Twelve months of work, most of it in the heat
Your air conditioner runs from April through October in Maricopa, seven months of summer afternoons that average 101°F. The compressor works hardest right when the sun is hardest on your roof, and it does that day after day for most of the year. That kind of run time wears on the capacitor and the condenser fan first. You notice it as warm air from the vents, or the system running longer to hold the same temperature.
Winter is shorter here, November through March, and the nights average 40°F from December through February. The furnace or heat pump cycles on and off far less than the AC does, and a system that sits idle for months can be slow to start when it finally gets called on. Wind is the other thing this place deals with, 150 damaging wind events recorded here over the past ten years. That kind of wind gets at the outdoor unit and its wiring, and it shows up as a tripped breaker or a system that won't start at all.

Arizona requires HVAC contractors to hold a state license.
Arizona's license is issued through the Registrar of Contractors, and it covers the contractor as a business, not each job. The same license applies whether the work is a repair, a full install, or a service call, so it does not change based on what is being done to your system.
For a repair like this one, that license is what stands behind whoever comes to work on your heating and cooling system. It tells you the state has that contractor on record.

- Why is my heat not working?
- Most often it comes down to power, gas, or airflow. If you heat with electricity, check the breaker first since a tripped one is common after a storm. If your furnace runs on gas, the igniter or the flame sensor is a frequent failure point, and either one will stop the burners from lighting even though the blower still runs. A clogged filter can also choke the system enough that it shuts itself off to protect the heat exchanger, so check that before anything else.
- Why is my system running but not cooling the house?
- If the blower is moving air but that air is not cold, the problem is usually the refrigerant side or the coil, not the fan. A dirty filter or a blocked return can starve the coil of airflow, and when that happens the coil can ice over and stop cooling even though the fan keeps running. Low refrigerant from a leak does the same thing. On a 101°F afternoon this shows up fast, since the system has no margin to work with once airflow or refrigerant is off.
- What can I check before calling for HVAC repair?
- Start with the filter. A filter clogged enough to block airflow can cause both heating and cooling problems, and it's the one thing you can fix yourself in a few minutes. Next check the breaker and any switch near the furnace or air handler, since a tripped breaker or a flipped switch will stop the system cold. If you have a programmable thermostat, confirm it's set to heat or cool as intended and that the batteries aren't dead. If those check out and the system still isn't working, it's time to have a licensed contractor look at it. Arizona requires HVAC contractors to hold a state license through the Registrar of Contractors, so ask for that before letting anyone work on your system.
