Halloween is over. What’s with the sounds coming from your gas furnace? Don’t be scared to ask for help. If you hear scary or funny noises coming from your gas furnace, it may be time to call in the professionals from Estes Services. They’re available to inspect it and determine if needs service, repair, or replacement.
When Gas Furnaces Go Bump in the Night
Normal operation involves minor pops and humming from your HVAC system. Here are some examples of noises you shouldn’t ignore.
Metal Scraping or Rumbling Sound
Apologies in advance for mentioning nails on a chalkboard. If you hear a sound resembling it, however, you may have a problem with your blower wheel. The metal scraping sound can be jarring and hard to miss.
A low rumbling sound, on the other hand, suggests a problem with the burner. In this case, it’s best to turn off the furnace and call a gas furnace pro from Estes Services.
An even, low humming is normal. If, however, the sound you hear is loud and different than the normal operation sounds, you may have a malfunction with your fan or capacitor.
Pop! Bang! Bam!
A common noise with a gas furnace, a bang or pop could come from the air ducts. When hot air passes through the cold metal, they expand and contract with the temperature change.
A delay in the ignition from dirty burners could also be the source. When burners are dirty, released gas accumulates. Once the ignitor produces the flame, the ignited gas creates a miniature explosion.
This pop is louder than the normal expansion and contraction noises. Worst case, you end up with a cracked heat exchanger. To fix this, your Estes pro cleans the furnace burners so there’s no gas buildup, and they light instantly.
Thumps and Bumps
Just like an unbalanced load in the washing machine, your gas furnace may make a thumping or vibrating sound. This is probably due to an unbalanced blower wheel, or even an unbalanced motor.
This is a serious situation and requires an HVAC pro to intervene. If neglected, an unbalanced wheel could permanently damage your system.
This is a common noise when there’s a problem with your gas furnace. The most likely culprits are 1) a loose blower belt, 2) a dry shaft bearing, or 3) a malfunctioning blower motor.
Do not ignore these. If left alone, they will disable your gas furnace. Call Estes Services to come and adjust, oil, replace, or repair the offending component.
