I just got a call about two lenox airconditoning units linesets was stolen today. So when I got there the theives had ruined both liquid and suction service valves. My question is it worth my time repalcing the service valves or confince the owner to just by 2 new units. The units are 10 seer I explain to the owner that I would have to change the a-coil because the new units would be a 13 seer. Well the owner is complaining about the price of replacement and just want the service valves replace. Should I do the job? or just walk away?
