Polk County summers don't ask much of an air conditioner
Summer afternoons here average 77°F. That's mild, and it means a new air conditioner in Polk County isn't fighting the kind of heat that wears down a system fast.
Any new central air conditioner installed still has to meet the federal efficiency minimum of 13.4 SEER2. That's the baseline whether the summers are mild or brutal, so the unit going in should be sized right for the house, not oversized to handle heat that doesn't happen here.

Oregon requires HVAC contractors to hold a state license.
The Construction Contractors Board licenses the contractor, not each job. That license means the state has tested the contractor and keeps them on file. Work under $1,000 does not need a licensed contractor, but that is the exception, not the rule for a job like this one.
The license covers who is allowed to do the work. The permit covers this install. Most cities and counties in Oregon require a permit for an air conditioner replacement, along with an inspection once the work is done, and that inspection comes from the local building office, separate from the state license.

- What size air conditioner does my house need?
- The right size depends on your home's square footage, insulation, windows, and layout, not a rule of thumb based on the house next door. A contractor works this out with a load calculation, which looks at how much heat your house gains on the hottest days. A unit that's too big or too small wastes energy and wears out faster, so this step matters more than picking a brand.
- Should I replace the whole system or just the outdoor unit?
- If your indoor and outdoor units are close in age, replacing both usually makes more sense than swapping just one. An old indoor coil paired with a new outdoor unit often runs less efficiently and can shorten the life of the new equipment. A contractor can check whether your existing indoor coil is compatible with a new outdoor unit before you decide.
- Do HVAC contractors in Dallas need a state license to work on my home?
- Check that whoever installs your air conditioner is licensed before the work starts. Licensing covers the contractor, not each individual job, so it's worth confirming rather than assuming. Most cities also require a permit and inspection for a new AC installation, so ask whether that's part of the job.
