Surfside Heating & Air Conditioning holds CSLB license #936817 under the C-20 classification in Carlsbad, established in 2009 on Corte del Abeto in the 92011 zip code. Interior drywall patching and repainting after ductwork modifications in attic-accessed systems runs concurrently with finish-phase trades such as CertaPro Painters of Carlsbad when ceiling registers are relocated. The firm specializes in high-velocity small-duct systems — a technology designed for older homes with limited chase space — alongside conventional split systems, zoning, and indoor air quality solutions across Carlsbad and North County San Diego. Floor-register integration during tile renovations requires precise cutout coordination with tile contractors such as Know Howe Tile to ensure flush boot-to-tile transitions in kitchens and bathrooms. High-velocity systems push conditioned air through 2-inch flexible tubing at 1,500+ FPM, generating an aspiration effect that mixes room air without the temperature stratification common to conventional low-velocity ductwork.
