    Will all the new legislation being handed down cause everything to use a TXV or EXV ?

    Most likely not. 15 SEER with pistons has already been achieved, and coil/fin developments with 410A look good with pistons also.

    But only time will tell for sure.

    Humid areas will almost have to use txv's, to control humidity.

    How many times must one fix something before it is fixed?

    Piston, or fixed metering devices may still be around even in higher SEER systems, but TXV systems will still be better in areas where heat and humidity remain a problem.

    I know some of the grand-aire systems I have installed used pistons up to 14 seer.
    Please step AWAY from the condensing unit.

    Hey Gillman, What's a Grand-Aire???


    Shouldn't you be installing "Gillman-Aire"?

    tain't the make believe numbers, its the actual performance that counts. TXV's only make since. Everything else is about cheap and easy.
    "That's good enough..." usually isn't.

    But if cheap and easy works, there will always be someone doing it, right?

    Unless you even larger coils you better hope for txvs because in order to meet minimum efficiencies you have to enlarge the coil more for a piston.

    So whats the cost of a larger coil? Well obviously more material. Oh and heavier, and less on a truck, and more refrigerant, and tougher matches when it comes to hp's and poorer (is that a word) latent capacities and, difficult retrofit, the list goes on. Who's going to pay for all that stuff? An OEM TXV will probably allow the minimum efficiency at a lower cost in the long haul but hey if your hung on just the price of the part then so be it but ultimately it will not cost less but more.
