Are the TXV valves already installed on the GSXH5?

TXVs are not already installed the GSXH5 condensers. They will need to be purchased separately unless you are purchasing an evaporator coil or air handler with one built-in. For Goodman-brand coils and air handlers, the the coils and air handlers with a TXV built-in will have a "T" in the 4th character position in their model numbers.

If you have any further questions, please call us and we will be happy to assist you.
