All the locals say heat pumps do not work well at this elevation, and most HVAC locals have NOT installed HP's--sometimes maybe only (1)--most are not up on the latest technology!

I really want to install top of line air to air HP--ground source is not a option as it is way to rocky, and of the expense.

I would really like to hear from the pro's--and any homeowners, that live at higher elevations, with HP, and there performance--thanks
