Show Low asks a lot of your system, most of the year
Your furnace runs from October through May here, eight months of the year, and winter nights average 21°F from December through February. At that temperature the burner is cycling on and off for hours at a stretch, and every cycle puts wear on the igniter and the ignition control. When one of those parts finally gives out, the furnace stops firing on a night when you need it most.
Summer is shorter, just June through August, but afternoons average 88°F and the condenser has to work through it. That leaves only about a month a year when neither system is under real load. Show Low has also seen 137 winter storms and 162 damaging wind events over the past ten years, and outages follow. Most furnaces and water heaters come back on by themselves once power returns, but a system already worn down by the swings between 21°F and 88°F is more likely to fail right when the power does.

Arizona requires HVAC contractors to hold a state license.
Arizona licenses HVAC contractors through the Registrar of Contractors. That license covers the contractor, not each job, so the same license applies whether the work is a furnace repair or a heat pump repair.
For a repair to a heating and cooling system, that license is what stands behind the person doing the work. It belongs to the contractor, not to this particular job.

- Why is my heat not working?
- Start with the thermostat. Check that it's set to heat, not cool, and that the set temperature is above the room temperature. If that's fine, check the breaker for the furnace and, on a gas furnace, make sure the gas valve is open. A furnace that won't light at all often has a bad igniter or a flame sensor that needs cleaning, and either one needs a contractor to fix. At 21°F on a winter night here, a furnace that's short cycling or blowing cold air shouldn't wait.
- Why is my system running but not cooling the house?
- The blower may be moving air, but the air conditioner itself isn't cooling it. The most common cause is a dirty filter choking off airflow, so check that first and replace it if it's gray or clogged. If the filter is clean, the problem could be low refrigerant from a leak, a frozen evaporator coil, or the outdoor unit's fan or compressor not running. A contractor can tell you which one it is once they check the pressures and the outdoor unit.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it's set to the right mode and temperature, and replace the batteries if the screen is blank or dim. Next check the filter, since a clogged one can cause both heating and cooling problems, and swap it if it looks dirty. Then check the breaker panel for a tripped breaker, since power can go out after a storm and a tripped breaker won't reset on its own once it's back. If everything checks out and the system still isn't working, a licensed contractor can find out what's wrong.
