Ductwork Built for Norwalk's Busy Households
Norwalk's owner-occupied neighborhoods — from the established blocks of Old Town Norwalk and Carmenita to the Studebaker Road Corridor — are home to large households averaging 3.74 people, and aging duct systems in those homes often can't keep pace. Shalom Heating & Air brings full-service ductwork repair, sealing, and installation to all of Norwalk's 101,893 residents, with the straightforward estimates and honest scoping that homeowners here expect.
Shalom Heating & Air handles ductwork repair, sealing, and full replacement for Norwalk homes and businesses across zip codes 90650 and 90651. With roughly 68% owner-occupied households and an average of 3.74 people per home, Norwalk properties put real demand on duct systems. Call (714) 886-2021.

What older Norwalk homes hide in the attic
A large share of Norwalk's housing stock dates to the postwar building boom of the 1950s and 1960s, when ductwork was installed with materials and sizing standards that have long since been superseded. In neighborhoods like Old Town Norwalk and the Shoemaker area, it's common to find original flex duct that has collapsed in sections, fiberglass duct board that has separated at the seams, or undersized trunk lines that were never designed to cool a home the way modern air conditioners demand. With roughly 67.6% of Norwalk's 26,508 households owner-occupied, many of these systems have been patched over the decades rather than properly replaced — and those patches tend to fail quietly, costing homeowners in energy waste and uneven comfort long before anyone notices. Shalom Heating & Air starts every ductwork call with a thorough inspection so you know exactly what you're dealing with before any work begins. Call (714) 886-2021 to schedule yours.

Every duct service Norwalk properties need
Norwalk properties range from compact single-family homes near Gerdes Park and Zimmerman Park to larger multi-room residences in the El Camino Village and Carmenita communities, and the right ductwork solution depends entirely on what the building actually has. Shalom Heating & Air handles the full range — from targeted duct sealing on systems that are structurally sound but leaking, to partial section replacement where damage is isolated, to complete duct system replacement when the existing layout can no longer support the home's heating and cooling load. We also install ductless mini-split systems for additions or rooms that were never connected to the central system, and we repair or replace duct insulation that has degraded in Norwalk's warm summers. Whatever the scope, you get a free written estimate before any work is authorized. Call (714) 886-2021.
- ✓Aeroseal or mastic duct sealing for leaky but intact systems
- ✓Partial duct section replacement for localized damage or collapse
- ✓Full duct system replacement with properly sized trunk and branch lines
- ✓Duct insulation repair and upgrade for attic runs
- ✓Ductless mini-split installation for additions and unconverted spaces
- ✓Return-air upgrades to balance systems after AC or furnace replacement


Sizing ducts for Norwalk's household density
At an average household size of 3.74 people — well above the regional norm — Norwalk homes run their HVAC systems harder and longer than the equipment was often sized to handle. In the Norwalk Arts and Sports Complex area and along the Studebaker Road Corridor, we regularly find duct systems that were adequate for a two-person household in 1965 but are now serving families of five or six, with bedrooms added, garages converted, and window units supplementing a central system that can't reach the back of the house. Proper duct sizing isn't just about comfort; it directly affects how hard your AC or furnace has to work, how long the equipment lasts, and what you pay to run it every month. Shalom's ductwork scoping accounts for the actual occupancy and layout of your Norwalk home, not a generic square-footage formula. Call (714) 886-2021 to talk through what your home needs.
- ✓Manual D duct sizing calculations matched to your home's actual layout
- ✓Assessment of added rooms, conversions, or extensions not on original plans
- ✓Identification of undersized return-air grilles limiting system airflow
- ✓Zoning options for multi-story or multi-wing Norwalk homes
- ✓Coordination with new AC or furnace installs to match duct capacity
- ✓Indoor air quality add-ons (filtration, ventilation) integrated into new duct runs
Permits through Norwalk's own building department
- ✓Permit applications filed with the City of Norwalk Building Department
- ✓Mechanical code compliance for all new duct installations
- ✓Inspection scheduling coordinated around your availability
- ✓Documentation provided to homeowner after final inspection sign-off
- ✓Guidance on what scope of duct work triggers a permit requirement
- ✓No permit surprises — scope and requirements discussed upfront in writing
Norwalk is an incorporated city with its own building and planning department, which means ductwork permits and inspections are handled locally — not through the county. For full duct replacements and new duct installations, a permit is typically required, and the City of Norwalk's inspectors will want to verify that the work meets California mechanical code before the system is closed up. Shalom Heating & Air handles the permit coordination on your behalf so you're not navigating the city's process on your own. We pull the permit, schedule the inspection, and make sure the finished system passes — which also protects you if you ever sell the home or file an insurance claim. If you're in the 90650 or 90651 zip codes and unsure whether your specific project requires a permit, the straightforward answer is to call us first. Call (714) 886-2021.
Making duct upgrades affordable in Norwalk
A full duct replacement is one of the larger HVAC investments a Norwalk homeowner can make, but California's rebate programs and Shalom's financing options make it more manageable than most people expect. Depending on the equipment connected to the new duct system and the utility provider serving your Norwalk address, substantial California HVAC rebates may be available — and Shalom's team will walk you through what your specific project qualifies for. For the remaining balance, we offer flexible financing including same-as-cash and 0% APR plans, so a properly sized duct system for a home near Old Town Norwalk or the Carmenita neighborhood doesn't have to wait until you've saved the full amount. We also provide a best-price guarantee: bring us a reasonable written competitor estimate and we'll meet or beat it.
