its look like blower problem , 1st check blower speed controller, check blower motor , check its ball bearing etc , its does not have any link to external unit .

on a call for air conditioning your therrmastat brings the indoor fan on and the out door unit at the same time. Since your fan comes on in "fan" mode, it sounds like you need a thermastat. For temp. cooling just turn your fan switch to "on" and turn system switch to cool and set desired temp. System will cycle off and on but fan will not shut off until fan control is set back to "auto". I suggest replaceing thermastat

most like it the motor windings are burn and you need to replace the blower motor

check capicitor on motor, fan motor bearings may be locking up when they get hot then when cooled the motor comes back on. Then you must replace fan motor.

Your AC cooling efficiency is low when he ambient temperature is high and naturally it cools well when the outside temperature drops.

Please remove the filter on the grill and try to clean it under the tap water and after removing all the dust fix it back to the unit. This would increase the cooling efficiency of the unit.

Your AC is also five years old. Please avoid frequent opening of doors or windows.

Ensure that the exhaust fan and the blower of your unit are functioning normal.

The technician might not have done a proper job in fixing the area where the refrigerant would have leaked out. Please check the refrigerant pressure to ensure that no further refrigerant leak has taken place. Or even servicing your unit he would have punchered the tubes resulting in very slow leak of refrigerant resulting in no cooling or less cooling. It takes around a month to feel the pinch of it and the refrigerant. One fine morning after sometime the unit will run and it would start throwing hot air instead of cool breeze!

Is the outside unit running? Fan and compressor?

The first problem sounds like the wiring is wrong up at the heating unit not turning on the blower fan in the heater when you call for cooling. Most typical is either something has chewed the wires or the wires have been stripped b something else. The AC not cooling your house can be either it is low on freon or the system is to small for your house. Also check your filter and make sure that it is not blocked and everything is clean with the filter

DOES THE HOUSE FEEL DRIER IF IT IS 80 OUTSIDE WITH ALOT OF HUMIDITY THE UNIT WILL RUN FOR A LONG TIME TO REMOVE THE MOISTURE(HUMIDITY) OUT OF THE HOUSE BEFORE TEMP DROPS DRAMATICALLY IS THERE WATER COMING OUT OF THE DRAIN PIPE OUTSIDE

This only could 1--2 things, a bad circuit board fan relay or bad thermostat. To check for bad thermostat, take off the front cover to reveal the 4-wire terminial and jump the red-wire (power)-cool,(yellow -y or blue)--- green--fan white-(heat)..........red to yellow-or y=cool. Thank-you-very-much!
