If your Santa Monica home has rooms that never seem to get comfortable, the problem is often hiding in your ductwork. At LC Heating & Air, we specialize in diagnosing and sealing leaky, crushed, or disconnected ducts to restore proper airflow and efficiency.

I’m Leo, the owner of LC Heating & Air. I’ve spent enough time in Santa Monica attics to know that most comfort issues aren't caused by a broken AC unit, but by the ductwork that carries the air. When your ducts leak, you’re paying to cool your attic or crawl space instead of your living room. It’s a waste of money and it puts unnecessary strain on your equipment.
My approach is straightforward: I don't believe in guessing. We use diagnostic tools to measure exactly how much air you're losing and where those leaks are located. Whether it’s a simple reconnection of a flex duct or a more complex sealing job, I’ll give you an honest assessment of what needs to be done and what it will cost before we start any work.

Local HVAC considerations
Common Duct Issues in Santa Monica Homes
Santa Monica homes face unique challenges, especially with our marine-layer humidity and salt-air environment. We frequently see duct systems suffering from degraded insulation and failed mastic at joints due to the constant moisture. In older beach properties, we often find original ductwork that wasn't sized correctly for modern high-efficiency systems, leading to restricted airflow.
Another common issue is crushed or kinked flex duct. Because space is often tight in coastal homes, ducts get stepped on or compressed during other home repairs, which chokes off the air supply to specific rooms. We also see 'leaky boots'—where the connection between the duct and the floor or ceiling register has pulled away—allowing dust and attic air to enter your living space.
Understanding Your Home's Ductwork
Whether you live in a classic beach bungalow or a renovated condo, your duct system is the lungs of your home. In Santa Monica, we deal with a mix of older sheet metal systems and modern flex ducting. Sheet metal can rust or develop gaps at the seams over time, while flex duct can tear or lose its shape.
If you notice whistling sounds or dust accumulating around your registers, it’s a sign that your ducts are pulling in air from unconditioned spaces. We look at the entire run—from the return air intake to the supply registers—to ensure the system is balanced and the air is actually reaching the rooms where you spend your time.
How We Diagnose Your System
We don't just look at the ducts and guess. We start by measuring the airflow at each register to see which rooms are underperforming. Then, we perform a duct pressurization test, also known as a duct blaster test. This tells us exactly how much air is leaking out of the system.
Once we have the numbers, we inspect the accessible sections of your ductwork. We look for disconnected joints, torn inner liners, and areas where insulation has failed. By the time we finish the diagnostic, you'll know exactly what the problem is and we’ll have a plan to fix it.
Repair or Replace?
A lot of companies will try to sell you a full duct replacement the moment they see a leak. That’s not how I work. If your ducts are in decent shape but have a few disconnected sections or small leaks, a targeted repair is often all you need to restore comfort.
However, if the ductwork is severely undersized, falling apart, or made of outdated materials that are beyond saving, I will tell you that replacement is the better long-term investment. My goal is to provide a solution that makes sense for your home and your budget, not to push for a sale you don't need.
What to Expect Regarding Costs
Duct repair costs depend on the scope of the work. A simple inspection and minor sealing might be straightforward, while a full system sealing or repair of damaged runs takes more time and materials. We provide a clear, written estimate before we touch your equipment.
Factors that influence the price include the accessibility of the ducts in your attic or crawl space and whether we need to use specialized methods like Aeroseal for leaks that are hidden inside walls or ceilings. We focus on providing value by ensuring the repair is done correctly the first time, preventing future callbacks.
Scheduling Your Service
We know your time is valuable. When you call LC Heating & Air at (323) 970-3113, we’ll work with you to find a time that fits your schedule. Because we are a local contractor, we understand the logistics of Santa Monica, including the need for proper roof access planning and ensuring that drain routing handles our damp coastal conditions.
We arrive prepared to diagnose and, in many cases, perform repairs on the same visit. If the job requires more extensive work, we’ll schedule a follow-up that works for you.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to patch leaks with standard duct tape. It doesn't hold up, especially in the heat of an attic. You need professional-grade mastic or foil tape designed for HVAC systems.
Another mistake is ignoring the return side of the system. People focus on the supply registers, but if your return ducts are leaking, you’re pulling dust, insulation fibers, and attic air directly into your HVAC system. This hurts your air quality and forces your system to work much harder than it should.
Health and Safety Considerations
Your indoor air quality is directly tied to your ductwork. Leaky ducts in an attic can pull in mold spores, dust, and insulation particles, which then get blown into your living areas. Sealing these leaks isn't just about comfort; it’s about breathing cleaner air.
We also ensure that all repairs are done safely, keeping in mind the structural integrity of your home and the safety of your HVAC equipment. As a CSLB-licensed contractor (License #1073586), we follow all safety protocols to ensure your system runs efficiently and safely.
Is Duct Repair Right for You?
If you’re tired of uneven temperatures or high energy bills, it’s time to look at your ducts. If your system is otherwise in good working order, duct repair is often the most cost-effective way to improve your home's comfort.
Call LC Heating & Air at (323) 970-3113. We’ll come out, inspect your system, and give you an honest answer about whether a repair will solve your problems or if you need to consider other options. We’re here to help, not to sell.

What Santa Monica customers say about duct repair
Verified reviews from homeowners in Santa Monica 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.”
