This is not our price
Every figure on this page is a third-party market range, sourced and dated below. It is here so you can sanity-check a quote, not so you can hold us to it. For a number that is ours, ask us to look at the actual system.
Size the job to this city's houses, not to a national average
Seminole County Property AppraiserNational cost guides quote by tonnage. That is not how the published Central Florida sources quote it, and it is not how a house in Altamonte Springs prices out either.
What is on the record is the size of the stock. The median improved residential parcel in this city has 1,325 sq ft of living area — small, because 61.65% of the city's units are multi-family. A 712 sq ft condo at Lakewood Park and a 1,849 sq ft house in Spring Oaks are not the same job and should not land in the same third of that range.

Condo changeout, house changeout
The split runs through the priceThe equipment is smaller and there is no attic labour, which pulls the number down. Three things pull it back up.
- Association approval for the condenser location, in writing, before anything is ordered
- A secondary drain pan and float switch protecting the unit below yours
- Line sets that cross common elements, which is the association's property, not yours
A 1970s or 1980s house is the common case here and it is where the scope grows past the equipment.
- Attic platform and drain pan, often original
- Duct condition — the trunk line is frequently the same age as the house
- Electrical disconnect and whip
- Strip heat to a heat pump: the largest published Duke tier, and most of this stock qualifies
Take the rebate off the end
Duke EnergyBefore you compare any of these numbers, read the rebate order of operations. Duke Energy requires a free Home Energy Check completed within the previous 24 months before the equipment is installed. Replace first and apply afterwards and the rebate is denied — up to $1,000 on the tier that fits most of this city.

Duke Energy publishes these amounts. The page they come from is not scoped to a single state — its body also references the Carolinas, Ohio, Kentucky and Indiana. The Florida application portal confirms the program and the Home Energy Check prerequisite apply to Duke Energy Florida, but no Florida-scoped statement of these specific dollar figures was located. Rebate amounts change. Every figure here is dated, and Duke Energy on 800.254.8535 is the only authority on what is payable today.
