Moab asks a mini-split to run almost all year
Winter nights here average 20°F from December through February, and summer afternoons average 89°F. Homes need heat from October through May and cooling from June through August, which leaves only one month when a mini-split gets a break. That is 11 months of work a year, so the unit going in needs to hold up on both ends, the cold nights and the hot afternoons.
A mini-split is a split system under federal rules, so any unit made from 2023 on has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. With most homes here on gas heat, a mini-split is often filling in the cooling season or covering a room the main system does not reach, so it needs to be sized for a 20°F night and an 89°F afternoon, not just one or the other.

Utah requires HVAC contractors to hold a state license.
The license is held by the contractor, not tied to this one job. Utah tests the contractor and keeps a record of them through the Division of Professional Licensing. There is an exception to know about. Work under $7,000 does not need a licensed contractor, and a mini-split installation can fall on either side of that line depending on the equipment and the scope of the job.
In most cities and counties, a mini-split installation needs a permit from the local building office, with an inspection once the work is done. That inspection is separate from the state license and stands whether or not the job happens to fall under the $7,000 threshold.

- Is a mini split worth it?
- For most homes it is, especially where the coldest nights sit near 20°F and the system has to carry both heating and cooling. A mini split is a heat pump, so it does both jobs with one outdoor unit instead of running a furnace all winter and a separate air conditioner all summer. Here the heating side is doing real work, since homes in Moab need heat from October through May. Whether it makes sense for a particular house still depends on the layout and what heating is already in place, and a contractor can walk through that for your home.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, depending on the model. Single-zone systems cover one room or open area well. Multi-zone systems tie two, three, or more indoor heads to one outdoor unit, with each head controlling its own room. How many zones a given house needs comes down to square footage, layout, and how the rooms are used, so a contractor sizing the job will look at the house room by room rather than guess from the outside.
- Can a mini split heat a whole house?
- Yes, if it's sized and laid out for the whole house rather than just one room. A multi-zone mini split can put an indoor head in each main room and heat the entire place, and because it's a heat pump it keeps working through the cold months, not just as a supplement. With winter lows here averaging 20°F, the system has to be sized for that low end, not just for a mild day. Getting the zone count and capacity right for the actual house is a job for a contractor who can look at the space directly.
