Oregon City doesn't ask much of an air conditioner

Summer afternoons here average 73°F. That's mild enough that an air conditioner in Clackamas County isn't running hard or running long, and it isn't fighting the kind of heat that wears a compressor down season after season.

When something does go wrong, it's rarely from heat stress. A hailstorm or a bad wind event can still damage the outdoor unit, bending the fins on the coil or knocking loose a wire, and that's when you'll notice the system short cycling, blowing warm air, or not starting at all.

A new air conditioner would save little on running costs in Clackamas County, so the repair decision comes down to the unit's condition.

  • A new one at the federal minimum, 13.4 SEER2$90 a year
  • An older air conditioner$100 a year

Estimates for a typical Clackamas County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Oregon fuel prices and NOAA climate normals. Your home will differ.

Repair makes sense when a part like a capacitor or contactor has failed.

Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.

Oregon requires HVAC contractors to hold a state license.

The Construction Contractors Board licenses the contractor, not the job. The state tests and records the business, and that license is what stands behind any air conditioner repair a licensed contractor takes on. Oregon does carve out an exception for work under $1,000, which does not need a licensed contractor at all.

Any technician who opens the refrigerant side of an air conditioner also needs EPA Section 608 certification, a federal requirement that applies no matter what state the work is in. On a repair like this one, that certification covers the part of the job a state license does not reach.

Why is my AC not blowing cold air?
The most common cause is low refrigerant from a leak somewhere in the line. A dirty air filter can also block airflow enough that the air coming out feels weak or warm. Sometimes the outdoor unit's coil is caked with dirt and can't release heat properly, so the system struggles to cool. Only a licensed contractor can check the refrigerant charge, since that means opening the sealed system, which requires EPA certification.
Why is my AC leaking water?
Usually the condensate drain line is clogged, and water backs up instead of draining outside. A dirty air filter can also cause this, because restricted airflow makes the evaporator coil freeze up, and the water shows up when it thaws. Less often, the drain pan itself has cracked or rusted through. Turning the system off until it's looked at keeps the water damage from spreading.
Why won't my AC turn on?
Start with the thermostat. Check that it's set to cool and the temperature is actually below the room temperature, and replace the batteries if it uses them. If that's not it, a tripped breaker or a blown fuse at the outdoor unit is the next likely cause. Given how few hot days this area sees, a system that won't start after sitting unused for months may just need a contractor to check it over before the next warm stretch.
