well! there several factor to be consider in
insufficient cooling effect,
1. under charge, low charge of freon
how to detect: Check oprerating current
using clamp ammeter ,
clamp on one line and
take reading compare
this to rated current on
manuals if below
your system is under
freon 22 ,if same is good
check also on sight
glass located on hi side
if bubbles appear your
system is under charge
irecharge if clear still
Freon 22 and others are refrigerant gas and easily evaporate when they escape on athmospheric pressure.they are dagerous to our athmosphere if they expose,they destroy our stratosphere that filter sunlight coming to earth the radio active of sun cannot enter or block by stratosphere if this destroy radio active affect our mother earth.
so in charging freon,they should not escape or leak in our athmosphere take all necessary precaution,there is international law about freon leaking on air,try to update on this issue.
2. evaporator coil and blower should always maintain in obstruction and paricles blocking the fin.if the ice is developed on eveporator this mean evaporator is dirty need to be clean also with fan and blower.they cannot blow air sufficiently due to ice solidified on fin to block air passage.also, on condenser tube fin don let to distored rejection of heat sufficienly help good evaporation of freon .
if fan and blower has insufficient in blowing of air, change bearing, perfomance
will improve in full effeciency.
so cheers and have a nice day to london

SOURCE: split ac not cooling
I would check the drain to see if it is stop up.Next check to see if the unit inside is freezing up.If it is check to see if fan is running and if fan is running the you proable have a freon leak. Low charge on freon will make it freeze up and the fan not running also.

Gas has leaked from inner or outer unit kindly get it checked by service men they will find the leak and charge the gas again normally after some time it gets rusty inside as water is involved and got leak
no problem get it repaired not expensive
