I'm Leo, owner of LC Heating & Air. I spend a lot of time in Malibu attics and crawl spaces, and I can tell you that most duct systems here are losing 20% to 30% of their conditioned air before it ever reaches your rooms. If you have rooms that just won't stay cool in the summer or warm in the winter, it isn't always the equipment's fault. Often, the air is simply leaking out into the attic or pulling in dusty, unconditioned air from outside.
My approach is straightforward: we don't guess. We use duct pressurization testing to find exactly where your system is losing air. Whether it's a disconnected flex duct, a crushed run, or leaky joints in your sheet metal, we provide a clear, written estimate for the repair. We serve Malibu with honest, practical solutions, not high-pressure sales.

Local HVAC considerations
Common Duct Issues in Malibu Homes
Malibu homes face unique challenges. Between the marine-layer humidity and the salt-air exposure, ductwork can deteriorate faster than in inland areas. We frequently see issues with failed mastic at supply plenums and torn inner liners on flex ducts that have been exposed to moisture or attic foot traffic.
Another pattern I see is crushed flex ducting. Because many coastal homes have tight attic spaces or complex architectural designs, ducts often get stepped on or pinched during other home maintenance. When a duct is crushed, it restricts airflow to specific rooms, making your HVAC system work much harder to push air through a bottleneck. We identify these restrictions during our diagnostic process and fix them to restore proper airflow.
Ductwork in Coastal Malibu Properties
Malibu's housing stock is diverse, ranging from older beach properties to renovated high-efficiency homes. Older homes often have leaky sheet metal ductwork that was never properly sealed, while newer renovations might have flex ducting that has been poorly installed or damaged during the construction process.
Regardless of the age of your home, the goal is the same: a sealed, efficient distribution system. We look at how your ducts are routed, how they handle the local climate, and whether the current insulation is sufficient to prevent heat gain in the attic. If your ducts are running through a hot attic, even a small leak can significantly impact your indoor comfort.
Our Diagnostic Process
We don't just look at the registers and guess. We start by measuring airflow at each register to see which rooms are underperforming. Then, we perform a duct pressurization test. This is the only way to get a real number on how much leakage you actually have.
Once we have the data, we inspect the accessible sections of your ductwork. We check for disconnected joints, torn insulation, and damaged boots. We then sit down with you to explain what we found and provide a written estimate. You'll know exactly what we're fixing and why before we start.
Repair or Replace: Making the Right Choice
A common question I get is whether to repair or replace the entire duct system. If the ductwork is structurally sound but has leaks, tears, or disconnected sections, a repair is usually the most practical and cost-effective choice. We can seal these leaks with mastic or replace damaged sections of flex duct.
However, if the ductwork is undersized for your equipment, made of obsolete materials, or so severely damaged that it's falling apart, replacement might be the better long-term investment. I will always tell you if a repair is enough. We aren't here to sell you a new system if a simple, honest repair will get your home comfortable again.
Understanding Costs
Duct repair costs vary based on the accessibility of the ducts and the extent of the damage. A simple reconnection of a flex duct is much less expensive than a comprehensive sealing project. We offer transparent pricing for everything from basic inspections to full-system Aeroseal applications.
We focus on providing value. By sealing your ducts, you reduce the runtime of your HVAC equipment, which lowers your monthly energy bills and reduces wear and tear on your blower motor and compressor. It's an investment that pays for itself in comfort and efficiency.
Access and Professional Service
Malibu homes often have unique access challenges, including roof-mounted condensers and tight attic spaces. We plan our work around these constraints, ensuring that our drain routing and equipment placement handle the coastal conditions properly. We respect your home and your time, and we always clean up after ourselves.
If you're noticing uneven temperatures or high utility bills, give us a call at (323) 970-3113. We'll schedule a time to come out, inspect your system, and give you an honest assessment of what's going on.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to patch leaks with standard duct tape. Duct tape dries out and fails quickly, especially in the heat of an attic. We use professional-grade mastic and foil tape designed for the job. Another mistake is ignoring the 'whistling' sounds coming from your ceiling; that's almost always a sign of a significant air leak that is wasting your money.
Don't assume that a 'dusty house' is just normal. If you see dust accumulating around your registers, your return ducts are likely pulling in attic air. That's not just an efficiency issue; it's an air quality issue that we can fix.
Health and Safety Considerations
Your HVAC system is the lungs of your home. When your return ducts leak in the attic, they pull in insulation fibers, dust, and potential mold spores, distributing them throughout your living space. Sealing these leaks is one of the most effective ways to improve your indoor air quality.
We also ensure that all repairs are done safely, keeping your equipment running within its designed parameters. We are fully licensed (CSLB #1073586) and insured, so you can have peace of mind knowing the work is being done by a professional who understands the local building requirements.

What Malibu customers say about duct repair
Verified reviews from homeowners in Malibu and nearby neighborhoods who used our duct repair service.
“Had LC install a Daikin mini split in our 1940s bungalow that never had AC. The work was clean, the unit is incredibly quiet, and our bedroom finally stays cool in summer. Highly recommend.”
“We converted our garage into an ADU and needed HVAC. LC installed a Mitsubishi single-zone mini split — permits, electrical, everything. The unit is so quiet you can barely hear it running. Our tenant loves it.”
“Got a 3-zone Daikin system for our craftsman home — bedrooms upstairs, living room downstairs. Each room has its own temperature control and the monthly electric bill is actually lower than our old window units combined.”
