Altitude Sizing Audit
Before we pick a new unit, Fresh Air checks the old unit's specs against your home's load at altitude. If the old unit was undersized, we flag it. The new unit is sized to work at 6,000 feet.
AC Replacement in Truckee, CA
Truckee vacation homes often got AC sized by valley crews who skipped altitude derating. The unit falls short on hot days. Fresh Air audits the old sizing before picking a new unit.

Truckee is at about 6,000 feet in the Sierra Nevada. Some vacation homes here had AC put in by valley crews who did not adjust for altitude. The result is a unit that cannot keep up on warm summer days. Fresh Air reviews the old sizing before recommending a new unit for Truckee homes.

A valley crew sizing AC for a Truckee home may use the same method they use in Sacramento. At sea level, 2,000 square feet may need a 3-ton unit. At 6,000 feet, that same home may need 3.5 tons to match it. Altitude derating is the gap. It is easy to miss if you do not know to look.
Fresh Air checks the old unit's size against the altitude-corrected load. If the old unit was undersized, the new one fixes that. If the old spec was correct, we match it. Truckee owners get a unit that cools from the time they arrive, not one that runs for hours just to get close.
At 6,000 feet, thin air cuts AC output by about 20 to 24 percent versus sea level. A unit sized without this fix will fall short on hot days. Fresh Air applies altitude derating to every Truckee estimate.
Yes. We set up access and a schedule with the owner in advance. We send status updates and use milestone billing so payment ties to finished stages. No need to be on-site.
