It takes about a minute.
Two months of real heat, then it's done
Rigby only asks a new air conditioner to work July and August. Summer afternoons average 83°F, which is not extreme, but the unit still needs to be sized right and installed right to earn its keep in that short stretch.
Jefferson County has also logged 144 damaging wind events and 8 hail events over the past ten years, with hail up to 1.25 inches. The outdoor unit sits outside through all of that. A new central air conditioner installed today has to meet a federal minimum of 13.4 SEER2, so efficiency is built in. What matters after that is a unit and installation that can take a hailstorm or a windstorm without missing next summer.

Idaho requires HVAC contractors to hold a state license.
Idaho tests contractors through the HVAC Board before they can hold a license, and that license stays with the contractor, not with any one job. It covers the person or business doing the work, not each installation they take on.
For this job, the license is what backs the contractor doing the install. Most cities and counties also require a permit for an air conditioner installation, and an inspection once the work is done. That inspection is separate from the license. It is someone from the local building office checking this specific job after it is finished.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not a rule of thumb based on square footage. A contractor looks at your home's insulation, window area, ceiling height, and layout to figure out how many BTUs of cooling you actually need. Too big and the unit will short cycle, cooling the air fast but leaving it damp. Too small and it will run constantly through July and August without keeping up. That calculation is worth having done for your specific house rather than guessed at.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit were matched when installed, replacing just the outdoor unit can throw off that match and hurt both efficiency and cooling. Mismatched systems also make it harder for a contractor to guarantee the performance of the new unit. Age matters too. A furnace or coil that's near the end of its life will likely fail soon after, so you'd be paying for labor twice. A contractor can look at what you have and tell you whether the parts on hand are worth keeping.
- Do HVAC contractors in Rigby need a state license to work on my home?
- Yes. Idaho requires HVAC contractors to hold a state license, issued by the state's HVAC Board. For an air conditioner installation, you'll also need a permit from the local building office, and the work gets inspected once it's done. Asking to see the license before work starts is reasonable, and a licensed contractor will expect the question.
