Nine months of cooling, three of heat, and storms in between
Your air conditioner in Deltona works almost the entire year. Cooling runs March through November, and on afternoons that hit 91°F the compressor cycles on and off for hours trying to keep up. That long season adds up on the parts that keep the compressor running and the refrigerant moving. Heat only has to cover December through February, and on nights near 50°F it does not work nearly as hard, but 92.9% of homes here heat with electricity, so when the heat strip or the heat pump fails, there is no backup burner to fall back on.
Volusia County has seen 27 damaging wind events over the past ten years, and storms here mean power loss along with wind. Statewide, 38% of households went at least 24 hours without power in 2024. An outage does not just stop your system, it can trip the breaker or the safety switch, and the system will not start again until someone resets it, even after the power is back.

Florida requires HVAC contractors to hold a state license.
That license comes from the Construction Industry Licensing Board. The board tested the contractor before issuing it and keeps a record of who holds one. It covers the contractor, not each job, so the same license applies whether the work is a repair, an install, or a routine service call.
For a repair to your heating and cooling system, that license is what stands behind the person doing the work. The board tested them and can act on their record if something goes wrong. What it does not do is check this particular repair. Nothing in the license itself confirms the work at your house was inspected or signed off by anyone.

- Why is my heat not working?
- Most likely the thermostat, a tripped breaker, or the igniter is the problem. With almost all homes here heating with electricity, a tripped breaker or blown fuse is one of the first things worth ruling out. If the thermostat display is blank or set wrong, that alone can stop the system from calling for heat. When power and settings check out and you still have no heat, the igniter or a safety switch inside the unit is a likely cause, and that calls for a contractor to look at it.
- Why is my system running but not cooling the house?
- The system is running but something between the air and the house is not doing its job. A dirty filter blocks airflow and can make the coil freeze, which stops cold air from reaching your rooms even though the unit sounds like it is working fine. Low refrigerant from a leak will do the same thing, and that only gets fixed by a contractor who can find the leak and recharge the system properly. With afternoons here reaching 91°F, a few hours of reduced cooling shows up fast, so it is worth checking the filter first before assuming the worst.
- What can I check before calling for HVAC repair?
- Check the thermostat, the breaker panel, and the air filter first. Make sure the thermostat is set to heat or cool as needed and has power, since a dead battery or wrong setting looks like a bigger problem than it is. Check the breaker for the system too. After a storm this matters even more, since 38% of Florida households lost power for at least 24 hours in 2024, and a reset breaker is sometimes all it takes. Pull the filter and hold it up to the light. If you can't see through it, replace it. If the system still isn't working after that, a licensed contractor can diagnose what's left.
