Altitude Derating Applied
We pull the maker's derating table for every unit we quote. We size up as needed so your home stays cool on a 90°F July day. The right ton rating is the only one that works here.
AC Setup · Kings Beach, CA
Kings Beach sits at 6,444 ft. AC units lose 15 to 20 percent of their rated output at that height.

AC units are rated at sea level. At 6,444 ft, air is thin. A unit that cools a 2,000 sq ft valley home may fall short of the same home in Kings Beach. The math changes at altitude. Fresh Air checks each unit's altitude correction data before sizing your job. Out-of-area crews often skip this step. We don't. Free estimate. Since 2009.

An undersized unit runs all day and still falls short. You find out on the hottest day of the year. Fresh Air prevents this by sizing for Kings Beach elevation, not for the valley.
We visit your Kings Beach home first. We check sun exposure, insulation, and room count. Your quote reflects your real home at your real elevation.
Air density at 6,444 ft is roughly 79 percent of sea-level density. That means each cubic foot of air carries less heat. An AC unit moves heat by blowing air over a coil. Thinner air equals less heat moved per fan cycle. The unit must run longer to cool the same space. Manufacturers account for this in their spec sheets. Fresh Air uses those sheets.
Contractors who work only in the valley rarely check altitude specs. They install a 3-ton unit because a 3-ton unit fits the square footage. At Kings Beach, a 3-ton sea-level unit may deliver closer to 2.5 tons of real output. Fresh Air sizes for the corrected output, not the label. License #945361. Insured. Since 2009.
Most homes run $4,500 to $12,000 for central AC. High-altitude sizing may add a unit size tier to the quote. Your free estimate gives the honest number.
Not a special unit type. You need one with enough rated capacity so that its altitude-adjusted output still meets your home's load. We calculate that for you.
Kings Beach falls in Placer County. Fresh Air pulls the permit with the county and books the inspection. That's included in every job we do.
