AC installation cost by system.
Installed pricing for Los Alamos, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Los Alamos, NM, AC installation costs range from $3,700 to $7,500 for a like-for-like central AC replacement, and $5,600 to $12,200+ if new ductwork is needed. Ductless mini-splits run $2,800–$7,500, while heat pumps are $4,700–$11,200+. The typical home was built in 1974, so many systems are aging or use evaporative cooling. A common upgrade is converting from swamp coolers to refrigerated air, which requires a mechanical permit from the local AHJ. With a hot-dry climate and moderate cooling demand, a gas furnace paired with a high-efficiency AC is a recommended system choice.

What Los Alamos code requires
Installing or replacing an HVAC system in Los Alamos follows New Mexico rules under the state mechanical code. Here’s what applies statewide:
- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum14.3 SEER2 (Southwest, <45k BTU)
Federal Southwest-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Hot-dry climate means many homes run evaporative (swamp) coolers; swamp-cooler-to-refrigerated-air conversions are common and need a CID/local AHJ mechanical permit. Southwest region also carries an EER2 minimum on new ACs.
