Call the surrounding vocational schools! We called the local vocational schools where workers are trained to work on air systems. Every instructor said Trane was the best for regular ac/heat. We bought a the Trane system with heat pump. I set the temp to be automatic 72 degress year round and haven't had to reset it since. We have a maint. check up in the spring and fall.

In my previous post, I told about geothermal heat ($50.00 a month this winter in Wisconsin), but with geothermal, you also get air conditioning and hot water. The water is heated only when the unit is heating or cooling, so sometimes in the spring and fall (and actually most of the summer here under the trees), the water is heated with electricity.

My dh recommends the mini split system for your situation and feels it's the most efficient. Good luck with whatever you go with.

Did you find the system right for you and what did you go with?

We installed a new system last month: a Geo Thermal cooling and heating and love how it works for us...cut the electric bill by fifty per cent! Uniform cooling in all rooms, never hear it running, and so clean in North Central Missouri in Gardening zone five.

Have no advice on any new systems. We purchased a Carrier at a yard sale and have had it for years. It really runs well.
