Upon my arrival in Del Valle, I found that the pressures are high indicating towards a restriction, found that the heat transfer media system is still pretty dirty, customer did try to clean some of it up since the last time we were out here. I also found that the thermostat was turning on the auxiliary heat strips which would cause the A/C system to not cool as well. I disconnected the emergency heat for now. Customer wants quotes for the cleaning and the thermal replacement and will consider it later down the road.
