La Grande doesn't ask much of your AC, until a storm does

Summer afternoons here average 76°F, and most homes only need cooling for a short stretch of the year. That is easy work for an air conditioner, so when one does fail here, wear from long hours of running is usually not the reason.

What shows up in Union County is storm damage. The area has seen 22 hail events and 18 damaging wind events over the past ten years, with hail up to 1.75 inches recorded. Hail that size can dent or crack the thin aluminum fins on your outdoor unit, and high winds can rock the cabinet enough to loosen the refrigerant lines or knock it out of alignment. You will notice it as weak cooling, a unit that trips off, or a coil that looks bent or torn when you look at it.

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

  • A new one at the federal minimum, 13.4 SEER2$100 a year
  • An older air conditioner$110 a year

Estimates for a typical Union 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 repair itself, so the license on file tells you the business was tested and is on record with the state. In Oregon, work under $1,000 does not need a licensed contractor, so a small AC repair can fall outside that requirement depending on the bill.

Most air conditioner repairs involve opening the refrigerant side of the system, and federal rule requires anyone who does that to hold EPA Section 608 certification, no matter the size of the job or the state. That certification is separate from the state license and covers the technician handling refrigerant, not the business as a whole.

Why is my AC not blowing cold air?
The most common cause is low refrigerant from a leak somewhere in the coil or line set. A dirty air filter or a frozen evaporator coil will do the same thing, since blocked airflow stops the coil from pulling heat out of the air. Only a technician with EPA 608 certification can legally open the refrigerant side to check the charge and find a leak, so that part of the diagnosis has to be done in person.
Why is my AC leaking water?
Water around your unit usually means the condensate drain line is clogged. Algae and dust build up inside that line over time and eventually block it, so the water backs up and finds another way out. A frozen evaporator coil that later thaws can also flood the drain pan faster than it can drain. If the line looks clear and it still leaks, a cracked drain pan or a coil problem is worth having checked.
Why won't my AC turn on?
Start with the thermostat batteries and the breaker for the outdoor unit, since both are common and easy to rule out. If those check out, the problem is likely a failed capacitor or contactor, the parts that get the compressor and fan started. A contractor can test these parts directly rather than guessing which one gave out.
