Two months of real heat, then it stops

Thermopolis only asks an air conditioner to work in July and August. Summer afternoons average 80°F, which is warm but not brutal, so the unit you install doesn't need to be sized for extreme heat that never comes.

Hail is the bigger risk to plan around. The county has logged 14 hail events and 68 damaging wind events over the past ten years, with hail up to 2.25 inches recorded. That means the outdoor unit's coil and fan housing take some risk sitting outside, and where you place it and how it's protected matters more here than the cooling load does. Any new central air conditioner installed today also has to meet the federal minimum of 13.4 SEER2.

What size air conditioner does my house need?
The right size depends on your home's square footage, insulation, window placement, and layout, not on a rule of thumb. An undersized unit will run constantly and never quite cool the house. An oversized one will cool fast, shut off, and leave the place clammy because it never runs long enough to pull moisture out of the air. A contractor will run a load calculation on your actual house to get this right.
Should I replace the whole system or just the outdoor unit?
If your indoor and outdoor units are original to each other and one is failing, replacing just the outdoor unit usually causes problems. The compressor is matched to the indoor coil and the blower, and pairing an old coil with a new condenser can hurt efficiency and shorten the life of the new part. Age matters too. A contractor can look at both units and tell you whether a matched pair makes sense for your situation.
Do HVAC contractors in Thermopolis need a state license to work on my home?
Licensing rules for HVAC contractors vary by state, so check with a contractor directly about what applies here. Ask about their experience with central air systems, whether they pull permits when required, and whether they carry insurance. A contractor who stands behind the work and is straightforward about what your system needs is worth more than a license number.
