Eleven months of work, in a place where the power doesn't always stay on
Clifton only gets a break from heating or cooling for about a month a year. Furnaces run October through April, with winter nights averaging 29°F, and air conditioners take over June through September, when afternoons average 88°F. Most homes here heat with gas, so that furnace is doing real work on those cold nights, cycling on and off to keep up. Each start puts wear on the igniter and the burner. When one of those parts finally gives out, the house goes cold on a night when you need it most.
Greenlee County has seen 26 winter storms and 15 damaging wind events over the past ten years, and statewide, 7% of households lost power for at least a day in 2024. A furnace or air conditioner that loses power and comes back on usually restarts fine on its own, but the stress of storms and outages adds up on top of the system's regular workload. When something is already worn from months of steady use, that is often when it fails.

A new furnace and air conditioner would cut about $150 a year off heating and cooling for a typical Greenlee County home.

Repair makes sense when one part has failed.
Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.
Arizona requires HVAC contractors to hold a state license.
Arizona's license is handled through the Registrar of Contractors. It covers the contractor as a whole, not each individual job, so the same license applies to this repair and to any other job that contractor takes on.
For a repair on a heating and cooling system, that license is what stands behind the person doing the work.

- Why is my heat not working?
- Start with the thermostat. Check that it's set to heat and set higher than the room temperature, and that the batteries aren't dead. If the thermostat looks right, check your breaker panel. A furnace that won't start at all often points to a tripped breaker, a blown fuse, or an igniter that's failed. Gas furnaces also need a pilot light or an electronic ignition to succeed, so if you smell gas at all, stop and get a contractor out rather than trying to relight anything yourself. If the furnace runs but blows cool air, a clogged filter or a failed inducer motor can be behind it.
- 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 stop cooling the air at all. Next check the outdoor unit. If the condenser coil outside is covered in leaves, grass clippings, or dirt, it can't release the heat it's pulling from your house, and the whole system loses its ability to cool. Low refrigerant is another common cause, but that's not something to check yourself. It takes a gauge set and a licensed contractor to find and fix a leak.
- What can I check before calling for HVAC repair?
- Check the thermostat settings and batteries first. It sounds basic, but a thermostat set to the wrong mode or with dead batteries looks exactly like a broken system. Then check the air filter. A filter that hasn't been changed in months restricts airflow enough to cause icing, poor cooling, or a furnace that overheats and shuts itself off. After that, check your breaker panel for a tripped breaker, and if you have a gas furnace, make sure the gas valve is open. If everything there checks out and the system still isn't working, that's when it's time for a contractor. In Arizona, HVAC contractors are required to hold a state license through the Registrar of Contractors, so it's worth confirming that before anyone comes to look at your system.
