I agree most RV units are Junk!! my neighbor had a camper and I swear every year i had to go work on his Junk dometic rooftop air units....
and of course im sure everyone taking road trips has seen the shrouds laying along side the freeway that have blown off of rooftop units...
to build my own A/C I would sooner start with a PTAC than I would a window shaker... just because most of the mare 2 shaft 2 motor and some are even ductable...
Minisplits are great other than the massive outdoor unit size... hard to basement mount.. the indoor units on those are easy to take apart and modify.. (thats what I built my house A/C based on.. before VRV was even thought of for residential)..
Give me your thoughts on this one? I have been told that these units are screwed and can't be sold.
I still have access to 7 PTAC's that were special ordered from TRANE and yes I have talked to some of them and get the same answer cause I want to change them.
They were built for a job that spec'd 418? Not 408 or 460v
Ended up the corp of engineers couldn't provide that voltage either so all of the equipment for mechanical and elec. changed to 460 so my old company stored everything because TRANE didn't want them back.
I wanted a PTAC for my build?
Is it worth the money to convert one or two? Is it cheaper to find the correct voltage?
What would need to change? I know step down/up transformers are high dollar but what about changing compressors and capacitors for the proper voltage?
I can get 7 of them for almost nothing but don't know if/how to make them usable for us.?
Thanks for any ideas.
Or just tell me it ain't worth it?
