Hello all sifu... Do you all have any contractor for air con installing at Damansara?

Job I need to do:

1) Remove my room air con and install in another room where another room already has a unit of defect air-con.

2) Install a new air con in my room.

What is the normal labour price for dismantle, installation only?

If I get the new air con from the contractor do I have free labour charges?

Thanks
