Air Duct Installation Near Brea, California
Air Duct Installation Near Brea, California
Quiet, even comfort starts with properly designed ductwork.
Great equipment can’t perform with bad ducts. We design to airflow (CFM) and static pressure, then install and seal your system to California mechanical code (and Title 24 duct-leakage testing where required). The result: balanced temperatures, lower bills, and cleaner air.
What’s Included in a Service Lion Duct Install
- Design & sizing: supply/return layout, trunk/branch sizes, register selection
- Materials: rigid metal trunks where appropriate, UL-181 insulated flex for runs, sealed plenums/boots
- Sealing: UL-181 mastic & foil tape at every seam/connection (never cloth “duct tape”)
- Insulation: code-rated R-value for attic/crawl spaces
- Supports & routing: correct strap spacing, bend radius, and clearances
- Balancing: set dampers/flows and verify temperature & pressure after start-up
Materials We Recommend (By Application)
- Rigid metal duct (galvanized): durable trunks, low noise, easy to clean
- Insulated flex duct (UL-181): efficient for branches when sized/routed correctly
- Ductboard/lined plenums: quiet transitions, reduced turbulence at the air handler
We mix materials intentionally for the best balance of performance, sound, and cost.
Signs You Need New Ductwork
- Rooms that never reach the set temperature
- Whistles, rattles, or “oil-canning” from ducts
- Dust streaks around vents/boots (classic leak sign)
- Very high static pressure / noisy blower
- Ducts 20+ years old or visibly damaged in attic/crawl

Add-Ons That Improve Comfort & Air Quality
- Additional/upsized return air for quieter, better airflow
- High-MERV media filter cabinet (we’ll confirm your system can handle it)
- Zoning or balancing dampers for hard-to-condition areas
- Duct sealing of remaining legacy runs; attic insulation coordination
- Condensate safety switches for closet/attic air handlers
Repair vs. Replacement — Which Is Smarter?
Repair/Sealing when damage is localized and ducts are otherwise sized well.
Full Replacement when runs are undersized/poorly routed, insulation is failing, or leaks are widespread — especially with new equipment.
We’ll price both so you can choose based on comfort, lifespan, and budget.

Air Duct Installation FAQs
How long does a duct install take?
Most single-system homes complete in one day; larger homes or added returns can take longer.
Are metal ducts better than flex?
We often use metal trunks for durability/low noise and properly sized, short, straight flex for branches — a smart, quiet, efficient combo.
Will new ducts be quieter?
Yes. Correct sizing, smooth routing, and balancing reduce whistle and rumble, and improve airflow.
Do you pull permits and handle testing?
Yes. We follow local permitting and complete duct-leakage tests where required.
Can you reuse any existing ducts?
If sections are clean, sized right, and in good shape, we can integrate them; otherwise we’ll recommend replacement for performance and air quality.
