OK, we don't have gas where we live but we already have ducted evaporative cooling installed in our new house. We don't have any heating at all so we are looking at our options for the winter.
Would you just go and put in ducted reverse cycle in all the rooms?
Which companies have you used for your reverse cycle systems?
How big is your house? How much did it cost?
We used Climat to put in a Daikin system in our previous house and that was good.
