Maintenance 2 Checked all system electrical components. All electrical within factory spec. System was showing low pressures due to a clogged filter. Pressures returned to correct levels after filter was removed. Found bio growth starting to grow in air Handler. I am recommending a pure x UV light system with and included cleaning of growth. This will remove and prevent any further growth. I am also recommending a surge protector for condenser unit as it is unprotected at this time. Cleared drain line to condensate pump. Cycled condensate pump to insure its proper operation. Homeowner will be returning to the area later this year and will contact us if he would like to move forward with the system cleaning and improvements. Left system draining and operating properly at this time.
