Your air conditioner never gets a break here
In Miami-Dade, the system runs all twelve months. There is no season where it sits off waiting for spring. Summer afternoons average 91°F, and the compressor works its hardest right when everyone in the house is asking the most of it. That kind of steady load wears on the compressor and the capacitor that gets it started, and both tend to fail on the hottest afternoons rather than the mild ones.
Winter here does not bring much rest either. Nights average 59°F from December through February, mild enough that heat rarely runs. Most homes lean entirely on electricity to stay comfortable, so when the power goes out, the whole system goes down with it. Florida saw 38% of households lose power for at least 24 hours in 2024, and Miami-Dade has counted 80 damaging wind events over the past ten years. After a storm knocks the power out, the system needs to come back on and pick up right where it left off.

Florida requires HVAC contractors to hold a state license.
The license comes from the Construction Industry Licensing Board, and it covers the contractor, not the job. It belongs to the person or company doing the work, and it stays with them from one house to the next rather than being issued fresh for each repair.
For a repair on a heating and cooling system, that license is what stands behind the work in Florida. There is no separate state credential tied to this particular job. The license itself is the record the state keeps.

- Why is my heat not working?
- Almost nothing in Miami is set up to heat a home, so if warm air stopped coming out, look at what's actually installed before assuming a repair. Most houses here cool with a heat pump or straight AC and have no furnace at all. If yours is a heat pump, check that the thermostat is actually set to heat and not just a lower cool temperature, since on mild nights it's easy to have the mode wrong without noticing. If there's a real heating problem and it's tripped a breaker or won't respond to the thermostat at all, a contractor can look at the reversing valve or the strip heat, since those are the parts specific to a heat pump that a straight AC system doesn't have.
- Why is my system running but not cooling the house?
- The system is moving air but not pulling heat out of it, and a few things cause that. A dirty filter chokes airflow across the coil, so start there since it's the one thing you can check yourself. If the filter is clean, the coil itself may be frozen over from low refrigerant or restricted airflow, and a frozen coil stops cooling even though the blower keeps running. It could also be low refrigerant from a leak, which a licensed contractor has to diagnose and recharge, since refrigerant work in Florida requires a state license.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it's set to cool, the temperature is actually below room temperature, and the batteries aren't dead. Next, look at the filter and hold it up to a light. If you can't see light through it, replace it, since a clogged filter alone can make a system run without cooling. Then check the breaker panel and any disconnect switch near the outdoor unit, since a tripped breaker or a switch that's been bumped off will stop the system cold with no other symptoms. If none of that explains it, a licensed contractor will need to look at the refrigerant charge or the electrical components inside the unit.
