When your furnace is running properly, it should deliver warmth without generating too much sound. While it’s expected to hear your furnace making noise as it begins running, other disruptions are showing your furnace should get immediate professional assistance.

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 specialists are here to help with the best furnace repair in Alice, Texas.

1. Furnace Makes Banging or Knocking Sounds

You might have an urgent problem on your hands if you’re detecting your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a couple of problems. These involve gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system turns grimy as time passes, so that’s why it’s critical to schedule routine furnace maintenance with Rescue Heating & Air. One of the tasks our techs perform during this service is clean your furnace’s burners. When this piece gets grubby, you may hear your furnace making a loud rumbling noise when ignition takes longer than normal. The ensuing gas buildup might break your furnace’s heat exchanger, where natural gas transforms into warm air. Any fractures in it can leak carbon monoxide, which is regularly released outdoors. This dangerous gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, Rescue Heating & Air urges you to turn it off and contacting us at 361-265-4371. Significant natural gas in your furnace or a fractured heat exchanger are critical problems that necessitate immediate attention.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to provide heated air throughout your home. If the ductwork wasn’t installed properly or is getting dated, it can be noisy when your furnace is on. This might 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 Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t wait to call us. A buzzing sound frequently indicates an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace uses an internal transformer to work 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 moves hot or cooled air around your home, and a capacitor, which turns on the motor. If either of these parts are fading, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it can be the result of something little, like a loose screw, or something serious, 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 Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s trying to tell you it requires some TLC. If you’ve skipped furnace maintenance recently, belts could be worn down or a bearing could need to be lubricated. We are aware that maintenance often slips your mind, but our technicians can get your furnace heating quietly again rapidly.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re hearing your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You may also hear whistling while the furnace is running if a floor vent isn’t tight. If you’ve looked at your vents but are still sensing sound, Rescue Heating & Air can assist you. It’s important to get loose ductwork taken care of quickly, because it can make comfort problems in your home and increase your gas expenses.

6. Furnace Makes a Loud, Unpleasant Grinding Noise

It’s not an encouraging 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 now and call us at 361-265-4371 for help.
