Eleven months of work for your heat pump in Gulfport
Winter nights here average 42°F, mild enough that a heat pump barely has to work to keep up. Summer afternoons are a different story, averaging 90°F across the six months of cooling season from May through October. Add the five months of heating from November through March and your heat pump is running nearly all year, with only a few weeks of rest in between.
A new split-system heat pump installed today has to meet federal minimums of 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. With summers like Gulfport's, the cooling side of that rating is what gets tested most. Most homes here heat with electricity, so when the power goes out, it takes the heat pump down with it, and it should come back on by itself once the power is back.

Mississippi requires HVAC contractors to hold a state license.
The license belongs to the contractor, not to this particular job, so it follows them from one house to the next rather than getting issued fresh for your heat pump. It is the state's record of who is allowed to do this work, kept by the State Board of Contractors.
For the installation itself, that license is what stands behind the work. Most cities and counties in Mississippi also require a permit for a heat pump installation, with an inspection once the work is finished, so the job gets a second, separate check from the local building office.

- Is a heat pump better than a furnace?
- It depends on what you're weighing. A heat pump handles both heating and cooling from one system, where a furnace only heats, so you'd still need a separate air conditioner. Gulfport needs cooling six months a year and heat five, so a system that does both can make sense here. Winter nights average 42°F, which is well within the range a heat pump handles without trouble. A furnace burns gas or uses electric resistance and tends to put out hotter air at the vent, which some people prefer, but it can't cool your home in summer.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only cools. A heat pump does the same job in summer, moving heat out of your home, but it can also run in reverse and move heat into your home in winter. Mechanically the two are close cousins, both using a compressor and refrigerant to move heat rather than generate it. The difference shows up in November, when your air conditioner would sit idle and your heat pump switches over to keep the house warm.
- Does a heat pump work in cold weather?
- Yes. A heat pump pulls heat from the outside air even when it's cold outside, since air still holds heat well below freezing. Gulfport's winter nights average 42°F, which is mild for this kind of system, so a heat pump here doesn't face the kind of extreme cold that pushes some units toward their limit. Newer heat pumps sold since January 2023 have to meet a federal minimum of 7.5 HSPF2 for heating, a rating that reflects how they perform across a range of outdoor temperatures, not just on a mild day.
