Upon arrival customer stated that system was not heating and no power was on for the system. After inspection of 8 year old system found that system had a failed transformer. Transformer failed from pressure switch wire touching copper. Blower wheel was dirty, zone system did not have its on transformer, system needed wet switch for drain pan, heat strips were not hooked up properly, outdoor condenser coils were very dirty, and drain line for condensation pump was not built correctly. Gave customer estimate to clean blower wheel, install a transformer for zone system and hvac system, clean condenser coils, add wet switch, blower motor capacitor, and fix drain line. Customer approved to have all repairs done. Made all repairs system, and unit is back up and running at this time.
