Hey bros..
Had my first air con serviced for my LG aircon. Can't remember which model but it's made in Korea and bought from Courts last year (System 3).
Anyway, when the service guys came over, they only brushed, vacuumed and washed the filters/ internals. No oiling or gas top up like I saw when I was a kid more than a decade back..
Aircon feels cleaner and stronger but not cooler. There is also weird rusty sound on the flaps coz I know they didn't oil it?
Questions:
- usually what to expect for air con service ah? The receipt says 'maintenance' but it is just cleaning, and it costs $105. They didn't even touched the compressor..
- what sort of maintenance must be done periodically or ask from the service company? If air con 'service' is only cleaning, not worth the price leh.. I also know how to wash the filter. And after closely observing at them dismantling the casing, I now also know where to clean deeper.
Anyone can share their advice and experience? Really noob at this... Coz the aircon fellas who cleaned my aircon say need minimum 2x servicing a year, ideally 4x a year. I not sure what sort of services really required... Needa consult with you all before I tio chop lol..
Many many thanks in advance!!
Hi Segafan,
Hope this can help and solve your queries;
WHY SHOULD OUR AIRCON BE SERVICE ON A REGULAR BASIS?
1. SAVE ON YOUR POWER BILL
Servicing a dirty aircon can save you up to 30% power usage for that unit. A dirty coil means the unit has to work harder to cool the air because there is much “less clean” surface area for the hot air to pass over. If the blower fan (drum) is covered in dirt and grime – air velocity decreases dramatically and so you are tempted to turn up the fan speed and turn down the temperature in order to cool the room down. This of course is going to use more power! CLEAN AIRCONS MEANS LESSER POWER USAGE AND COOLER AIR!
2. MICROBIAL CONTAMINATION
The second reason is especially significant to allergy suffers, children and the sicks. All aircons, after regular usage, become infected with “microbial contamination” – This contamination includes fungi, mold and bacteria. Aircons are the perfect environment for such contaminants and of course, become constantly airborne every time you switch your air conditioner on. Mold combined with humidity can be a potent mix!!! CLEAN AIRCONS MEANS VIRTUAL ERADICATION OF MICROBIAL CONTAMINATION AND CLEANER AIR!
3. YOUR AIR CONDITIONER WILL LAST LONGER
This is your contribution to the environment. It’s called SUSTAINABILITY! A regularly serviced air conditioner will last a lot longer than one that never gets serviced. The only reason you wouldn't service it, is if you never used it!! In summary –consumers are generally not made aware of the above and so are under the belief that cleaning you filters is enough. Cleaning your filters is “simple maintenance”. After regular usage the whole head unit also needs to be “correctly" serviced.
OUR NORMAL SERVICE INCLUDES;
- System examination and cleaning of fancoils
- Check, clean and wash fancoil’s air filter
- Check and clean cooling coil, water tray and blower
- Check suction/discharge pressure of the compressor(s)
- Check on seals and joints of pipe for leakage, repair if necessary (chargeable)
- Check on bolts and nuts for tightness and corrosion
- Check all safety circuits and test run aircon units after each servicing and repair work
- Inspect equipment for refrigerant gas leak
There is standard procedures and steps to follow for aircon servicing. Eg, how to remove and re-install aircon cover and parts (if necessary), how to prevent electricity and refrigerant gas leak during servicing. If it's done wrongly, it may spoil the aircon or aircon parts which will cost more for repair eventually. And also, stronger wet and dry industrial vacuum cleaners are needed to vacuum deeper into the aircon fins and parts for a thorough service. Normal household vacuum cleaners are not strong enough to vacuum out the dirts that deep within. With the stronger wet and dry industrial vacuum cleaner, it can also vacuum the water pipes to prevent cloggage.
Your relatively new aircon system that was just installed last year should not require any oiling or refrigerant gas top-up. Aircon servicing frequency depends on your usage and age of aircon. Normal service twice a year should be good enough for now, increasing the frequency gradually as the years goes by. Normal service x 3-4 times yearly or chemical overhaul x 1 time + normal service 2-3 times yearly will be recommended in future.
