Portales runs its system almost year round
Heat runs October through April here. Cooling picks up in May and carries through September. That is 12 months of work, with almost no season off.
Winter nights average 26°F, cold enough that a furnace cycles on and off most of the night to hold the house steady. Summer afternoons average 91°F, and an air conditioner runs long stretches to keep up. Most homes here heat with electricity, so when the grid goes down, the heat goes with it. Roosevelt County has seen 53 damaging wind events and 6 winter storms over the past ten years, and across New Mexico, 13% of households lost power for a full day or more in 2024. A system that loses power and does not restart on its own leaves a house cold on the coldest nights.

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, not to any single job, so the state has tested and recorded this person before they take on any work.
For a repair on a heating and cooling system, that license is what stands behind whoever does the work. Gas connections are the dangerous part of a repair like this, and the state license is what puts a name and a record behind the person making them.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat and set above the room temperature, since a setting bumped a degree or two can look like a dead system. If that is not it, check the breaker for the furnace and, if you have a gas furnace, make sure the switch on the unit or nearby wall is on. Winter nights here can drop to 26°F, so a furnace that will not fire is not something to sit on. If power and settings check out and you still get no heat, the igniter or a safety switch inside the furnace may be at fault, and that calls for a contractor licensed by the state to open it up.
- Why is my system running but not cooling the house?
- The most common reason is a dirty filter choking off airflow, so check that first. A blocked filter starves the coil of air, and the coil can ice over, which means the air coming out feels weak or barely cool at all. Look at the outdoor unit too. If the fan is not spinning or the coil is caked with dirt or grass clippings, it cannot shed the heat it is pulling from inside, and on a 91°F afternoon that shows up fast. If the filter is clean and the outdoor unit looks clear but the house still is not cooling, the refrigerant charge or a failing component inside the system is likely the issue, and that is a job for a licensed contractor.
- What can I check before calling for HVAC repair?
- Check the filter first. A filter clogged with dust will choke airflow and can make a furnace or air conditioner act like it is failing when it just cannot breathe. Check the thermostat batteries and its setting, and check the breaker box for anything tripped. If the outdoor unit is not running, look for anything blocking it, like leaves or debris around the base. None of this replaces a real diagnosis, but it rules out the simple causes before a contractor licensed by the state comes to look at the system itself.
