I'm going to be in heaven on Earth, today. Going to clean a condensor. Got
the call yesterday, fellow was out of town for a few days, came home to find
his central AC not running. Some trouble shooting reveals a bad contactor.
With the contactor replaced, the unit does run. But barely. Superheat is a
bit low, and the refrigerant coming to the evaporator is noticably warmer
than ambient.

I'm replacing a 30-year old natural gas furnace and air conditioner
this fall. Does anyone have any experience with the Steffes ETS
product line? It looks like I can replace my current system with a
central unit that stores heat during the night with half price
electricity between 11:00 pm and 7:00 am. It uses my existing duct
system to distribute the heat. Coupled with a heat pump for the warmer
"cold" days it is supposed to be pretty effective.
I live in the Twin Cities metro area of Minnesota so the system needs
to work. Most of the big HVAC outfits in the metro area don't carry
the product line so I'm left with smaller companies from the outlying
towns. I'm thinking that may be an advantage.
Thanks.

This is in Arizona.
The other day I was in my attic to lay some cat5 and noticed the ac
lines in the attic running from the outside unit to the indoor part do
not have any insulation on it. The line outside form the outside unit
to the wall of the house do have insulation around it.
The attic gets quite toasty and I'd think it would be a good idea to
insulate them ? They are very easy to access.
What do you think ?
Also, the lines are hanging from one end to the other for quite a bit
of distance and not supported.
While I Was up there one of the units kicked in and I noticed the line
moving a little bit when the unit started.(then stopped moving, so
only moved caused by the start) Probably not good either ? What do I
use to hang it more secure ? The roof is a wood frame roof with tile
on top.
Well, Hope you hvac guru's can give me some advice,

There are a few older vehicles on the road running with R12. R134 is'nt a
great replacement, but are there any superior to R401a (dupont MP39) for
performance and changeover ease? I assume standard accumulators, expansion
valves, etc. are suitable for this. Is it mandatory to switch over to
alkylbenzene oil from mineral oil? 401a is not cheap. Is the cost difference
from R12 too little to justify the possible additional labor?
