Cost of HVAC Replacement in Orlando, FL (2025)

A 3-ton system (typical for a 1,200–1,500 sq ft Orlando home) costs $4,500–$8,000 installed. A 4-ton system for a 1,500–2,000 sq ft home runs $5,500–$9,500. Larger 5-ton systems for homes over 2,000 sq ft cost $6,500–$12,000.

These prices include the air handler, condenser, refrigerant, labor, and basic electrical work. Ductwork repair or replacement adds $1,500–$5,000 if needed. A smart thermostat upgrade adds $150–$400.

Premium brands (Trane, Carrier, Lennox) cost 15–25% more than value brands (Goodman, Rheem) but often include better warranties — important in Florida's demanding climate.

System sizing is critical. Orlando homes need approximately 1 ton of cooling per 400–500 sq ft, but ceiling height, insulation quality, and window exposure all affect the calculation. A proper Manual J load calculation is required — oversizing causes humidity problems.

Florida requires a minimum 15 SEER2 efficiency rating on new systems. Higher efficiency units (18–21 SEER) cost $1,000–$3,000 more upfront but save $300–$600/year on electricity bills in Orlando's climate.

Heat pumps are the ideal choice for Florida. They provide efficient cooling and heating using the same system. Since Orlando winters are mild, a heat pump handles all heating needs without a gas furnace.

Most HVAC replacements are completed in a single day. Equipment availability can add 1–5 days if specific units need to be ordered. Emergency replacements during summer peak season (May–August) may have 1–3 day lead times.

Demand spikes in May–August when Orlando temperatures regularly exceed 90°F. Book in advance or expect 1–2 week wait times during peak season. Fall and winter installations often come with promotional pricing from contractors.

A mechanical permit is required in Orange County. Your contractor must pull the permit and schedule a city inspection. Permit fees run $75–$200. Never use a contractor who skips the permit — it affects your homeowners insurance coverage.
