Roof or basement AC
I am window shopping PT buses. I noticed the first two ads on the bill
board are both for 36 PT's. One talkes about roof ac and the other talkes about basement ac.s, The newer one says roof ac. I would have thought them the same. I thought all the PT's had the basement AC. John Heckman central Pa 1973 FC |

Roof or basement AC
At least in the mid-80's I believe basement AC was standard and roof AC was an option. Our 84 PT-40 has 3 roof AC units.

Three roof A/C's on my 86 PT38.
I have no experience with basement A/C's, but conceptually I prefer the roof units...easy to work on and relatively easy/cheap to replace of it goes out.

Roof or basement AC
There are many PTs in the mid-80s that offered either "cruise air"
basement ACs or roof mounted ACs (usually by Duo-therm). Arguments can be made for either. The basement ACs offer less roof clutter and are potentially quieter inside the coach than the roof-top units. Roof ACs don't take up space in the basement and are easier to service and/or replace. To the best of my knowledge, both systems are ducted so run through air vents throughout the coach (although my knowledge of the earlier 80's era BBs is limited). One argument is that the cruise air units draw their input air from near the "hot pavement" and that the roof top units get "cooler" air from above. I don't know if this really makes much of a difference in actual practice. From my view, the biggest issue would be the loss of basement storage space with the cruise air. Beyond that, it's mostly a matter of personal preference. Pete Masterson '95 Blue Bird Wanderlodge WBDA 42 aeonix1@...

I'm in the process of changing out the original DuoTherms with DuoTherm Low Profile Penguin units. I've got everything purchased, one replaced, two to go....been on the go too much to get the rest done. Will get it done soon when I slow down a little. Doing the labor myself, the total cost will be $1200 for all three. From what I've been reading, the basement units have a higher maintenance costs. But, I also realize they are probably a little quiter. The three original A/Cs were all working but the front one started acting up. With their age, I decided to invest in new units to maintain reliability. The last thing I want if for the DW and kids to sweat on vacation! The old units are about 15" high. The new units are only 9" high. They just barely peek above the goat rail. Regards, Glenn Glenn & Lisa 1986 PT-40 Marietta, GA |

Roof or basement AC
My units are not ducted other than one small duct from the bedroom
unit into the bathroom. It has never been a problem, all three units on high and you can hang meat in there on a hot day.

Roof or basement AC
My bus came with both.
When running down the road, we start the genset,close off half the bus and run with the roof air. It is not ducted like the cruise airs are. Can't run the cruise air's while driving since they get their air from underneath and don't fair well when road is hot. Roof air cools front of bus fine. Don't like using the roof air when parked if we want to use tv as to noisy for my poor hearing. Start the front cruise air and can hear fine. For us, both have their uses.
