Prescott Valley asks a lot of a furnace
Your furnace runs from October through April here, seven months of the year. On nights that average 31°F, it cycles on and off for hours at a stretch to keep up. Every start puts a load on the igniter and the parts that get the burner lit, and that wear is what fails first.
About half the homes here heat with gas, so a lot of furnaces are doing this same work night after night all winter. Yavapai County has also seen 44 winter storms and 94 damaging wind events over the last ten years, and statewide, 7% of households lost power for a day or more in 2024. When the power drops on a cold night, the furnace stops with it, and most come back on their own once power returns. If yours does not, or if it is cycling more than it used to, that is worth having someone look at.

Repair makes sense when one part has failed and the heat exchanger is sound.
Replacement makes sense when the heat exchanger is cracked or the furnace keeps needing parts.
Arizona requires HVAC contractors to hold a state license.
The Registrar of Contractors tests contractors before they can hold a license, and keeps a record of who holds one. That license belongs to the contractor, not to any single job, so it does not need to be reissued for each furnace repair a contractor takes on.
For a gas furnace, the part that matters most is the gas connection itself, since a bad one is what makes the job dangerous. In Arizona, the license is what stands behind that work, because the state has already tested the contractor doing it. In Yavapai County, close to half of homes heat with gas, so this is a repair the Registrar's licensing was built to cover.

- Why won't my furnace turn on?
- Start with the thermostat. Check that it's set to heat and the temperature is above room temperature, and check the batteries if it uses them. If the thermostat looks fine, check the breaker box, since a tripped breaker will shut the whole system down. Furnaces also won't run if the air filter is badly clogged, since the system senses restricted airflow and locks out to protect itself. If none of that brings it back on, a licensed contractor can check the igniter, the flame sensor, and the control board.
- Why is my furnace blowing cold air?
- Most often this means the blower is running but the burners haven't lit. Gas furnaces need a spark or hot surface igniter to light the burners, and if that igniter has failed or the flame sensor is dirty, the blower still pushes air through the vents even with no heat behind it. A clogged filter can also cause this, since restricted airflow can trip a limit switch that shuts the burners off while the fan keeps going. If you smell gas at any point, leave the house and call your gas utility before doing anything else.
- Why won't my furnace pilot light stay lit?
- This usually comes down to the thermocouple, the small sensor that tells the gas valve a flame is present. If it's worn out or positioned wrong, it reads no flame even when the pilot is lit, and the gas valve shuts off as a safety measure. A draft in the area, a dirty pilot orifice, or a failing gas valve can cause the same thing. Relighting it yourself is fine to try once, but if it won't hold, a licensed contractor should look at it rather than relighting it repeatedly.
