Eleven months of work for a new system in Parker

Summer afternoons here average 105°F, and homes need cooling for seven months, April through October. Whatever system goes in has to hold up to that heat most of the year, not just get through a few hot weeks. Winter is shorter but still real. Nights average 42°F from December through February, and homes need heat for four months, November through February.

Most homes in Arizona heat with electricity, and the grid here isn't guaranteed. Statewide, 7% of households lost power for at least 24 hours in 2024, and this area has recorded 32 damaging wind events over the past ten years. A new install is worth planning with that in mind.

Arizona requires HVAC contractors to hold a state license.

The Registrar of Contractors tests contractors before they get a license, then keeps a record of who holds one. That license belongs to the contractor, not to any single job, so it stays in place from one installation to the next rather than being issued fresh each time.

For a heating and cooling installation, the license tells you the contractor who takes on the work has been tested and is on record with the state. The installation itself still needs a permit from the local building office in most cities and counties, along with an inspection once the work is done. That permit and inspection are a separate check, done at the local level, on top of whatever the state license already tells you about the contractor.

When should I replace my HVAC system?
Replace it when repairs start happening every year or the unit can't keep up anymore. An older air conditioner or furnace working past its prime shows up as higher bills and rooms that never quite reach the temperature you set. With summer afternoons here hitting 105°F, a weak or failing system doesn't just cost more, it leaves you without reliable cooling on the days you need it most. If a contractor has already been out more than once this year, get a straight opinion on whether the next repair is worth it or whether the money should go toward a new system instead.
Should I replace my furnace and air conditioner at the same time?
If both are old, yes. Your furnace and air conditioner share the same ductwork and, in many systems, the same blower, so they're built to work as a matched pair. Replacing only one means pairing new equipment with an aging match, and it can end up never running quite as efficiently as it should. Homes here need cooling for 7 months and heat for 4, so both halves of the system see real, regular use and tend to wear out on a similar timeline. A contractor can tell you if your furnace and AC are close enough in age that replacing them together makes sense.
What happens during an HVAC installation?
A contractor removes the old equipment, sets the new furnace and or air conditioner in place, and connects it to your ductwork, electrical, gas line, and, for an air conditioner, the refrigerant lines. They'll check that the ductwork is sized correctly for the new equipment, since a system that's too big or too small for your home's ducts won't heat or cool evenly. Once it's connected, they test the system, check refrigerant levels and airflow, and make sure the thermostat is communicating properly with the new unit. Because Arizona requires HVAC contractors to hold a license through the Registrar of Contractors, ask to see that license before the work begins.
