Eleven months of work, most of it in the cold
Farmington only gets a break from the furnace in June and August, with the same easy stretch in between. The other eight months, it's running against nights that average 20°F from December through February. Gas fires 63% of the furnaces here, and every cold start puts wear on the igniter and the burner. When one finally fails, it fails on one of those cold nights.
Summer asks less of the system but doesn't let it rest either. Afternoons average 88°F for three months, and the AC has to keep up right after the furnace finishes an eight month run. San Juan County has seen 30 winter storms and 42 damaging wind events over the last ten years, and outages come with weather like that. Statewide, 13% of households went at least 24 hours without power in 2024. A furnace with a standing pilot will relight on its own, but most modern ones wait for the power to come back before they'll run again.

A new furnace and air conditioner would cut about $100 a year off heating and cooling for a typical San Juan County home.
Estimates for a typical San Juan 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.
New Mexico licenses HVAC contractors through the Construction Industries Division. That license belongs to the contractor, tested and on record with the state, not to any single job. It covers the business doing the work, not this particular repair.
For a repair on a heating and cooling system, that license is what stands behind the person working in your home. The state has tested them and keeps a record of who they are. In New Mexico, this is the credential to look for, since the license covers the contractor and not each job separately.

- Why is my heat not working?
- Start with the thermostat. Check that it is set to heat, the set temperature is above room temperature, and the display is lit. If the thermostat looks fine, check your breaker panel and any switch near the furnace that looks like a light switch, since that shuts the whole unit off if it gets bumped or turned off during other work. Gas furnaces also need a pilot light or an igniter to spark, and if that fails the burners never light even though the blower may still run. At 20°F on a winter night here, a furnace that won't light needs a contractor licensed by the Construction Industries Division to find out why.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the coil, and without enough airflow the coil can ice over and stop cooling the air at all. Next check the outdoor unit and clear away any leaves, grass clippings, or debris sitting against it, since it needs open air around it to release heat. If the filter is clean and the outdoor unit is clear, the system may be low on refrigerant or have a failing part, and that takes a licensed contractor to diagnose. On an 88°F afternoon a system that's losing the fight against the heat should get looked at before it stops cooling entirely.
- What can I check before calling for HVAC repair?
- Check the thermostat settings and its batteries if it takes any. Check the breaker panel for a tripped breaker and any power switch near the indoor or outdoor unit. Check the air filter and replace it if it's dirty, since restricted airflow causes problems with both heating and cooling. If the outdoor unit is covered in debris, clear the area around it. These checks take a few minutes and rule out the simplest causes, but anything beyond them, a gas valve, an electrical part, a refrigerant leak, needs a licensed contractor to open the system safely.
