Tech arrived to perform one time maintenance on system in home. System is zoned between upstairs and downstairs. Unit in attic had water in pan and single flood pan safety didn’t trip system. Made customer aware and presented options. Customer agreed to HomeCare plan paid in full, wet switch, SS2 safety switch and condensate drain line flush. Unclogged line, added union, clean out, and flushed line with cleaner and bacterial solution. Verified no more restrictions. Added SS2 and wet switch in series with flood pan safety and verified operations. Removed as much bacteria in evaporator coil pan as possible. Once cleaned. Tested heat. Heating operations are verified. Tested cooling. Cooling operations are verified. Drain line is draining. Outdoor unit is dirty and in need of cleaning in future. System is operational at techs departure. Thank you for letting TE Certified service your home.
