LC Heating & Air provides professional duct diagnostics and repair for Beverly Crest homes. We fix leaks, crushed flex ducts, and airflow issues to restore comfort and efficiency.
If your home in Beverly Crest has rooms that never seem to get comfortable, or if your energy bills are higher than they should be, the problem often isn't your AC unit itself—it's the ductwork. As a local contractor, I see many homes in the Santa Monica Mountains where the duct system is leaking conditioned air into the attic or crawl space, forcing the HVAC system to work twice as hard to reach the thermostat setpoint.
At LC Heating & Air, we don't believe in guessing. We use diagnostic tools to find exactly where your system is losing air. Whether it's a disconnected flex duct or a leaky plenum, we provide a clear, written estimate for the repair so you know exactly what you're paying for before we start.

Common Duct Issues in Beverly Crest
Beverly Crest homes often face unique challenges due to our coastal climate and the age of the housing stock. We frequently find crushed flex ductwork in tight attic spaces, which restricts airflow to specific rooms. Additionally, the marine-layer humidity and salt-air exposure can cause older tape joints to fail prematurely, leading to significant air leakage.
Another common issue we see is return air leakage. If your return ducts are leaking in the attic, they pull in hot, dusty air, which then gets pushed through your filter and into your living space. This doesn't just hurt your comfort; it impacts your indoor air quality.
Ductwork in Coastal and Mountain Homes
Whether you live in a classic coastal property or a renovated home with a modern high-efficiency system, the ductwork is the circulatory system of your house. In many local homes, the original duct design was never balanced for the current cooling loads we experience during our long, hot summers.
We look at how your ducts are routed, the condition of the insulation, and whether the registers are actually delivering the air they were designed to. If the ductwork is undersized or poorly routed, even a brand-new AC unit will struggle to keep you comfortable.
Our Diagnostic Process
We start by measuring the airflow at your registers. If one room is 10 degrees warmer than the rest of the house, we need to know why. We use duct pressurization testing—often called a duct blaster test—to quantify exactly how much air your system is losing.
This test gives us a baseline. Once we identify the leaks, we show you the evidence. We don't just patch things up; we verify the repair by re-testing the system so you can see the improvement in the airflow numbers.
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 a few leaks at the joints, a professional repair is usually the right move. It's cost-effective and gets the system back to peak performance.
However, if the ducts are severely undersized, crushed beyond repair, or made of outdated materials that are falling apart, replacement might be the better long-term investment. I will always give you an honest assessment of whether a repair will actually solve your comfort problem or if it's just a temporary fix.
Understanding Repair Costs
The cost of duct repair varies based on the extent of the damage and how hard it is to get to the ducts. Simple repairs to accessible sections are straightforward, while sealing a full system or using Aeroseal for hidden leaks requires more time and specialized equipment.
We provide a written estimate after our diagnostic. You won't find any surprise fees here. We focus on the work that provides the most value for your home's comfort.
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 logistics of working in Beverly Crest, including roof access and the need for careful routing in tight spaces.
We arrive prepared to diagnose and, in many cases, perform the necessary repairs on the same visit if the scope is clear and parts are available.
Mistakes to Avoid
The biggest mistake I see is homeowners trying to use standard duct tape on leaky joints. Standard tape dries out and fails quickly in the heat of an attic. We use professional-grade mastic and foil tape designed to last.
Another mistake is ignoring the return side of the system. Many people focus only on the supply ducts, but if your return is leaking, you are pulling in attic air, which defeats the purpose of sealing the supply side. We look at the entire system to ensure a balanced result.
Health and Safety
Duct leaks aren't just an efficiency problem; they are an air quality problem. When your ducts leak in an attic or wall cavity, they can pull in insulation fibers, dust, and mold spores. By sealing these leaks, we prevent that contaminated air from circulating through your home.
We also ensure that all repairs are done safely, keeping the structural integrity of your home in mind and ensuring that no debris is left behind in your ventilation system.
Is Your System Ready for Repair?
If you are tired of uneven temperatures and high energy bills, the first step is a professional diagnostic. We don't push for replacement unless the system is truly beyond repair. If the equipment is in good shape but the distribution is failing, we will fix the distribution.

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