Eight months of heat, three of cooling, and not much room to rest
Your furnace runs from October through May here. On winter nights that average 20°F, it cycles on and off for hours, and every start puts wear on the igniter and the parts that get the burner lit. When one of those finally gives out, the furnace stops firing and the house goes cold fast at that temperature.
Summer is shorter but the afternoons average 85°F, so the AC still has real work to do for three months straight. Between the two seasons this system runs most of the year, and Apache County sees its share of winter storms and high wind. When the power drops, most furnaces and AC units come back on by themselves, but a system that was already weak going in is more likely to be the one that does not.

Arizona requires HVAC contractors to hold a state license.
The Registrar of Contractors is the state body that issues this license, and it covers the contractor rather than the specific job. That means the license belongs to the business itself, not to any one repair, and it stays with them from job to job rather than being granted fresh each time.
For a repair to your heating and cooling system, that license is what stands behind the person doing the work. It is not a sign-off on this particular repair, since Arizona ties the license to the contractor and not the job.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat and set a few degrees above room temperature, and check that it has power if it uses batteries. If the thermostat looks right, check the breaker for the furnace and the switch that looks like a light switch near the unit, since that shuts it off for service and gets left off by accident. A furnace that hits 20°F nights all winter runs hard here, and if the flame won't stay lit or the blower never kicks on, that points to something a contractor needs to look at, like the igniter or a safety switch.
- 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 when that happens the coil can ice over and blow warm air even though the system is running. Check the outdoor unit too, and clear away leaves, grass clippings or anything sitting against it, since it needs open airflow to move heat outside. If the filter is clean and the outdoor unit is clear and the house still is not cooling on an 85°F afternoon, the system needs a contractor to check the refrigerant charge or the coil itself.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in it, and the breaker for the unit. These cause more no-heat and no-cool calls than an actual broken part, and ruling them out first saves time. Check the air filter and replace it if it is gray or clogged, since a blocked filter can look like a bigger problem than it is. If everything there checks out and the system still is not heating or cooling, a licensed contractor can diagnose what a filter and breaker check can't catch.
