What the climate around San Jose means for windows
For homes around San Jose, heating dominates: prioritize a low U-factor and tight air leakage on the NFRC label, because limiting winter heat loss is where window performance pays off here. The station's annual mean temperature is near 62°F with about 16 inches of precipitation, so flashing and water management around the opening deserve the same written attention as the glass package.
Climate figures are NOAA 1991-2020 normals recorded at SAN JOSE, CA US (near San Jose); they describe the recording station's location, not any specific property.
Comparing window performance the measurable way
California's ENERGY STAR Version 7.0 zone criteria (Northern: U-factor ≤ 0.22, SHGC ≥ 0.17; North-Central: U-factor ≤ 0.25, SHGC ≤ 0.40; South-Central: U-factor ≤ 0.28, SHGC ≤ 0.23; Southern: U-factor ≤ 0.32, SHGC ≤ 0.23) set the qualifying levels; the county's zone determines which applies to a San Jose home. Whole-product NFRC ratings on the exact quoted window are the comparable basis, and no rating supports a guaranteed savings figure for an individual home.
Planning ranges for San Jose
The published Window Replacers planning range for a representative whole-home replacement scenario in the San Jose area is $550–$1,375 per opening, produced by the versioned pricing methodology from official labor and regional price data. A planning range is not a quote: only a written proposal from a professional who has evaluated the specific openings can state a price.
See the cost methodology for how planning ranges are built.
Openings, scope, and what belongs in writing
Before comparing whole-home replacement proposals in San Jose, document the openings themselves: number and variation of openings; product consistency and custom configurations. Homes built before 1978 add a federal consideration: work that disturbs painted surfaces falls under the Renovation, Repair and Painting rule, so confirm the construction year and ask how containment will be handled.
