If you are experiencing furnace troubles make sure you check your PVC Intake & Exhaust that is on the outside of the house.
With this much wind and snow, Drifts will build up in odd places.
I just had a call with a customer and I told him to check his pipes, I waited on the phone for 4 min's and he came back and was like " Hell yea it was blocked and now I have Heat "
So I saved the guy some $$$
There's going to be allot of calls like this today and the days to come.
Just a heads up

Your pipes should be this far from the ground, if they are not then Fix it
