When your furnace is working correctly, it should give heat without creating too much noise. While it’s normal to catch your furnace making noise as it begins running, other disruptions are showing your furnace requires immediate professional assistance.

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

1. Furnace Making a Banging Noise

You could 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 might signal there could be several problems. These involve gas accumulating in your furnace or a ductwork situation.

Banging Sounds Coming from Your Furnace

Your heating system gets dirty over the years, so that’s why it’s critical to set annual furnace maintenance with JTech Mechanical. One of the things our technicians perform during this appointment is clean your furnace’s burners. When this part gets grimy, you might hear your furnace making a loud rumbling noise when ignition takes more time. The following gas buildup can fracture your furnace’s heat exchanger, where natural gas turns into warmth. Any cracks in it can leak carbon monoxide, which is ordinarily emitted outside. This hazardous gas can be deadly in large concentrations.

If you’re noticing banging or knocking sounds coming from your furnace, JTech Mechanical urges you to turn it off and contacting us at 281-231-8768. Significant natural gas in your furnace or a cracked heat exchanger are hazardous issues that require prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace works with ductwork to deliver warm air throughout your residence. If the ductwork wasn’t put in correctly or is getting old, it can be noisy when your furnace is on. This can be the problem if your furnace makes a banging noise when it shuts off. Call JTech Mechanical at 281-231-8768 and we’ll determine the problem.

2. Furnace Making a Buzzing Noise

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

Your furnace depends on an internal transformer to operate on the proper voltage. If wires or the box isn’t tight enough, you may notice a low humming noise in the furnace when off. Your furnace also uses a blower motor, which distributes hot or cold air around your rooms, and a capacitor, which triggers the motor. If either of these parts are going out, 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 can be related to something little, like a loose screw, or something serious, like a broken part. In either case, we advise shutting your furnace off and calling our heating pros at 281-231-8768 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s on, it’s making an effort to get your attention it needs some TLC. If you’ve neglected furnace maintenance recently, belts could be worn out or a bearing may need to be greased. We realize that maintenance often slips your mind, but our professionals can get your furnace heating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s typically because of an air leak in your ductwork. You might also notice whistling while the furnace is running if a floor vent is loose. If you’ve looked at your vents but are still hearing noise, JTech Mechanical can provide support. It’s critical to get loose ductwork taken care of quickly, as it can make comfort troubles in your home and inflate your utility expenses.

6. Furnace Making a Grinding Noise

It’s not an encouraging sign if you notice your furnace making a grinding noise. This metal-on-metal noise frequently means there’s trouble with your furnace’s blower. Turn off your furnace off promptly and contact our pros at 281-231-8768 for assistance.
