Roseburg doesn't ask much of an air conditioner

Summer afternoons here average 77°F. That's mild, and it means a new air conditioner in Roseburg isn't fighting the kind of heat that pushes a system hard, day after day. Any unit sized right for your house will keep up without much strain.

Any central air conditioner installed new has to meet a federal minimum of 13.4 SEER2. That's the baseline for efficiency no matter who installs it. Beyond that, what matters most here is a system sized correctly for your home, since you won't be leaning on it to fight extreme heat.

Oregon requires HVAC contractors to hold a state license.

The license comes from the Construction Contractors Board, and it belongs to the contractor, not to any single job. Work under $1,000 is the one carve-out, no license needed for a job that small, but installing an air conditioner runs well past that line.

For a job this size, the license is what stands behind the work. On top of that, most cities and counties here require a permit for an air conditioner installation, and an inspection once the work is done, so someone besides the contractor is checking the finished job.

What size air conditioner does my house need?
The right size comes from a load calculation, not the square footage of your house. A contractor looks at your insulation, your windows, how many walls face the sun, and your attic before landing on a number. Going too big is just as bad as going too small. An oversized unit cools the air fast then shuts off before it pulls the moisture out, so the house feels clammy even at the right temperature.
Should I replace the whole system or just the outdoor unit?
If the indoor coil and outdoor unit were installed together and matched, replacing only the outdoor unit can work. But if the indoor coil is old, a new outdoor unit paired with it often will not perform the way the rating on the box promises, and some manufacturers will not warranty the mismatch. A contractor can check the age and condition of both pieces and tell you whether they still pair well or whether it makes more sense to do both at once.
Do HVAC contractors in Roseburg 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, and installing an air conditioner is licensed work. The license covers the contractor, not the individual job, so it is worth asking to see it. Most cities and counties also require a permit and an inspection once the work is done, so ask that the contractor pull one.
