Respond to LEA, MASTERMIND.

Later, I’ll show you how you approached this scenario, which is a terrific learning exercise.

“I was called by a customer that we installed a furnace in 2 years ago. She thought the bowing on her siding was from the furnace exhaust but said the dryer vent shows signs of bowing too ( under deck). Since her furnace was installed she had the roof redone and extra insulation added to the attic. I noted that it is unqualified to only 2 roof vents for this house. Since roof vents are sized at 1 per 240-300 sqft. Without measuring I would guess this house to be 1100 sqft. Raised bungalow. When the roof was done the old b vent chimney was removed, along with the old wirley bird. My question is would you do performance testing on this house? Do you have other concerns? Thanks in advance.”
