Expert Duct Repair, Replacement & Installation in Marin County and San Francisco
Your home’s ductwork is the backbone of your HVAC system, delivering heated or cooled air to every room. Leaks, damage, or outdated ducts can waste energy, raise utility bills, and degrade indoor air quality (IAQ). At Bay Air Heating & Cooling, we provide professional duct repair and installation services to optimize efficiency and comfort for homeowners in Marin County and San Francisco.
Our certified technicians use advanced diagnostics, like duct pressure testing, to identify issues and deliver tailored solutions, from sealing leaks to installing new, energy-efficient duct systems. Backed by a one-year 100% satisfaction guarantee, our services can save up to 30% on energy costs, per the U.S. Department of Energy.
Ductwork Wear and Tear
Aging ducts, seams, and joints wear out due to:
- Thermal Expansion: Constant heating and cooling cycles cause ducts to expand and contract, loosening connections and creating leaks.
- Moisture Exposure: In uninsulated spaces like attics or crawl spaces, humidity can cause rust or corrosion, weakening metal ducts.
- Material Wear: Older ducts may be undersized or incompatible with modern high-efficiency HVAC systems, reducing performance.
Leaky ducts can waste up to 30% of conditioned air, per the EPA, increasing energy bills and pulling in pollutants like dust, pollen, or mold spores, which harm IAQ. Our team assesses your ductwork’s condition and recommends repairs or replacements to restore efficiency and air quality.
5 Signs You Should Replace Your Ductwork
Replacing ductwork can significantly improve comfort, IAQ, and HVAC efficiency. Here are five key indicators your home needs new ducts:
- Age Over 15 Years: Ducts older than 15 years often have weakened seals and reduced efficiency, per Direct Energy.
- Persistent Dust or Allergies: Excessive dust or worsened allergies at home suggest leaks pulling in contaminants.
- Uneven Temperatures: Rooms that are too hot or cold indicate poor airflow from damaged or undersized ducts.
- Visible Damage: Crushed, kinked, or corroded ducts restrict airflow and require replacement.
- Musty Odors: A strong, unpleasant smell when your HVAC runs may signal mold or debris in ducts.

Maintenance Tips for Ductwork Longevity
Regular maintenance extends ductwork life and efficiency:
- Annual Inspections: Check for leaks, corrosion, or damage using visual or pressure tests.
- Filter Replacement: Swap MERV 8-12 filters every 1-3 months to reduce dust buildup.
- Duct Cleaning: Schedule every 3-5 years to remove allergens and debris.
- Insulation Checks: Ensure insulation remains intact in unconditioned spaces.
