I performed a single system maintenance on a 2009 R22 gas system. I checked amps, capacitor, filter, drains, electrical, cleanliness, and safeties. I found the ground wire for the blower motor not hooked up and a couple of loose connections on the control board. I secured the ground wire and tightened the loose connections. I noticed the unit has a 15 degree temperature drop. I informed the customer that I believe this unit has 2 years left at best. The duct work has a responsible amount of dust contributory the dirty blower motor. I advised that these should be cleaned to remove stress from the system. The customer would like to make it through summer before considering replacement. I noticed that the contactor wasn’t in the best condition, the unit had an unnecessary fan motor capacitor, and that the unit was starting with higher amps. I priced duct cleaning for the customer, installed a 2 pole contactor, and offered a hard start kit. The system is performing to the best of its abili
