Los Alamos doesn't ask much of an air conditioner
Summer afternoons here average 80°F, mild enough that most homes get by without much cooling at all. An air conditioner in Los Alamos County isn't fighting the kind of heat that wears a system down through the summer.
What it does face is weather. The county has logged 10 hail events and 11 damaging wind events over the past ten years, with hail up to 1.25 inches. That's enough to dent a condenser's fins or bend the cabinet around it, and a unit that's been through a storm like that can start losing efficiency or making noise even if it still runs.

A new air conditioner would save little on running costs in Los Alamos County, so the repair decision comes down to the unit's condition.
Estimates for a typical Los Alamos 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 agency that issues the license and keeps the record of who holds one. That record follows the contractor, not the specific repair, so it does not reset or renew with each job someone takes on.
For a repair like this, the license is the thing accountable for the work in New Mexico. If the repair involves opening the refrigerant side of the system, which most air conditioner repairs do, the technician also needs EPA Section 608 certification, a federal requirement that applies in every state on top of whatever the state itself requires.

- Why is my AC not blowing cold air?
- The most common cause is low refrigerant from a leak, a dirty filter choking airflow, or a failing capacitor that won't let the compressor start. If the air coming out is warm or barely moving, check the filter first since that's the one thing you can look at yourself. Anything involving refrigerant needs a technician with EPA 608 certification, since that's federal law for opening the sealed system.
- Why is my AC leaking water?
- Water around your AC usually means the condensate drain line is clogged or the drain pan has rusted through. Algae and dirt build up in that line over time and block the water from draining outside like it should, so it backs up and drips near the indoor unit instead. A dirty filter can also cause the coil to ice over, and when that ice melts it can overwhelm the drain. This is worth having looked at soon, since water can damage the floor or ceiling around the unit.
- Why won't my AC turn on?
- Start with the thermostat and the breaker. If the thermostat display is blank, check the batteries first, then check whether the breaker for the outdoor unit has tripped. If power is fine and it still won't start, the problem is likely inside the unit, a bad capacitor, a failed contactor, or a tripped safety switch, and that calls for a licensed contractor to diagnose.
