Two months of real heat, and that's about it
Emmett only asks a new air conditioner to work July and August. Summer afternoons average 85°F, which is warm but not brutal, so the system you install doesn't need to be oversized for some worst case that never comes. It needs to be sized right for a short, predictable season and left alone the rest of the year.
A new central air conditioner installed here has to meet 13.4 SEER2, the federal minimum since 2023. Wind is the bigger thing to plan around, not heat. Gem County has logged 12 damaging wind events over the past ten years, so how the outdoor unit is mounted and secured matters more than the size of the compressor inside it.

Idaho requires HVAC contractors to hold a state license.
Idaho's HVAC Board issues the license to the contractor, not to the job. It covers the person or business doing the work, not this specific installation.
For the air conditioner going into your home, that license is what stands behind the contractor. Most cities and counties in Idaho also require a permit from the local building office for an installation like this, along with an inspection once the work is done.

- What size air conditioner does my house need?
- The right size depends on your square footage, how much shade and sun the house gets, your insulation, and how many windows you have, so there's no single number that works for every home. A contractor sizes the unit with a load calculation that looks at all of that together. Going bigger than you need isn't a safety net either, an oversized unit cools the air fast but shuts off before it pulls the humidity out, so the house feels clammy even at the right temperature. With only July and August to worry about here, it's worth getting the size right rather than guessing high.
- Should I replace the whole system or just the outdoor unit?
- If your indoor and outdoor units are original to each other and roughly the same age, replacing just the outdoor unit usually isn't the better move. The two are matched to work together, and pairing a new outdoor unit with an old indoor coil can mean the system never reaches the efficiency either piece was built for. A contractor can check the age and condition of the indoor coil and tell you whether it's worth keeping or whether replacing both at once makes more sense. Since summers here only run two months, either way you have some room to plan the work before you need the system.
- Do HVAC contractors in Emmett 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, and that covers installing an air conditioner. You'll also need a permit from the local building office for the installation, with an inspection once the work is finished. Asking to see the license before work starts is a fair thing to do.
