Step 1 of 3: Equipment
Kemmerer asks a mini-split to run almost all year
Heat is on from August through June here, eleven months of the year. That means a mini-split's compressor is working most months, not just through a short cold snap. Winter nights average 8°F. A mini-split installed here has to be sized for that kind of cold, not just mild spring and fall days.
Any new mini-split has to meet the federal minimum for split-system heat pumps. That means 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. Summer afternoons here average 75°F, so cooling is not what this system is built around. The heating side is what matters most, since that is what it will be doing nearly all year.

- Is a mini split worth it?
- It depends on what you're heating and for how long, but in Kemmerer that math leans in its favor. Winter nights here average 8°F, and homes need heat from August through June, so a mini split is running most of the year, not just a few cold snaps. A modern heat pump mini split works down to very low outdoor temperatures, and it heats and cools from the same unit. The real question is whether it's covering one room, a few rooms, or standing in for your main heat source, since that changes what size and how many heads you need.
- 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 well. Multi-zone systems tie two to eight indoor heads to one outdoor unit, with each head handling its own room and its own thermostat setting. The right number comes down to the size of each room and how much heat it loses, which is something a contractor works out room by room, not with a flat rule.
- Can a mini split heat a whole house?
- It can, if enough zones are installed to reach every room. A multi-zone system with heads placed through the house can serve as the main heat source, and modern heat pump models are built to keep working through real cold, which matters here since winter nights average 8°F. What it takes to cover your whole house depends on the layout, the room sizes, and how the house holds heat, so a contractor needs to look at the place before sizing the system.
