Oregon City doesn't ask much of an air conditioner
Summer afternoons here average 73°F, mild enough that a new air conditioner isn't working against much. Any unit installed new still has to meet the federal minimum of 13.4 SEER2, so that part is settled before you even choose a model.
What matters here is getting the size right for a house that doesn't lean on cooling the way a hotter place would.
- 73°F
- the average summer afternoon it cools against
- 3 hail events
- in ten years, and hail bends the fins on outdoor coils
- 13.4 SEER2
- the federal minimum any new unit must meet

Oregon requires HVAC contractors to hold a state license.
The state license is held by the contractor, not issued job by job, so it follows the business across every install it does. Oregon's Construction Contractors Board records who holds one, which means a contractor's license history is on file with the state. Work under $1,000 falls outside that requirement, but installing an air conditioner runs well past that threshold, so the contractor doing this job needs to hold the license.
That license covers who is allowed to do the work. It does not replace the local permit and inspection this job still needs. In most cities and counties in Oregon, installing an air conditioner requires a permit from the local building office, and the finished work gets an inspection before it is signed off. The license says the contractor is accountable to the state. The permit and inspection say the installation itself gets checked once it is in your home.

- What size air conditioner does my house need?
- The right size depends on your square footage, how much sun your walls and windows get, your insulation, and your layout, so it takes a load calculation to get a real number. Oregon City summers stay mild, with afternoons averaging around 73°F, so a system sized for a much hotter climate would be more than your house needs. A contractor can walk through your home and run the numbers rather than guessing off square footage alone.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit were installed together and matched for each other, replacing only the outdoor unit can throw off that match and hurt efficiency. An old coil paired with a new condenser also tends to fail sooner, since the two were sized to work as a pair. A contractor can check the age and condition of the indoor coil and tell you whether it can run with a new outdoor unit or whether both need to go at once.
- Do HVAC contractors in Oregon City 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. The license applies to the contractor, not to each individual job. Installing an air conditioner is well above the small-job threshold where an unlicensed contractor is allowed to work, so this job calls for a licensed one. You will also need a permit from the local building office, with an inspection once the work is done.
