A heat pump here runs almost every day of the year
Port St. Lucie barely gets a winter. Nights average 55°F from December through February, and the rest of the year your heat pump is working the other side, cooling homes through afternoons that average 90°F. Eleven months of cooling and one month of heat means the system almost never gets a rest, and the compressor is what carries that load.
A new split-system heat pump installed here has to meet the federal minimum of 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. With this much cooling demand, the cooling side of that rating matters more than it would somewhere with a real winter. Storms are part of the picture too. St. Lucie County has logged 13 damaging wind events over the past ten years, and with over a third of Florida households losing power for a day or more in 2024, it's worth asking how your new system handles a restart once power comes back.

Florida requires HVAC contractors to hold a state license.
The state license comes from Florida's Construction Industry Licensing Board, and it covers the contractor, not each job. It stays tied to the contractor for the next installation and the one after that, not just this one.
For this job, that license is the thing standing behind the work. On top of it, most cities and counties in Florida require a permit before a heat pump goes in, and an inspection once it's done. The permit means the local building office knows the work is happening. The inspection means someone checks it before it's called finished.

- Is a heat pump better than a furnace?
- For Port St. Lucie, yes. A furnace only makes heat, and this area barely needs it, heat is only called for in January. A heat pump handles that little bit of heating and also covers the cooling this area needs the rest of the year, all from one system. A furnace paired with a separate air conditioner means two systems to maintain instead of one.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only moves heat out of the house. A heat pump can do that same job in summer, then reverse itself and move heat into the house in winter. The parts inside are much the same, the difference is a reversing valve that lets the heat pump run in both directions. In a place like this with 11 months of cooling and only one month of heat, that reversing valve is the whole reason to pick a heat pump over a plain air conditioner.
- Does a heat pump work in cold weather?
- Yes, and in this area that is rarely even tested. Winter nights here average 55°F, which is mild, a heat pump pulls heat from outside air easily at that temperature. Heat pumps lose efficiency as the outdoor air gets much colder, but Port St. Lucie winters don't reach the range where that becomes a concern.
