4.9 stars across 1454+ Volusia County reviews.
Called at 9am with a dead AC during the first hot week of spring. Marcus was at my door by 1pm, fixed a bad capacitor, charged me what he quoted, and was out in 40 minutes. Real Daytona service.
Replaced a 22-year-old system. They were the only company that didn't try to sell me a bigger unit than I needed. Quote was fair, install was clean, and the new system is dead silent.
Had a flickering panel issue that two other companies told me would need a full panel replacement ($4k+). Koontz's guy diagnosed a single bad breaker, swapped it, charged me $180 total. Honesty is rare.
