    Evaporator coil.
    OK here is a qestion I have,if you replace a older R22 evaporator coil with a newer R410A Coil will you have to replace the out side condencer?if so can you just use 410a in a r22 system?

    # 2 question is: can you convert a stright cool air conditioner to a heat pmp by putting a reversing vave in it?

    I an just curious.:D

    Reply soon.

    No and no to both questions with various theoretical exceptions.

    You can replace the coil with a coil for R-410A but you will have to use R-22 and a expansion device for that refrigerant also.

    so can u just use 410a in a r22 system?

    NO the outside unit is only capable of using R-22.

    2 question is: can u convert a stright cool air conditioner to a heat pmp by putting a reversing vave in it?



    While it would be possible to just add a reversing valve most Heat pumps have a stronger built compressor. You would also have to add a defrost system etc so it would not be reasonable price wise to attempt it.

    Class over for today.
