What Affects Your Price?

System size (tons). Larger homes need higher-capacity systems. A typical South Florida home uses a 3–4 ton system, sized based on square footage and heat load.

SEER efficiency rating. Higher SEER ratings mean better efficiency and lower monthly bills but higher upfront cost. We recommend minimum 15 SEER for Florida homes.

Ductwork condition. If your ductwork needs repair or replacement, this adds to the total project cost. We inspect ductwork during your free estimate.

Brand. We install Rheem systems, known for reliability and warranty coverage. Many include 10-year parts warranties.

Permits and electrical. HVAC replacements require permits and may need electrical upgrades. We handle all permitting.
