Deltona runs its system almost year round
Cooling season here runs March through November, nine months of the year. Summer afternoons average 91°F, so the compressor is the part doing most of the work, most of the year. Winter is short, just December through February, with nights averaging 50°F. That's mild enough that a heat pump can handle both jobs without a backup furnace.
Most homes in Florida heat with electricity, and a new system sized for this climate needs to move heat both ways efficiently. Storms are part of the picture too. Volusia County has seen 27 damaging wind events over the past ten years, and in 2024, 38% of Florida households lost power for at least 24 hours. Whatever gets installed here needs to hold up to that and come back on its own when the power does.

Florida requires HVAC contractors to hold a state license.
Florida licenses HVAC contractors through the Construction Industry Licensing Board. That means the state tested the contractor and keeps a record of them. The license covers the contractor as a business, not any single job, so the same license that qualifies them to install your system covers every other installation they take on.
For a job like this, that license is what stands behind the contractor doing the work. In most cities and counties here, putting in a new furnace, air conditioner or heat pump also needs a permit from the local building office, with an inspection once the work is done. That permit and inspection come from the county or city, separate from the state license itself.

- 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. Most homes here run cooling nine months a year, March through November, so a struggling system gets tested hard and often. If a contractor keeps coming out for the same unit, or the parts it needs are getting hard to find, replacement usually makes more sense than another repair. Age alone isn't the deciding factor. How well it's still running is.
- Should I replace my furnace and air conditioner at the same time?
- If both are original to the house and close in age, replacing them together is usually the better move. A furnace and air conditioner installed at the same time are matched to work with each other, which affects how efficiently the system runs and how evenly it heats and cools. Homes here only need heat three months a year, December through February, while the air conditioner runs the other nine. If the furnace is still in good shape, a contractor can tell you whether it's worth keeping or replacing alongside the air conditioner.
- What happens during an HVAC installation?
- A contractor removes the old equipment, then sets the new furnace or air handler and outdoor unit in place. The refrigerant lines, ductwork, and electrical connections get tied into the new equipment, and the system is checked for proper refrigerant charge and airflow before it's turned over to the homeowner. The contractor also confirms the thermostat is communicating correctly with the new system. In Florida, any contractor doing this work is required to hold a state license issued by the Construction Industry Licensing Board, so it's worth confirming that before work starts.
