Your heat pump runs almost the whole year here
Port St. Lucie asks for cooling eleven months a year and heat for barely one. That means the system is almost always in cooling mode, and the compressor and outdoor fan rarely get a real rest. Summer afternoons averaging 90°F push the outdoor unit hard, day after day, and that steady load is what wears down a compressor or a run capacitor over time.
Most homes here heat with electricity, so when the heat pump falters on a cold snap night, there is no backup furnace to lean on. Florida also sees its share of power interruptions, and after an outage a heat pump should restart on its own. If yours does not, or if it is blowing warm air on a hot afternoon instead of cool, that is worth a look before the next stretch of 90-degree days.

Florida requires HVAC contractors to hold a state license.
The state tested this contractor before handing out that license, and the Construction Industry Licensing Board keeps a record of who holds one. That license belongs to the contractor, not to any single job, so it stands behind the work whether it is a heat pump, a furnace, or a water heater.
A heat pump repair usually means opening the refrigerant side of the system, and federal law requires whoever does that to hold EPA Section 608 certification, no matter what state they work in. That certification is separate from the Florida license. One says the contractor was tested and is on record with the state. The other says the technician handling the refrigerant is trained to do it without releasing it into the air.

- Why is my heat pump blowing cold air?
- In cooling mode this is normal, that's the job it's doing. But if you're in a stretch of cool nights and the air coming out feels cold instead of warm, the system may be stuck in cooling mode or the reversing valve isn't switching over. It's also worth checking the thermostat setting before anything else, since a mode set wrong will cause exactly this.
- Why is there ice on my heat pump?
- A thin layer of frost during a cold snap can be normal, and the unit should run a defrost cycle to clear it on its own every so often. If the coil is caked in ice instead of light frost, or the ice isn't melting between cycles, the defrost cycle isn't working or airflow across the coil is blocked. Check that nothing is stacked against the outdoor unit and that the fan is actually spinning. If the ice keeps building, a contractor needs to look at the defrost control and the sensor that tells it when to run.
- Why is my heat pump running but not cooling?
- The outdoor unit is running but the refrigerant isn't moving heat the way it should, and a few things cause that. A dirty filter or blocked return can starve the system of airflow, so check that first since it's the easiest to fix yourself. If the filter is clean and the vents are open, the problem is likely low refrigerant from a leak, a failing compressor, or a stuck reversing valve, and those need a licensed contractor to diagnose.
