MPdesign Posted May 3, 2010 Report Share Posted May 3, 2010 If I replace an old R-22 condensing unit outside, do I really need to replace the entire inside fan coil unit? I am aware of the concerns for efficiency and variable speed; but I have some customers that will reject that and just say that they want to replace the outside unit and not the inside unit because they have 10 of them and they all have another 10 years of life. Realistically I see 20+ year old fan coil units every day. I would like to hear a few opinions on this issue as it is a rather large issue for the industry.
