LC Heating & Air provides duct cleaning in Temple City — 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 your home in Temple City has rooms that never seem to get comfortable, or if your energy bills seem high for the size of your house, the problem might not be your AC unit itself. It is often the ductwork hidden in your attic. At LC Heating & Air, I see many homes where 20% to 30% of the conditioned air is leaking into the attic space before it ever reaches your vents.
My name is Leo, and I run LC Heating & Air. I believe in being honest about what your system needs. I don't believe in selling you a new system if a targeted duct repair can fix your comfort issues. We use real diagnostic tools to find where your air is escaping and provide a clear, written estimate so you know exactly what you are paying for before we start.

Local HVAC considerations
Common Duct Issues in Temple City Homes
Temple City homes, especially the mid-century ranch houses and larger remodels I visit, often deal with extreme attic heat during our 95-100 degree summer days. When your ducts are leaky or the insulation has degraded, that attic heat gets pulled into your system or pushes your conditioned air out. I frequently find crushed flex duct from past attic work, disconnected joints at the plenum, and leaky boots where the duct meets the ceiling register.
These issues force your HVAC equipment to work much harder than it should. Because the system has to run longer to meet your thermostat setpoint, you end up with higher utility bills and premature wear on your blower motor and compressor. We focus on identifying these specific points of failure—like return air leaks or restricted airflow—to get your system performing the way it was designed.
Understanding Your Home's Duct System
Whether you are in a classic ranch house or a newer remodel, your duct system is the circulatory system of your home. In Temple City, we see a lot of attic-based duct systems. These are prone to specific problems: the flex duct can tear, the tape joints can dry out and fail over time, and the weight of insulation can cause ducts to sag or kink, restricting airflow.
When I inspect a home, I look at the whole picture—duct condition, electrical capacity, and how the outdoor condenser is positioned. If your ducts are undersized or poorly routed, even a brand-new AC unit won't cool your home properly. We check the basics first to ensure you aren't wasting money on repairs that won't solve the root cause.
Our Diagnostic Process
I don't just walk in and guess. We start by measuring airflow at your registers to see which rooms are underperforming. We then perform a duct pressurization test, often called a duct blaster test. This tells us exactly how much air is leaking out of your system.
Once we have the data, I walk you through what we found. If a repair is the right move, we outline the scope of work. If the ductwork is too far gone or the design is fundamentally flawed, I will tell you that, too. You deserve to know the facts before anyone touches your equipment.
Repair vs. Replacement: Making the Right Choice
A lot of contractors will push for a full duct replacement the moment they see a tear. That isn't always necessary. If your ductwork is mostly in good shape but has a few disconnected sections or leaky joints, a professional repair using mastic and proper sealing is often the best value.
However, if the ducts are undersized for your equipment, or if the material has deteriorated to the point where it is falling apart, replacement is the more practical choice. My goal is to provide a repair that lasts. If the system is worth saving, we will fix it. If the pattern points to replacement, I will explain why so you can make an informed decision for your home.
Cost Factors for Duct Services
Duct repair costs vary based on accessibility and the extent of the damage. Simple repairs to accessible sections are naturally more affordable than a full system sealing or re-routing. We offer a range of services, from targeted manual repairs to Aeroseal internal sealing for those hard-to-reach leaks in your attic.
We provide clear, written estimates for all our work. You won't find surprise fees here. We focus on providing a service that pays for itself through better comfort and reduced energy consumption over time.
Scheduling Your Service
We know that your time is valuable. When you call LC Heating & Air at (323) 970-3113, we work with you to find a time that fits your schedule. Because we are a local contractor, we understand the specific needs of Temple City homeowners.
Whether it is an attic access issue or a need for same-day service, we do our best to accommodate you. We arrive prepared with the tools to diagnose and, in many cases, repair your system on the spot.
Avoid These Common Duct Mistakes
One of the biggest mistakes I see is homeowners trying to use standard duct tape to seal leaks. Standard tape dries out and fails quickly in the heat of an attic. We use professional-grade mastic and foil tape designed to hold up to temperature fluctuations.
Another mistake is ignoring the return side of the system. If your return ducts are leaking, they are pulling in dust and attic air, which ruins your indoor air quality. Don't just focus on the supply vents; the return side is just as important for a healthy, efficient home.
Health, Safety, and Air Quality
Your ductwork doesn't just move air; it moves the air you breathe. When ducts leak in the attic, they pull in insulation fibers, dust, and potentially mold spores. By sealing those leaks, we aren't just saving you money on energy—we are keeping that attic air out of your living space.
We take safety seriously. As a licensed C-20 contractor, we ensure that all repairs meet safety standards, protecting both your equipment and your family's health.
Is Duct Repair Right for You?
If you are tired of hot spots in your home and high energy bills, it is time to look at your ducts. If your system is otherwise in good working order, duct repair is often the most cost-effective way to improve your comfort.
Call LC Heating & Air at (323) 970-3113. We will come out, perform a proper diagnostic, and give you an honest assessment. If we can fix it, we will. If you need something more, we will explain why.
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.

“AC wasn't cooling to setpoint even though it was running all day. LC found the condenser coils were completely clogged with cottonwood. Cleaned them on the spot and the system cooled my house 12 degrees in an hour.”
“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.”
