Your system runs almost year round in Maricopa County
Summer afternoons here average 103°F, and the air conditioner is what stands between the house and that heat for seven months, April through October. The compressor runs long hours day after day, and that kind of load wears on it faster than a mild summer would. When it starts struggling to keep up, you feel it as a house that never quite gets cold, or a unit that runs and runs without the temperature moving.
Winter is short here, November through March, and nights average 41°F, cold enough that the furnace still has to work. Most homes here heat with electricity, so when the power goes out, the heat goes with it. Arizona sees real storms too, 718 damaging wind events over the past ten years. A system already worn from the summer has less left to give when the weather turns on it.

Arizona requires HVAC contractors to hold a state license.
Arizona licenses HVAC contractors through the Registrar of Contractors, and getting that license means the contractor was tested and is on record with the state. The license belongs to the contractor, not to any single job, so it covers the company across every repair it takes on, this one included.
For a heating and cooling repair, that state license is what stands behind the work. It is the thing you can point to if something about the repair was done wrong.

- Why is my heat not working?
- Most heating in Phoenix runs on electricity, so start with your breaker panel before anything else. A tripped breaker or a thermostat set to cool instead of heat causes more no-heat calls than a broken part does. If power is fine and the thermostat is set right, check your air filter next. A filter packed with dust chokes off airflow and can cause the system to shut itself down before it overheats. If none of that explains it, a contractor licensed through the Arizona Registrar of Contractors can find the actual fault.
- Why is my system running but not cooling the house?
- If the blower is running but the air coming out is not cold, check the filter first. A clogged filter starves the coil of airflow, and a starved coil can ice over and stop cooling the air at all. Next check that outdoor unit. If the fan is not spinning or the coil is caked with dirt, the system cannot move heat outside no matter how hard it runs. With Phoenix afternoons hitting 103°F, a system fighting a dirty coil often cannot keep up even when every part is technically working.
- What can I check before calling for HVAC repair?
- Check your thermostat first. Make sure it is set to heat or cool as needed, the batteries are good if it uses them, and the temperature setting is actually different from the room. Next, check the breaker for the system, since a tripped breaker looks exactly like a dead system from the thermostat's point of view. Pull the air filter and hold it up to a light. If you cannot see light through it, replace it. If the outdoor unit has leaves, dirt, or debris packed against it, clear the area around it. If you have done all this and the system still is not heating or cooling, a licensed contractor can take it from there.
