Highland Park is a neighborhood with a lot of character, but its mix of historic Craftsman homes and mid-century remodels presents unique challenges for HVAC systems. Many homeowners here deal 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 furnace or AC unit itself, but the ductwork hidden in the attic or crawl space.
At LC Heating & Air, I believe in being straightforward. Before we talk about replacing equipment, we look at what you already have. If your ducts are leaking, you are paying to cool your attic instead of your living room. We use diagnostic tools to show you exactly where the air is escaping so you can make an informed decision about the best way to fix it.

Common Duct Issues in Highland Park Homes
In Highland Park, we see a lot of 'patchwork' HVAC systems. Because many homes here have been renovated over several decades, we often find ductwork that was modified during kitchen remodels or added onto without proper engineering. This leads to disconnected joints, crushed flex duct from attic traffic, and leaks at the plenums.
The climate here—with our hot summers and dusty environment—makes these leaks worse. When your return ducts leak in a hot attic, they pull in dust and insulation fibers, which then get blown directly into your living space. We focus on identifying these specific points of failure, whether it's a simple disconnected run or a need for more comprehensive sealing.
Working with Highland Park Architecture
Whether you are in a historic home near the Arroyo Seco or a newer infill build, the age of the structure matters. Older homes often lack the space for modern, high-efficiency ductwork, which can restrict airflow. We take the time to inspect your specific layout before recommending a repair.
If you are planning a renovation, it is the perfect time to look at your duct system. We often work with homeowners to ensure that any new HVAC installation is properly sized and routed to avoid the common pitfalls of older, inefficient systems.
Our Diagnostic Process
I don't believe in guessing. When I come out to your home, I start by measuring the airflow at your registers. If a room isn't getting enough air, we trace it back to the source.
We use duct pressurization testing—often called a duct blaster test—to quantify exactly how much air your system is losing. This gives us a clear number so you can see if the repair is worth the investment. We provide a written estimate for the work, so you know exactly what you are paying for before we start.
Repair vs. Replace: An Honest Look
One of the most common questions I get is, 'Should I just replace the whole system?' The answer depends on the condition of your equipment and the extent of the duct damage. If your furnace or AC is relatively new and the ductwork is mostly sound, a targeted repair is often the best path.
However, if the duct system is failing in multiple places or is undersized for your home, patching it might just be a temporary fix. I will be honest with you about whether a repair will actually solve your comfort issues or if you are better off saving that money toward a system upgrade.
Understanding Costs
Duct repair costs vary based on what we find. A simple reconnection of a flex duct is much different than sealing an entire system. We offer everything from manual sealing with mastic to Aeroseal for those hard-to-reach leaks in tight attics.
We provide transparent pricing based on the scope of the work. Our goal is to give you a system that works efficiently, not to sell you services you don't need.
Scheduling Your Service
We serve the entire 90042 area and surrounding neighborhoods. Because we are a local contractor, we understand the logistics of Highland Park streets and the importance of showing up on time.
When you call (323) 970-3113, we will discuss your symptoms and get a technician out to inspect your system. We check access, electrical, and duct condition to make sure we have a solid plan before we start any work.
Health and Safety
Leaky ducts are more than just an efficiency problem; they can affect your indoor air quality. If your return ducts are leaking in the attic, they are pulling in dust, insulation, and potential mold spores. Sealing these leaks helps keep your home's air cleaner.
We also ensure that all repairs meet safety standards, especially when working around gas-fired furnaces or existing electrical components in your attic.
Mistakes to avoid — Duct Repair in Highland Park
Oversized equipment, skipped maintenance, and DIY refrigerant or gas work are frequent duct repair mistakes we correct in Highland Park.
Closing too many registers or using the wrong filter MERV rating can starve airflow and shorten component life.
Is Duct Repair Right for You?
If you notice rooms that are always too hot or too cold, or if your energy bills are higher than they should be, it is worth having a professional look at your ducts. We don't believe in high-pressure sales; we believe in showing you the evidence.
If we find that your ducts are in good shape, we will tell you. If we find significant damage, we will show you where it is and explain how fixing it will improve your comfort and lower your energy usage. You deserve to know exactly what is happening inside your walls and ceilings.

What Highland Park customers say about duct repair
Verified reviews from homeowners in Highland Park and nearby neighborhoods who used our duct repair service.
“After the Eaton Fire, our ducts smelled like smoke. LC did a full cleaning — negative air pressure, rotary brushes, the works. Air quality in our home is completely different now. They were sensitive to what our neighborhood went through.”
“LC replaced our ancient wall furnace with a proper ducted system. They designed the ductwork from scratch for our bungalow. Took three days and the result is better than I expected — even heat throughout the whole house.”
“Had LC do a load calculation before choosing a new system. They recommended a smaller unit than the others — and they were right. Perfect comfort, lower bills, and the system doesn't short-cycle.”
