Eleven months of work, most homes on electric heat
Nogales asks for heat November through April and cooling May through September. That is eleven months where the system is on, one after another with barely a break between them.
Winter nights average 33°F, cold enough that the furnace cycles on and off most of the night. Summer afternoons reach 90°F, and the AC runs long stretches to hold the house steady. Most homes here heat with electricity, so a power interruption means no heat at all, and Arizona households saw real outages last year, 7% of them out for 24 hours or more. The area has logged 17 winter storms and 53 damaging wind events over the past ten years, the kind of weather that knocks out power and puts a system through its two hardest jobs back to back.

Arizona requires HVAC contractors to hold a state license.
That license means the state tested this contractor before letting them work under that number, and the Registrar of Contractors keeps a record of who holds it. It covers the contractor as a whole, not the specific repair on your system, so the same license applies whether the job is a furnace or an air conditioner.
For a repair like this, that license is what stands behind the person in your house. Whoever is doing the work should be able to give you that license number, and it should belong to the business you hired, not just the person standing at your door.

- Why is my heat not working?
- The most common cause is the igniter or a flame sensor that has gone bad, especially if the furnace tries to start and then shuts off. A tripped breaker or a thermostat set wrong or out of batteries can also do it, so check those first. If the furnace is not even attempting to fire, and the filter is clean, it is worth having a contractor look at the igniter and the flame sensor. With most winter nights near 33°F here, this is not a repair to put off.
- Why is my system running but not cooling the house?
- If the outdoor unit and the fan are both running but the air coming out of the vents is not cold, check the filter first. A clogged filter starves the coil of airflow and it can ice over, which stops it from cooling even though the system sounds fine. If the filter is clean, the next likely cause is low refrigerant from a leak, and that needs a licensed contractor to find and fix. Running it low on refrigerant for long can damage the compressor, so do not wait once you notice it.
- What can I check before calling for HVAC repair?
- Start with the filter. A dirty filter is behind a lot of the calls that turn out not to need a repair at all. Check the thermostat next, the batteries and the setting, and check the breaker box for anything tripped. If the outdoor unit is not running, make sure nothing is blocking it and that the disconnect switch nearby is pushed in. Past that, if the system still is not heating or cooling right, it is time for a licensed contractor to look at it. Arizona requires an HVAC contractor to hold a state license through the Registrar of Contractors, so ask for that before any work starts.
