Arrived on site to to perform spring tune up on 2 16 and 17 year old comfort maker. Client stated no issues as she doesn’t run unit’s much as they have Whole House fan that keep home cool. Cycled both units. Both condenser located out side. Downstairs on left and upstairs on right. Washed both condenser coil inside and out. Checked electrical compartment on both units. Both primary stater are okay show sign of wear due from condition and age. Both secondary motor controls are in range and have been replaced. Unit have had a compressor booster kit added on in past. Fan motor are both leaking a lot of oil in past and have been working hard. Advised due to the condo and bearing starting to seize up recommend replacing them. They are running but inefficient. Checked start up amps on compressor and both are good due to booster kit. Found run amps pulling high amps almost to max due to working hard and age. Checked pressure on both units and both units are holding a steady charge and goo
