Ten months a year, your mini-split is the only thing running
Prattville asks for cooling from May through September, when afternoons average 91°F, then asks for heat from November through March, when nights average 37°F. That leaves ten months where the compressor is working in one direction or the other, and only two months where it can rest.
A new system installed here has to hold up on both ends of that. Units built since January 2023 have to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, and with the heat pump running most of the year in Prattville, that heating number carries as much weight as the cooling one. 57.6% of homes here heat with electricity, so for most of Prattville the mini-split is not backup heat. It is the heat.

Alabama requires HVAC contractors to hold a state license.
The Alabama Board of Heating, Air Conditioning & Refrigeration Contractors issues that license, and it covers the contractor, not the individual job. The state tested this contractor and keeps a record of them, apart from whatever happens on your mini-split install.
For this job, that license is the main protection you have, since Autauga County falls under Alabama's licensing. Beyond that, most cities and counties in Alabama require a permit from the local building office for an installation like this, along with an inspection once the work is done.

- Is a mini split worth it?
- For the right room or addition, yes. A mini split heats and cools one space well without ductwork, and it runs on electricity, which is how most homes here already heat. Winters average 37°F and summers 91°F here, so the unit has real work to do most of the year, not just a few mild weeks. Whether it makes sense for your house depends on what you're heating and cooling and what's there now, which is something a contractor can walk through with you.
- How many rooms can a mini split cover?
- A single-zone system covers one room or open area. If you need more than one space conditioned, a multi-zone system connects several indoor units to one outdoor condenser, each with its own thermostat. The right number of zones depends on how your house is laid out and where the heat gain or loss actually happens, so a contractor should size it room by room rather than guess at a number.
- Can a mini split heat a whole house?
- It can, if enough zones are installed to reach every room. Homes here need heat from November through March, so whatever system you choose has to keep up on the coldest nights, not just take the edge off. Whole-house coverage with a mini split means sizing each indoor unit to its room and making sure the outdoor unit can handle all of them running at once, which is a job for a contractor to calculate against your specific house.
