You guys aren't getting what I meant.
As far as evap and condenser I was wondering if they changed things like fins per inch, spacing between tubes etc
Engineering between the two will be close enough. Changing from one type of refrigerant to any other always requires the proper metering device for the refrigerant i.e. TXV at the head of the evaporator. Also, never reuse a dryer, get a similar sized new one. If you find the flushing solution expensive, remember, it's pretty much just Acetone anyway . HTH, Lefty71
