Technician working on attic ductwork ## Replace, repair or seal? A few loose connections or one damaged run can be repaired and sealed. Replacement makes sense when the ductwork is old throughout, poorly insulated, undersized for the system, or damaged in many places. In San Fernando Valley attics, where summer temperatures run far above the outdoor air, uninsulated or leaky ducts lose cooling before it reaches the rooms. California's energy code ties duct sealing and testing to many system replacements ([California Energy Commission](https://www.energy.ca.gov/programs-and-topics/programs/building-energy-efficiency-standards)), so a new AC or heat pump is a good time to fix the ducts too. If the ducts are sound but dirty, [air duct cleaning](https://elviraoceanair.com/air-duct-cleaning-ca/) is enough. ## What to expect during an air duct replacement 1. Inspection and measurement of the existing ducts, airflow per room and the system's capacity. 2. A layout that sizes supply and return runs for each room, with properly insulated duct for the attic. 3. Removal of the old ducts and installation of the new runs, plenums and registers, with sealed connections. 4. Airflow testing at the registers, and duct leakage testing where the code requires it. Technician installing new ductwork ## What affects air duct replacement cost? The number of runs and rooms, attic or crawl space access, duct insulation level, whether the plenums or returns change, and whether the work is done with a new system. Our pricing is up front, with no hidden fees. Pairing duct work with [attic insulation](https://elviraoceanair.com/attic-insulation-ca/) or a new [AC installation](https://elviraoceanair.com/ac-installation-ca/) often saves a second trip into the attic. ## What customers say about Elvira Ocean Air ★★★★★ > "If I could give 20 stars I would. 20 stars for customer service alone."

[on Yelp](https://www.yelp.com/biz/elvira-ocean-air-pasadena) ## Air duct replacement questions How long do air ducts last?It depends on the material, how the ducts were supported and the attic heat; crushed, torn or brittle duct is due for replacement whatever its age. Can ducts be replaced without replacing the AC?Yes. New ducts on an existing system often improve airflow and comfort right away. Do new ducts need a permit?Often yes: in California, duct replacement can bring in the energy code's permit and duct leakage testing rules (California Energy Commission link above).
