Astoria doesn't ask much of an air conditioner
Summer afternoons here average 70°F. That's mild enough that a lot of homes in Clatsop County get by without cooling at all, and the ones that install it aren't fighting the kind of heat that pushes a system hard.
If you're installing new, any central air conditioner put in since 2023 has to meet a federal minimum of 13.4 SEER2. In a climate this mild, you won't lean on it often, but it's worth sizing correctly for the home rather than oversized for a heat that rarely shows up.

Oregon requires HVAC contractors to hold a state license.
The Construction Contractors Board issues that license, and it belongs to the contractor rather than to any single job. It stays on file with the state before this job starts and after it ends. Oregon does carve out an exception for small jobs. Work under $1,000 does not need a licensed contractor. An air conditioner installation runs well past that line, so the contractor doing this job needs to hold the license.
Most cities and counties in Oregon require a permit from the local building office for this kind of installation, with an inspection once the work is finished. That inspection is what checks the installation itself, separate from whatever the state license already covers about the contractor.

- What size air conditioner does my house need?
- The right size depends on your square footage, your ceiling height, how many windows you have and which way they face, and how well insulated the house is. A contractor works this out with a load calculation, not a guess based on square footage alone. Getting this wrong in either direction costs you. Too small and it runs constantly without keeping up. Too big and it cools the air fast but shuts off before it pulls the moisture out, leaving the house feeling damp. Astoria summers rarely push past 70°F, so an oversized unit is the more common mistake here, since the system barely has to work to hit the thermostat setting.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are different ages or different efficiency levels, replacing only the outdoor unit can cause them to run poorly together. Some manufacturers will not warranty a mismatched pair. A contractor can check whether your existing coil and ductwork will work with a new outdoor unit or whether the mismatch will cause problems. Age matters too. If the indoor coil is old enough that it could fail soon after, pairing it with a new outdoor unit means paying for that labor twice.
- Do HVAC contractors in Astoria need a state license to work on my home?
- Yes. Oregon requires HVAC contractors to hold a state license, issued through the Construction Contractors Board. That license is tied to the contractor, not to any single job, so it is worth checking before work starts rather than assuming it. Installing an air conditioner is above the threshold where Oregon allows unlicensed work, and it also needs a permit from the local building office along with an inspection once the job is done. A contractor will price the job once they see the house.
