Bests & Worsts Reviews from Amazon

My husband installed the 18000 downstairs in our 1,700' log cabin, to test. He wishes he ordered the 24000 it works so well, instant heat or air. We are putting a 13000 upstairs. These are excellent, we are putting them in our rentals and Hunting Lodge on the East Coast. The only issue is these are not pre charged. Amazon is so great, they paid for a plumber to charge the lines, who cost $100 and it worked immediately.
