Los Lunas asks a lot of a heating and cooling system
Winter nights here average 23°F from December through February, and your furnace has to answer that from October through April, seven months a year. Summer afternoons average 91°F, and the air conditioner takes over for four more months, June through September. Only one month is left where the system can rest.
Most homes here heat with gas, and a new furnace has to be sized to hold the house steady on a 23°F night, not just take the edge off. A new air conditioner has to keep up on a 91°F afternoon without running flat out all summer. Valencia County has also seen 59 winter storms and 107 damaging wind events over the past ten years, and 13% of New Mexico households lost power for a day or more in 2024. Whatever gets installed should be able to come back on its own once the power does.

New Mexico requires HVAC contractors to hold a state license.
The license comes from the state's Construction Industries Division, and it covers the contractor, not the job. That means the state tested this contractor before handing out the license, and there's a record of who holds one. It doesn't mean a state inspector is coming to look at your new furnace or heat pump when it goes in.
That part comes from your local building office. Installing a heating and cooling system in most cities and counties in New Mexico needs a permit, and the finished work gets an inspection before anyone signs off on it. The license tells you the contractor was vetted. The permit and inspection tell you this particular installation was checked.

- When should I replace my HVAC system?
- Replace it once repairs start coming often, or once it can no longer keep the house comfortable through the winter lows and summer highs here. A furnace that struggles when nights drop to 23°F or an air conditioner that cannot keep up at 91°F is telling you something. If a technician has already been out more than once this year, that is usually a sign the system is closer to the end than the middle.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes. A furnace and air conditioner installed years apart often were not matched to work together, and replacing just one can mean the new part is held back by the old one. Homes here need heat seven months a year and cooling four, so both units get real use. If only one has failed and the other is still young, a contractor can tell you whether it makes sense to wait or replace both now.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner or heat pump and sets the new equipment in its place, then connects it to the ducts, the gas or electrical supply, and the thermostat. Refrigerant lines get connected and tested, and the system gets checked for proper airflow before the job is called done. In most cities and counties here, this work needs a permit from the local building office along with an inspection once it is finished. New Mexico also requires the contractor doing the work to hold a state license through the Construction Industries Division.
