I've been wanting to install an air conditioner. The price of the unit doesnt bother me that much.

What bothers me is the installation fee as i'm unfamiliar. Most of the seller says that it comes with installation fee included which is a standard RM250 for 10ft copper and pipe.

But how does the installers know that its within the 250 and they don't have to charge extra?

Has anyone encounter anything like the installer suddenly says they need to charge extra on the day of installation?

And it would also be nice to know how much have you guys paid for installation for those that have installed aircond before D
Your info is much appreciated!!

I am thinking of getting Mitsubishi MSY-jp13vf 1.5hp invertor from Home pro with RM99 installation. How is their customer service? They engage 3rd party installer not their own.
