    Compressor Problem

    Just got back from site ,it was close to mmy house. Found half of the evaporator return bends and the suction line was froste up .Should I check restriction on distributor or just change the coil . Coil s rusted badly .It's about 10 years old. Since lt's a rental house ,changing the air handler is out of the question .

    Like to thank the members for their advices . Finally figure out the problem . Disconnect return duct from air handler ,found a thick layer of dirt inside the evp. coil .Clean it up ,start unit back up , pressures are good and indoor temp. drop eight degrees within an hour .

    Proper trouble-shooting sequence!

    That is why you should always follow a proper trouble-shooting sequence.

    With those symptoms, it is either an airflow evap heatload problem or, it is a refrigerant system problem. Always eliminate the airflow evap heatload situation, first. A proper system charge can never be achieved with an improperly heat-loaded evap coil.

    The blower wheel should have been checked, lint-filled blades, check underside of evap coil, clean coil, problem solved. - udarrell
