my house is cooling good there is also water on floor where evap coil is located the coil and filters are clean just had the fan and fan motor replaced
Answer by Polar Bear
The sure way to ascertain that an evaporator coil has gone bad is if it develops a leak and will not hold refrigerant, corrodes badly enough to prevent heat transfer through it or gets so dirty that it just simply blocks air completely (from neglect).
I’d say if you have water in the vent grilles your evaporator is working nicely….. that means the unit is cooling the surface down below the dew point. What you have is a duct work insulation problem or an outside air infiltration problem….
(ed) it sounds like when the fan was replaced the tech somehow modified or manipulated the condensate drain to drain wrong….. that could be a real problem in the future. Get in there and check it out….
