In Miami-Dade, a heat pump works cooling duty almost every day of the year
Summer afternoons here average 91°F, and homes in Miami-Dade need cooling all twelve months. Winter nights average 59°F from December through February, so the heat pump's heating side rarely has much to do. That is a heavy, year-round load on one side and a light load on the other, and a new system has to be sized for that balance rather than split evenly between the two.
Any split-system heat pump installed new has to meet a federal minimum of 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. In a climate that leans on cooling this hard, that cooling rating is the one doing most of the work all year. Power loss is also worth planning around here. Florida saw 38% of households go without power for 24 hours or more in 2024, and the region has logged 80 damaging wind events over the past ten years.

Florida requires HVAC contractors to hold a state license.
That license comes from the Construction Industry Licensing Board, and it belongs to the contractor, not to any single job. The state tested that contractor before handing it over, and it keeps a record of who holds one. It does not mean a specific installation was checked before, during or after the work.
For a heat pump going in on your property, the state license tells you the contractor is qualified to do the work. What confirms the work itself was done right is the permit and inspection from your local building office, which most cities and counties in Florida require when a heat pump is installed. The license and the inspection are two different things covering two different parts of the job.

- Is a heat pump better than a furnace?
- For Miami, yes, because a furnace is built to solve a problem you don't have here. Winter nights average 59°F, mild enough that a heat pump handles it without strain, and the same unit also runs your air conditioning the other 91°F afternoons of the year. A furnace only heats. A heat pump does both jobs with one system, which is what this climate actually calls for.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only moves heat out of your house. A heat pump can run that same cycle in reverse, pulling heat from outside air and moving it in, so it heats as well as cools. In Miami the cooling side is what gets used most, but on the cooler winter nights the heating side means you are not relying on a separate system for those months.
- Does a heat pump work in cold weather?
- Yes, and Miami winters never test the limits of one. Heat pumps lose efficiency in truly cold air, but winter lows here average 59°F, which is well within the range where a heat pump heats a home easily. The colder climates where heat pumps struggle just are not what you deal with in this area.
