I decided to install a Mitsubishi Dual Mini Split Air Conditioner in my basement, but lacked the wiring and expertise. Zach took the time to explain all of the options available to me, submitted the best proposal, and guided the entire process. Everything was done on time and on budget. Quality work. I’m definitely going to stick with them for all of my HVAC needs…and I’m super picky.
