Your heat pump runs every month of the year here
In Miami-Dade there's no winter break. Summer afternoons average 91°F and the system answers to that heat 12 months a year, with compressor and fan running far more hours than a heat pump would ever see somewhere with a real winter. That kind of runtime wears on the compressor and the fan motor before their time, and a system that never gets a season off has less room to hide a problem before it shows up as warm air coming out of the vents.
Most homes here heat with electricity, so when the outdoor unit trips out or the compressor gives out, there's no backup keeping the house comfortable. And with 80 damaging wind events recorded in the county over the past ten years, plus more than a third of Florida households losing power for at least a day in 2024, the outdoor unit takes a beating from storms on top of the heat. Debris and wind-driven rain get into the cabinet, and a unit that loses power hard during a storm doesn't always come back on the way it should.

Florida requires HVAC contractors to hold a state license.
The Construction Industry Licensing Board tests contractors before it licenses them, and it keeps a record of who holds one. That license belongs to the contractor, not to any single job. It stands behind the person coming to your house whether the work is a heat pump repair, a new install, or something else.
A heat pump repair almost always means opening the refrigerant side of the system. Federal law requires anyone who does that to hold EPA Section 608 certification, no matter what state they work in. In Florida that certification sits alongside the state license rather than replacing it. The license says the contractor was tested and is on record with the state. The certification says the technician handling refrigerant was trained to do it without venting it into the air.

- Why is my heat pump blowing cold air?
- In Miami this usually means the heat pump is doing exactly what it is set to do, since almost every system here runs in cooling mode year round. If you actually want warm air and are getting cold, check that the thermostat is set to heat and not fan only. When it is set correctly and still blows cold, the reversing valve that switches the system between heating and cooling may be stuck, and that calls for a contractor to look at it.
- Why is there ice on my heat pump?
- Ice on the outdoor unit means airflow across the coil is restricted somewhere. A dirty air filter, a coil caked with dirt, or a refrigerant leak can all cause this, since low refrigerant drops the coil temperature below freezing. Turn the system off and let the ice melt before a contractor checks it, because running it iced up can damage the compressor. Do not chip at the ice yourself.
- Why is my heat pump running but not cooling?
- If the outdoor unit and indoor blower are both running but the air is not cold, the most common cause is low refrigerant from a leak. A dirty filter or a coil blocked with dirt can also cut off enough airflow that the house never cools down even though the system runs constantly. A contractor can check refrigerant charge and airflow to find which one it is.
