TXV

Mastering HVAC Efficiency: Why the TXV (Thermostatic Expansion Valve) Matters Hot and cold spots, sticky indoor air, and rising energy bills often trace back to poor refrigerant control. The thermostatic expansion valve is the small part that makes a big difference. By metering refrigerant into the evaporator and holding a steady superheat, a TXV helps the coil absorb heat and moisture efficiently ...
