LC Heating & Air provides duct cleaning in Los Feliz — 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 Los Feliz, 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.

When homeowners search for duct installation in Los Feliz, they are usually trying to solve a real comfort problem quickly: no cooling, uneven rooms, a noisy system, rising utility bills, or equipment that finally stopped responding. LC Heating & Air treats this page as a local service guide, not a generic directory listing. The goal is to explain what tends to happen in Los Feliz homes, what we check first, and how we help you decide between repair, maintenance, and replacement.

Los Feliz is one of the most architecturally distinct neighborhoods in Los Angeles — home to a dense concentration of 1920s and 1930s Spanish Colonial Revival and Mediterranean-style homes, many with original plaster walls, tile roofs, and architectural features that make HVAC installation and ductwork routing genuinely challenging. LC Heating & Air has worked in Los Feliz homes for two decades and understands the unique requirements of older construction: how to run new ductwork without destroying original plasterwork, where to locate condensing units on tight hillside lots, and how to size systems correctly for older homes with different insulation and window characteristics than modern construction. The 90027 zip code encompasses both flat residential streets near Vermont Avenue and steep hillside properties in the hills above Los Feliz Boulevard. We service both areas with equal competence and respond quickly — our Fairfax Avenue base puts us 15 to 20 minutes from Los Feliz under normal traffic.. An affluent, creative neighborhood bordering Griffith Park. Those local details matter because HVAC performance changes with building age, attic conditions, sun exposure, duct layout, utility provider, and equipment access. A recommendation that makes sense in a coastal condo may not make sense in a Valley attic or a hillside home with a long refrigerant line-set.

### New Duct Installation in Los Angeles Homes Installing new ductwork is required when adding central HVAC to a home that has never had it, when existing ductwork is so deteriorated that repair isn't cost-effective, or when a major renovation creates the opportunity to redesign a poorly performing duct system. LC Heating & Air designs and installs complete duct systems throughout Los Feliz County using flex duct, sheet metal, and duct board construction depending on the application.

Every duct installation appointment in Los Feliz starts with a diagnostic, photos when useful, and a clear written estimate. We explain the failure, the likely cause, the realistic lifespan of the repair, and any rebate, permit, airflow, or efficiency issue that could affect the decision. If repair is the smart move, we say so. If replacement would save money over repeated repairs, we explain that too.

Duct Installation issues we commonly see in Los Feliz

For duct installation in Los Feliz, return sizing, duct leakage, crushed flex runs, insulation, register balance, and attic heat gain are shaped by slope, sun exposure, access, and long refrigerant or duct runs can create room-by-room comfort differences. Fixing airflow can make the entire HVAC system work better before equipment is blamed.

In the 90027 area, the local context is important: sun exposure, slope, wind, tree cover, and elevation changes can create room-by-room comfort differences. That is why our diagnostic process checks the whole system instead of only replacing the first failed part we find.

How Los Feliz homes affect duct installation

Los Feliz properties often include hillside homes, canyon properties, estate lots, older custom homes, and tight-access mechanical areas. For duct installation, that means we look at airflow, insulation, condenser placement, thermostat location, return sizing, electrical capacity, and whether the existing system was sized correctly in the first place.

equipment placement, ladder access, line-set routing, and service clearances must be planned around slopes and narrow roads These details make the work more predictable and help avoid callbacks, noise problems, poor airflow, and equipment that is difficult to service later.

Our duct installation process in Los Feliz

First, we confirm the symptoms with you and inspect the equipment under real operating conditions. For duct installation, the diagnostic focus is return sizing, duct leakage, crushed flex runs, insulation, register balance, and attic heat gain. For installation calls, we also review sizing, duct condition, placement, permit needs, utility requirements, and comfort goals.

Second, we explain the findings in plain English and provide a written estimate. The estimate separates must-fix items from optional improvements, so you can make a practical decision without sales pressure. Third, we complete the approved work, test the system through a full cycle, and document what changed.

Repair, replace, or maintain?

For duct installation in Los Feliz, the best choice depends on age, repair history, equipment condition, efficiency, and how long you plan to stay in the home. A simple capacitor, thermostat, drain, ignitor, or sensor problem is often worth repairing. Repeated compressor, heat exchanger, coil, refrigerant, or control-board failures may point toward replacement.

We do not assume the most expensive answer is the right answer. Our job is to show you the facts: what failed, what it costs, how long the fix should last, and whether rebates, financing, or energy savings change the math.

Overview

### Duct System Design A properly designed duct system is engineered, not improvised. We use Manual D (the ACCA standard for duct design, companion to Manual J) to calculate supply and return duct sizing for each room, determine optimal supply register locations and throw patterns, calculate system static pressure to ensure the air handler's fan can deliver the designed airflow, and route the duct system to minimize length and bends. A well-designed duct system delivers comfort; a poorly designed one creates complaints that no amount of equipment maintenance will resolve.

### Types of Ductwork We Install Flex duct is the most common residential duct material in LA — it's flexible, relatively inexpensive, and can navigate around obstructions in attic spaces. Sheet metal ductwork is used for main trunk lines, supply plenums, and in applications where durability and airflow efficiency are prioritized. Duct board (fiberglass board) is used in some applications, particularly for custom plenums. We select the appropriate material for each application.

### Insulation and Code Requirements All ductwork in unconditioned spaces (attics, crawl spaces) must be insulated per California Title 24. New duct installation includes R-8 insulation wrapping on all sections in unconditioned spaces, proper duct sealing with mastic at all joints, and a duct leakage test as part of the permit sign-off process.

Local HVAC Challenges

Los Feliz's older housing stock presents three consistent HVAC challenges: original ductwork that is undersized for modern comfort expectations, plaster-and-lath construction that complicates new duct runs, and hillside lots with limited space for outdoor condenser placement. We use flexible installation approaches including mini-split systems for rooms that cannot be served efficiently by a central duct system, and we always photograph and document duct routing before closing walls so homeowners have records of what is in their walls.

Neighborhood Context

Many Los Feliz homes have partially original duct systems — galvanized steel trunk lines from original installations combined with flex duct extensions added in various decades. This patchwork ductwork is a common source of efficiency problems, hot and cold spots, and duct leakage. We assess the full duct system during every installation project and recommend consolidation or replacement when the existing ductwork would significantly compromise new equipment performance.

Why Choose Us

Manual D design: We size every duct run and register using proper engineering calculations — ensuring balanced airflow to every room from day one.
CA Title 24 compliant: All new ductwork meets current California energy code requirements for insulation, sealing, and leakage testing.
All duct types: Flex duct, sheet metal, and duct board — we select the right material for each application and location.
Permitted and inspected: New ductwork requires a permit in California. We pull all required permits and coordinate the final inspection.

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.

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.

Frequently asked questions

Duct Installation in Los Feliz — common questions

How fast can LC Heating & Air respond to a duct installation call in Los Feliz?
We offer same-day duct installation service throughout Los Feliz. For emergencies, we aim to arrive within 60–90 minutes. Call (323) 970-3113 any time — we answer 24/7.
Is LC Heating & Air licensed to do duct installation work in Los Feliz?
Yes. LC Heating & Air holds California Contractors State License Board license #1073586. We are fully licensed and insured for all HVAC work in Los Feliz and throughout LA County.
Do you provide a free written estimate for duct installation in Los Feliz?
Yes. Every job starts with a free written estimate. You approve the price before we touch anything. No surprises, no mystery charges. If we find additional issues during the job, we discuss them with you before doing any additional work.
How much does new duct installation cost in Los Angeles in Los Feliz?
New duct installation for a typical 1,500–2,000 sq ft LA home runs $3,000–$7,000 depending on the complexity of the routing, number of rooms, and duct material selection. Larger homes and complex installations cost more. We provide a written estimate after reviewing your home's layout and the proposed HVAC system.
How long does duct installation take in Los Feliz?
A complete new duct installation for a typical LA single-family home takes 1–3 days depending on complexity. Homes requiring extensive wall penetrations or difficult attic access take longer. We provide an accurate timeline in the project proposal.
Can ductwork be added to any home in Los Feliz?
In most homes, yes — though the cost and invasiveness varies significantly. Homes with large attic spaces (common in LA) are the easiest — ductwork routes through the attic with minimal wall penetration. Homes with flat roofs, concrete construction, or no attic access require more creative routing solutions that increase cost. For some homes, a ductless mini split system is a more practical solution.
What is Manual D duct design in Los Feliz?
Manual D is the ACCA standard for residential duct system design. It calculates the required airflow for each room (from the Manual J load calculation), sizes each duct section to deliver that airflow without excessive friction loss, and determines register sizes and locations for optimal air distribution. It's the engineering basis for a duct system that actually performs as designed.
What insulation is required on new ductwork in LA in Los Feliz?
California Title 24 requires minimum R-8 insulation on all ductwork in unconditioned spaces (attics, crawl spaces). We install R-8 flex duct and R-8 wrap on all sheet metal sections in unconditioned spaces as standard on every installation.
