HVAC Service & Maintenance in St. Johns, FL
HVAC repair, maintenance plans, duct services and new construction HVAC in St. Johns, FL, from a family-owned Northeast Florida company.
Homeowners in St. Johns can call Cool Cats for the everyday side of HVAC: tune-ups, repairs, duct work and indoor air quality, along with HVAC for new homes being built in St. Johns County. We serve St. Johns from our Jacksonville office.
Picking a maintenance plan that fits
We offer three plans. The Cool Cats Tune-Up Club ($149 a year) covers one Precision Tune-Up with standard scheduling. The PAW Club ($219 a year) adds a second tune-up, priority scheduling and 10% off qualifying repairs. The VIP Club ($24.99 a month, 12-month commitment) includes two tune-ups, priority scheduling, 15% off qualifying repairs, waived diagnostic fees and $100 a year toward a new system, up to $500 per enrolled system. All plans renew automatically, and your signed agreement governs the full terms.
Duct cleaning or duct repair?
They solve different problems. Duct cleaning removes buildup inside the ductwork. Duct repair or replacement fixes leaks, damaged runs and disconnected sections that waste cooled air. We also install air purifiers, UV lights and dehumidifiers for homeowners who want to improve their indoor air. We'll inspect first and recommend only what fits your system.
Building a new home in St. Johns County
For custom-home owners, builders and general contractors, we provide new construction HVAC sized with a professional load calculation and matched to Ruud or Bryant equipment options. Bringing us in during planning makes it easier to coordinate equipment and duct layout with the rest of the build.
AC Installation & Replacement in St. Johns
Every replacement starts with a free estimate. A technician will:
- Inspect your existing system
- Measure your home
- Talk through the comfort issues you've noticed
- Perform a professional load calculation
- Present multiple options
We install Ruud and Bryant systems. The right choice depends on your budget, efficiency goals, the application, and equipment availability. Cool Cats pulls the HVAC permit, and the permit cost is included in your quoted installation price. A normal residential change-out takes one full day. After you approve, installation is typically available within two weeks, depending on equipment availability. Every installation carries our two-year labor warranty, and financing is available through Wells Fargo and Synchrony.
