Rawlins doesn't ask much of an air conditioner

Summer afternoons here average 78°F. That's mild, and a new air conditioner in Rawlins isn't fighting the kind of heat that pushes a system hard, day after day. Sized right for the house, it keeps up without much strain.

Hail and wind are the bigger concern. The area has seen 13 hail events and 1,556 damaging wind events over the past ten years, and a condenser sits outside, exposed to both. Whoever installs it should place and protect it with that in mind. If you're installing new, the unit also has to meet the federal minimum of 13.4 SEER2, the efficiency rating that applies to central air conditioners built since 2023.

  • A higher-efficiency unit$60 a year

What size air conditioner does my house need?
The right size depends on your square footage, your windows, your insulation and how much shade your house gets, so there is no single number that fits every home. A contractor works this out with a load calculation, not a chart based on house size alone. Going bigger than what the calculation shows is not better. An oversized unit cools the air fast and shuts off before it pulls the moisture out, so the house feels clammy even at the right temperature.
Should I replace the whole system or just the outdoor unit?
If the indoor coil and outdoor unit were installed together and matched for each other, replacing just the outdoor unit can throw that match off, and the system ends up working harder for less cooling. Age matters too. If the indoor coil is old, it may not hold up well paired with a new outdoor unit, and you could be back to replacing it again soon after. A contractor can check the age and condition of both halves and tell you whether a matched pair makes more sense here.
Do HVAC contractors in Rawlins need a state license to work on my home?
Ask to see a contractor's license before any work starts, and confirm it is current. A licensed contractor also carries the insurance that protects you if something goes wrong during the installation. If you are not sure a license is valid, the state licensing board can confirm it for you.
