Parkville asks a mini-split to run almost year round

Winter nights here average 22°F from December through February, and a mini-split has to keep pulling heat out of air that cold for seven months, October through April. Then it flips over and covers cooling for the five months after that, with afternoons averaging 87°F. That is 12 months of one system carrying the load, with barely a break between heating and cooling.

Any new unit installed now has to meet the federal minimum for split-system heat pumps, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. That is the floor, not a feature, so it is worth knowing before you compare quotes.

Is a mini split worth it?
For most homes, yes, especially in a room that never gets comfortable off the main system. Parkville needs heat or cooling every month of the year, with winter nights averaging 22°F and summer afternoons averaging 87°F, so a system built to handle both jobs from one unit earns its keep. Whether it makes sense for your house depends on what you're heating and cooling now and where the trouble spot is. A contractor can walk through that with you and price the job for your house.
How many rooms can a mini split cover?
A single outdoor unit can run one indoor head or several. Each indoor head heats and cools the room it's mounted in, so a two-room house might use one outdoor unit with two heads, while a larger home could need more heads or more than one outdoor unit. The right number comes down to the size and layout of the space, the insulation, and how many rooms need their own thermostat control. A contractor sizing the job will look at the actual rooms before recommending how many heads to install.
Can a mini split heat a whole house?
It can, if enough indoor heads are placed to reach every room and the system is sized for the cold the house will see. A mini split heats the space it's mounted in rather than moving air through ducts, so a house with an open layout might get by with fewer heads than one with a lot of closed-off rooms. Parkville homes need heat from October through April, so the system has to be sized to carry that full stretch, not just the mild days in it. A contractor can look at the floor plan and tell you how many heads it would take to cover the whole house.
