Hello all..
I work and live in Memphis,and My company has been installing 13seer
units,this year,Well it seems that we get alot of call backs that the
units are not cooling as well as the H/O old 30 year old 10 SEER
units..
Now I dont know if the installers are pulling vacuums or not,and I am
sure that the units are not charged by sub cooling either,So those are
a couple of factors to take into consideration.. It just seems that
these new 13 SEER units are over sensitive to hot return air,hot
outside tempratures,and proper freon charge..
Now on the older 10 SEER units,it seems that one could have a open
return in the attic,not pull a vacuum,and overcharge by 3 pounds,and
the thing would still cool the H/O's house down.. And these new 13 SEER
units,we have to lower the fan speeds,install TXV's on every last one
of them etc etc...
Basically I am just curious if any other service techs out there in
the HVAC world have had problems with these.. I have heard alot of
differnt things from other's,But not enough :P The new 13 SEER are
supposed to have the same capacity as the old 10 SEER,but have thinner
evaps etc.. Gonna stop here,untill I get a response for the question at
hand.... "Do they cool as well" ??
