13 SEER Splits not cooling!??!

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

Yup! Check air flow, before anything else!
