Today I showed up for a warranty tuna checked everything indoor and outdoor the only issues I have to report are the inrush amps approaching manufacturers limitations for the outdoor unit that outdoor unit is surrounded by overgrowth and the coils were severely restricted when I showed up I did wash the coils with water from the inside out however I recommend a deep thorough cleaning after they remove all of that overgrowth I flush the drain line with white vinegar it was flowing freely but looked a little slimy filters were pretty restricted but homeowner did not have new filters for me to change out today made recommendations discussed options homeowner chose not to take any recommendations today left unit running in cool mode
