If you live in Sunland, you know how much the local climate—with its specific sun exposure and hillside topography—can affect your home's comfort. Many homeowners here struggle with rooms that never seem to get enough air, or energy bills that climb too high during the summer. Often, the culprit isn't the HVAC unit itself, but the ductwork hidden in your attic or crawl space.
I'm Leo, owner of LC Heating & Air. I’ve seen firsthand how leaky, crushed, or poorly installed ducts force your system to work twice as hard to keep your home comfortable. We don't believe in guessing; we use diagnostic testing to find exactly where your system is losing air and provide a clear, honest plan to fix it.

Local HVAC considerations
Common Duct Issues in Sunland Hillside Homes
Sunland’s unique housing stock, including hillside homes and canyon properties, presents specific challenges for ductwork. We frequently find ducts that have been crushed by foot traffic in tight attic spaces or disconnected due to the settling of older custom homes. Because of the elevation changes and varied sun exposure, even a small leak in a supply run can make a specific room feel significantly hotter than the rest of the house.
We also see issues with 'return' duct leaks. When a return duct leaks in a hot attic, it pulls in unconditioned, dusty air and pushes it directly into your living space. This doesn't just hurt your energy efficiency; it impacts your indoor air quality. Whether it’s a torn flex duct liner or a failed mastic joint, we identify the root cause so you aren't just putting a bandage on a larger problem.
Navigating Tight Access and Custom Layouts
Working in Sunland means dealing with tight-access mechanical areas and complex line-set routing. Many older homes in this area weren't designed with modern HVAC service clearances in mind. When we perform a duct inspection, we account for these physical constraints.
We don't just look at the equipment; we look at how the ductwork is routed through your home's structure. If your ducts are inaccessible, we don't force a solution that won't work. We discuss options like Aeroseal for internal sealing or targeted manual repairs where access allows, ensuring the job is done right without damaging your property.
Our Diagnostic Process: No Guesswork
Before we touch a single piece of ductwork, we perform a thorough diagnostic. We measure airflow at your registers to see exactly what is reaching your rooms versus what the system is producing. We also use duct pressurization testing—often called a duct blaster test—to quantify exactly how much air is leaking out of your system.
This data allows us to give you a written estimate that makes sense. You’ll know exactly what we’re fixing and why. We believe in showing you the evidence, so you can make an informed decision about whether a repair will solve your comfort issues or if the system requires a different approach.
Repair vs. Replacement: An Honest Assessment
One of the most common questions I get is, 'Leo, should I just replace the whole system?' My answer is always the same: it depends on the condition of the equipment and the extent of the duct damage. If your ducts have minor leaks or a few disconnected sections, a repair is often the most cost-effective way to restore comfort.
However, if the ductwork is severely undersized, crushed beyond repair, or if the HVAC equipment is nearing the end of its life, we will tell you. We don't push for replacement if a repair will do the job, but we also won't suggest a repair if we know it’s just throwing money at a system that is fundamentally failing. We provide the facts so you can decide what’s best for your budget.
Understanding the Costs
We provide clear, upfront pricing for our services. A basic duct inspection typically ranges from $125 to $200. If we find specific leaks, targeted repairs usually cost between $200 and $600, depending on how hard it is to reach the area. For more comprehensive work, like full-system sealing, costs can range from $800 to $3,000.
We always provide a written estimate before we start. We don't believe in hidden fees or surprise costs. Our goal is to ensure that the investment you make in your ductwork provides a measurable return in energy savings and comfort.
Air Quality and Safety
Duct leaks are a major contributor to poor indoor air quality. When your return ducts are leaky, they pull in dust, insulation fibers, and allergens from your attic. This is particularly relevant in Sunland, where attic temperatures can get extreme.
By sealing these leaks, we stop the system from distributing attic air throughout your home. This is especially important for households with allergy sufferers or those concerned about the cleanliness of their air. We treat your home’s air quality with the same care we would our own.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to fix duct leaks with standard duct tape. Real duct tape—the kind you buy at the hardware store—doesn't hold up to the temperature swings in a Sunland attic. It dries out, cracks, and falls off within a season.
We use professional-grade mastic and mechanical fasteners to ensure the repair lasts. Another mistake is assuming that 'more air' is always better. If you seal ducts without checking the system's static pressure, you can actually damage your blower motor. We always check the balance of the system to ensure our repairs improve performance without putting undue stress on your equipment.
Scheduling Your Service
We know your time is valuable. Because we are a local contractor, we can often accommodate scheduling needs that larger companies can't. Whether you need a diagnostic visit or a full-day repair, we coordinate with you to ensure we have the necessary access to your attic or crawl space.
We are fully licensed (CSLB #1073586) and insured. When we arrive at your home in Sunland, we come prepared to get the job done right, with the tools and materials needed to address the specific layout of your property.

What Sunland customers say about duct repair
Verified reviews from homeowners in Sunland and nearby neighborhoods who used our duct repair service.
“Our AC stopped working during a heat wave and LC had a technician here within two hours. He diagnosed a bad capacitor, had the part on his truck, and fixed it on the spot. Fair price, no upsell. Will use again.”
“Called on a Saturday because AC was blowing warm air. LC answered, sent someone the same afternoon. They found and fixed a refrigerant leak. Professional and reasonably priced.”
“Woke up to no AC at 6am. LC was at my door by 9am. Frozen evaporator coil — they explained exactly why it happened (dirty filter + low airflow) and fixed it same visit. Very professional.”
