Westminster Ducts, Done Right
Westminster's housing stock — spread across neighborhoods like Little Saigon, the Sigler Park area, and the communities near Barber City — leans heavily on aging duct systems that were sized for smaller households than the city's current average of 3.26 people per home. With a population of over 90,000 and a near-even split between owners and renters, the demand Shalom Heating & Air sees here runs the full range: from single-family homes with original flex duct that's decades old to commercial properties near the Westminster Mall area where air distribution problems quietly drive up energy costs.
Shalom Heating & Air handles ductwork repair, replacement, and installation throughout Westminster, CA, including Little Saigon and the Westminster Mall area. With roughly half of Westminster's 27,700 households owner-occupied and average household sizes of 3.26 people, properly sized and sealed ducts matter. Call (714) 886-2021.

What older Westminster ducts hide
A significant share of Westminster's residential neighborhoods were built out in the 1960s and 1970s, and many of those original duct systems are still in place — wrapped in materials that have long since degraded, with connections that have loosened over decades of thermal cycling. In areas like Little Saigon and the Sigler Park neighborhood, Shalom Heating & Air regularly uncovers duct runs that are losing a substantial portion of conditioned air before it ever reaches a living space. The result shows up as uneven temperatures from room to room, systems that run longer than they should, and utility bills that don't match the thermostat setting. A proper duct assessment is the starting point — not a guess.
- ✓Aging flex duct that has collapsed, kinked, or separated at joints
- ✓Fiberglass duct board with deteriorated inner liner and air leakage
- ✓Undersized trunk lines that can't meet today's household load demands
- ✓Disconnected or improperly supported duct runs in attic and crawl spaces
- ✓Mastic or tape seals that have dried out and no longer hold
- ✓Return air pathways that were never properly sized for the system
Every duct service, one call
Whether a Westminster property needs a targeted repair on a single disconnected run or a full system replacement from air handler to registers, Shalom Heating & Air handles it under one call. The city's mix of owner-occupied and renter-occupied homes — roughly 52% and 48% respectively — means the work spans everything from careful attic replacements in long-held family homes near Liberty Park to coordinated commercial duct retrofits near the Westminster Mall area. Every project starts with a written estimate, and the scope is always explained clearly before any work begins.
- ✓Duct leak detection and sealing with mastic or UL-listed foil tape
- ✓Partial duct replacement targeting damaged or undersized sections
- ✓Full duct system replacement with properly sized trunk and branch lines
- ✓New ductwork installation for additions, conversions, or new HVAC systems
- ✓Ductless mini-split installation where traditional duct runs aren't practical
- ✓Ductwork for commercial spaces including retail and office properties


Permits through Westminster's own department
Westminster is an incorporated city, which means all mechanical permits — including ductwork that requires a permit — go through the City of Westminster's own building and planning department, not a county office. Shalom Heating & Air is CSLB licensed (#967182) and handles the permit coordination process directly, so Westminster homeowners and property managers near zip codes 92683, 92684, and 92685 aren't left navigating the city's requirements on their own. Not every duct repair triggers a permit requirement, but full replacements and new installations typically do — and getting that right protects the property and keeps the work code-compliant.
- ✓Mechanical permits pulled through the City of Westminster building department
- ✓CSLB license #967182 on file — meets city contractor requirements
- ✓Inspection scheduling coordinated around the property's availability

Ductwork replacement is one of the higher-cost HVAC projects a Westminster homeowner faces, but California's rebate programs and Shalom Heating & Air's financing options can make the investment more manageable. Depending on the scope of work and the equipment involved, meaningful California HVAC rebates may be available — and Shalom's team walks customers through what applies to their specific project.
