What Customers Say About Our Duct Services in the Bay Area?

Had the plumber Daniel come to my condo today for a clogged toilet. He spent almost two hours snaking with a camera my drain and pulled out a huge clog of tree roots. He knew exactly what he was doing and did a wonderful job. I would recommend this company very much.

Ron K.

Great, reliable, and timely service at a reasonable price. I shopped around quite a bit before landing on CPI. Their rates were competitive, they responded promptly, and their plumber fixed a few issues quickly and without much fuss. I’ll definitely be calling them again the next time we have issues!

Allan Huynh

CPI Service was sent to my home by my condominium association. They agreed to a very early morning appointment and the gentleman arrived exactly on time. He went through the problem very methodically to see where the problem was. Something that no one else could figure out was taken care of in half an hour. I would very definitely recommend them.

Benefits of Installing New Ducts

Better Indoor Air Quality: Upgrading to new ductwork helps reduce the circulation of dust, mold, and allergens, leading to fresher and healthier air inside your San Francisco home. Properly sealed ducts keep contaminants out, creating a cleaner environment that is especially beneficial for families dealing with asthma or allergies.

Reduced Repair Needs: Modern ducts are built to last, which means fewer breakdowns and less maintenance compared to aging or damaged ductwork. By replacing worn-out sections, homeowners in San Francisco can avoid recurring repair costs and keep their HVAC system running smoothly for longer.

Consistent Comfort: New duct systems are designed for balanced airflow, eliminating hot and cold spots throughout your home in San Francisco. With leaks and blockages removed, upgraded ducts deliver steady temperatures, providing dependable comfort in every room year-round.

Extended HVAC Lifespan: Well-installed ducts ease the workload on your heating and cooling equipment. By maintaining proper airflow and temperature control, they reduce strain on your system, extending its lifespan and improving long-term reliability in San Francisco properties.

Energy Savings: Sealed and efficient ductwork minimizes wasted energy, cutting down on heating and cooling expenses. With improved airflow, your system does not have to work as hard, helping lower monthly utility bills and keeping your San Francisco home comfortable.

Common Signs Before You Need Duct Services

Leaks or Holes: Visible leaks in San Francisco homes cause air loss, lowering efficiency and raising utility bills. Gaps in the ductwork force your HVAC system to work harder as conditioned air escapes into walls or crawl spaces. CPI Service uses advanced diagnostics to detect these issues and provide precise repair or replacement solutions.

Aging Ductwork: Ducts over 15-20 years old often sag, rust, or break down. Once wear or severe damage appears, inspection and replacement are strongly recommended. CPI Service delivers honest assessments and reliable upgrades to restore airflow and performance.

Poor Airflow: Weak or uneven airflow in your San Francisco home may signal leaks, blockages, or collapsed ducts. These problems reduce comfort and strain your system. Our technicians perform detailed inspections and provide targeted repairs or replacements to restore efficiency.

Unusual Noises: Banging, rattling, or whistling sounds often indicate loose joints, leaks, or damaged duct sections. Left unchecked, these issues waste energy and reduce airflow. CPI Service identifies the source and completes professional repairs to restore quiet, consistent operation.

Higher Energy Bills Higher utility costs without increased usage can point to leaky or poorly insulated ducts. Many San Francisco homes lose conditioned air through gaps and disconnections, forcing systems to run longer. CPI Service seals and replaces ducts to reduce energy waste and lower monthly bills.

At CPI Service, we are dedicated to helping San Francisco homeowners and businesses maintain efficient and reliable duct systems, ensuring comfort and energy savings year-round.
