Greeley asks a mini-split to run most of the year
Winter nights here average 16°F from December through February, and a mini-split has to keep pulling heat from air that cold. Summer afternoons average 86°F, so the same unit switches over and works the other direction a few months later. Homes here need heat or cooling 11 months a year, with heat running October through May and cooling June through August.
A new mini-split sold today has to meet the federal minimum for split-system heat pumps, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. Colorado has recorded 42 winter storms and 172 damaging wind events over the past ten years, and 13% of households in the state went at least 24 hours without power in 2024. Worth asking how the unit you install handles a cold snap if the power drops with it.

- Is a mini split worth it?
- For most homes here, yes, especially if you're heating or cooling a room your furnace or central air doesn't reach well. A mini split runs on a heat pump, so it can both heat and cool from the same unit, which matters here since homes need one or the other 11 months of the year. Winter nights average 16°F, and modern cold-climate mini splits are built to keep producing heat at those temperatures, so it holds up through a Greeley winter. Whether it's worth it for your house depends on what you're trying to heat or cool and what's there now, so a contractor should look at the space before you decide.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, depending on the system. Single-zone systems cover one room or open area. Multi-zone systems connect up to eight indoor heads to one outdoor unit, each with its own thermostat, so you can heat or cool several rooms independently. How many rooms makes sense for your house depends on the layout and how those rooms are used, which a contractor can size once they see the space.
- Can a mini split heat a whole house?
- It can, but it takes the right number of indoor units placed where the house actually loses heat, not just one head in the living room. A multi-zone mini split can cover a whole house the way a furnace does, and it also cools in summer, which a furnace can't. Given that winter nights here average 16°F, the system needs to be sized for that low end, not just for a mild day. A contractor can work out how many zones your house needs to actually heat every room, not just the one the unit sits in.
