Frugal and Energy Efficient Living

My grandson is an hvac genius!

Perhaps only good for warmer days in severe climates.

And you need to choose to optimize for heating or cooling. I chose cooling because this place is a hot, muggy hellhole most of the year, yet gets down below zero sometimes in winter.

Depends, too on layout of house & how it is placed. I have an outdoor unit & an indoor unit paced facing the hallway to the bedrooms, a bit off-center to hallway. (1250 sq ft ranch)


I keep it about 65 in summer & 75-80 in winter in my home. Very few days here heating or cooling are not needed, but on those daysl, I usually run the dehumidify function. So mine is rummimg 24)/7, 365 just about. It is an inveryer unit, so it literally runs constantly. Amazing really that it is so much cheaper to run than a ducted unit. So muxch energy loss thru ducts!
