Loud Rumbling Noise in Home

[rwang100]

Hi All,

Recently my home has started making loud rumbling noise like those from an engine. It isn't from my AC unit but I have no idea where this noise is coming from. Can anyone help me identify this noise?

Thanks

Need more info.

In the crawl space? Attic or where??

Is it water flow?? or only when the furnace is running?

Furnaces can make sounds when "off"

Check your thermostat and confirm the fan is set to auto and NOT ON!!
florecssnt light fixture??

What room is the sound strongest ?

OK find your broom handle or one of those painter handle extensions.. Use it like a hearing aid.. Put one end over the button of your ear and
go wherever the furnace is. Put one end on the sheet metal.
Is it louder?? This really works...

Go to a light fixture and hold it on the housing.. Does it hum louder??

write back what you find...
Is it your outside AC unit??

Maybe your cable box is one and the TV on and humming but the screen is dark.....[channel confusion]

Live near a fault line? Is something hungry

Kidding, like the previous post, could be a bunch of things. We don't know what other equipment may be in your home.
