Sanford asks a heat pump to cool more than it heats
Your heat pump earns its keep in the nine months of cooling, March through November, when afternoons average 92°F. Heating only runs December and January, and winter nights average 51°F, mild enough that the system rarely has to work hard to keep up. This is a machine bought mostly to cool, sized and chosen with that in mind.
A new split-system heat pump has to meet federal minimums of 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. In Seminole County that cooling number matters more than the heating one, given how the season splits. Worth asking too how the unit holds up outside the box rating. Florida saw 30 damaging wind events over the past ten years, and 38% of households went at least a day without power in 2024. A heat pump that comes back on by itself once power returns is one less thing to think about after a storm.

Florida requires HVAC contractors to hold a state license.
The license is held by the contractor, not issued per job, so it covers the business doing your installation rather than this specific heat pump. The Construction Industry Licensing Board is the body that tested and records that contractor, and that record is what stands behind the work.
In most cities and counties, installing a heat pump needs a permit from the local building office and an inspection once the work is done. That inspection is separate from the state license. It is the check on how the unit was actually installed at your address.

- Is a heat pump better than a furnace?
- For Sanford, yes, because a heat pump handles both heating and cooling and this area needs cooling nine months out of the year. A furnace only heats, and your winters here are short and mild, averaging 51°F on winter nights. A heat pump moves heat instead of burning fuel to make it, so it covers your two months of heating and your long cooling season with one system. Most homes here already run on electric heat, so a heat pump is doing a job the house is already set up for.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only cools. A heat pump does the same cooling job in summer, but it can also run in reverse to heat the house in winter. Inside, the two work the same way, moving heat from indoors to outdoors when you need cooling. The difference is the reversing valve that lets a heat pump send that heat the other direction when it turns cold.
- Does a heat pump work in cold weather?
- Yes. A heat pump pulls heat from outside air even when it feels cold outdoors, and Sanford winters are mild enough that this is rarely a concern. Winter nights here average 51°F, well within the range a heat pump handles without strain. Federal rules now require new split-system heat pumps to meet 7.5 HSPF2 for heating, so any new unit installed is built to perform through winters like this one.
