Koontz Heating & Air

Koontz Heating & Air has been a Daytona Beach fixture since 1967, when a Navy veteran founded the company that still carriesCAC1822599, CFC1433230, and EC13015132 licenses. Today the team operates from a single truck yard serving 18 towns across Volusia and Flagler counties, from Palm Coast to Titusville. The company holds a 4.9-star average across nearly 1,500 reviews, a rare concentration of homeowner feedback that reflects consistent performance over decades in Florida's punishing summer climate.

What separates Koontz from regional competitors is their breadth: one company handles HVAC, plumbing, and electrical work with the same crew, same trucks, same standard. They are an authorized dealer for major brands with factory-trained technicians, and they offer twice-yearly maintenance plans designed to catch problems before August heat pushes systems over the edge. The website advertises a $99 tune-up special for new customers, and free estimates on new system installations come with a unique guarantee: a free second opinion on any competitor quote.

Customer reviews tell specific stories. A reviewer in the heat wave of spring called at 9am with a dead AC and Marcus arrived by 1pm, fixing a bad capacitor in 40 minutes at the quoted price. Another reviewer with a 26-year-old gas system found every other contractor inflated prices for an electric replacement; Matt and his crew handled it as a routine job. A third reviewer described a flickering electrical panel that two other companies said would need $4,000 in panel replacement, only to have Koontz's technician diagnose and swap a single bad breaker for $180.
