LC Heating & Air provides duct cleaning in Hollywood — including air duct cleaning, duct repair service, duct sealing, HVAC ductwork. Whether you need same-day service, a written estimate, or help deciding between repair and replacement, our licensed technicians handle every make and model.

Hollywood is our home territory. Operating out of our shop at 509 N Fairfax Ave, we have spent years working on the diverse housing stock that defines this area—from 1920s bungalows with original ductwork to modern remodels. We know that when your HVAC system isn't performing, it is usually a matter of comfort and cost. Our goal is to provide you with a clear, honest assessment of your duct system so you can make the right decision for your home.
The Department of Energy estimates that typical residential duct systems lose 20–30% of conditioned air through leaks. In Los Angeles, that means you are paying to cool your attic instead of your living room. We focus on finding those hidden leaks and providing practical repairs that make a measurable difference in your home's comfort.

Common Duct Issues in Hollywood Homes
Hollywood's housing stock ranges from historic homes to mid-century builds, and many have had HVAC systems retrofitted into spaces not originally designed for them. We frequently see undersized, poorly routed, or damaged ductwork. In the hillside areas like Beachwood Canyon and the Hollywood Hills, we often find crushed flex duct caused by limited attic access or complex routing that restricts airflow.
We also see the impact of our local climate. Between the heat of summer and the dust that settles in our attics, ductwork often suffers from failed mastic, torn inner liners, and disconnected joints. These issues force your equipment to work harder than necessary, leading to premature wear and higher energy bills.
Why Duct Condition Matters
Many homes in Hollywood were built before central air conditioning was standard. When systems were added later, the ductwork was often squeezed into tight attics or crawl spaces. This makes proper installation difficult and leads to common problems like disconnected sections at take-offs or leaky boots.
If your home has rooms that are consistently harder to heat or cool than others, it is often a sign of duct leakage rather than a failing AC unit. We check the entire system—from the return sizing to the register balance—to see if a targeted repair can solve the problem before recommending a full equipment replacement.
Our Diagnostic Process
We don't guess. We start by measuring airflow at your registers and performing a duct pressurization test. This allows us to quantify exactly how much air is leaking out of your system.
Once we have the data, we inspect the accessible ductwork to identify the source of the leaks—whether it is a torn flex duct, a failed joint, or a plenum issue. We then present you with a written plan and clear pricing. You will know exactly what we found and what it will take to fix it before we start any work.
Repair vs. Replacement
As an owner-operator, I believe in being honest about whether a repair is worth it. If your ductwork is in generally good shape but has specific leaks or disconnected runs, a repair is often the most practical solution. We can seal joints with mastic, reconnect flex duct, or replace damaged sections to restore performance.
However, if the ductwork is severely undersized, collapsed throughout the system, or made of materials that are falling apart, a repair might just be a temporary fix. In those cases, I will tell you straight that replacement is the better long-term investment. We want to provide a solution that lasts, not a quick fix that leads to a callback next season.
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 in an accessible attic is very different from sealing a complex system with widespread leaks. We provide written estimates so you aren't surprised by the final bill.
We offer options ranging from manual sealing with mastic to Aeroseal for inaccessible leaks. Every project includes post-repair testing to verify that the work actually improved your system's airflow.
Scheduling Service in Hollywood
We are located at 509 N Fairfax Ave, which allows us to reach most Hollywood neighborhoods—including Thai Town, Franklin Hills, and the Hollywood Dell—quickly. We understand that HVAC issues don't wait for a convenient time, so we offer same-day service options when possible.
Whether you are in a single-family home or manage a small multifamily building, we have the experience to navigate the unique access challenges of our local architecture. Give us a call at (323) 970-3113 to discuss your system.
Air Quality and Safety
Leaky ducts do more than waste energy; they can impact your indoor air quality. Return duct leaks in attics can pull insulation fibers, dust, and potential mold spores into your living space. Supply leaks can introduce attic air directly into your rooms.
Sealing these leaks is a practical way to keep your home cleaner and more comfortable. We prioritize safety and proper installation standards, ensuring that our repairs meet the requirements of CSLB #1073586.
Common Mistakes to Avoid
The biggest mistake we see is homeowners attempting to fix major duct issues with standard duct tape. Real duct repair requires professional-grade mastic and proper mechanical fasteners. Improperly sealed ducts will continue to leak, wasting your money and leaving your home uncomfortable.
Another mistake is ignoring the system as a whole. If you have weak airflow, it might be a duct issue, but it could also be a blower motor or filter problem. We look at the entire system to ensure we are fixing the root cause, not just the symptom.
Making the Right Choice
When you call LC Heating & Air, you are talking to a local contractor who values plain talk. We will inspect your system, show you the leaks, and explain whether a repair will get you the comfort you need.
If the system is worth repairing, we will tell you. If the pattern points to replacement, we will explain why. Our goal is to provide a solution that makes sense for your home and your budget.
