Duct Cleaning & Air Duct Service in Van Nuys

LC Heating & Air provides duct cleaning in Van Nuys — 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.

We repair and service all major HVAC brands in Van Nuys, including Carrier, Trane, and Goodman, and older or discontinued units. No matter the manufacturer, we diagnose the problem accurately and give you an upfront price before any work begins.

Van Nuys is the geographic and commercial heart of the San Fernando Valley, and at LC Heating & Air, we know the specific challenges this area presents. From the older single-family homes near the Civic Center to the dense apartment corridors along Sherman Way, we see a lot of systems that have been pushed to their limit. When your HVAC system runs, it should be cooling your living space, not the hot air in your attic.

The Department of Energy estimates that typical residential duct systems lose 20–30% of conditioned air through leaks. In Van Nuys, where summer temperatures routinely hit 95-100 degrees, those leaks mean your AC has to work much harder and run longer just to keep your home comfortable. We provide honest, practical duct repair to help your system perform the way it was designed to.

Local HVAC considerations

Service Area

Van Nuys (91401, 91405, 91411) and surrounding Valley neighborhoods.

Common Access Points

Attic spaces, crawl spaces, and wall cavities.

Common Duct Issues in Van Nuys Homes

In Van Nuys, we frequently see systems that have been maintained reactively rather than proactively. Many homes in the 91401 area feature older attic duct systems that have suffered from years of heat exposure and neglect. We often find disconnected duct sections at joints, torn inner liners in flex duct, and crushed runs caused by foot traffic in tight attic spaces.

For multi-family buildings and apartment complexes, the challenge is often deferred maintenance. We see systems running well past their expected life span with ductwork that has never been sealed. Whether it is a single-family home or a larger property, our goal is to identify the specific leaks and provide a repair plan that makes sense for your budget and the equipment's condition.

How local homes affect your system — Duct Repair in Van Nuys

Age of construction and retrofit history in Van Nuys change duct paths, electrical capacity, and where duct repair equipment can be serviced safely.

Tighter envelopes and added ADUs often mean load has shifted even when the original HVAC was left unchanged.

How we diagnose the issue — Duct Repair in Van Nuys

Our duct repair diagnostic in Van Nuys includes electrical checks, refrigerant or combustion verification (as applicable), and airflow measurement at registers.

You get plain-language findings and photos when something needs attention — not a laundry list of upsells.

Repair vs replace — an honest call — Duct Repair in Van Nuys

If duct repair repair costs approach a significant share of replacement value, we lay out both paths with realistic timelines for Van Nuys permitting when needed.

We will recommend repair when the equipment has safe, useful life remaining.

Cost factors and rebates — Duct Repair in Van Nuys

Duct Repair pricing in Van Nuys reflects access, parts lead time, and whether rebates (IRA, TECH Clean California, or utility programs) apply to your equipment type.

Written estimates follow site review; call (323) 970-3113 to schedule.

Scheduling and access — Duct Repair in Van Nuys

Parking, gate codes, and attic or rooftop access in Van Nuys are confirmed when you book duct repair service so the crew arrives with the right ladders and PPE.

Mistakes to avoid — Duct Repair in Van Nuys

Oversized equipment, skipped maintenance, and DIY refrigerant or gas work are frequent duct repair mistakes we correct in Van Nuys.

Closing too many registers or using the wrong filter MERV rating can starve airflow and shorten component life.

Health, safety, and indoor air — Duct Repair in Van Nuys

Combustion appliances, electrical connections, and condensate routing all affect safety during duct repair work in Van Nuys.

We follow CSLB #1073586 standards and leave systems tested before we leave the property.

Repair vs. Replacement: Making the Right Call

I always tell homeowners that the estimate should make sense before anyone touches the equipment. If your ductwork is generally in good shape but has a few disconnected runs or failed mastic joints, a targeted repair is often the right move. We focus on the most impactful fixes first to restore airflow and efficiency.

However, if the duct system is severely undersized, crushed beyond repair, or made of outdated materials that are falling apart, we will be honest with you about the limitations of a repair. If the pattern points to replacement, we will explain why. Our job is to give you a clear, practical assessment so you can make an informed decision for your home.

Sunday evening, 95 degrees, AC completely dead. LC answered immediately and had a tech here in 90 minutes. Got us cooling again that night. Wouldn't go with anyone else.

AC wouldn't turn on at all. LC came same morning, found a tripped high-pressure safety switch due to dirty condenser coils. Cleaned the coils, reset the switch, tested everything. Done in 90 minutes.

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.

Frequently asked questions

Duct Repair in Van Nuys — common questions

How do I know if my ducts are leaking?
The clearest symptom is rooms that are consistently harder to heat or cool than others, combined with high energy bills. Dusty supply registers can indicate return duct leaks drawing unconditioned attic air.
Who offers duct repair near me in Van Nuys?
LC Heating & Air provides duct repair in Van Nuys and nearby LA neighborhoods, with same-day scheduling when available. Emergency calls are answered 24/7, typically within 30 minutes — call (323) 970-3113. Licensed CSLB #1073586.
How much does duct repair cost in Los Angeles?
Targeted repairs typically range from $200–$600. Comprehensive sealing can range from $800–$2,000, while Aeroseal for hard-to-access leaks ranges from $1,500–$3,000. We provide a written estimate after the diagnostic.
Can I repair ducts myself?
Accessible flex duct reconnections are DIY-possible, but most significant leakage occurs in difficult-to-access attic spaces. Improper repairs can make airflow issues worse.
What is Aeroseal duct sealing?
Aeroseal is a process that seals ducts from the inside using adhesive polymer particles. It is highly effective for leaks in inaccessible sections of your ductwork.
Will duct repair help my HVAC system last longer?
Yes. Sealed ducts reduce equipment runtime, which lowers the duty cycle on your compressor and blower motor, helping components last longer.
