Bowie asks a mini-split to work almost year round
A mini-split here spends 11 months a year heating or cooling. Winter nights average 28°F from December through February, and the heating side has to hold up through that stretch. Summer afternoons average 86°F, and the cooling side takes over from June through September. There is not much of the year when the system gets to rest.
Any new mini-split installed today has to meet the federal minimum for a split-system heat pump. That floor is 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. It applies to the equipment itself, not a special ductless rule. Maryland households also lost power for at least a day at an 11% rate in 2024, and a heat pump does nothing for the house while the power is out.

Maryland requires HVAC contractors to hold a state license.
The license belongs to the contractor, not to the job itself, so it does not get reissued for each installation. It means the state has tested this contractor and keeps a record of them. That record is what you are relying on when you hire someone in Prince George's County.
Most cities and counties also require a permit from the local building office for a mini-split installation, with an inspection once the work is done. That inspection checks what was actually installed at your house. The state license tells you the contractor was tested. The permit and inspection tell you the job itself gets checked.

- Is a mini split worth it?
- For the right house, yes. A mini split heats and cools without ductwork, so it works well in additions, converted garages, or older homes that never had ducts run to every room. Bowie needs heat from October through April and cooling from June through September, so a system that handles both jobs earns its keep most of the year. Units sold now have to meet federal minimums for both heating and cooling efficiency, so the question is really whether ductless fits the space, not whether the system is efficient enough.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, depending on the system. A single-zone system covers one room or open area. A multi-zone system ties one outdoor compressor to multiple indoor heads, each with its own thermostat, so different rooms can run at different temperatures at the same time. How many zones a house can support comes down to the size of the outdoor unit and the layout of the home, which a contractor works out room by room.
- Can a mini split heat a whole house?
- It can, if it's sized and placed for that. A multi-zone system with enough indoor heads can heat every room, the same way a furnace or central heat pump does, just without ducts. Bowie sees winter nights averaging 28°F from December through February, so the system has to be sized to keep up on the coldest nights, not just handle mild weather. Whether whole-house coverage makes sense for a particular home depends on its layout and how many zones it would take, which a contractor can work out after seeing the place.
