Michael and his team did a fantastic job at my property. They were tasked with adding AC to an existing central heat system in my home. They were professional, courteous, knowledgeable and fast. The job took them a total of 2.5 days! I was thoroughly impressed, and their pricing just couldn't be beat. Not only did I feel that I got what I paid for, I feel that I got more! We had some questions about our system after it was installed, and Michael made it a point to come personally and elaborate *on a holiday*! Seriously blown away at how awesome the service was. Our home feels like a new home now with a stellar performing AC system. Thanks guys!

I have one issue with Mike: he can't clone himself. There aren't enough good people like him nor enough good techs and business owners. I bought my first home, a multi-unit property in June 2023. I was told the first year is always the most difficult and my house made sure to prove that point 100% correct. My first month in the house, we had a significant heat wave which led me to seek cooling for the units. I had two HVAC installers come by to look at the job. One guy couldn't come up with many good ideas and was hesitant on how to accomplish routing for my 4-unit property--granted, it's a 1921 home that was subdivided, so it's not as clean-cut as you would think. However, when Mike came by, he took a look around and could immediately envision what would be the most space and cost efficient. He quoted me at nearly half what the other company did and came up with solutions to save money. He got to work and faced numerous obstacles due to the fact that some of the remodeling done to the home was sloppy, yet he ensured the installation was solid and up to code. He's a man of his word--never once entertained raising the price even with the many headaches and frustrations my house caused him. He got everything installed in October and all was great until the January flood, which washed out a good bit of my landscaping and almost took out my HVAC units. Just a month later, my main sewer line backed up into my house, so Mike had to disconnect the units for the plumber to get to the main. Seeing the many issues I was having, he disconnected and reconnected the units for me at the best price you can get. All this to say, Mike is more than just the expert HVAC guy, he's a good friend that would give the shirt off his back. If you hire anyone else, you're doing yourself a disservice.

Mike is AMAZING!!!! Super nice guy who came out to our house very quickly and got us enjoying cool air again. He was by far the most responsive, personable and best pricing. I would absolutely recommend and will use in the future.
