Roswell asks a mini-split to run all year
Your mini-split heats the house from October through April, then cools it from May through September. That is 12 months a year with no real break. Winter nights average 27°F. Summer afternoons average 93°F. The compressor rarely gets to sit idle for long.
More than half the homes here heat with electricity, so a heat pump carries more of that load than it would where gas does part of the work. 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 is the floor for a unit built after January 1, 2023, not a target to aim for.

New Mexico requires HVAC contractors to hold a state license.
The Construction Industries Division licenses the contractor as a business, not the job itself. That license covers who is allowed to do HVAC work in New Mexico. It does not cover what happens once they are in your house.
A mini-split install in most New Mexico cities and counties 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 it happens here, at the address, after the unit is mounted and running. It checks how the job itself was done, not who was allowed to do it.

- Is a mini split worth it?
- For most homes here, yes. It heats and cools without ductwork, and this climate needs both, with winter nights averaging 27°F and summer afternoons averaging 93°F. It runs as a heat pump, so the same system covers heating from October through April and cooling from May through September. Whether it makes sense for your house depends on what's there now and which rooms need coverage, and a contractor can walk through that with you.
- How many rooms can a mini split cover?
- A single outdoor unit can run more than one indoor unit, called a head, with each head placed in a separate room or open area. The outdoor unit has to be sized for the combined load of every head connected to it, not just one room. A contractor can tell you how many heads your house needs and whether one outdoor unit covers all of them or you need more than one.
- Can a mini split heat a whole house?
- It can, if there are enough indoor heads placed to reach every room and the outdoor unit is sized for the whole house rather than part of it. That matters here since homes need heat from October through April, seven months a year, with winter nights averaging 27°F. A mini split installed to cover one or two rooms will not heat the rest of the house, so whole-house coverage has to be planned that way from the start.
