How do I know if my ducts are leaking?

Should I have my ducts cleaned?

Duct cleaning may be beneficial if you see visible mold, excessive dust, or pest infestation. For most homes, changing filters regularly and sealing leaks is more important than cleaning. Call (925) 578-3379 for a free San Ramon estimate — we serve all Contra Costa County neighborhoods.

Why Choose Professional Ductwork in San Ramon?

San Ramon's corporate campus character and primarily 1980s-2000s housing stock creates a ductwork profile different from older Bay Area cities: most homes have duct systems that were part of the original construction rather than retrofits, installed under the building standards of those decades. Gale Ranch and Dougherty Valley neighborhoods from the 2000s have the newest ductwork; Bishop Ranch area residential neighborhoods from the 1980s have systems that are now 35-40 years old. The San Ramon Valley's warm inland climate creates demanding attic conditions that affect duct performance across all home ages.

For Gale Ranch and Dougherty Valley homes from the 2000s: even relatively new ductwork benefits from post-installation leakage verification. California Title 24 compliance testing occurs at installation, but thermal cycling in San Ramon's warm valley climate over 15-20 years can loosen connection joints that passed initial testing. Galaxy's ductwork assessment provides current leakage rates and identifies any developing leakage before it becomes a significant efficiency problem. For Bishop Ranch area residential neighborhoods with 1980s ductwork: these 35-40 year old systems are at or past the expected lifespan of flexible duct in the thermal environment of the San Ramon Valley. Flex duct jacket deterioration, connection joint loosening, and insulation compression reduce both tightness and thermal performance. Galaxy's assessment establishes whether repair and sealing is cost-effective or whether full duct replacement provides better long-term value. The replacement uses modern R-8 insulated flex duct with mastic-sealed connections at all joints. For all San Ramon homes: duct testing provides the before-and-after documentation that enables homeowners to measure the performance improvement from ductwork investment — Galaxy provides this testing as part of every ductwork project.

San Ramon Climate & HVAC: San Ramon regularly experiences hot, dry summer weather, so cooling capacity and airflow must be evaluated for peak conditions. Mild winters make both all-electric heat pumps and dual-fuel systems practical options, depending on the home and homeowner's priorities.

From master-planned communities like Windemere and Gale Ranch to established neighborhoods in Crow Canyon to newer developments in Dougherty Valley, San Ramon's high-quality housing serves professional families.

San Ramon Neighborhoods We Serve for Ductwork

Our technicians know San Ramon's neighborhoods well — every street, housing era, and local quirk that affects your HVAC system. Here's where we regularly provide ductwork services:

Windemere

Multi-story planned homes where zoning, return-air capacity, and balancing can matter for even temperatures between floors

Gale Ranch

Larger floor plans where accurate load calculations and properly matched indoor and outdoor equipment help avoid short cycling and uneven comfort

Dougherty Valley

Many 2000s-era homes have original builder-grade systems approaching replacement age, making duct, electrical, and equipment-clearance reviews important

Crow Canyon

Established homes where aging furnace-and-AC combinations may benefit from repair-versus-replacement and dual-fuel evaluations

Bollinger Canyon

Larger homes and longer duct runs can require room-by-room load analysis, airflow testing, and careful zoning design
