Alert: consumer beware some of the services provided in the market self-claim chemical wash as chemical overhaul. You can tell there is something very different with the services provided at the price different. So let us share what is the 100% Genuine Chemical Overhaul process scope of work should look like: ✔️Pump down refrigerant gas into condensing unit and lock service valve. ✔️Unsecure flare jointing and disconnect electrical wiring and drain pipe at the fancoil unit. ✔️Dismantle the fancoil unit down from the wall. ✔️Once the fancoil unit is on the ground, proceed to dismantle the electrical circuit board, evaporator coil, drain pan, fan motor and fan blower. Tape up flare opening of evaporator coil. ✔️Brush the electrical circuit board and fan motor surface off dust. Check for any abnormal burnt mark. ✔️The evaporator coil, drain pan, fancoil front cover, fancoil body, fan blower will be chemically washed in the washing area. ✔️Use alkaline chemical instead of acidic chemical which may be more corrosive. ✔️Flush the above parts with water and inject chemical solution. The chemical solution will react with the water and the dirt to cause a forming process. ✔ The forming process should take at least 1 HOUR for 1 unit and 3 HOUR for 3 Unit. It will extract dirt trapped deep inside the parts. ✔️After forming process completed, the parts must be thoroughly flushed with water to remove all residual chemical solution. ✔️Wipe dry all parts and reassemble the fancoil unit back. ✔️Clear the drain piping via vacuuming or flushing. ✔️Install the fancoil back at the wall. Secure the flare joint and connect the electrical wiring and drain pipe at fancoil. ✔️Use a vacuum pump to extract out air and foreign material in the refrigerant piping system. ✔️Unsecure the service valve and test for leakage at fancoil flare jointing. ✔️Test run the air conditioner and checks for correct operating pressure. We know that is lengthy but we just want to let you know are you paying for the right service? Smart people making the smart.
