I'm Leo, owner of LC Heating & Air. I spend a lot of time in attics and crawl spaces across Cypress Park, and I can tell you that most homeowners don't realize how much their ductwork affects their comfort. If your AC is running constantly but certain rooms still feel like a sauna, the problem usually isn't the equipment—it's the delivery system.
Leaky ducts are the hidden culprit behind high energy bills and uneven temperatures. When your ducts have holes, gaps, or disconnected sections, you are paying to cool your attic instead of your living room. My team and I focus on finding those leaks, testing the system, and providing honest, practical repairs that get your air where it actually belongs.

Local HVAC considerations
The Hidden Cost of Leaky Ducts in Cypress Park
The Department of Energy estimates that typical residential duct systems lose 20–30% of conditioned air through leaks before it reaches the living space. In Los Angeles, where AC runs heavily from May through October, that means you're paying to cool your attic rather than your living room every summer. Duct repair is one of the highest-return HVAC improvements a Cypress Park homeowner can make.
In our neighborhood, we see a mix of older homes and recent remodels. Older homes often have deteriorating joints or original sheet metal that has lost its seal. Newer remodels sometimes have flex duct that was crushed or kinked during construction, which chokes off airflow. We identify these issues through airflow measurements and duct pressurization testing to ensure we aren't just guessing.
Cypress Park Home Context
Cypress Park has a unique mix of single-family homes, duplexes, and smaller multifamily buildings. Because many of these properties have been updated over the decades, we often find 'Frankenstein' duct systems—a mix of old metal trunks and newer flex duct that don't always play nice together.
When we inspect your system, we look at how the ductwork is routed through your specific floor plan. We check for crushed flex runs, leaky boots at the registers, and damaged insulation. In this climate, attic heat gain is a major factor; if your ducts are leaking in a hot attic, that air is being heated up before it ever reaches your vents.
Our Diagnostic Process
I don't believe in guessing. Before we touch a single piece of ductwork, we perform a thorough diagnostic. We measure airflow at your registers to see which rooms are actually getting the air they need. We also use duct pressurization testing to quantify exactly how much leakage exists.
This process gives us a clear picture of whether a repair will solve your comfort issues or if the duct system is beyond saving. We provide a written estimate based on these findings so you know exactly what you are paying for before we start.
Repair vs. Replacement: The Honest Truth
A lot of companies will push for a full duct replacement the moment they see a tear. That isn't how I operate. If your ducts are fundamentally sound but have a few disconnected joints or small leaks, a targeted repair is the right choice. We can seal those gaps with mastic and reconnect loose sections to restore performance.
However, if the ductwork is severely undersized, collapsing, or made of outdated materials that are falling apart, I will tell you that replacement is the better long-term investment. My goal is to give you a system that works, not just a temporary patch that will fail again in six months.
Understanding Your Costs
Duct repair costs vary based on accessibility and the extent of the damage. A simple reconnection of a loose flex duct is a different job than sealing an entire system that has never been maintained. We offer transparent pricing for everything from basic inspections to comprehensive Aeroseal treatments.
We consider factors like how difficult it is to reach your ducts in the attic or crawl space, the type of insulation present, and the total length of the duct runs. You will always have a written estimate in hand before we begin any work.
Access and Scheduling
Cypress Park homes often have tight attic access or unique layouts that make HVAC work challenging. We account for this during our initial visit. We check electrical, duct condition, and equipment placement to ensure we can actually perform the repair safely and effectively.
We know your time is valuable. We aim to provide clear communication regarding our arrival and the time required for the job. Whether it's a 2-hour targeted repair or a full-day sealing project, we make sure you know what to expect.
Common Duct Mistakes
The biggest mistake I see is homeowners trying to fix ducts with standard duct tape. It doesn't hold up in the heat of a Los Angeles attic. It dries out, cracks, and falls off, leaving you with the same problem you started with. We use professional-grade mastic and mechanical fasteners that are built to last.
Another mistake is ignoring the return side of the system. If your return ducts are leaking, they are pulling in dust, insulation fibers, and attic air, which then gets blown directly into your living space. Sealing the return side is just as important as sealing the supply side for your indoor air quality.
Health and Safety
Your health is tied to your HVAC system. Leaky return ducts can pull contaminants from your attic or crawl space into your home. By properly sealing your ductwork, we prevent that unconditioned, dusty air from circulating through your living areas.
As a licensed contractor (CSLB #1073586), I take safety seriously. We ensure all repairs meet current standards, and we never cut corners that could compromise the safety of your home or the efficiency of your equipment.
Is Duct Repair Right for You?
If you notice rooms that are consistently uncomfortable, high energy bills, or excessive dust, it is time to look at your ducts. We will come out, inspect the system, and give you an honest assessment of whether a repair will fix the issue.
If the system is worth repairing, we will tell you. If the pattern points to replacement, we will explain why. We want you to make an informed decision that makes sense for your home and your budget.
How the visit works
We measure airflow at registers, inspect accessible ductwork, and perform duct pressurization testing to quantify leakage.
We identify the specific leaks and damage and present a repair scope with written pricing before any work begins.
We access damaged sections and seal with mastic, reconnect disconnected flex duct, and repair torn inner liners.
We re-test duct leakage after repair and measure airflow at registers to confirm improvement.
Cost factors we review before quoting
- • Accessibility of ductwork in attics or crawl spaces
- • Total linear footage of ductwork requiring repair
- • Type of duct material (flex vs. sheet metal)

“LC replaced our entire HVAC system — new Carrier condenser, furnace, and coil. Leo walked us through every option without pressure. The install team was professional and clean. System runs perfectly and our electricity bill dropped about 30%.”
“Called LC because our CO detector went off. Their technician found a crack in the heat exchanger and immediately shut down the furnace. He explained the safety issue clearly, provided a replacement estimate, and didn't try to scare us — just facts.”
