Will Installing A TXV kit on Air Handler Solve Seer Rating Problem

by Courtney
(Henderson Nevada USA)

Will installation of a TEV or TXV kit on my air handler/ceiling fan coil solve the problem of my air handler with a SEER of 9 and my condenser unit with a SEER of 13/2.5 ton not being a matched system?

My neighbors have bought new condenser units but not bought new air handlers and the SEER ratings of these do not match up. Certain HVAC companies in town here are telling me that this will cause efficiency, capacity and life of the condenser unit problems down the line.

I hate to have to buy a whole new system for my 17 year old condo when I do not plan to be here more than a couple more years and the value has come down appreciably.

Seer rating
by: Chester

To get the true SEER rating out a system you must match the coil in the air handler to the condensing unit. It is best to use a TXV metering device in any system, but adding a TXV will not make your evaporator match your condenser. The new air handler with the proper coil will not be all that expensive and will pay for it's self in about 3 years with improved cost of operation.

Put in a new matched system, with a TXV and you should cut your cooling bill by about 25%

Installing TXV
by: Dadan

I really can’t tell you how the manufacture rates the TXV or it seer rating. All I know is seer rating is overall operating of the entire central ac unit. (It’s not accurate unit of measurement, but they decide to go with it.)

Yes, TXV is the best kind of expansion valve out there, but I doubt adding a TXV will increase the seer rating by 4! Manufacture have sheet of page tell you what unit seer rating goes with what.

Yes, opening the central ac unit will cause problem down the line, you open the central ac unit when there is no other option. Don’t do if you need to modify some part, it will cause you problem and money.

I hope I had answer your question.
