    If both airhandler n outdoor unit are both 410.you would have to change the indoor metering device to match the outdoor unit.never seen a txv that could do both a blend n a refrigerant.keep in mind a mis-match system is not ari rated n for most manufactuer that will void warranty.

    That AHU is listed for R22 and comes with a R22 TXV.

    Attempting to connect an R22 coil (even if the TXV is changed) is a bad idea. It's almost impossible to flush all the mineral oil from the coil and that will result in reduced performance and equipment life.

    That will happen even if it's a listed ARI match. What you got will not be and therefore will carry no warranty.

    There's no shortcut to doing it right, but that will result in the best performance and least cost overall.

    If you're a homeowner attempting this, I highly suggest that you get a QUALIFIED pro and save yourself a lot of stress on your person and wallet. No competent pro would attempted this.

    Has the Comfortmaker A/H been in use? Or still in a box? There are many R-22 and 0r R410a TEV's meaning they will work with either refig. But are you sure you have one? The PD on that unit says it's a R-22 unit. If the A/H hasn't been used I would just change the TEV and go ahead and give it a whirl. Since you seem to be getting the " fell off the back of the truck " discount you don't have to worry about warranty anyway. And if that is the case and you attempt to get warrant parts you can expect a knock at the door.
