New Mexico Property Manager HVAC Laws: What Property Managers Need to Know
If you manage residential rental properties in Albuquerque, there’s a good chance you already stay on top of maintenance, tenant communication, and the dozens of other details that keep a property running smoothly. Now there’s a new item on the compliance checklist that’s worth a closer look: Albuquerque now requires landlords to have cooling systems up and running by May 1 — and the city is enforcing it.
Albuquerque’s New Cooling Ordinance
In April 2026, the Albuquerque City Council passed Ordinance O-26-22, amending the Uniform Housing Code to require landlords to operate cooling systems from May 1 through September 30.
The ordinance is pretty straightforward. Starting May 1 each year, every residential rental unit in Albuquerque must have a functioning cooling system, and it must stay operational through September 30.
Approved systems include evaporative coolers, central AC, heat pumps, radiant cooling, window units, and mini-splits. Fans and portable ACs don’t count, except as a temporary stopgap when a permanent system is being repaired or replaced.
Systems must also perform consistently with how they were designed to operate. That means a swamp cooler that’s technically running but not producing a meaningful temperature drop likely doesn’t meet the standard.
Note: An earlier version of the ordinance would have required systems to maintain indoor temperatures at or below 80°F at three feet above the floor. That specific temperature threshold was removed before final passage, but the requirement that systems perform as designed remains.
New Mexico State Law
The Albuquerque ordinance builds on an existing foundation. Under the New Mexico Uniform Owner-Resident Relations Act, landlords are already required to maintain all HVAC systems in good, safe working order as part of the implied warranty of habitability.
If a tenant submits a written repair request and you don’t respond within 7 days, they can legally withhold up to one-third of their prorated rent, or 100% if the unit is uninhabitable. The new Albuquerque ordinance makes enforcement easier and more specific.
