TXV - Thermal Expansion Valves

Thermostatic Expansion Valves can be mounted in any position on the evaporator coil inlet and are reliable, efficient and virtually trouble-free. Select the TXV to correspond with the tonnage of your air conditioner or heat pump, as well as to match the type of refrigerant your systems uses, R22 or R410A. They are required for 14 SEER or higher split system heat pumps, and an optional upgrade for other air conditioning systems.

Note: According to a california Energy Commision report, intalling TXV's in all systems would increase the seosonal efficiency 11%.
