GENERAL
SERVICING
-
Pump down the system and dismantle the fan coil unit alone (FCU/indoor unit)
-
Clean the FCU using a pressure washer (using of coil cleaner chemical if necessary only)
-
Vacuum/blow the condensate drain pipe.
-
Remove cover and clean the condensing coil fins using pressurize water (dismantle excluded)
-
Re-install the FCU, vacuum the refrigerant system, leak test and refill the refrigerant if necessary
-
Check the operating pressure and current
-
Observe for normal working operation
-
Additional charge for CU will impose:
MAINTENANCE
CONTRACT
-
Combine both Routine Servicing and General Servicing.
-
In a one year period, we will arrange for 3 routine servicing and 1 general servicing.
-
Much cheaper than buying one off.
-
Allows you to maintain your Air-Con for longer.
REPAIR
REFRIGERANT LEAK (COMMON)
-
Minor issues which can be repaired on site
-
Pressure leak test the unit/existing tubing using dry nitrogen gas to verify the leak.
-
Repair the leak without transporting to AEC workshop (refrigerant leaks that identified and can repair on site).
-
Flushing and vacuum the refrigerant system to remove dirt, moisture and leak test.
-
Refill the refrigerant based on the capacity/system required.
-
Check the operating pressure and current.
-
Observed for normal working operation.
REPAIR
REFRIGERANT LEAK ( GENERAL )
-
