Once the air-conditioning system is installed and operational, it is also important to have the system regularly serviced to avoid issues with the system.
Proper Servicing of the air-conditioning system includes these 4 steps:
1. The air filters need to be cleaned to keep the air inside the house cleaned and prevent dust to accumulate and clogging the air filters. Some air filters can get clogged so badly that air can barely pass through.
2. The evaporator coil is cleaned to ensure effective cooling. Lack of servicing will cause the evaporator coil to clog fast and additional cost to clean the clog on the coil will be incurred to restore back the cooling (eg through chemical wash, steam cleaning).
4. The condensate drain pipe need to be cleaned to prevent water accumulation inside the pipe. If there is a lack of servicing on the drain pipe, the inside of the pipe will get clogged and this can cause water leaking at the condensate pipe end. One possible reason for the clogging can be due to jelly formation because of water accumulation and stagnation inside the pipe.
It should be noted that while the above cleaning operations (eg cleaning air filters, cleaning evaporator coils, cleaning fan rotors and cleaning condensate drain pipe) look simple, it is highly advisable that regular air con servicing is carried out by a competent and trained technician as some air-conditioning repair works require complete dismantling & disassembling of the indoor Fan Coil unit parts that only trained & competent air con technician can carry out.
Besides the above, the trained technician will also be able to advise on the system operating conditions with records on the operating pressure, running current and voltage, off coil and on coil air temperatures and air velocity from the Fan Coil unit. The trained technician is also competent to recommend preventive repair works and rectify on the issues before breakdown of the air con system.
