Nine months of the year, your system is working
Winter nights average 41°F from December through February, and homes here need heat from November through April, six months a year. Summer afternoons average 82°F, with cooling running July through September. Between the two, a heating or cooling system here is working nine months a year.
That kind of run time is why the installation matters as much as the equipment. A furnace or heat pump sized wrong for the house will struggle through six months of mild but steady cold, and an air conditioner sized wrong will struggle through three months of consistent afternoon heat. Most homes here heat with gas, and whatever goes in needs to be sized to the house, not matched to whatever was there before.

California requires HVAC contractors to hold a state license.
The license is issued to the contractor's business, not to any single job. It is handled through the Contractors State License Board, which keeps the record on file.
For an installation like this, the license is what stands behind the contractor taking on the work. In most cities and counties the job also needs a permit from the local building office, with an inspection once the work is done.

- When should I replace my HVAC system?
- Look at how the system is running right now, not just its age. If your furnace or AC is breaking down most seasons, needs repairs that cost more each time, or can't keep the house at a steady temperature, it's time to start pricing a replacement. An older system is a bigger risk to keep repairing, especially heading into the months here when you'll need it most, November through April for heat and July through September for cooling. A contractor can look at your specific system and tell you whether another repair makes sense or whether you're past that point.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it usually makes sense to do them together. A furnace and AC installed years apart wear at different rates, but once one is failing, the other often isn't far behind. Doing them at the same time also means the whole system, the furnace, the coil, the outdoor unit, is matched and sized to work together, which isn't always true when you replace one piece and leave the other. That said, if one unit is much newer than the other, a contractor can tell you whether it's worth keeping for now.
- What happens during an HVAC installation?
- A contractor removes the old equipment first, then sets the new furnace, air conditioner, or both in place. The ductwork gets connected, along with the refrigerant lines, gas line, and electrical connections the new equipment needs. Once everything is hooked up, the contractor tests the system, checks refrigerant levels and airflow, and walks you through the thermostat and anything else specific to your setup. In California, the contractor doing this work has to hold a license through the Contractors State License Board, so it's worth confirming that before work starts.
