What moves the price.
System size (tonnage)
A correctly sized system comes from a load calculation, not square footage alone — oversizing causes humidity problems and shortens equipment life.
Efficiency (SEER2)
The jump from builder-grade to high-efficiency SEER2 equipment adds up front but pays back in monthly bills, especially where AC runs most of the year.
Ductwork & extras
Duct repairs or replacement, new lines, thermostat upgrades, and surge protection are the add-ons that separate a low quote from a complete one.
The Islamorada factor.
Permits & code
Monroe County enforces the highest wind-design standard in Florida — 180 mph — plus a Rate of Growth Ordinance (ROGO) that meters building permits across the Keys.
