Came in to check why upstairs was not cooling, filter was clogged and when I took it out to check airflow at vents I could feel the co,d airflowing strongly. Replaced with 1 inch filters at return grilles Customer declined work for April aire filter replacement and will replace himself Went outside to check pressures and refrigerant levels are perfect Capacitors are working great they are in tolerance Went ahead and checked older machine and turns out it is overamping by 6 amps and recommend compressor saver kit for older machine
