Installed/turnkey, Windermere (Orange County), 2026. Prices are A2L-refrigerant-era and built high on purpose — the on-site pro only trues the number down, never up. Ductwork, electrical-panel, or refrigerant line-set work, if your home needs it, is confirmed on site.
What replacing an AC in Windermere actually involves
Windermere homes around the Butler Chain of Lakes tend to be large, open-plan estates — high ceilings and big glass that pull serious cooling load. Under-sizing here is the common mistake.
- Housing mix
- Much of Windermere's stock is 1990s–2010s custom and luxury construction, often two stories with vaulted, open floor plans.
- Home size
- Estate-scale homes frequently exceed 3,000 sq ft and run zoned multi-system setups — two outdoor units is normal here, not a red flag.
- Cooling reality
- Big glass and high volume raise the load; lakefront humidity makes proper dehumidification matter as much as raw tonnage.
- Permits
- Orange County requires a permit and inspection per outdoor unit replaced; multi-system homes mean multiple line items handled by the contractor.
- Utility
- Windermere-area service is largely Duke Energy Florida; higher-SEER2 Best-tier systems can meaningfully cut bills on a large home.
Florida code, briefly: every new system in Florida must meet the 14.3 SEER2 efficiency floor (the Southeast minimum), and the outdoor unit must be anchored to a hurricane-rated pad or tie-downs to resist wind uplift. All current equipment uses the 2025+ A2L refrigerant — that cost is already in the prices above, never added later.
Five contractors, five numbers, a wasted day off
When an AC dies in a Windermere summer, the usual path is calling around, taking time off work for all-day windows, and getting five different prices you can't compare. The longer a failing system limps, the more an August breakdown costs you. We do it the other way: one real price up front, built high so it only moves down, and one trusted local pro to confirm it — not five salespeople blowing up your phone.

Questions homeowners ask
How much does it cost to replace an AC system in Windermere?
A new central AC system in Windermere runs about $8,600 to $19,500 fully installed in 2026, depending on size and tier. A typical 3-ton home lands around $10,000–$16,000. The size-by-size table above shows every option.
What size AC do I need for my Windermere home?
Square footage gives a rough band, but the only reliable number is the tonnage already installed on your outdoor unit's nameplate. Snap one photo and we read it for you — then we cross-check it against your home size and flag any oversizing so the on-site pro can right-size it down.
Do I need a permit to replace an AC in Orange County?
Yes. Orange County requires a mechanical permit and inspection for a system changeout, and your licensed installer pulls it. An unpermitted, uninspected swap can become a problem when you sell the home.
Should I keep paying for service calls or replace the whole system?
If your system is past about 12–15 years and the service calls are stacking up, replacement usually wins — a new high-efficiency system cuts the power bill, and you avoid a breakdown during a Florida August. The quote weighs system age against what you're spending to keep it limping.
Why is your price sometimes higher than a quick online estimate?
On purpose. We commit to one number built high, so the on-site pro only ever moves it down, never up. A teaser range that climbs once a salesperson is in your living room helps no one.
