Show Low asks a lot of a heating and cooling system
Winter nights here average 21°F from December through February, and homes need heat from October through May, eight months a year. Summer is shorter but real, with afternoons averaging 88°F from June through August. Eleven months out of the year, a system here is either heating the house or cooling it.
Almost a third of homes in this area heat with wood, but a new system still has to carry both jobs on its own when it is asked to. The ten years from 2015 to 2024 brought 137 winter storms and 162 damaging wind events here, and 7% of Arizona households lost power for at least 24 hours in 2024. A new install is worth sizing and setting up for that, not just for a calm day.

Arizona requires HVAC contractors to hold a state license.
Arizona licenses HVAC contractors through the Registrar of Contractors. That license is tested and issued to the contractor, not to each job, so the same license covers this installation as would cover a repair.
For a job like this, the license tells you the contractor was vetted by the state. In most cities and counties, replacing a heating and cooling system also needs a permit from the local building office, with an inspection once the work is done. That inspection checks the system actually installed in your house, separate from whatever the state recorded about the contractor beforehand.

- When should I replace my HVAC system?
- Once repairs start coming often, or the unit is old enough that a licensed contractor tells you the next breakdown is likely, it is time to replace it. In Show Low, homes lean on heat from October through May, so a furnace that fails mid-winter with nights averaging 21°F is a real problem, not just an inconvenience. If your system is limping through its last few winters with band-aid fixes, get it looked at before the cold sets in rather than after it quits.
- Should I replace my furnace and air conditioner at the same time?
- If both units are near the same age, replacing them together often makes sense, but it is not a rule. A furnace and air conditioner installed at the same time wear out around the same time too, so if one is already failing the other may not be far behind. A contractor can check the actual condition of each unit and tell you whether pairing the work now saves you a second disruption later, or whether one of them still has good years left.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or air conditioner in place, and connects it to your ductwork, gas or electrical lines, and thermostat. They check the refrigerant charge on an air conditioner or the gas pressure on a furnace, then run the system to confirm it heats or cools correctly and safely. The exact steps depend on what you're replacing and how your house is set up, so a contractor will walk you through what your specific installation involves.
