The South Florida AC Buyer's Guide
A complete, no-nonsense guide to buying a new air conditioner in South Florida — types, sizing, efficiency, brands, cost, and how to choose a contractor.
By the Airo Service HVAC Team · Reviewed by a licensed FL technician · Updated July 1, 2026
Buying a new AC in South Florida comes down to five things: the right type (central, heat pump, mini-split or package unit), correct sizing (a Manual J load calculation, not a guess), efficiency (SEER2), a trustworthy licensed installer, and financing that fits your budget. This guide walks through each. Call (305) 846-0155 for honest, no-pressure help.
A new air conditioner is one of the biggest purchases a South Florida homeowner makes — and in our climate it works harder than almost anywhere in the country. This guide covers everything you need to buy well.
1. Choose the right type of system
- Central AC — the standard for most homes with existing ductwork.
- Heat pump — cools like an AC and adds efficient winter heat; ideal for our mild winters.
- Mini-split (ductless) — perfect for additions, condos, or rooms without ducts.
- Package unit — an all-in-one system, common on rooftops and ground pads.
2. Get the size right
Bigger is not better — an oversized AC short-cycles and leaves your home humid. We use a Manual J load calculation based on your square footage, insulation, windows and sun. See what size a 2,000 sq ft home needs.
3. Understand efficiency (SEER2)
Florida requires at least 14.3 SEER2 on new split systems, and because your AC runs most of the year, a higher rating pays back faster here than up north. Read our plain-English SEER2 guide.
4. Pick a brand you can trust
As a Rheem Pro Partner and an authorized Goodman, Daikin and Trane dealer, we install to manufacturer spec — see our brands page. The installer matters more than the badge on the box.
5. Know the cost — and the financing
Price depends on size and efficiency; we quote every job in writing. We also offer $0-down, 0% financing — see financing options so a new system fits a monthly budget.
6. What a proper installation includes
Honest sizing, complete old-system removal, ductwork evaluation, smart-thermostat setup, permitting handled for you, and a 10-year parts / 1-year labor warranty. That's what separates a lasting install from a callback.
7. Repair or replace first?
If your current system is limping along, run the numbers with our repair-vs-replace calculator before you buy.
8. Choose the right contractor
Look for a licensed and insured Florida HVAC contractor, upfront written pricing, real local reviews, and no high-pressure upsell. Learn about us on our About and Reviews pages, and see where we work on the service area map.

For most homes with ducts, a central AC or heat pump; for condos, additions or duct-free rooms, a mini-split. We'll recommend based on your home.
