When our heater turns on it makes a loud sort of electric humming buzzing sound. The sound is very noticeable and distinct. It is an intertherm unit.

Anyone out there specialize in heating/cooling?

What would make this thing be so damn loud? Would I be able to fix it myself or is it going to cost an arm, leg and kidney?

draw down and do a double tap

I would say call a pro but their probably is one here.

Is it an electric unit or gas?

If electric it sounds like a sequencer or it could be a fan relay.

If it is gas it could be a fan relay.

If it has a control module (board) on it then it could be something on it making the noise.

Could be the 240 to 24 volt transformer. Try giving it a tap with something non metalic. Or it could just be loose mounting screws.

Sounds like a contactor buzzing. SOme contactors have rubber pads to keep them from doing that and they deterorate over time. You need to pull the covers off and try & locate the source of the noise first, then go from there.
