Quick answer

LC Heating & Air provides professional duct diagnostics and repair to solve uneven temperatures and high energy bills in Beverly Glen homes.

If you live in Beverly Glen, you know that our canyon climate can be tricky. Between the marine-layer humidity and the heat that builds up in the Santa Monica Mountains, your HVAC system works hard to keep your home comfortable. Often, the problem isn't the equipment itself, but the ductwork that carries the air. If your ducts are leaking, you are paying to cool your attic instead of your living room.

I'm Leo, owner of LC Heating & Air. I’ve spent years working on coastal homes and canyon properties, and I’ve seen how quickly ductwork can deteriorate due to moisture and shifting attic conditions. My approach is simple: I don't guess. We use real measurements to find where your system is losing air and provide a clear, honest plan to fix it.

Common Duct Issues in Beverly Glen

In Beverly Glen, we deal with specific environmental factors that impact ductwork. The marine-layer moisture can accelerate the degradation of older materials, while the canyon terrain often means homes have complex, tight attic spaces. We frequently find crushed flex ductwork from past maintenance traffic, disconnected joints at the plenum, and leaky register boots that allow attic dust to enter your living space.

These leaks don't just waste energy; they cause comfort swings. If you have rooms that are always hotter than others, it’s usually because the airflow is escaping before it ever reaches the vent. We focus on identifying these specific points of failure—whether it's a torn inner liner or a poorly sealed joint—to restore the balance of your home's air distribution.

Ductwork in Canyon Homes

Beverly Glen features a mix of older beach-style properties and newer, high-efficiency renovations. Older homes often have sheet metal ductwork that has lost its seal over time, while newer homes might rely on flex duct that is susceptible to kinking or tearing if not installed with enough clearance.

Because our homes are often nestled in the mountains, access is a major factor. We plan our repairs around the specific layout of your attic or crawl space, ensuring that we can reach the source of the leak without causing further damage to your home's structure or insulation.

How We Diagnose Your System

We don't just look at the ducts and guess. We use a systematic approach to find the leaks. First, we measure the airflow at your registers to see if it matches what your system is designed to deliver. Then, we perform a duct pressurization test (duct blaster test). This allows us to quantify exactly how much air is leaking out of your system.

Once we have the data, we walk you through the findings. We show you exactly where the leaks are and explain whether a targeted repair is the right move or if the system requires more comprehensive sealing. You get a written estimate before we start any work, so you know exactly what you're paying for.

Repair or Replace?

A common question I get is whether it's worth repairing old ducts or if they should be replaced entirely. If the ductwork is structurally sound but has leaks at the joints or minor tears, a repair is usually the most practical and cost-effective choice. We can seal these leaks with mastic or replace small sections of damaged flex duct.

However, if the ducts are severely undersized, collapsed in multiple areas, or made of outdated materials that are falling apart, a full replacement might be the better long-term investment. I’ll always give you the honest truth. If a repair will get you the comfort you need, that’s what I’ll recommend. If the system is too far gone, I’ll explain why replacement is the safer, more efficient path.

Understanding the Costs

Duct repair costs vary based on the extent of the damage and how easily we can access the ducts. A simple reconnection of a loose section is a straightforward job, while sealing a full system or using Aeroseal technology for hidden leaks requires more time and specialized equipment.

We provide transparent pricing ranging from $125 for a basic inspection to $5,000 for extensive repairs or replacements. Because we are a local contractor, we don't have the overhead of large franchises, which keeps our focus on the quality of the repair rather than sales quotas.

Scheduling Your Service

We know that living in the canyon can make scheduling difficult, especially with narrow roads and limited access. We coordinate with you to ensure we have the time and space needed to perform a thorough inspection and repair. Whether you need a quick diagnostic or a full day of duct sealing, we prioritize clear communication so you aren't left waiting.

Give us a call at (323) 970-3113 to discuss your system. We serve the Beverly Glen area and are familiar with the unique logistical challenges of our local neighborhoods.

Mistakes to Avoid

The biggest mistake I see is homeowners trying to fix duct leaks with standard duct tape. It doesn't hold up in the heat of an attic and will fail within a few months. Proper repair requires mastic sealant or specialized foil tape that can handle the temperature fluctuations in your attic.

Another mistake is ignoring the return side of the system. Many people focus only on the supply ducts, but if your return ducts are leaking, you are pulling in dust, insulation fibers, and attic air, which ruins your indoor air quality. We check both sides of the system to ensure the entire loop is airtight.

Health and Safety First

Your HVAC system is the lungs of your home. When ducts leak in an attic, they act like a vacuum, pulling in whatever is up there—dust, debris, and potential mold spores—and distributing it throughout your living space. Sealing your ducts is one of the most effective ways to improve the air quality in your home.

We also ensure that all repairs are done safely, following CSLB standards. We don't cut corners that would compromise the safety of your equipment or your family's health. We are licensed (CSLB #1073586) and insured, so you can have peace of mind while we work.

Is Duct Repair Right for You?

If you are noticing high energy bills, uneven temperatures, or excessive dust, it's time to look at your ducts. Duct repair is a high-value improvement because it addresses the root cause of many comfort issues rather than just masking the symptoms with a new thermostat or a bigger AC unit.

If you're ready to get your system running the way it was designed to, reach out to LC Heating & Air. We’ll come out, inspect your system, and give you an honest assessment of what needs to be done. No pressure, just practical advice.

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.

Frequently asked questions

Duct Repair in Beverly Glen — common questions

How do I know if my ducts are leaking?
The clearest symptom is rooms that are consistently harder to heat or cool than others, combined with high energy bills. Dusty supply registers can indicate return duct leaks drawing unconditioned attic air. A professional duct pressurization test (duct blaster test) quantifies exactly how much leakage exists in your system.
How much does duct repair cost in Los Angeles?
Targeted repairs to specific disconnected sections or obvious damage: $200–$600 depending on location and accessibility. Comprehensive duct sealing on a system with widespread leakage: $800–$2,000. Aeroseal internal duct sealing for hard-to-access leaks: $1,500–$3,000 for a typical home. We provide a written estimate after the diagnostic.
Can I repair ducts myself?
Accessible flex duct reconnections are DIY-possible using proper foil tape and mastic. However, most significant duct leakage occurs at joints, plenums, and take-offs in attic spaces that are difficult to access and inspect without experience. Improper repairs can make things worse. Professional diagnosis and repair ensures the right problems are fixed correctly.
What is Aeroseal duct sealing?
Aeroseal is a patented process that seals ductwork from the inside. The system pressurizes the duct network and injects a mist of adhesive polymer particles that stick to and seal leaks as air flows through them. It's particularly effective for leaks in inaccessible sections of ductwork. We offer Aeroseal for systems where manual repair can't reach all the leaks.
How long does duct repair take?
Targeted repairs to specific accessible damage: 2–4 hours. Comprehensive manual sealing of a full duct system: a full day. Aeroseal sealing: typically 4–6 hours for the sealing process plus setup and testing time.
Will duct repair help my HVAC system last longer?
Yes. Leaky ducts force your HVAC equipment to run longer cycles to meet the thermostat setpoint. More runtime means more wear on the compressor, blower motor, and heat exchanger. Sealed ducts reduce runtime, lower the equipment duty cycle, and extend component life.
