Five months of 94 degree afternoons wear an AC down

From May through September your air conditioner is running most of the day trying to hold the house against a 94°F afternoon. That kind of stretch puts real hours on the compressor and the fan motor, the two parts doing the actual work of moving heat out of the house. When one of them is starting to fail, you notice the air coming from the vents isn't as cold as it used to be, or the unit runs and runs without the house catching up.

Luna County has also seen 8 hail events and 18 damaging wind events over the past ten years, with hail up to 1.75 inches. The outdoor unit sits outside through all of it, and a hard enough storm can bend the thin fins on the coil or damage the fan. If your AC started acting up right after a storm, that is worth mentioning when it gets looked at.

A new air conditioner would cut about $60 a year off cooling for a typical Luna County home.

  • A new one at the federal minimum, 14.3 SEER2$410 a year
  • An older air conditioner$470 a year

Estimates for a typical Luna County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, New Mexico 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.

New Mexico requires HVAC contractors to hold a state license.

The Construction Industries Division is the state office that issues the license, and it covers the contractor, not the repair itself. That means the same license follows the contractor from job to job rather than being tied to your air conditioner specifically.

For a repair like this, that license is what stands behind the person working in your home. Because the job means opening the refrigerant side of the system, whoever does the work also needs EPA Section 608 certification, a federal requirement that applies in every state on top of New Mexico's own license.

Why is my AC not blowing cold air?
The most common reason is a dirty air filter or a coil that has iced over from restricted airflow. When that happens the system runs but the air coming out feels weak or warm instead of cold. Low refrigerant from a leak causes the same thing, and that's not something to check yourself since it means opening the sealed refrigerant side of the system. A contractor can tell within a few minutes whether it's airflow, ice on the coil, or refrigerant.
Why is my AC leaking water?
Most of the time it's a clogged condensate drain line. Your AC pulls moisture out of the air all day during a Deming summer, and that water has to drain out through a small line that algae and dust can block over time. Once it's blocked, the water backs up and drips or pools near the indoor unit. A frozen coil that's thawing out can cause the same kind of leak, so it's worth having someone look at both the drain and the coil.
Why won't my AC turn on?
Start with the thermostat batteries and the breaker before assuming the worst. If the breaker keeps tripping, that points to an electrical problem inside the unit and it shouldn't be reset over and over. A capacitor that's gone bad is another common reason the outdoor unit won't start even though the thermostat calls for cooling. Any of these needs a licensed contractor to open the unit and test it, and in New Mexico that contractor has to hold a state license through the Construction Industries Division.
