it all depends on the system, and the load requirements of the system,,, they have to be perfectly matched.
and it just goes on the liquid line(coming from the condenser) right before the evaporator. then you take the sensing bulb and put it on the suction line leading out from the evaporator.... not to hard once you have all the right parts...

The phial of a thermostatic expansion valve is typically positioned on the suction line downstream of the evaporator coil. It is important for the phial to be securely clamped to the suction line to accurately sense the temperature of the refrigerant leaving the evaporator.
Thermostatic expansion valve consists of a thermal sensing element that regulates the flow of liquid refrigerant into an evaporator based on the temperature of the refrigerant returning from the evaporator.
If the evaporator pressure does not change when heat is added or removed from the thermostatic expansion valve bulb, the problem may be due to a malfunctioning thermostatic expansion valve itself, which could be stuck or blocked. Additionally, issues such as low refrigerant levels or a refrigerant leak can also prevent pressure changes. Lastly, a faulty bulb sensing element or improper bulb placement may hinder the valve's ability to respond to temperature changes effectively.
typical prices are from $725-$1500 for thermostatic expansion valve replacement
