Nogales asks a new system to work almost year round
Eleven months a year, a home here needs either heat or cooling. Winter runs November through April, with nighttime lows averaging 33°F, and summer stretches May through September with afternoons near 90°F. A new furnace or heat pump has to hold up through six straight months of cold nights, and the AC side has five months of heat pushing back the other way.
Most homes in Santa Cruz County heat with electricity, so the system has to be sized right for both jobs, not just the one that runs longer. Wind and winter storms both show up on the record here, so whatever gets installed should be able to come back on by itself once the power does.

Arizona requires HVAC contractors to hold a state license.
The Registrar of Contractors tests and licenses the contractor, not the job, so the same license covers this installation and whatever job that contractor takes on next. It's a record the state keeps on the business, not something issued for your address.
That license is what stands behind the person doing the work. The installation itself is a separate matter for your local building office. In most cities and counties in Arizona, replacing a furnace, air conditioner or heat pump needs a permit from that office, and an inspection once the work is done.

- When should I replace my HVAC system?
- Replace it when repairs start coming often, or when the unit is old enough that another breakdown feels like a matter of time. Once a furnace or air conditioner is past its expected lifespan, parts get harder to find and each repair is less likely to hold. If your system is heating or cooling unevenly, running longer than it used to, or you've had a contractor out more than once this year, it's worth getting a real opinion on repair versus replacement instead of waiting for it to fail. Homes here need heat or cooling 11 months out of the year, so a system on its last legs doesn't get much rest.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes. A furnace and air conditioner installed together are matched to work as one system, and pairing a new unit with a much older one often means that older unit fails not long after anyway. Replacing them together also avoids a second round of labor and disruption down the road. If one unit is much newer than the other, a contractor can tell you whether it's worth keeping or whether the mismatch will cause problems.
- What happens during an HVAC installation?
- A contractor first removes the old equipment, then sets the new furnace or air conditioner in place and connects it to the ducts, gas or electrical lines, and condensate drain. They'll check the ductwork itself for leaks or sizing issues, since a new unit can't perform right if the ducts feeding it are wrong for the house. Once it's connected, they test the system through a full cycle, heating or cooling, to confirm it's running the way it should. Arizona requires the contractor doing this work to hold a state license through the Registrar of Contractors.
