When your furnace is working properly, it should provide warm air without making too much sound. While it’s common to notice your furnace making noise as it starts up, other disruptions are indicating your furnace should get immediate professional assistance.

Here are some of the most common furnace noises and what they can be signaling. If your furnace is making an atypical noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Buellton, California.

1. Furnace Making a Banging Noise

You may have an urgent situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may indicate there could be several problems. These range from gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system gets grimy over the years, so that’s why it’s important to book routine furnace maintenance with Allstar Heating & Air Conditioning. One of the things our professionals do during this appointment is clean your furnace’s burners. When this component gets dirty, you may hear your furnace making a loud rumbling noise if ignition is delayed. The ensuing gas buildup might fracture your furnace’s heat exchanger, where natural gas changes into warmth. Any breaks in it can leak carbon monoxide, which is regularly vented away from your home. This dangerous gas can be deadly in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, Allstar Heating & Air Conditioning recommends turning it off and contacting us at 805-242-9638. Too much natural gas in your furnace or a fractured heat exchanger are serious problems that necessitate prompt attention.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide warm air throughout your house. If the ductwork wasn’t designed right or is getting dated, it can make a lot of noise when your furnace is heating. This could be the case if your furnace makes a banging noise when it shuts off. Contact Allstar Heating & Air Conditioning at 805-242-9638 and we’ll pinpoint the problem.

2. Furnace Buzzes Constantly

If you hear your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound frequently is telling you there’s an electrical issue, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to operate on the correct voltage. If wires or the box is loose, you might notice a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves hot or cold air across your residence, and a capacitor, which triggers the motor. If either of these pieces are going out, they will buzz when the furnace switches on.

3. Furnace Rattles

If your furnace is making a rattling noise, it could be the result of something minor, like a loose screw, or something critical, like a broken part. In either case, we advise shutting your furnace off and getting in touch with our heating pros at 805-242-9638 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s making an effort to tell you it requires some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn down or a bearing may need to be greased. We are aware that maintenance often slips your mind, but our techs can get your furnace heating quietly again fast.

5. Furnace Whistles

When you’re detecting your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also hear whistling while the furnace is working if a floor vent isn’t secure. If you’ve examined your vents but are still noticing sound, Allstar Heating & Air Conditioning can assist you. It’s critical to get loose ductwork repaired quickly, as it can result in comfort troubles in your house and inflate your utility expenses.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not an encouraging sign if you hear your furnace making a grinding noise. This metal-on-metal noise frequently means there’s trouble with your furnace’s blower. Shut down your furnace off instantly and call our professionals at 805-242-9638 for assistance.
