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" ??
