I have the chance of buying a used Lennox HS18-211-6P AC Condenser (in Toronto). I have been told that the unit is 2 ton and 4-5 yrs old. My question is this correct? (Info not on Lennox website). Also what things should I check/look for before I buy? The chap is allowing me to try the unit, if it doesn't work he will take it back. No A-Coil supplied though.
Any info/help is appreciated.
