ignition takes longer than normal. The subsequent gas buildup can crack your furnace’s heat exchanger, where natural gas turns into warm air. Any breaks in it can discharge carbon monoxide, which is normally vented away from your home. This toxic gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, E.B. Air recommends turning it off and calling us at 979-335-4262. Significant natural gas in your furnace or a cracked heat exchanger are critical troubles that require immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide warm air throughout your home. If the ductwork wasn’t designed correctly or is getting dated, it can be loud when your furnace runs. This could be the issue if your furnace makes a banging noise when it shuts off. Call E.B. Air at 979-335-4262 and we’ll determine the problem.

2. Furnace Buzzes Constantly

If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound often means there’s an electrical situation, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run 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 works with a blower motor, which moves warm 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 switches on.

3. Furnace Makes Rattling Sounds Like Something Is Loose

If your furnace is making a rattling noise, it could be due to something little, like an unsecure screw, or something serious, like a broken piece. In either case, we urge you to shut your furnace off and contacting our heating pros at 979-335-4262 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s going, it’s trying to get your attention it requires 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 lubed. We realize that maintenance frequently slips your mind, but our pros can get your furnace heating 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 working if a floor vent is loose. If you’ve checked your vents but are still hearing whistling, E.B. Air can help. It’s important to get loose ductwork repaired quickly, because it can create comfort issues in your house and drive up your heating bills.

6. Furnace Making a Grinding Noise

It’s not a positive sign if you notice your furnace making a grinding noise. This metal-on-metal sound usually means there’s trouble with your furnace’s blower. Shut down your furnace off promptly and reach us at 979-335-4262 for assistance.
