When your furnace is working like it should, it should give warmth without making too much disruption. While it’s normal to catch your furnace making noise as it turns on, other disruptions are indicating your furnace needs immediate professional assistance.

Here are some of the most frequent furnace noises and what they could mean. If your furnace is making a strange noise, our friendly heating professionals are here to help with the best furnace repair in Alice, Texas.

1. Furnace Making a Banging Noise

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

Banging Sounds Coming from Your Furnace

Your heating system turns filthy as time passes, so that’s why it’s essential to set seasonal furnace maintenance with Rescue Heating & Air. One of the tasks our professionals do during this service is clean your furnace’s burners. When this part gets grimy, you may hear your furnace making a loud rumbling noise when ignition takes longer than normal. The resulting gas buildup might fracture your furnace’s heat exchanger, where natural gas turns into warm air. Any fractures in it can discharge carbon monoxide, which is regularly released outdoors. This hazardous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Rescue Heating & Air advises turning it off and contacting us at 361-265-4371. Too much natural gas in your furnace or a ruptured heat exchanger are hazardous issues that necessitate immediate service.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to deliver heated air across your house. If the ductwork wasn’t put in properly or is aging, it can make a lot of noise when your furnace is on. This may be the problem if your furnace makes a banging noise when it shuts off. Get in touch with Rescue Heating & Air at 361-265-4371 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace depends on an internal transformer to operate on the correct voltage. If wires or the box isn’t tight enough, you could detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which distributes heated or chilly air across your rooms, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace turns on.

3. Furnace Making a Rattling Noise

If your furnace is making a rattling noise, it can be the result of something small, like a loose screw, or something critical, like a broken part. In either case, we recommend shutting off your furnace and calling our heating professionals at 361-265-4371 for assistance.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to get your attention it needs some TLC. If you’ve neglected furnace maintenance the past few years, belts could be worn out or a bearing might need to be greased. We realize that maintenance sometimes slips your mind, but our techs can get your furnace operating quietly again quickly.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s frequently due to an air leak in your ductwork. You could also notice whistling while the furnace is operating if a floor vent is loose. If you’ve checked your vents but are still noticing noise, Rescue Heating & Air can help. It’s critical to get loose ductwork repaired without delay, as it can result in comfort issues in your home and drive up your energy bills.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you detect your furnace making a grinding noise. This metal-on-metal sound often means there’s trouble with your furnace’s blower. Shut down your furnace off right away and contact us at 361-265-4371 for help.
