Arrived on site for no Cooling. Customer led me to air handler condenser and thermostat. Set thermostat to cooling. Saw the air handler and condenser power on normally. The temperature difference inside the house was 10° different. Went outside to the condenser and check pressures and pressures were a off, with high pressure getting to 300. The unit has a closed coil so can't check for piston or TXV. Can't check the evaporator coil since there is no access. Filter has not been changed and or washed for over 2 years. Washed out the filter outside with the customer's hose. Washed out condenser with chemical and water. The pressures of unit got significantly better after washing down the unit. The cooling inside the house went up to 17° difference. Customer stated they feel the cooling more efficiently now and acknowledge the updated information of the unit, signed off.
