AC repair & HVAC contractors in Casselberry
Casselberry sits in Seminole County about 10 miles north of downtown Orlando, and it is a city built around water. It has over 30 lakes and ponds, with Lake Howell the largest, and Lake Concord Park is home to the Casselberry Art House. For HVAC, that matters because the problem in a lake city is moisture first and heat second: a system that cools the air but leaves it damp, or a condensate line that quietly backs up.
A city of lakes is a humidity problem
Orlando-area rainfall averages about 51 inches a year, mostly June through September, and 90°F days typically run from early April into mid-October. Casselberry is part of the same Orlando metro, so that is the cooling season to plan around.
UF/IFAS Extension notes that an air conditioner doubles as a dehumidifier, pulling moisture off the coil and draining it away, and that a properly sized, well-maintained system is what keeps indoor humidity in check. It suggests keeping relative humidity around 55% or lower to limit mold and damage to furniture and building materials.
That is why UF/IFAS lists keeping condensate drain lines clean as a basic practice for Florida homes. The drain is where all that removed moisture leaves the house, so a neglected line works against the whole point of the system. If your system is old enough that the drain line has never been looked at, ask about it during any service visit.

What a Casselberry job costs
A July 2026 Florida pricing guide puts a typical 3 to 4 ton replacement in Orlando and Central Florida at $7,000 to $11,500 installed. For a 2.5 to 3 ton system, the same guide shows $6,000 to $9,200 at the 14.3 SEER2 code minimum, $7,500 to $10,800 at 16 to 17 SEER2, and $9,500 to $13,000 at 18+ SEER2, assuming existing ductwork is in good condition.
Electrical work can add $300 to $1,500 in older homes, and the guide says new or repaired ductwork adds several thousand dollars. These are Florida-wide figures from a pricing site, not Casselberry quotes.
A flat HVAC permit fee, through the city's portal
Casselberry's Building Division publishes a Schedule of Building Permit Fees that lists a $200 flat fee for HVAC, electric, plumbing and gas permits, along with a $100 plan review fee and a $100 inspection fee, with the initial plan review and inspection fees due in full at application. The schedule does not say whether the plan review fee applies to a straight A/C swap, and we could not confirm it, so ask the city or your contractor before assuming either way.
Residential applications go through the city's Building Permit Portal, or on paper at City Hall at 95 Triplet Lake Drive. The city's FAQ says to allow a minimum of five to seven business days for residential permits, so build the permit into your timeline. Inspection results appear in the same portal.

Common questions
How much is an HVAC permit in Casselberry?
The city's published schedule lists a $200 flat fee for HVAC permits, plus a $100 plan review fee and a $100 inspection fee. It does not say whether plan review applies to a simple A/C swap, so confirm the total on your permit invoice.
How long does a Casselberry residential permit take?
The city's FAQ says to allow a minimum of five to seven business days for residential permits, so plan for the permit to be part of your timeline rather than an afterthought.
Why do condensate drain lines matter in a lake city?
The drain carries the moisture your AC removes out of the house. UF/IFAS lists keeping condensate drain lines clean as a basic way to keep indoor humidity down, which is the whole job of an AC in this climate.
