HVAC Duct Installation
HVAC Duct Installation is the process of designing and fitting an entirely new duct system when your existing runs are beyond repair, improperly sized, or absent altogether. For homeowners nearby, we also offer Ladera Ranch Air Duct Repair services. You need this when ducts have collapsed, sustained fire or water damage, or when a home addition requires extending airflow into new square footage. In Mission Viejo, homes built in the 1970s and 1980s often have original galvanized ductwork that’s now rusted through or leaking at the seams. We replace those systems with modern, properly sealed ductwork sized for your actual airflow needs. Whole-home HVAC duct installation typically ranges from $3,500 to $7,500 depending on home size and complexity.
New Construction and Additions
A Mission Viejo room addition without proper ductwork means one space stays uncomfortable year-round. We calculate the correct duct sizing for the new square footage, matching branch runs to your existing system’s capacity. The install includes sealed connections at every joint, not tape that peels after one season.
Replacing Undersized Systems
Some homes in Lake Forest and Laguna Hills were built with ducts that were marginal from day one. You’ll notice weak airflow in far bedrooms, hot and cold spots, and a system that runs constantly. We assess static pressure before recommending replacement, so you’re not buying ductwork you don’t need.
Air Duct Replacement
Air Duct Replacement means removing and replacing damaged sections of your existing duct system, not the entire network. You need this when specific runs are crushed, torn, mold-contaminated, or so leaky that sealing won’t recover reasonable efficiency. In South Orange County, the most common culprit is flex duct in attics that rodents have chewed through or that heat has degraded over 15-plus years. We quote replacement per affected section, typically $400 to $1,200 per run depending on length, diameter, and attic accessibility in your Mission Viejo home.
Crushed and Restricted Runs
A duct that’s been crushed by stored boxes, a misstep in the attic, or original installation shortcuts restricts airflow and drives up your energy bill. We rebuild these runs with properly supported, code-compliant materials. The difference in room comfort is immediate.
Mold and Contamination
When Abatement Technologies testing confirms biological growth inside ductwork, cleaning is often not enough. Porous flex duct with mold penetration should be replaced, not scrubbed. We handle containment and replacement so the problem is removed, not just treated.
Ductwork Repair
Ductwork Repair covers the broad category of fixes that restore a damaged duct system without replacing it. That includes sealing separated joints, patching small holes, reconnecting disconnected boots, and re-hanging sagging trunk lines. Most Mission Viejo homeowners discover they need ductwork repair after a cleaning reveals damage, or when energy bills climb despite a well-maintained HVAC system. The EPA estimates the average home loses 20-30% of conditioned air through duct leaks. We seal with mastic and mesh, not duct tape, and typical repairs run $250 to $700.
Sealing Leaks and Separations
The seams on older sheet metal ducts in Rancho Santa Margarita and Mission Viejo homes loosen over decades of thermal expansion. That means air you paid to heat or cool is escaping into the attic. We re-secure and seal every accessible joint in the affected run.
Reconnecting Disconnected Runs
A duct boot that separates from the floor register sends air into the crawlspace instead of the room. You’ll notice weak airflow, dustier rooms, and warmer floors. We reconnect and properly fasten boots, then test airflow at the register to confirm the fix.
Duct Replacement
Duct Replacement is the complete removal and replacement of all ductwork in your home, usually indicated when the system is 20-plus years old, consistently failing, or when a previous installation was done badly. In Mission Viejo, we see this most often in homes where original ductwork is undersized for modern heat pump systems or where multiple past repairs have created a patchwork of incompatible materials. Complete duct replacement for a 2,000-square-foot home typically ranges from $4,500 to $8,000, including sealed connections and final airflow verification.
Full System Replacement
When you’re replacing your HVAC equipment anyway, it’s often the right moment to replace aging ducts. A new high-efficiency system connected to old, leaky ductwork wastes what you just spent. We coordinate with your equipment timeline so the entire system works as designed.
Post-Disaster Replacement
Fire, flood, or a contractor’s misstep can make duct replacement the only responsible option. We document what was damaged, work through insurance claims when helpful, and get your home back to safe, conditioned comfort. The job is done to current code, not whatever was acceptable in 1985.
Ductwork Installation
Ductwork Installation refers to fitting the physical duct system into a home, including supply and return trunks, branch runs, and register connections. You need this when converting a space that was never ducted, like a garage conversion in Aliso Viejo, or when replacing a system that was never installed correctly. We handle layout, sizing calculations, and a clean install that respects your attic and crawlspace access points. New ductwork installation for a standard conversion or addition in Mission Viejo runs $2,500 to $5,500 depending on run count and home configuration.
Return Air Corrections
Many South Orange County homes lack adequate return air, which chokes system performance. Adding a return drop and properly sized ductwork restores balanced airflow and reduces pressure on your blower. It’s one of the highest-impact duct changes we make.
Proper Sizing from Day One
We calculate duct sizing using Manual D principles, not rules of thumb. Too-large ducts reduce air velocity and comfort, while too-small ducts are noisy and inefficient. The result is a system that delivers even temperatures room to room, including the far bedroom that’s always been a problem.
Brands We Service
We work with Rotobrush and Nikro systems daily in Mission Viejo homes. These are the industry-standard platforms for source-removal duct cleaning, and they let us see inside your ductwork with real-time camera feed before and after the work. It’s professional-grade equipment, not rental-grade tools, and the difference shows in what we find and what we leave behind.
For homes needing better filtration after a repair, we supply and install Aprilaire and Honeywell air-quality products. Honeywell’s whole-home media filters and Aprilaire’s purification systems integrate with your existing HVAC equipment. We also use Guardsman protective products during the service process to keep your Mission Viejo home clean while we work. Whether you have a standard residential system or a specific brand configuration, we can help.

- One room never matches the thermostat. A single room that’s consistently hotter or colder than the rest of the house usually points to a duct problem, not a thermostat problem. It means air isn’t arriving where it should.
- You hear whistling or rattling from vents. Air escaping through small holes makes a whistle; loose metal makes a rattle. Both mean conditioned air is leaking somewhere it shouldn’t be.
- Your energy bill climbs without explanation. Duct leaks mean your system runs longer to hit the same temperature. That shows up as a rising bill even when rates haven’t changed.
- Dust returns days after cleaning. If your Mission Viejo home gets dusty immediately after house cleaning, the ducts are likely pulling attic or crawlspace air straight into the living space through gaps and disconnections.
- Musty smell when the system runs. Moisture intrusion inside ductwork creates odors that cleaning only temporarily masks if the source is a leak or a torn return pulling damp air. The leak has to be repaired, not just cleaned.
Our Process, Step by Step
- 1
Inspection with camera diagnostics. We send a Rotobrush or Nikro inspection camera through your duct system to document exactly what’s happening. You see the damage on our monitor, so there’s no mystery about what needs fixing.
- 2
Written scope of work. Alan reviews the camera findings with you and provides a written scope with a flat price before any work starts. No per-vent pricing games, no surprise add-ons after we start.
- 3
Approved repair plan. You decide what gets fixed based on our honest assessment. We’ll tell you when a section can be sealed versus when it genuinely needs replacement, and why.
- 4
Repair and verification. We complete the repair using mastic, foil tape, and quality replacement materials where needed. After the work, we verify airflow at each register and pressure-test the repaired section.
- 5
Post-repair cleaning. If the repair involved contaminated materials or loose debris, we run a full source-removal cleaning of the affected ductwork so you’re not blowing construction dust through the home. Guardsman protective products keep the work area clean.
How Much Does Air Duct Repair Cost in Mission Viejo?
A typical air duct repair in Mission Viejo runs $250 to $900 for common fixes like sealing a separated joint, patching a small tear in flex duct, or reconnecting a fallen boot. Sectional replacements of damaged runs typically run $400 to $1,200 per run. Full duct replacement in a 2,000-square-foot home ranges from $4,500 to $8,000. What affects your price: attic or crawlspace accessibility, the age and type of existing ductwork, how many runs are damaged, and whether the repair requires any drywall access cuts. Homes on the hillsides of Mission Viejo often have tight attic access that adds labor time.
To avoid overpaying, get a camera inspection. Any company that quotes without looking inside your ducts is guessing. We include the inspection and a written scope with a flat price for the entire job before work begins. That’s the number you pay, not a starting point. Also confirm whether the quote includes sealing all joints in the repaired area, not just the obvious break. Our free estimate includes the camera inspection, the written quote, and our honest recommendation on repair versus replacement for every affected run. Call (833) 593-4407 to book yours.
