Eleven months of work, most years
Your furnace and your AC both earn their keep here. Heat runs October through April, seven months, and on winter nights that average 27°F the burner cycles on and off most of the night to keep up. Summer afternoons push past 90°F and the AC takes over for four more months. Only one month off, if that.
All that cycling wears on the parts that start each run, the igniter and the capacitor especially. The county sees real weather too, 32 damaging wind events and 4 winter storms over the last ten years. Wind can loosen an outdoor unit's wiring or throw debris into it. Across New Mexico, 13% of households lost power for a day or more in 2024. Most systems restart on their own once power is back. If yours does not, that is worth a look before the next cold night or hot afternoon puts it to work again.

NOAA nClimDiv, 1991–2020 normals
A new furnace and air conditioner would cut about $90 a year off heating and cooling for a typical Sierra County home.
Estimates for a typical Sierra 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 one part has failed.
Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.
New Mexico requires HVAC contractors to hold a state license.
The Construction Industries Division tests and licenses HVAC contractors before they can take on this kind of work in New Mexico. That license belongs to the contractor, not to the specific job, so it covers who is allowed to do the work rather than a sign-off on each repair.
For a repair on a heating and cooling system in Sierra County, that state license is the thing accountable for the work. The contractor doing the repair is required to hold it.

- Why is my heat not working?
- Start with the thermostat. Check that it is set to heat and the temperature is set above room temperature, and check the batteries if it uses them. If the thermostat looks right, check the breaker for the furnace or air handler, since a tripped breaker will shut the whole system down. Gas furnaces also need the pilot light or igniter to work and the gas valve to be open, so if you smell gas or hear repeated clicking without ignition, turn the system off and call a contractor instead of troubleshooting further. Winter nights here average 27°F, so a furnace that will not start is worth getting looked at the same day.
- Why is my system running but not cooling the house?
- The most common cause is a dirty air filter blocking airflow, so check that first and replace it if it looks gray or clogged. Next check the outdoor unit and clear away any leaves, grass clippings or debris that could be blocking airflow around it. If the filter is clean and the outdoor unit is clear but the air coming from the vents is not cold, the system may be low on refrigerant or have a failing part, and that needs a contractor to diagnose. With summer afternoons here averaging 90°F, a system that runs without cooling can let a house heat up fast, so it is worth having checked soon.
- What can I check before calling for HVAC repair?
- Check the thermostat settings and batteries first, since a wrong setting or dead batteries can look like a bigger problem. Check the breaker box for a tripped breaker on the furnace, air handler or outdoor unit. Look at the air filter and replace it if it is dirty, since restricted airflow affects both heating and cooling. If the system still is not working after these checks, a licensed contractor will need to look at it, since New Mexico requires HVAC contractors to hold a state license for this kind of repair work.
