Four months of real heat, every year
Fresno County summers push into June and don't let go until September ends. Afternoons average 86°F across those four months, and a new air conditioner has to hold steady through all of it, day after day, without a break to recover.
Any new central air conditioner installed today has to meet 14.3 SEER2, the federal efficiency minimum. That's the baseline a licensed contractor will size and install to, matched to your home rather than the old system it's replacing.

California requires HVAC contractors to hold a state license.
The Contractors State License Board tests and records HVAC contractors before they can hold a license, and that license belongs to the contractor, not to any one job. So the license you check is the company's, and it stays valid or not across every job they take on, not just this one.
For an air conditioner installation in Fresno County, the license tells you the person doing the work has passed the state's test and is on record with the CSLB. Beyond that, most cities and counties in California require a permit for this kind of installation, along with an inspection once the work is finished. That inspection is what checks the work itself, separate from whatever the contractor's license already covers.

- What size air conditioner does my house need?
- The right size depends on your square footage, your ceiling height, how much shade your house gets, and how well it's insulated, so there's no single number that fits every home. A unit that's too big cools the air fast but shuts off before it pulls the humidity down, so rooms feel clammy. A unit that's too small runs constantly on the hot afternoons here and never quite catches up. A contractor will walk through your house and run a load calculation to get the right size for your specific home.
- Should I replace the whole system or just the outdoor unit?
- In most cases you want to replace both the outdoor unit and the indoor coil together. The two are matched to work at a specific efficiency, and pairing a new outdoor unit with an old coil usually means you lose much of the efficiency gain you paid for. It also puts strain on the new compressor since the old coil wasn't built to handle it. A contractor can look at the age and condition of your indoor coil and tell you whether it's still a good match.
- Do HVAC contractors in Fresno need a state license to work on my home?
- Yes. California requires HVAC contractors to hold a state license, issued by the Contractors State License Board. Ask to see the license number before work starts, and you can look it up with the board to confirm it's active and covers the work you need done.
