"Great install team! A bit of a hiccup when they arrived which they quickly resolved. Pre-install responses could have been better at times. Ductless mini-splits are costly but it's delivering! Hopefully, long term I'll be glad I did it."

"We were very happy with them. I think, they were very punctual, I would probably remember if they weren’t. I think, it took one day to install the system. They left the area cleaned and took away the other unit."
