My Gas Heater is Making Noise, Why?

Are you hearing knocking, clunking, and other loud noises coming from your gas heater? Don’t fret; we’re here to resolve it!

As a kid, you were afraid of things that went “bump” in the night, but as an adult, you hear a thump and you worry about a malfunctioning gas heater! Do you have a noisy gas heater? The expert technicians at QuickAir explain the reasons why your heater makes loud noise.

Here is a list of the alarming noises that your heater may be making;

• knocking
• Clanging
• Rattling
• Chirping
• Screeching
• Humming
• Bang or Boom

Here are the reasons why your gas heater is making noises;

1. Knocking

A consistent knocking sound: if that happens when the heater is on, is a sign that a heater repair technician must be contacted. The two most possible reasons for that knocking sound could be bad bearings, cracked belts, or damage.

2. Clanging

A clanging noise when your heater starts or just after it turns off might be caused by contraction and expansion. The metal pipes, vents, and other parts in the house generate banging and clanging noises as these parts get hotter and cool down. This is normal and doesn’t point to an alarming issue.

3. Rattling

A rattling sound caused by the heater could mean there is a loose panel and can be resolved by just tightening the screws on the cover panels. However, if you have examined the panels to ensure everything is screwed up, the rattling noise might be from contracting and expanding the metal parts of the heater as they change temperature. Still, if the rattling noise doesn’t stop, it may be something serious, and a gas heater repair expert must be contacted.

4. Chirping

A chirping sound from your heater usually occurs when your gas heater has not been in use for a long time and could just be an indicator that the heat is increasing. After the heater gets hot and runs for a few minutes, there will be no noise anymore. However, if the noise doesn’t stop and grows worse with time, a belt replacement can fix this noisy gas heater.

5. Screeching

If you hear screeching noises from your heater, it’s most probably because of problems involving the motor, bearing, or belt. Although this is not risky, if overlooked, it can cause major damage and require massive repairs later.

6. Humming

A humming sound from the heater starts by being easy to ignore. The blower motor usually makes this sound. If this is the situation, then you must turn off the motor and let it cool. When the temperature drops to a safe level, check the motor; the noise could be because of improper lubrication.
