Laramie doesn't ask much of an air conditioner

Summer afternoons here average 76°F. That is mild enough that most homes get by without cooling at all, so a system installed here spends most of its life sitting idle rather than working.

What it does have to survive is the weather. Albany County has logged 47 hail events and 2,974 damaging wind events over the past ten years, with hail up to 3 inches recorded. That is what an outdoor unit here has to hold up against, whether it runs much or not. Any new central air conditioner installed today also has to meet the federal efficiency minimum of 13.4 SEER2.

What size air conditioner does my house need?
The right size depends on your square footage, your insulation, how many windows you have and which way they face, and the height of your ceilings. A contractor works this out with a load calculation, not by matching the size of your old unit or guessing from square footage alone. An oversized system cools the air fast but shuts off before it pulls the moisture out, so the house feels clammy. An undersized one runs constantly and never quite catches up on the hottest afternoons. Summer afternoons in Laramie average 76°F, so the load on a house here tends to be lighter than in a hotter climate, which is one more reason to have someone calculate it rather than assume.
Should I replace the whole system or just the outdoor unit?
If your indoor coil and outdoor unit are matched and both in good shape, replacing just the outdoor unit can work. A mismatched coil and condenser can run poorly and wear out sooner. Refrigerant type matters too, since older units may use a refrigerant that new equipment isn't built for. A contractor can look at the age and condition of both pieces and tell you whether pairing a new outdoor unit with your existing coil makes sense for your setup.
Do HVAC contractors in Laramie need a state license to work on my home?
Ask any contractor for proof of licensing, insurance, and a record of past work before they start. Electrical or gas work connected to an installation often calls for separate licensed trades, so it is worth asking who is covering each part of the job. A reputable contractor will have no trouble showing you their credentials.
