Gus repaired my old outside AC unit. He was polite, knowledgeable and most importantly he fixed the issue. It's rare to find someone like Gus who can troubleshoot and fix HVAC issues without the first solution being a full system replacement.
Outstanding service ! Within an hour Gus came to fix the problem I was having with my heating system. He also fixed my central air conditioning unit a couple of years ago. He’s knowledgeable, honest and reasonably priced. If you have any issues with your heating or air conditioning systems I highly recommend him. ……………. With 90 degree temperatures and a problem with my central air conditioning unit I knew Gus was the right person to call. As in the past he came quickly to resolve the issue. Don’t hesitate to call him for your air conditioning and heating issues. He’s the best !
Gus has been supporting my home's AC needs for the last several years. He has replaced a AC condensor as well as annual maintenance. Gus has always gone the extra mile to ensure he can work me into his busy schedule espcecially during peak times. The last two years he has been a life saver supporting an older condensor and always following up to make sure all things are running smoothely. He has always treated me fairly regarding price and service.
This was the best experience I've ever had with a contractor in my home. Gus and his crew were neat, polite, reasonably priced and just delightful all the way around. His expertise is exceptional and his care and execution of the work was phenomenal. Everything works! I didn't have to worry about a thing; he walked me through each stage and made this an extremely easy experience. If you need work done, save yourself some time and go directly to Adam's Air Conditioning and Heating. Gus is the best!
We recently installed a new furnace and air conditioner from Adam’s Air Conditioning and Heating and are exceptionally pleased with the results. Gus (the owner) came to us highly recommended and we were not disappointed. He is a truly skilled HVAC craftsman as well as trustworthy and meticulous in his work. Our town inspector commented on the quality of the work completed as a “beautiful job”. We are very pleased with the results and will not hesitate to recommend him to others.
I truly can’t say enough about Gus. He was a trusted resource during our time when we need to replace both our heater and AC systems for our old house, and he was extremely meticulous with his work. Other people in the house have commented multiple times on the great work he’s done. I’ve already recommended him to a few people and will continue to do in the future. Glad we have found our go to in the Caldwell area moving forward for all things HVAC.
Gus is great! Friendly, knowledgeable and fair. Quickly showed up, diagnosed and fixed the problem with my boiler.
Our furnace went down on a Sunday morning and Gus was here within a few hours, came up with a fix that got us through the day and came back the next day once he was able to source the parts needed. He is super friendly and respectful and I would recommend him to anyone needed HVAC work done on your home.
I would highly recommend Gus to anyone in need of HVAC help. Our furnace was having issues during a cold snap this winter and he came by same day to diagnose and resolve our issue, quickly, cleanly and professionally. He listened and shared his honest opinion based on deep knowledge and experience. 5 stars and my highest compliments!
