This heat!

[Ray]

500 square ft. per ton is normal. 400 sq. ft. per ton for higher effenciency.
The wife is retired. The husband works away from home all day.
After Rita, they went to a ridge cap instead of turbines. They have 6 inchs
of pink rolled in insulation. It is an older house, built around the same time
as mine.
They do have the older hard metal ducts. They do lose some effeciency
due to the heat and insulation in the attic. Filters are clean.
I have 3 turbine vents and they have a ridge cap vent system. My attic is
20 deg. cooler than theirs.
I have ceiling fans in 3 bedrooms, living room and kitchen. They have 3 total.
I also have 3 gable vents, they have a hip roof.
They have no kids at home.
The cool air coming out their vents is the same as the temps. coming out of mine.
My a/c is a 10 seer installed in 2003. Theirs is a 14 seer installed last year.
THe a/c puts out, the house is just not insulated like it should be, I guess. It is
putting out 55 to 58 degrees closer to the unit, but it is putting out 69 deg. at
the fartherst register from the unit. Looks like they are loosing some cool air due
to the metal ducts with old insulation in the hot attic.
