4 Dangerous Heater Noises

Some of the unexpected cold fronts during the winter here in Houma might have you using your heater more than you thought. But is your heater ready to handle the cold temperatures and heat demands? You need reliable heater repair services to make sure your home stays warm throughout the season.

At Trahan’s Heating & Air Conditioning, we provide the best Houma heater repair. If you’ve ever thought to yourself, “Why does my heater sound so loud?”, then you’re in the right place. From harmless sounds that can be easily fixed to dangerous noises you should never ignore, we’ve got the answers to all of your heater concerns!

Banging, Clanking & Rattling In Your Heater

One of the most noticeable sounds that your HVAC or furnace could make is a loud banging sound. There is no normal function within your heating system that can be attributed to this jarring sound. In fact, the issue might be exactly what it sounds like: metal hitting other metal.

Inside your unit, there is a motor, fans and other moving parts that can be knocked loose. If you hear a clear movement inside your unit when it runs, there is likely a component loose. Don’t wait for the loose part to cause more damage inside the heater. Shut down your system and call for professional heater repair!

If you notice a bang every time your furnace starts, you could have a combustion problem as well. If the ignitor doesn’t turn on right away, gas can start to build up inside the combustion chamber. When the ignition does finally take place, it’s like a small explosion inside the furnace. This can put a strain on the system over time and lead to deadly malfunctions like a cracked heat exchanger.

Squealing Sound In Your Heater

If you can hear a high-pitched sound like squealing, you might have another kind of heater repair. Your heater’s blower could have ball bearings that are worn out, or it could be struggling to take in the proper amount of air. If the airflow is compromised, you might notice a whistling sound as well. This is likely the air struggling to bypass the obstacle. Some examples of obstacles include:

  • Clogged air filters
  • Obstructed air vents
  • Damaged air ducts

Heater Is Buzzing

When your heater runs, it’s normal to hear a low hum. However, if the hum gets disruptive or you notice a distinct buzzing sound, the problem is likely electrical. Any of the motors or transformers inside your unit could be causing this sound. One thing is for sure: you don’t want to mess around with an electrical heater repair yourself.

Always trust a professional to avoid any electrical risks in the future like fires.

Clicking Sounds From Heater

The primary source of clicking sounds in your furnace is a faulty or struggling ignition system. There are several reasons why an ignition system may not be working properly, including pilot light problems and broken sensors. Without ignition, your furnace can’t produce heat, so the best option is to call for expert heater repairs.
