We want to get a second heatpump installed. The first one came with the house but the installer is a one man band & we want to get it done quickly.

It seems that CozyCool are the big name for heatpump installation in Wgtn.

Has anyone had experience with them - are they good?

Also are there generally any issues with having two heatpumps? Is it better to just replace the first one with one that has two outlets or just have a second external unit placed next to the first one?
