Eleven months of work for a Georgetown mini-split
Your mini-split will run almost year round here. Cooling from May through October, when summer afternoons average 89°F, then heat from November through March, when winter nights average 38°F. Only one month sits idle. Whatever gets installed needs to hold up to that kind of use.
Any new split-system heat pump, ductless included, has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating under the federal minimum that took effect in 2023. That's the floor a licensed installer has to work from when sizing your new unit for a Georgetown County home.

- Is a mini split worth it?
- For most homes in Georgetown, yes. You get 11 months a year where the system is either heating or cooling, so a unit that does both from one outdoor condenser earns its keep. It also skips the ductwork, which matters if the room you're adding it to was never connected to a central system. A mini split installed on or after January 1, 2023 has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, so a baseline level of efficiency comes with the system rather than something you have to shop for separately.
- How many rooms can a mini split cover?
- A single outdoor condenser can run one indoor head or several, depending on the system. Each indoor head is sized and placed for the room it serves, so a contractor will look at the square footage and layout of your house before saying how many zones make sense. A one-room addition needs a different setup than a house where you want separate control in multiple rooms.
- Can a mini split heat a whole house?
- It can, if there are enough indoor heads placed to reach every room. Winter nights in Georgetown average 38°F from December through February, well within what a heat pump handles, so cold isn't the obstacle. Coverage is. A single head warms the room it's in and whatever space is open to it, not rooms behind closed doors down a hallway. A contractor can walk the house and tell you what it would take to cover all of it.
