Great system. Great customer service.

Great system. Cools the whole house. Great customer service. I hired a professional for install but he was done in 4 hours. 2 air handlers and the compressor. Haven't tried to the wifi yet.

Quick and easy replacement

This line set makes it quiick and easy to replace the old one with a more appropriate length. It would get 5 stars if you could order a custom length to be able to avoid managing the coils of extra length that aren’t needed.
