Completed tuneup on system, found tons of biological growth on the indoor unit and coil recommend a cleaning of the evaporator coil and air handler case and installing an IAQ 300 to help prevent future biological growth or also a cleaning in a regular UV light to combat that growth. Also talk to homeowner about hot rooms originally there is metal ductwork up in the attic that was tapped into by flex duct and is poorly designed. There is also no safety switch in case drain backs up to shut system off upon inspection of outdoor unit found that dogs have been urinating on condenser coil, causing it to shred a part on the corners cleaned the coil the best I could, and to not cause damage did not wash affected area Recommended a new condenser coil while still in warranty, but all electronics are within manufacture spec as far as just noticing for the heat strips has only one leg of the heat strips are hooked up.
