Arrived to do a maintenance on a carrier system vertical in closet. I cleaned and flushed the drain line with cleaner and water. I replaced the pan treatment in the drain pan per plan. I checked the electrical system. I changed the filter, 12x24x1, the uv light needs to be moved up in the coil or in the cabinet of air handler. It’s eating the filter. Needs to be ten inches from the filter. The duct work is old and the insulation on the ducts is flaking off and is loosing the r value. Would like to have a comfort adviser come out to give a quote for new duct work. The system is working good at this time. Thanks for using air now for all your air conditioning needs.
