Hi there...
With the change in climate here in Eastern Ontario I have noticed two things:
When my furnace comes on I hear a banging type sound coming from the duct-work when the furnace first comes on. It lasts for maybe two or three minutes (I'm guessing until they heat up) and then it starts again after the furnace goes off. Same thing -- it seems after the furnace has been off for maybe two or three minutes it starts banging again. It lasts for at least ten minutes and again, I'm guessing it's the duct-work cooling back down.
Any thoughts? I'm no HVAC pro by any means, but this is the the best guess I can muster at this point.
So, here's what I need:
Advice on cause (If my diagnosis is wrong) A possible solution...?
Thanks a lot -- as you can imagine it's driving me mad and keeping me awake at night. Oh yeah -- the house is less than a year old also if that's relevant.
