"Zach was wonderful to work with. He responds promptly, did not try to oversell me an expensive air condition and went above and beyond to address the necessary and urgent services in timely manner. It is refreshing to work with honest people these days and Zach is one of them."

"Had him replace a furnace and water heater (closet install) October’22. The water heater high pressure valve was jammed against the closet wall and leaking after installation. No drain tube was attached to the valve. I sent him a text about the situation and no attempt was made to correct the problem. I had to cut a hole in the closet wall to free up the valve and also had to install a proper drain tube myself. He also left my wood flooring dirty and scratched after dragging the old unit out. As for the furnace, upon opening the filter cover to change the filter, I discovered the furnace/ AC had been running for months with NO FILTER. also he used the old condensation drain instead of replacing. Somehow it became blocked with debris so now water is leaking from the unit. I’m replacing that myself today."

"As a Mechanical Engineer for a large international facilities management company, we source out a significant amount of work. It’s becoming rare to find Contractor’s anymore who deliver knowledge, consistency, and work ethic all in one package, but, that’s exactly what we experienced here with Zack, Skyler, & Cody. Hardworking, dependable, and reliable from start to finish. In today’s industry, that level of commitment is very hard to come by. If you’re looking for a partner you can trust to get the job done right the first time, you’ll find it here. Reliability at its best! Keller Heating & Cooling 👍💪"
