Three months of heat, then it stops
Silver City only asks for cooling from June through August. Summer afternoons average 87°F, so a new air conditioner here has three months of real work each year, then sits idle the rest of the time.
What the outdoor unit sits through in those months matters too. Grant County has recorded 46 damaging wind events and 16 hail events over the past ten years, with hail up to 2 inches across. A new system should go in with that in mind, not just sized for the heat. Any central air conditioner built since 2023 has to meet a federal minimum of 14.3 SEER2, so that part is already decided for you.

New Mexico requires HVAC contractors to hold a state license.
New Mexico licenses HVAC contractors through the Construction Industries Division, and that license covers the contractor rather than the single job in front of them. It stays tied to them across whatever work they take on, not issued fresh for this installation.
For this job, the license is what stands behind the contractor doing the work. Installing an air conditioner also needs a permit from the local building office, and an inspection once the work is done, in most cities and counties. That inspection is what checks the installation itself, separate from the license that lets the contractor take the job on.

- What size air conditioner does my house need?
- The right size depends on your square footage, your ceiling height, how much shade your walls and windows get, and how well the house is insulated and sealed. A contractor works this out with a load calculation rather than a rule of thumb based on square footage alone. Going too big is as much a problem as going too small, since an oversized unit cools the air fast but shuts off before it pulls the moisture out, leaving the house feeling damp.
- Should I replace the whole system or just the outdoor unit?
- In most cases the outdoor unit and the indoor coil need to be matched, so replacing just one and keeping the other around can hurt efficiency and shorten the life of the new part. The age and condition of the indoor coil, and whether your ductwork can handle a new system's airflow, matter here too. A contractor can look at what you have and tell you whether the coil is worth keeping or whether the whole system should go in together.
- Do HVAC contractors in Silver City need a state license to work on my home?
- Yes. New Mexico requires HVAC contractors to hold a state license, issued through the Construction Industries Division, and that license covers the contractor rather than each individual job. Installing an air conditioner also typically needs a permit from the local building office, with an inspection once the work is finished.
