This was my second time using their service. The owner, Jerry, responded to my inquiry very promptly and was able to accommodate my schedule with no hassle. Communication was clear and consistent from start to finish, which I really appreciate. AJ, who came out to work on my A/C, was professional, friendly, and did a thorough job. He took the time to answer all my questions in detail. I think he spent more time making sure I understood everything than working on the unit, which speaks volumes about their dedication to customer satisfaction. Highly recommended! I will be using their services again in the future.

Thank you Evan for all your hard work and dedication to completing this project. I'm very happy with my new HVAC, the heater works great. When I was shopping around for contractors to help me with a new HVAC, Evan with A100% was the only one that would replace the recommended copper pipping that connects to the furnace/condenser. The other contractors are just going to flush the pipes and use the old smaller existing pipes that might not be suitable for the new HVAC system. They also did a great job in updating my old ducts, I have very little air loss. And many thanks to Catriena for helping me with the financing and the application for the inflation reduction act rebates. I would not have been able to do this without that. I completely recommend A100%, they don't just do the job, they do it right!
