Was that $3,000 in addition to the unit cost? Your total cost?
Please break it down for us.
Remember, with inverter technology, it's a variable speed system, so if you buy
too many BTUs, it's not a problem, the unit will just run less power on mild days.
And be able to easily cool or heat the same areas on those extreme days.
My Sanyo uses about the same power as a small window AC, when it's just
maintaining the setpoint on mild days like this one..
It draws more power when we open up cold rooms to the rest of the house, or turn up the heat a bit.
If you can afford it, get all the BTUs you think you will ever need..
If the step up from 24,000 ($2211.00) to 36,000 ($3270.00) wasn't such a jump in price,
I would have gone for the 36k..
(Those are today's prices).
