In Kissimmee, cooling is the year-round job
Your new system will run almost every month of the year here. Summer afternoons average 91°F, and that heat stretches from February through December. January is the only month that asks for heat, and even then nights average just 52°F. The unit you install is built to spend nearly all its life cooling, not heating.
Most homes here run on electric heat, so when the power goes out, the whole system stops, heat and air both. Osceola County has seen 14 damaging wind events over the past ten years, and across Florida, over a third of households lost power for at least a day in 2024. A new install is a chance to plan for that, not just for the heat.

Florida requires HVAC contractors to hold a state license.
The license is issued to the contractor's business, tested and put on record by the Construction Industry Licensing Board, and it does not expire once the crew shows up. It covers who is allowed to do the work, not any single job, so the same license that qualifies a contractor for this installation qualifies them for the next one too.
For a system replacement in Osceola County, that license is what stands behind the person doing the work, but the installation itself still goes through the local building office. Most cities and counties require a permit for a new furnace, air conditioner or heat pump, along with an inspection once the work is finished. That inspection is what checks the installation itself, separate from the license that qualifies the contractor to do it.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they're worth, or when the system can't keep up on the hottest afternoons anymore. A unit running cooling eleven months a year here wears out faster than one that gets a real break. If a contractor has been out for the same problem more than once, or the unit is old and needs a major part like the compressor, replacing it usually makes more sense than fixing it again. Watch for higher electric bills too, since a system losing efficiency will run longer to do the same job.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, because they were likely installed together and will wear out around the same time. Homes here run cooling nearly every month of the year and only need heat in January, so the air conditioner does the heavy work and tends to show its age first. A furnace or heat strip that barely runs can still have years left in it even after the outdoor unit fails. A contractor can check the condition of both and tell you whether replacing one now and the other later is reasonable, or whether they should go together.
- What happens during an HVAC installation?
- A contractor removes the old equipment, checks the ductwork and electrical connections, then sets the new indoor and outdoor units in place. They connect the refrigerant lines, wiring, and ductwork, then charge the system with refrigerant to the manufacturer's specification. Once it's running, they test airflow, temperature drop, and thermostat operation to confirm everything works as it should. Florida requires the contractor doing this work to hold a state license through the Construction Industry Licensing Board, so it's worth confirming that before work starts.
