I bought this item to keep my dogs cool in the summer and warm in the winter while I am gone to work. My dogs have a custom build dog house 4x8 feet, insulated with shingled roof. Therm-assure heat/AC unit installs easily and keeps the doghouse cool in the summer and warm in the winter. Now I don't feel guilty putting my dogs outside while I am gone to work during extreme temperatures and I don't have to leave them put up in a crate all day for them to have heat and air conditioning. I know this may sound extreme, but I love my dogs. The cost is around $400 dollars but it is a heating and air unit, easy to install and made especially for dog houses, plus it puts my mind at ease knowing they are comfortable.

Pros: Wonderful Unit, my dogs are happy while I am gone to work now

Cons: Expensive!
