The first Pic shows the entry into the attic I wonder how many large HI’S or should I say fat HI’S would have disclaimed this entry hole as being to small. Once into the attic the hot water heater vent disconnected and within 4 feet of the open return air vent.:roll:
When I arrived this morning the A/C unit was turned off and the inside temp was above 80 I let the A/C unit run while I made my outside rounds and the roof. I had just felt of the suction line while outside and knew that there was a problem because the suction line felt to warm to me even on a warm house.
After running the A/C for approximately 45 minutes the inside temp fell to 76 but the supply was only reading 70. My mind was churning telling me that the return in the attic had to be open and sure enough that is what I found.
There were also 3 supply ducts under the home that were disconnected cooling the crawl space.
This was probally the worst abortion that I have inspected in a while. So many issues it will take a book to write. Furnace was installed in a bedroom closet with improper combustion air. Had to unscrew the closet wall to locate the furnace. The condensate was dripping out of the bottom of the furnace supply air plenum under the home. No ridge gas pipe into furnace cabinet. The supply plenum was constructed around a gas and domestic water supply piping.
