I'm Leo, owner of LC Heating & Air. I spend a lot of time in Glassell Park, and I see the same thing in many of our local homes: a perfectly good HVAC unit struggling because the ductwork is leaking, crushed, or poorly designed. If your AC is running constantly but your living room stays warm, the problem usually isn't the unit—it's the delivery system.

Practical, honest repair vs. replacement advice
Common Duct Issues in Glassell Park
Glassell Park's hillside terrain and mixed housing stock—from 1920s bungalows to mid-century hillside homes—create unique duct challenges. We frequently find disconnected flex duct sections at joints, crushed ducts caused by attic foot traffic, and failed mastic at supply plenums. In many older homes, the original ductwork was never sized for modern, high-efficiency cooling, leading to weak airflow in specific rooms.
Because many homes here are built on slopes, we often see complex duct routing that is difficult to access. If a duct is hard to reach, it's often ignored during routine maintenance. We specialize in navigating these tight spaces to identify leaks that are costing you money every time your thermostat clicks on.
HVAC for Glassell Park Homes
Whether you're in a classic bungalow near Eagle Rock Boulevard or a hillside home near Verdugo Road, your home's age dictates how we approach repairs. Many new homeowners in the area are renovating older properties and want to ensure their HVAC system is up to the task of keeping the home comfortable during our long LA summers.
We provide comprehensive assessments for these properties. We map out the current system condition, identify immediate repair needs, and help you plan for long-term upgrades. This helps you prioritize your budget and avoid unnecessary work while ensuring your system is reliable.
How We Find the Leaks
We don't guess. Our diagnostic process starts with measuring airflow at your registers to see what's actually reaching your rooms. We then perform a duct pressurization test (duct blaster test) to quantify exactly how much air is leaking out of your system.
This testing gives us a clear picture of the problem. We then create a repair plan with written pricing. You'll know exactly what we're doing—whether it's sealing joints with mastic, reconnecting flex duct, or using Aeroseal for inaccessible leaks—before we start any work.
Repair or Replace?
A common question I get is whether it's worth fixing old ducts. If the ductwork is structurally sound but leaking, a repair is almost always the right choice. It saves you money and improves comfort immediately.
However, if the ducts are severely undersized, collapsing, or made of outdated materials that are falling apart, we will tell you honestly that replacement is the better long-term investment. We aren't here to sell you a new system if a repair will do the job, but we also won't suggest a 'band-aid' fix if the system is beyond saving.
Understanding the Costs
Duct repair costs vary based on the scope of the work. A simple repair for a disconnected section might be straightforward, while a full-system seal or Aeroseal application is more involved. We provide a written estimate after our initial diagnostic so there are no surprises.
Remember that the cost of repair is often offset by the energy savings. When your ducts are sealed, your HVAC system doesn't have to run as long to hit your target temperature, which lowers your monthly utility bills.

We serve the entire Glassell Park area from our local hub. We know that hillside access can be tricky, and we plan our service calls to account for equipment placement and site access.

Avoid DIY Pitfalls
I see a lot of 'repairs' done with standard duct tape that falls off after a few months in the attic heat. Real duct repair requires mastic sealant or professional-grade foil tape applied to clean surfaces. If you try to fix a leak yourself and use the wrong materials, you might just be creating a bigger problem for the next technician.
Also, be careful about blocking registers. Some homeowners try to balance their system by closing vents in unused rooms. This can actually increase pressure in your ducts, forcing more air out of the leaks you can't see and potentially damaging your blower motor.
Air Quality and Safety
Duct leaks aren't just about comfort; they're about the air you breathe. If your return ducts are leaking in the attic, your system is pulling in dust, insulation fibers, and potentially mold spores, then blowing them directly into your living space.
Sealing these leaks prevents that attic air from entering your home. It's a simple step that makes a real difference in your indoor air quality, especially during wildfire smoke events or high-dust seasons here in Los Angeles.
Is It Time for a Professional Duct Assessment?
If you notice your energy bills creeping up or specific rooms never seem to get comfortable, it's time for a professional look. We don't just look at the unit; we look at the whole system.
Call LC Heating & Air at (323) 970-3113. We'll come out, test your system, and give you an honest assessment of whether a repair will solve your comfort issues or if it's time to consider other options.

What Glassell Park customers say about duct repair
Verified reviews from homeowners in Glassell Park and nearby neighborhoods who used our duct repair service.
“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.”
“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%.”
