AC installation cost by system.
Installed pricing for Longwood, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Longwood, Florida, AC installation costs typically range from $3,500 to $7,000 for a like-for-like central AC replacement, while a new system with ductwork runs $5,200 to $11,300+. Ductless mini-splits cost $2,600 to $7,000, and heat pumps—recommended for Longwood's hot-humid climate—range from $4,300 to $10,400+. The median home age of 47 years often means older ductwork or undersized systems, which can increase labor and material costs. Florida law requires a mechanical permit and a Manual J load calculation for any new installation, and outdoor units must be hurricane-tied down per the Florida Building Code. Federal tax credits (up to $2,000 for heat pumps, $600 for high-efficiency AC) can offset some costs.

Recommended unit for Longwood
Given Florida’s hot-humid climate and heat-pump heating, high-seer2 heat pump is the sensible default for most Longwood homes. With a long, hard cooling season here, stepping up the SEER2 tier pays back through lower summer bills. A pro can confirm the right size and system for your home with a load calculation.

- Good to know—
Florida Building Code requires hurricane/high-wind tie-downs and anchoring for outdoor condenser/heat-pump units.

AC Installation in Longwood, explained.
What Drives AC Installation Costs in Longwood
In Longwood, the age of your home (median built 1979) often means ductwork modifications or replacements are needed, adding $1,500–$3,000. System choice matters: heat pumps are more efficient for year-round use but cost more upfront than standard AC. Permit fees, load calculations, and hurricane tie-downs add $300–$600. Higher-efficiency units (SEER2 ≥ 14.3) qualify for federal tax credits but have higher purchase prices. Labor rates reflect local demand and the complexity of working in existing homes.
Common AC Installation Issues in Longwood
Undersized Ductwork
Older homes often have undersized or leaky ducts that can't handle modern high-efficiency systems, requiring duct replacement or sealing.
Hurricane Tie-Down Requirements
Outdoor units must be anchored to meet Florida Building Code wind-load standards, adding cost and complexity.
Refrigerant Transition
R-410A is being phased out; new systems use R-454B or R-32, which may require different handling and affect pricing.
