Let me tell you something so far this is my top rated go to company. They are courteous and friendly and so willing to help and dig and really find out what the problem is and when its time to do anything with my A/C unit they are the only company I will be reaching out to. I mean Juan really took his time and I really appreciate his efforts and communication to me. Thank you to Samantha for making me feel like I mattered and to the boss that authorized extended work that they really didn't have to do. So coming from a disabled Army Veteran, I salute this company.

I’m so grateful for this company and their service. We had an issue with our AC unit that got installed just over a year ago by another big company, and we have a “premium” service with them, so a technician came from that company here before Juan to tell us that the main board was ruined and we were quoted 700 dollars at least. Thankfully we thought of getting another opinion. Juan showed up, looked at every possible situation that could be happening, found that the main board was fine, and kept looking until he found that the issue was just a wire that was not communicating with the unit in our attic. Thank you, Juan!

Recognized by Synchrony and Guide to Florida

We did not buy this credibility. It came from a national finance partner and from Florida customers who voted.

2021 Synchrony Pillars Project Winner. Synchrony named Synergy a winner of The Synchrony Pillars Project Grant, which recognizes small business owners who have risen above in times of change. Synergy came up through the pandemic years, worked through staffing shortages and early losses, and used the grant to expand what it could offer customers. Synchrony told the story on its own channel (watch the video).

2024 Best of Florida Regional Award. Awarded by customer votes and featured by Guide to Florida — recognition that came from the people we actually served.

2025 Best of Florida Honorable Mention. Named again the following year in the HVAC Sales & Service Companies category.

Behind all three is the same thing: Roy and Samantha Durkee built this company by treating neighbors like neighbors — including a community fundraiser that put a new three-ton system in the home of a recently widowed customer.
