Evan did a complete analysis of the system before he made a decision about the issue. After that he did some reworking and the communications wiring, cleans up some loose tape issues and fixed a loose panel on the inside cooling coils. I was told by a different company that I had to replace the whole system which I didn’t feel comfortable about. Evan corrected and cleaned up the communication wiring and added some Freon. Now the system is working properly and at a reasonable price. I would highly recommend ( A 100% Gaurantee Heating &A/C LLC). Mike D.

I hired A 100% guarantee heating and AC to remove 3 air handling units on my commercial warehouse so that the roof could be repaired and the units be reinstalled. When I first met with Evan, the owner, he seemed knowledgeable, but he created a complete nightmare for a simple task on my property and eventually caused over $20,000 of damage to my building and its contents. I have reached out to him for the last month and he will not even bother to talk to me. The first cause of major damage occurred when he ordered and improperly installed the wrong curbs for the units creating a 6 week period where I had 3 large holes in my roof where the air handlers were removed from. He removed his original improperly installed curbs (see photos) and during that time period he assured me if it rained that he had covered the openings and no water could get in. When it did rain his covering failed and ruined an $11,000 printer in the office space down below along with damaging the building. Finally when the new curbs came in and everything was installed he had done so much damage (punctures/tears see photos) to the brand new roof surrounding the areas that he was working that I had to spend $9,000 replacing the brand new section of roof. I also had to hire another company to properly install the duct work because there were large holes left for the air to escape into the non conditioned space. It’s clear Evan does not care about the destruction he left behind.

These people are absolutely amazing. I spoke to Katrina and Ryan was the one that actually did the work. Both super friendly and very professional. Ryan arrived on time and completed the work in a timely manner... I am very pleased with my thermostat install. I definitely recommend this company.

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!
