Aaron Curry performed replacement of Limit switch and ran the HVAC and checked for any abnormalities. He also performed a preventative check on AC. He gave a clean chit to HVAC and AC. Appreciate his thoroughness. Dor-Mar Operations and Sales team could be more customer oriented and try to understand issues from customer perspective. They also need to revisit their policy of charging the customer, a labour charge every time they visit a unit even if it is a resolution of one single incident through two visits (one for diagnosis and one for replacement of a faulty item.)
