Ten months of work, most of it in the heat
Your air conditioner runs from April through October here, working against afternoons that hit 105°F. That kind of heat load runs the compressor hard for seven months straight, and it's the condenser fan motor and the capacitor that tend to give out first. You'll notice the air coming out warm, or the unit running long stretches without shutting off.
Winter is short here, just December through February, with nights averaging 43°F. The furnace or heat pump doesn't get the workout the AC does, but it still has to fire up reliably on the cold nights, and a system that sat idle for months is where a weak igniter or a stuck component shows up first. Most homes here heat with electricity, so when the power goes out, the heat goes with it. Statewide, 7% of households went at least 24 hours without power in 2024, and this area has seen 61 damaging wind events over the past ten years. Worth keeping in mind if your heat or air depends on the grid staying up.

Arizona requires HVAC contractors to hold a state license.
The Registrar of Contractors tests contractors before they get that license, and keeps a record of who holds one. That license belongs to the contractor, not to any single job, so the same license that qualifies someone to install a system also qualifies them to repair one.
For a repair on a heating and cooling system, that license is what stands behind the work. It means the person working on your furnace or your AC has been tested by the state, and there is a record of them at the Registrar of Contractors.

- Why is my heat not working?
- Most of the time it comes down to the thermostat, the igniter, or airflow. Check that the thermostat is set to heat and the temperature is above room temperature, since a setting bumped by accident is common. If the thermostat looks right, check the air filter. A clogged filter can choke off airflow and cause the furnace to shut itself down before it ever warms the house. Winter nights here average 43°F, so a furnace that will not stay on can make a house cold fast, and a licensed contractor can find the exact cause.
- Why is my system running but not cooling the house?
- The system running without cooling usually points to the outdoor unit or the airflow inside. Check the air filter first, since a filter packed with dust blocks air from moving through the coil and can cause it to ice over. Also look at the outdoor unit and clear away any leaves, dirt, or debris around it, because it needs open airflow to release heat. If the filter is clean and the outdoor unit is clear, the system likely has a refrigerant or electrical problem that needs a licensed contractor to diagnose, especially with afternoons here reaching 105°F.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it is set to the right mode and the batteries are not dead, since a thermostat with no power will not call for heat or cooling at all. Next, check the air filter and replace it if it looks gray or clogged. Then check the breaker panel for a tripped breaker, since both furnaces and air conditioners run on electricity and a tripped breaker will stop the system cold. If the system still is not working after that, a licensed contractor can take it from there.
