What a mini-split here has to handle
Lansing asks a mini-split to work most of the year. Homes here need heat from October through May and cooling from June through August, so the system runs 11 months out of 12. Winter nights average 19°F, cold enough that the heat pump side has to keep working when there is little warmth left in the outside air to pull from. Summer afternoons average 80°F, a lighter load than what the unit sees all winter.
Any mini-split installed new has to clear the federal minimum for a split-system heat pump, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. A licensed installer sizes the unit to your home starting from that floor.

Michigan requires HVAC contractors to hold a state license.
The license is issued to the contractor by the Board of Mechanical Rules, and it stays with them across every job, not tied to any single address or install. It means the state tested this contractor before letting them work on your equipment, and there is a record of that behind the name on your quote.
For a mini-split install, that license is what backs the person doing the work, and the local building office is what backs the job itself. In most cities and counties, putting in a mini-split needs a permit and an inspection once the work is done, so someone outside the contractor looks at the line set and the electrical connection before the job is called finished.

- Is a mini split worth it?
- For most homes here, yes, especially if you're heating or cooling a room your furnace or central air doesn't reach well. A mini split gives you a heat pump that handles both jobs in one unit, and with winter lows averaging 19°F, cold-climate models are built to keep working when the temperature drops. It won't replace a furnace in most homes, but as a way to condition an addition, a garage, or a room that's always too hot or too cold, it earns its keep.
- How many rooms can a mini split cover?
- A single-zone mini split heats and cools one room or open area. If you need more rooms covered, a multi-zone system runs several indoor units, each in its own room, off one outdoor unit. A contractor will look at the size and layout of the rooms you want conditioned and size the system to match, since a unit that's too big or too small for the space won't run efficiently.
- Can a mini split heat a whole house?
- It can, but a whole-house system means an indoor unit in enough rooms to cover the house, not just one or two. With homes here needing heat from October through May, that's a lot of months for a system to carry the full load on its own, so most homeowners use a mini split to cover specific rooms instead. If you're considering whole-house coverage, a contractor can walk through the house and figure out how many zones it would take.
