Expert Duct Work Inspection, Repair, and Installation
Serving Gilroy & Surrounding Areas
Comprehensive Duct Work Services
From assessment to airflow optimization
American Coast Heating and Cooling provides end-to-end duct work solutions for homes and businesses, including detailed inspections, design corrections, repairs, sealing, insulation, replacements, and new installations. With 16+ years of experience, our trained technicians optimize airflow, reduce system strain, and ensure your HVAC distributes conditioned air efficiently.
We identify and correct issues such as undersized runs, kinks, disconnections, high static pressure, and leakage that cause uneven rooms, noise, and higher bills. Using proper materials and methods—mastic sealing, UL-181 approved tape, correctly sized rigid or flexible duct, and balanced layouts—we restore comfort while improving efficiency and reliability.
Comfort, efficiency, and air quality
Well-designed duct work is the backbone of HVAC performance. Air leaks waste energy, poor insulation loses or gains heat, and improper sizing forces equipment to short cycle or work overtime. Tight, well-insulated runs protect indoor air quality by reducing dust infiltration and help your system achieve its rated efficiency.
Common warning signs include rooms that never reach set temperature, whistling or rattling, visible gaps at joints, excessive dust, musty odors, frequent cycling, or rising utility costs. Our team verifies root causes with pressure and airflow measurements, duct leakage testing, and visual inspections so repairs address the problem—not just the symptom.
Transparent assessments and tailored solutions
Our process starts with a thorough assessment: accessibility and safety review, condition check of supply and return trunks, branch runs, plenums, boots, and registers, followed by static pressure and airflow readings. You receive clear findings with photos and a prioritized plan that fits your goals and budget.
We perform targeted repairs and upgrades such as resealing joints with mastic, replacing damaged sections, straightening crushed flex, adding proper supports and hangers, insulating to current standards, resizing or adding returns, balancing dampers, and refining transitions for smoother airflow. Where replacement makes more sense, we fabricate and install new, code-compliant runs that match system capacity.
Need fast help? We offer emergency services: leak check, repair, service, HVAC preventive maintenance. From urgent duct leaks to routine tune-ups that prevent future breakdowns, American Coast Heating and Cooling delivers responsive scheduling, quality workmanship, and lasting results.
