Ductwork Replacement in Granada Hills
Even great insulation underperforms with failing ductwork — we replace, seal, and tune up duct systems so your HVAC moves the air it should.

Why Ductwork Replacement Matters in Granada Hills
A lot of Southern California homes have old, leaking, or disconnected ductwork that quietly wastes energy. Your home's comfort and efficiency are the result of multiple systems working together — and the ductwork is one of the biggest overlooked ones.
Your duct system is responsible for moving heated and cooled air throughout the house. If the ductwork is leaking, sagging, disconnected, poorly sealed, or deteriorated, then even a high-quality HVAC unit and good insulation can only do so much. We often get called out for attic insulation projects across the area and discover that the ductwork itself is one of the biggest issues in the attic.
Most Older Ductwork Is Near the End of Its Life
Most flexible duct systems in Southern California have an average lifespan of roughly 20 to 25 years, sometimes longer depending on attic conditions and installation quality. Over time the inner lining deteriorates, dust accumulates inside, seals weaken, connections loosen, insulation breaks down, and efficiency drops. Sometimes simply brushing against the ductwork causes it to fall apart because it was never secured properly in the first place.
Cooling the Attic Instead of the House
During Southern California summers, attics commonly reach 140 to 150 degrees, sometimes hotter. If the duct system is leaking, disconnected, or poorly insulated, you are essentially paying to cool the attic instead of the living space — which means higher bills, poor comfort, uneven airflow, and excess HVAC wear and tear.

Ductwork Services We Provide
Like-for-Like Replacement
Clean, efficient duct replacement — especially for single-story homes, second-story-only systems, and simple attic layouts — commonly using R6 and R8 ductwork.
Duct Sealing & Tune-Ups
When the existing system is still in decent shape, we seal leaks, re-strap sagging runs, reconnect disconnected ducts, and handle small tune-ups instead of a full replacement.
Proper Support & Strapping
We focus on straight airflow paths, proper support spacing, proper strapping, and proper tensioning — not the single zip tie we so often find holding ducts together.
Better Airflow & Comfort
Properly installed ductwork helps improve comfort, airflow, HVAC efficiency, and HVAC lifespan — addressing hot and cold spots throughout the house.
Indoor Air Quality
As older duct linings break down they contribute to dust, odors, and airborne particles. Replacement is often the better long-term fix once a system reaches a certain age.
Paired With Attic Insulation
We can often replace, seal, or tune up ductwork during attic insulation removal and replacement — doing both together avoids disturbing new insulation later and compounds the results.
Our Ductwork Process
A careful, attic-aware process that prioritizes the work that actually makes sense for your home.
Inspect the Attic & Duct System
We evaluate the condition of the ductwork and the overall HVAC system — looking for leaks, crushed sections, sagging runs, disconnected ducts, and deteriorated duct insulation.
Recommend the Right Order
Depending on the attic and HVAC system, there is sometimes a better order to perform upgrades. We help prioritize improvements in a way that makes sense long term — never to pressure unnecessary work.
Replace, Seal & Re-Strap
We perform like-for-like replacement or sealing, re-strapping, and reconnecting using high-quality HVAC tape, double-sealed connections, heavy-duty zip ties, and properly tensioned mechanical seals.
Verify Airflow & Comfort
We make sure the finished system delivers straight airflow paths and proper sealing so your HVAC equipment works less and your home stays evenly comfortable.

What Granada Hills Homeowners Say
"The new insulation and thorough duct cleaning has noticeably improved our comfort and temperature control. We highly recommend this company and thank Luke for his expertise and concern during the entire process."
"Luke told me that I would notice a decline in my electricity charges and that the house will stay cooler in the summer and warmer in the winter. The effect has been phenomenal. My AC used to kick in at 1:00 PM in the hot summer days and now it only come on at 4:00PM."
"Luke was easy to work with and educated me as insulation was not something I had any knowledge of. In the end, I got exactly what I needed at a very fair price. Luke and his crew were very professional and did great work at my home."
