The main difference between these two aircon types is the energy consumption. Since inverter aircons have more adapting compressor motor, you will be able to save more on energy by having an aircon that is not constantly at work, as its speed will depend on the temperature of the room. However, the space and regulations of the building or property still need to be considered, if it permits installation of inverter aircon.

This is necessary to ensure that we can install the accurate system for your property. Assessment fees shall be waived upon commencement of service.

A leak can be caused by something as simple as a dislodged drainage pipe, making the water drain upwards, which, of course, eventually flows back into the unit and down your wall. In this case, it’s a simple matter of correcting the angle of the drainage pipe. However, there are still many reasons to cause this issue, contact our professional team for further information.

No this is not normal and should be looked into by an aircon specialist ASAP, as this could lead to further damages in your air cond.



What’s the best option for the defective air conditioner? Should I repair or replace?

Repairs are always the more affordable options, but the more accurate decision will come from a professional aircon technician who can assess the actual state of the aircond.



I can’t turn on my aircon without the remote control, is there anything I can do about it?

If you encounter unresponsive or defective remote control, you can always use the power and control buttons installed in the aircon and have it manually controlled until you get the remote control fixed.



My aircond suddenly turns off, but I still see the status light blinking. What could be wrong?

This is often a problem with frosted evaporator coil. If left unaddressed, this can permanently damage your aircond.



My aircond is emitting a bad, burning smell, what could be wrong?

This can be caused by faulty wiring, moldy interiors, and even insects and other particles stuck inside your aircon.

This could be an issue in your thermostat that may need recalibrating, or some particle that is blocking your condenser causing difficulty of cooling down the room.

It depends on your settings, but it’s advisable not to set it too low to avoid having an overworked air cond. The ideal temperature is between 23-25 Celsius.



Why is my aircon not cooling the room anymore?

This could signal a problem in your compressor, the part of aircond that is responsible for creating the cold air. Dirty aircond may also cause your aircon to take a lot of time to achieve the desired temperature.
