Came to residence for prepaid WSC tune-up on a '14 ac system. Equipment functional upon arrival. Upon inspection of the indoor systems, I found the 16x25x1 filter was dirty and I replaced it with a homeowner provided filter. The blower wheel is starting to get dirty and should be cleaned in the next year or two. All other measurements and components are good. Moving outside, I found the condenser is operating well and the electrical and mechanical components are functioning correctly. All electrical measurements are within manufacturer specifications as well. See health report card for any specific information. Equipment functional upon departure. Thanks for your business and have a great day!
