Eleven months of work for your mini-split
Holland asks for heat or cooling almost year round. Winter nights average 20°F from December through February, and a mini-split has to keep pulling heat from air that cold for eight months, October through May. Then summer afternoons average 81°F and the same system switches to cooling for June through August. There is barely a month off in between.
A new mini-split installed here has to meet the federal minimum for a split-system heat pump, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, if it was built on or after January 1, 2023. Given how many months it runs, that heating rating matters as much as the cooling one.

Michigan requires HVAC contractors to hold a state license.
The license is issued to the contractor, not to this specific job. It means the state has tested and recorded the person or company you hire, and that record stays with them from one installation to the next.
For a mini-split installation, that license is what stands behind the work. Most cities and counties also require a permit from the local building office for this kind of job, with an inspection once the installation is done, so check whether that applies where you are.

- Is a mini split worth it?
- For the right room, yes. A mini split heats and cools one space well without ductwork, and it runs on a heat pump, so it does both jobs with one system. Holland winters get cold, down to 20°F on average on winter nights from December through February, so check that any unit you're looking at is rated to keep working at those temperatures. A contractor can tell you if a mini split fits the room you have in mind or if your situation calls for something else.
- How many rooms can a mini split cover?
- A single outdoor unit can run up to eight indoor heads, each one serving its own room. This is called a multi-zone system, and each head has its own thermostat, so you can heat or cool only the rooms in use. The right number for your house depends on the size and layout of the rooms and the capacity of the outdoor unit, which is something a contractor works out room by room.
- Can a mini split heat a whole house?
- It can, if you install enough indoor heads to reach every room. A multi-zone mini split can heat a whole house the same way a furnace does, just with one head per room or per zone instead of ducts. Holland homes need heat eight months of the year, October through May, so the system has to be sized for winter nights that average 20°F. That is a job for a contractor to size correctly, since an undersized system will run constantly and still fall short on the coldest nights.
