Dry bulb. Wet bulb. Constant zone. Kilowatts. Registers. One phase. Three phase. Unfazed.
Apologies to the poor heating/cooling specialist who tried to explain to me on the phone how the innards of our future air conditioning system could be concealed in our house. “Do you mind putting something on email so I can think about this later?” I said.
The air conditioning needs to be considered now, so that the builders can plan for the slab penetrations. I have two quotes so far and another on the way. So far I have one quote for apples and one quote for oranges. The first quote, lets call that the apples, warned me against quotes for oranges, but quite frankly, I’m leaning towards the oranges. The “apples quote” is a two-unit system. Mitsubishi. Probably it could keep our large house with it’s big open spaces at a constant temperature year round. This quote is $60 000. Startling, even before you consider running costs, which I am told could be up to $6 per hour.
The supplier of the “oranges” came recommended to us by fellow canal dwellers, already an advantage. The “oranges quote” is for just a single unit system, with brand options including LG, Mitsubishi and Fujitsu. This quote is about $15 000, depending on the brand.
Perhaps a single unit system will struggle to cool our large house on some of Mandurah’s hottest days. Mandurah has a subtropical climate with an average of 9.5 days per year at 35 degrees celsius or hotter and 46 days at 30 degrees celsius or above. But we are not wilt-in-the-heat kind of people, and we are going to have a swimming pool. In Winter, it never gets below zero and we do own jumpers.
Calling all Mandurah double story house dwellers, please tell me if your A/Cs are apples or oranges.
Edit. The 3rd quote has just arrived. 2 unit system – Daikin. $27 000. Could it be a lemon?
