Vernal asks a mini-split to run nearly all year
Nine months of heat, September through May, then two months of cooling in July and August. Eleven months out of the year, your mini-split is the thing keeping the house comfortable. Winter nights averaging 13°F put real load on a heat pump, and it needs to hold up on the coldest of those nights, not just the mild ones.
Any mini-split installed new has to meet the federal minimum for a split-system heat pump, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. That floor is the same everywhere, but here it matters more, since this unit earns its keep almost every month of the year.

Utah requires HVAC contractors to hold a state license.
The Division of Professional Licensing tests and keeps records on the contractor, not on each job they do. That license stays with the business across every installation they take on. Utah also carves out an exception. Work under $7,000 does not need a licensed contractor. A mini-split installation can land on either side of that line depending on the equipment and the job.
Most cities and counties require a permit for a job like this, with an inspection once the work is done. That inspection checks the installation itself, the wiring, the mounting, the way it was tied into the home. It is separate from whatever the state license covers.

- Is a mini split worth it?
- For most homes here, yes, especially if you're heating a room or addition that your main system doesn't reach well. Winters here get down to 13°F on average overnight, and a cold-climate mini split is built to keep producing heat at those temperatures, unlike older heat pump models. Summers only need cooling for July and August, so the same unit handles both jobs instead of running a separate window AC. A contractor can look at your specific rooms and tell you whether one unit covers the space or you need more than one.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, so the room count depends on which system you install. One indoor head handles one room or an open area well. If you want separate temperature control in multiple rooms, a multi-zone system puts a head in each room, all run from one outdoor compressor. A contractor can size the system to your rooms and tell you how many heads you need.
- Can a mini split heat a whole house?
- It can, but it takes the right number of indoor heads placed in the right rooms, not just one unit. A single head warms the room it's in and maybe an open space next to it, not the rooms down the hall. Whole-house coverage means a multi-zone system, with a head sized to each room and enough total capacity for the coldest nights, which here average 13°F. A contractor can size that out room by room for your house.
