Ductwork Installation, Repair & Sealing in San Diego, CA
Leaky ducts waste up to 30% of conditioned air before it reaches living spaces. We inspect, test, seal, repair, and install ductwork systems that deliver what your equipment produces — to every room.
Stop Losing 30% of Your Air.
Leaky or poorly designed ductwork can waste up to 30% of the conditioned air a system produces, driving energy bills up and comfort levels down throughout the home. This means that even a perfectly functioning HVAC system can underperform significantly if the ductwork distributing that air is compromised.
Caspian Air inspects, seals, repairs, and installs ductwork systems for San Diego homes and commercial properties. Every ductwork project begins with a pressure test to identify exactly where losses are occurring before any work begins.
Properly functioning ducts are essential to any efficient heating and cooling system. Addressing ductwork problems often delivers an immediate improvement in both comfort and energy consumption — without any change to the HVAC equipment itself.

What This Service Delivers
Immediate Efficiency Gains
Sealing leaky ducts can reduce energy consumption by up to 30% — a measurable improvement that shows up on the very first utility bill.
Even Airflow Throughout
Well-designed and properly sealed ductwork delivers consistent airflow to every room — eliminating hot spots, cold corners, and pressure imbalances.
Improved Air Quality
Leaky ducts can pull dust, allergens, and contaminants from attics and crawl spaces into living areas. Sealed ducts keep the air clean.
Extended Equipment Life
When ducts are efficient, the HVAC system doesn't have to work as hard — reducing wear on motors, compressors, and heat exchangers.
Stop the leaks.Keep the comfort.Cut the bills.
The Process — Start to Finish
Duct Inspection
Visual inspection and pressure testing to identify all leaks, damage, and design issues before any work begins.
Written Diagnosis
We document all findings and explain the scope of work required — sealing, repair, insulation, or full replacement.
Sealing & Repair
Professional mastic sealing, duct repair, insulation wrapping, and connection reinforcement to eliminate all identified losses.
Post-Test Verification
After work is complete, we re-test the system to confirm the repairs have achieved the expected reduction in air loss.
Common Questions
Common signs include rooms that never reach the set temperature, high energy bills despite a functioning HVAC system, excessive dust accumulation, and uneven airflow throughout the home. A duct pressure test will give definitive measurements.
