Three months of real heat, then it stops
Payette County asks for cooling from June through August, with summer afternoons averaging 88°F. That is a short season compared to a lot of the country, but a hot one while it lasts, and a new system needs to keep up on the afternoons that push past that average.
Any central air conditioner installed new has to meet a federal minimum of 13.4 SEER2. That is the floor, not a rating specific to your house, so it is worth asking what a contractor recommends beyond it for a system that will spend most of the year sitting idle and then run hard for a stretch each summer.

Idaho requires HVAC contractors to hold a state license.
The license is held by the contractor's business, not issued job by job, so the same license covers this installation and every other job that contractor takes on. The state's HVAC Board is the one testing and keeping record of who holds it.
For this job, that license is what stands behind the person doing the work. On top of it, an air conditioner installation in most cities and counties in Idaho needs a permit from the local building office, with an inspection once the work is finished.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not a chart based on square footage. A contractor measures your insulation, window area, ceiling height, and how much shade your house gets before recommending a ton size. An oversized unit cools the air fast but shuts off before it pulls the humidity out, so the house feels damp even when the thermostat says it's cool enough. With summer afternoons here averaging 88°F, getting that size right matters more than it would somewhere milder, since the unit has real work to do most days from June through August.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are matched and both still have years left in them, replacing just the outdoor unit can work. But mismatched systems lose efficiency and can shorten the life of the new part, since the coil and the compressor are engineered to run together. A contractor can check the age and condition of both pieces and tell you whether swapping one makes sense or whether you're better off doing both at once.
- Do HVAC contractors in Payette 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, before they can install or work on your air conditioner. You'll also likely need a permit from the local building office for an AC installation, with an inspection once the work is finished. Checking that a contractor is licensed before they start is worth doing, since it's tied to whether the permit and inspection go through cleanly.
