I arrived at our clients home for concerns that the fresh air exterior vent was damaged. I first proceeded into the attic to verify the integrity of the duct and confirm it was secure. I then climbed onto the roof and found the exterior cap to be an exhaust cap that is meant to push air out. It was in a stuck open position, most likely caused by the heavy winds. I was able to take measurements and explained to Mr. Dowling that this was not the appropriate cap for the fresh air option. We discussed replacement options and Mr. Dowling elected to replace the cap as well as sign up for our maintenance agreement plan for 1 year. I will return Monday morning to preform the repair and complete the maintenance service at the same time.
