-CFM output was increased on thermostat, air flow is much stronger -Also, there was a 1â€ filter in place while there is a 5â€ merv 16 filter, which was hindering air flow as well -Surge protection was installed at the condenser as there is a lot of black outs and brown outs in the area
Upon arrival system was not operational. System is 21 years old and has had a couple repairs done to it. Testing found the capacitor had failed. Inspected fuses and they are were hot to the touch. Installed new capacitor and tested motor amps. They were almost at max and the compressor is in danger of failing. Went into attic and inspected indoor unit. System is not on a proper platform and is just resting on 2x4s. There is no emergency drain pan installed and the condensate lines are tied together. System is a 5 ton unit running on 3 tons of ducting. Extremely inefficient. Made repair options and talked about replacement. Clients went forward with repairs. Clients are aware of the condition of the unit and that this isnâ€™t a long term repair. This repair is to buy more time before either replacing the compressor or system. Clients moved forward with maintenance program. Unit is operational upon departure.
Upon arrival performed maintenance on 3 year old xc25. System is running very efficient. Need some more air flow adjustments to ducting. Install to come out. Recommended adding surge protectors for high Efficiency system. Circuit boards & electrical connections in range. Refrigerant and temp splits good. Washed out coils completely. Dusted off electrical. Electrical fuses in range. Thermostat in working order. System is operational.

Performed maintenance on a Lennox XC25. Systems cooling split is 20 degrees. Compressor and fan amps are in range. Outdoor coils were dirty, they were chemically cleaned today. Condensate lines are clear and free from debris. System is equipped with a merv rack. Filter was very dirty and also changed out with a new filter today as well. Duct runs are free from obstruction and sealed. System is not protected. System was cycled before departure
