“Working with Service First HVAC for my Mitsubishi mini-split purchase and installation was an absolute breeze from start to finish!
From the initial consultation with J, it was clear they really knew their stuff. Danielle provided an estimate and install promptly. They helped me pick the perfect Mitsubishi system for my space without any high-pressure sales tactics. On installation day, the crew arrived right on time, were incredibly professional, and kept the workspace spotless.
The unit itself is whisper-quiet and works like a charm. It’s rare to find a company that combines technical expertise with such genuine, friendly customer service. If you’re looking to upgrade your home comfort, I can’t recommend Service First HVAC enough—they truly live up to their name!“

“We got referred to GMI by a friend to help us install the HVAC system in our unfinished basement. Spencer was our initial contact who was incredible at brainstorming the project with me and going over a gameplan of how to be meet our needs. He was very honest about what would and wouldn't work and how we could do things to best fit our budget. We decided to move forward with them and they had a team out to install our system the following week.Ramone, José, and Mario did all our wire pulling and ductwork and I have to say they were a joy to work with. They went above and beyond to help me maximize my ceiling space and were very punctual and respectful. They took the time to walk through what they were going to do and ask questions to make sure it was exactly what I wanted instead of just assuming and throwing stuff up wherever. They even tidied up every night before leaving instead of leaving a mess everywhere.Spencer then came and did a final walkthrough with us and made sure everything was to our liking. All in all we had a great experience and I would highly recommend them!“
