Researched market estimates gathered on 6 September 2026 from third-party cost guides (hvac.com Florida replacement guide dated 8 April 2025, Angi Orlando install guide, HomeGuide, This Old House) and one publicly advertised Lake Mary competitor price list. These are not our prices, they are not a quote, and they are not verified against any Lake Mary invoice. Ranges from commercial cost-guide sites run wide for a reason. They are not our prices, not a quote, and no figure on this page should be treated as one.
The line item nobody else prints
The line item that is genuinely local: inside the City of Lake Mary the mechanical permit for a changeout is 0.75% of the documented mechanical valuation, $35 minimum. On a $9,000 changeout that is about $68; on a $12,000 job about $90. If your address is in Heathrow, Heathrow Woods or another unincorporated pocket of ZIP 32746, the permit is a Seminole County permit on a different schedule.
Most contractor pages write “permit included” and stop. Two homes a mile apart with the same 32746 mailing address can file with two different building departments, on two portals, with two fee schedules and two inspection-scheduling deadlines. That is worth asking about before you sign, not after. Which desk your address answers to ›
What actually moves the number in this city
- Pool homes. 2,378 of 5,343 improved residential parcels in the City of Lake Mary tax district have a pool — 44.5%, the highest share of the seven Seminole County cities measured. Pool houses are the ones with the big sliding-glass span onto the lanai, and glass is load. Why that changes the equipment ›
- Attic ductwork. The median City of Lake Mary house was built in 1996 and a quarter in 1988 or earlier. Duct systems of that vintage are at or past service life, and replacing them adds roughly $2,500–$6,000 on top of the equipment.
- Multiple systems. Heathrow Woods homes run 4,147–7,240 sq ft. Two or three air handlers on one house is normal there, and a single-tonnage quote for such a house is a red flag rather than a bargain.
- Refrigerant. New equipment ships on R-454B or R-32 rather than R-410A. A failed R-410A outdoor unit cannot be paired with a new R-454B one, which is how a compressor repair turns into a whole-system price. What the transition means ›
- Rebate, at the end. Duke Energy publishes tiers from $300 to $1,000, but only if a free Home Energy Check was completed in the previous 24 months. The prerequisite that voids most claims ›
Three quotes, compared line by line
The reason to publish ranges at all is so that a homeowner can tell a fair quote from an unfair one. The range does not do that on its own — a $9,000 quote and a $12,000 quote for the same house can both sit inside the researched band and only one of them includes the ductwork, the permit and a load calculation.
Get three written quotes and compare them on the six lines that make them comparable: tonnage, SEER2, whether a Manual J was performed on your house, duct condition, permit and authority, and warranty terms stated separately. The printable checklist ›
