Riverton doesn't ask much of an air conditioner

Summer afternoons here average 77°F, so a new system in Riverton isn't fighting extreme heat. The work is sizing it right for a mild climate, not chasing extra capacity you won't use.

The bigger concern is what sits outside all year. Fremont County has logged 30 hail events and 342 damaging wind events over the past ten years, and the outdoor condenser takes that weather directly. The cabinet and fins matter as much as the cooling power. Any new system installed now has to meet the federal minimum of 13.4 SEER2.

What size air conditioner does my house need?
The right size comes from a load calculation, not the square footage of your house. A contractor looks at your windows, insulation, ceiling height, and how much sun your walls get before landing on a number. An oversized unit cools the air fast but shuts off before it pulls the moisture out, so the house feels clammy. Given that Riverton summers average 77°F in the afternoon, the calculation for a lot of homes here comes back smaller than people expect.
Should I replace the whole system or just the outdoor unit?
If your indoor coil and outdoor unit were matched when installed, replacing only the outdoor unit can throw that match off and hurt efficiency. Refrigerant and coil designs change between generations, so a new outdoor unit paired with an old indoor coil sometimes will not run the way it should. A contractor can check whether your existing coil and line set are compatible with the new unit. If the indoor coil is old or was not sized for a new unit, replacing both is usually the safer call.
Do HVAC contractors in Riverton need a state license to work on my home?
Yes, HVAC contractors need a state license to install or repair central air conditioning systems. Licensing means the contractor has passed the trade knowledge and safety requirements the state sets. It also gives you recourse if the work does not hold up. Ask to see the license number before signing anything.
