in the last week⭐⭐⭐⭐ Outstanding Craftsmanship & Professionalism — Highest Recommendation I recently had Alexander Heating & Cooling install an 18,000 BTU Mitsubishi mini split in my garage gym, and I cannot say enough about the quality of their work and professionalism from start to finish. Chris, the owner, runs a tight ship — and it shows in every detail. Jason, the technician who performed the installation, is simply exceptional at his craft. The job required drilling through filled cinder block walls, which is no small feat, and they handled it with precision and complete confidence. When the work was done, everything looked immaculate — not “good for a garage,” just genuinely, beautifully done. What truly set this experience apart was watching them work. Both the interior and exterior units were installed with meticulous attention to detail, clean lines, and obvious pride in the finished product. They treated my garage workout space with the same care and respect they would give a living room. That kind of craftsmanship is increasingly rare, and it did not go unnoticed. The entire Alexander team clearly takes ownership of their work — not just technically, but aesthetically. They care how it looks when they leave, and that speaks volumes about the character of this company. I was so impressed that I’m now planning to use Alexander Heating & Cooling for service and maintenance on my other two HVAC units. When you find a team you can trust to do exceptional work, you don’t let them go. If you’re looking for an HVAC company that combines real skill, attention to detail, and genuine professionalism, look no further. Alexander Heating & Cooling has earned a customer for life.

in the last weekMy wife and I were looking for a new AC company to do our maintenance and any repairs. We have had agreements in the past with other larger companies and we always felt they were trying to up sell us, even on parts we didn’t need. So obviously we were looking for a smaller, more personalized company. We found it in Alexander Heating and Cooling. When we called, they were quick to help. When it came time for the appointment, Matt was early and very respectful of our system and house. There was no effort to try to sell more than what we asked for or needed. This was a great experience and Alexander Heating and Cooling is our new AC company. Oh and the owner of the company texted a follow up to make sure we were satisfied.
