In Prescott Valley, a new system works nearly all year
Winter nights here average 31°F from December through February, and homes need heat from October through April. That's seven months the furnace or heat pump is the only thing standing between the house and the cold. Summer afternoons average 93°F, and cooling runs June through September, four more months of work. Between the two, a heating and cooling system here is on the job 11 months.
Almost half the homes in the area heat with gas, so the furnace side of a new system matters as much as the air conditioner side. Whatever goes in has to hold up to both ends of that range, the 31°F nights and the 93°F afternoons, with barely a month between one season and the next.

Arizona requires HVAC contractors to hold a state license.
The Registrar of Contractors licenses the contractor, not the job. That means the state tested this contractor before letting them take work, and the license stays tied to them from one job to the next rather than being issued fresh each time.
For this installation, that license is what stands behind the person doing the work. The job itself still gets checked separately. In most cities and counties, putting in a new furnace, air conditioner or heat pump needs a permit from the local building office, and an inspector looks at the finished work before it is signed off. That inspection is where a bad gas connection or a wiring mistake gets caught, apart from anything the license covers.

- When should I replace my HVAC system?
- Replace it when repairs start happening every year, or when the repair itself costs a large share of what a new system would run. Age matters too. A furnace or air conditioner working hard for many winters and summers is more likely to fail at the worst time, and here that means a December or February night near 31°F or an afternoon anywhere from June through September near 93°F. If your energy bills have been climbing while the equipment runs longer to hold the same temperature, that is another sign it is losing efficiency, not just getting old. A contractor can look at the specific unit and tell you whether another repair makes sense or whether replacement is the better move.
- Should I replace my furnace and air conditioner at the same time?
- If they are close in age, yes, it usually makes sense to do both together. A furnace and air conditioner installed at the same time are matched to work as a pair, and replacing one now while planning to replace the other later often means paying for a second round of labor and running mismatched equipment in the meantime. Homes here need heat from October through April and cooling from June through September, so both sides of the system get real use nearly all year. If one unit is much newer than the other, a contractor can tell you whether it is worth keeping for now or whether replacing both still makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, or the parts being replaced, and checks the ductwork, electrical connections and gas or refrigerant lines to make sure they suit the new equipment. The new furnace and outdoor condenser get set in place, connected to the ducts, wiring and, for gas furnaces, the gas line. Once everything is connected, the contractor tests the system through a full heating and cooling cycle to check airflow, temperature output and that all the safety controls are working. The whole job is inspected against the local building code before it is considered complete.
