MAKE SURE YOUR INSTALLER IS LICENCED
A refrigeration mechanic installs it and an electrician is required to wire it. You must receive a certificate for both parts of the installation.Some highly skilled electricians also carry a licence to install the air conditioner and wire it. It is important to make sure you do not opt for cheap installations, as air conditioners have ozone depleting gases inside them.
Not only can these gases hurt the environment but the lose of gas when being installed will also affect the proper running and efficiency of your unit.
PRICING OF EXTRAS (MATERIALS)
Getting a licenced air conditioner installer also gives you great peace of mind knowing that if any problems occur down the track, it was installed in accordance with the required regulations and you have the compliance certificates.
