Delta asks a mini-split to work almost all year
A mini-split here heats from October through May and cools June through August, 11 months of the year with barely a break between. Winter nights average 20°F from December through February, and the unit has to hold that ground for the whole stretch. Come summer, afternoons average 89°F and it switches straight to cooling.
A new ductless system installed today has to meet the federal minimum for split-system heat pumps, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. There is no separate ductless standard. With this much of the year spent heating or cooling, that rating is the baseline the equipment needs just to keep up with what Delta asks of it.

Utah requires HVAC contractors to hold a state license.
The Division of Professional Licensing issues the license and keeps the record on file, but it licenses the contractor, not each job. In Utah, work under $7,000 does not need a licensed contractor at all, so whether that license applies to your mini-split depends on where the total for this installation lands.
If the job falls under that threshold, the protection comes from somewhere else. In most cities and counties, installing a mini-split needs a permit from the local building office and an inspection once the work is done. That inspection is what catches a bad connection or a system put in wrong, not a license number.

- Is a mini split worth it?
- For most homes it comes down to what you're heating or cooling and how the space is set up now. A mini split heats and cools without ducts, so it works well for additions, garages, or a house that relies on baseboard or window units. Winters here get down to 20°F on average, and a mini split rated for cold climates can still deliver heat at those temperatures, so it can serve as your main heat source or back up a furnace on the coldest nights. A contractor can look at your home and tell you whether it makes sense over what you have now.
- How many rooms can a mini split cover?
- A single indoor head heats and cools the one room or open area it's mounted in. If you need coverage in several rooms, a multi-zone system runs more than one indoor head off a single outdoor unit, and some outdoor units support up to eight zones. How many rooms one system can actually handle depends on the size of each room and how the walls and doors break up the space, so a contractor will need to see the house to size it right.
- Can a mini split heat a whole house?
- It can, but it takes the right number of zones placed where the heat needs to go. A ducted furnace pushes warm air through vents into every room automatically. A mini split only heats the rooms with an indoor head, so covering a whole house means a head in each main room or zone, not just one unit in the living room. With winter lows averaging 20°F here, a system built for whole house heating needs to be sized for that cold, and a contractor can work out how many zones your house needs.
