Today I arrived and met with the homeowner. I completed the evaluation today of both units up and downstairs, began by verifying systems safety and its performance. I then flushed and treated the indoor water removal systems. I replaced the air filters today. While servicing the outdoor systems I cleaned the electrical cabinet and washed the units using water. I replaced outdoor voltage enhancement system for the upstairs unit under the 10yr pnl warranty. Upon departure customer did not want to approve or entertain any other options at this time.
