# Florida HVAC Replacement Cost

> What sets HVAC replacement cost in Florida in 2026: sizing and humidity, the 14.3 SEER2 Southeast rule, the R-454B change and hurricane anchoring. Free quotes.

## Key facts

- Florida sits in the Department of Energy's Southeast region, so a split-system air conditioner installed in Florida must meet 14.3 SEER2 under 45,000 Btu/h, or 13.8 SEER2 at 45,000 Btu/h and above, against a national manufacturing minimum of 13.4 SEER2 (10 CFR 430.32(c)(5) and (c)(6)).
- New residential and light commercial air conditioning and heat pump systems must use refrigerant with a global warming potential under 700, with an EPA compliance date of January 1, 2025 for manufacture and import (EPA, Technology Transitions HFC restrictions by sector).
- Florida air conditioning contractors are licensed through the Construction Industry Licensing Board as certified contractors, who may contract anywhere in the state, or registered contractors, who may contract only in the jurisdictions where the registration was issued (Florida DBPR).

## Data

- What moves a Florida HVAC replacement quote, 2026. Methodology: Cost-driver table, not a price table. We publish no dollar range for Florida because a credible one would have to be invented: quotes here turn on tonnage and equipment type, duct condition, air handler location, coastal exposure, wind anchoring, flood elevation, permit requirements and access. National averages capture none of that. The regulatory drivers below are sourced to the EPA, 10 CFR 430.32 and Florida DBPR and were checked on 2026-08-14. Use the last column as your quote checklist.

## About

- Florida HVAC Replacement Cost is a free introduction service; we pass your details to HVAC contractors covering your ZIP code, who quote you directly. We may receive a fee from providers; you pay nothing and are under no obligation. We are not contractors and we are not affiliated with the EPA, the US Department of Energy, Florida DBPR or the Construction Industry Licensing Board. Nothing here is engineering, legal or code-compliance advice: confirm permit, anchoring and inspection requirements with your local building department, and confirm refrigerant dates against epa.gov, because those rules have changed repeatedly.
