Montgomery asks for eleven months of run time
A mini-split in Montgomery works most of the year. Homes here need cooling from May through October, six months, with summer afternoons averaging 91°F. Then heat takes over from November through March, with winter nights averaging 38°F. Only one month sits free of either load.
Any mini-split installed new has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, the federal minimum for split-system heat pumps. That is the same standard whether the unit runs six months of the year or year round, so it applies here.

Alabama requires HVAC contractors to hold a state license.
The license comes from the Alabama Board of Heating, Air Conditioning & Refrigeration Contractors. It covers the contractor as a business, not each job that contractor takes on. There is a record of that contractor on file with the state, but no board inspector comes out to look at this particular installation.
For the mini-split going in on this job, that check comes from the local building office instead. Most cities and counties require a permit for this kind of installation, and an inspection once the work is done. That inspection is what looks at the actual unit, the wiring and the line set. The state license is what stands behind the contractor. The permit and inspection are what stand behind this job.

- Is a mini split worth it?
- For the right house, yes. A mini split handles both heating and cooling from the same outdoor unit, which matters here since homes need one or the other 11 months of the year. It also skips the ductwork, so a room that never got even heat or air before can get its own thermostat and its own comfort. Whether it makes sense for your house depends on how it's built and what's heating it now, so a contractor should walk through that with you.
- How many rooms can a mini split cover?
- It depends on the system, but one outdoor unit can run several indoor heads at once. Each head is sized to the room it serves, so the right number comes down to square footage, ceiling height, and how the rooms are laid out. A contractor can look at the house and tell you how many heads it actually needs.
- Can a mini split heat a whole house?
- It can, if it's sized and placed for that job. A mini split with enough indoor heads, one in each main room, can carry a house through winter here without a furnace or boiler running alongside it. Winter nights average 38°F here, so the system has to be matched to that cold rather than to a mild climate. Getting it right depends on how the house holds heat and where the heads go, which is something a contractor needs to see in person.
