To all the fan proponents, it’s a no go. AZ summers peak at up to 120 day time and stay 95 overnight. A/C systems run almost continuously. If one room generates much more heat than others which requires the thermostat to be turned down, then you run the additional expense of cooling the remainder of the house which doesn’t require additional cooling.@onehole149 One of our customers lives in Guatemala City, and if you think it gets uncomfortable in Arizona, try adding some humidity to that.
He does not like air conditioning (he could have it if he wanted, he's a millionaire and just the art alone in his house is worth more than everything I own), and has our largest amp which has 42 power tubes **per channel**. In his listening room, the amps can be on all day and night (I know because I've been there) and yet the room stays comfortable. This is because he installed vents in the ceiling above the amps. The heat rises, and a low power fan at the other end of the ductwork in the ceiling moves the heat out of the house. He has a light switch on the wall to run the fan. Its silent, inexpensive, draws very little energy and the amps don't contribute heat to the room.
