LC Heating & Air provides duct cleaning in El Segundo — 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.

If you have rooms that never seem to get comfortable, or if your energy bills are higher than they should be, the problem often isn't your air conditioner itself—it's the ductwork delivering the air. In El Segundo, we see a lot of homes where the distribution system is leaking conditioned air into attics or crawl spaces, forcing the equipment to work overtime.
I'm Leo, owner of LC Heating & Air. My approach is simple: I don't believe in guessing. We use professional diagnostic tools to measure exactly how much air your system is losing. If a repair makes sense, we fix it right. If the system is beyond help, I’ll tell you that too. We are licensed (CSLB #1073586) and focused on getting your home's airflow back to where it needs to be.

Common Duct Issues in El Segundo Homes
El Segundo's coastal environment presents specific challenges for ductwork. Between the marine-layer humidity and the age of many local homes, we frequently find disconnected duct sections, crushed flex duct, and failed mastic at supply plenums. Because of the salt air and moisture, older sheet metal joints can deteriorate faster, leading to significant air loss.
We also see issues related to attic access and space constraints. In many coastal homes, ducts are tucked into tight, hard-to-reach areas. When these ducts get crushed by foot traffic during other home repairs or simply sag over time, airflow to your registers drops significantly. We look for these patterns during our diagnostic process to ensure we aren't just patching a symptom, but fixing the actual leak.
Understanding Your Home's Airflow
Whether you live in an older beach property or a renovated home with a high-efficiency system, the physics of your ductwork remains the same. If your ducts are leaking, your HVAC system is essentially cooling your attic. This is a common issue in El Segundo, where the marine layer and temperature swings make consistent comfort a priority.
We focus on return sizing, duct leakage, and register balance. If your return ducts are undersized, the system struggles to pull enough air, which puts extra strain on your blower motor. We check these factors to ensure that when we perform a repair, the entire system functions as a balanced unit.
Our Diagnostic Process
I don't start any work until we know exactly what is wrong. We begin by measuring airflow at your registers to see which rooms are underperforming. Then, we perform a duct pressurization test—also known as a duct blaster test—to quantify exactly how much air is leaking out of your system.
This data gives us a clear picture. We identify the specific leaks, whether they are at the joints, the plenums, or in the flex duct runs. We then present a written estimate that outlines the scope of the repair. You will know exactly what we are doing and why before we start.
Repair vs. Replacement: Making the Right Call
One of the most common questions I get is whether a duct system is worth repairing or if it needs to be replaced. If the ductwork is structurally sound but has separated joints or small tears, a targeted repair is usually the best path. We can seal these leaks with mastic or replace small sections of damaged flex duct.
However, if the ducts are severely undersized, collapsing throughout the home, or made of outdated materials that are falling apart, patching them is just a temporary fix. In those cases, I will be honest with you that replacement is the better long-term investment. My goal is to provide a solution that lasts, not one that requires a callback in six months.
What to Expect Regarding Costs
Duct repair costs vary based on the extent of the damage and how difficult it is to access the ducts. A simple reconnection of a loose duct is a much smaller job than a full system sealing. We provide transparent pricing for all our services, ranging from basic inspections to comprehensive sealing.
We also offer Aeroseal duct sealing for systems where manual repair isn't feasible. This process seals leaks from the inside, which is particularly effective for inaccessible areas. We will discuss the best method for your specific home during our initial assessment.
Air Quality and Safety
Leaky ducts aren't just an efficiency problem; they are an air quality issue. When your return ducts leak in an attic, they pull in insulation fibers, dust, and potentially mold spores, distributing them throughout your living space. Sealing these leaks prevents that attic air from entering your home.
Furthermore, we ensure that all repairs are done safely. We check for proper drain routing and ensure that our work doesn't interfere with the equipment's safety features. We take the time to do it right because your family's health and the safety of your home are the most important parts of the job.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to fix ducts with standard duct tape. It doesn't hold up, especially in the temperature fluctuations of an attic. Proper duct repair requires mastic or specialized foil tape that can handle the expansion and contraction of the system.
Another mistake is ignoring the airflow balance. Just sealing a leak might increase pressure in one area while causing issues elsewhere if the system wasn't designed for that change. We look at the system as a whole to ensure that our repairs improve your comfort rather than creating new problems.

What El Segundo customers say about duct repair
Verified reviews from homeowners in El Segundo 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.”
