QUESTION:
I am getting a quote to check my system and possibly swap the piston to a txv and have a manual j done and come up with a best plan of attack. I was curious from someone in the field about how much cost reclaiming the r-22 and recharging the system, just a ballpark figure. The system is in the basement and there is nothing around the unit to be a pain to work around. Maybe I should just leave the piston alone but it seems that is my best alternative other than dropping a bunch of money on a higher seer system that I have no clue how much more efficient a 14-17 seer system is over a 13. Tempstar outdoor 13 seer ICP no name indoor unit but the coils match and the outdoor unit says to use size 70 piston. anything else you want model numbers etc I have just ask!

ANSWER: If the evaporator is a higher tonnage, make sure they use the 70 piston. If the E-Coil is a larger tonnage it will probably have been shipped with a larger than 70 piston orifice. It will not perform well with that kind of piston mismatch. Unless you live where there are a lot of hours of runtime per cooling season, it may not pay to replace the piston with a TXV metering device. Depending on your climate,a TXV can be better in many ways, so that is up to you. Figuring the cost, you will gain literally nothing spending money going to a higher SEER. Study the CA Research on EER & SEER Performance in CA. In What state & near which major city do you live?
