All work to be done by licensed professional. WE KEEP GOING UNTIL YOU HAVE THE INFORMATION YOU NEED, I come and go. This is step ONE.

Hello, look this manual over and tell me if this is what you have, we can go from there

Find the bird screen., as shown on the air intake piping and make sure that is not clogged with debris

We can go from there until this resolves. the whoof sound is not entirely out of the normal. but lack of sufficient air could cause it to be worse
