Teton County doesn't ask much of an air conditioner
Summer afternoons here average 69°F. That is mild enough that a new system spends most of the year barely working, if it runs at all.
The outdoor unit still has to sit through what this place does get. Twenty-one damaging wind events and four hail storms have hit the area over the past ten years, so it needs to be installed and positioned to take that on. Any unit built since 2023 has to meet a federal minimum of 13.4 SEER2, but with a cooling load this light, how well it is set up to handle wind and hail matters more than the rating on the label.

- What size air conditioner does my house need?
- The right size depends on your home's square footage, insulation, window placement, and layout, so a contractor needs to measure your house to answer this correctly. A unit that's too big cools the air fast but shuts off before it pulls the humidity out, leaving the house feeling damp. One that's too small runs constantly and still can't keep up on the hottest afternoons. This matters less here than in most places, since summer afternoons average only 69°F and cooling is rarely needed, but if you do want a system, a proper load calculation is still the only way to size it right.
- Should I replace the whole system or just the outdoor unit?
- If your indoor and outdoor units are more than a few years apart in age, replacing just the outdoor unit usually isn't a good idea. The two halves are matched to work together, and pairing an old indoor coil with a new outdoor unit can hurt efficiency and shorten the life of both. A contractor can check the age and condition of both pieces and tell you whether a full system replacement makes more sense than a partial one.
- Do HVAC contractors in Jackson need a state license to work on my home?
- Yes, HVAC work requires a state license. Ask to see it before any work starts, and confirm it's current. A licensed contractor has been tested on proper installation and safety practices, which protects you if something goes wrong with the work later.
