Air Duct Repair in Fort Collins - We Measure the Leak Before We Quote

Trusted Air Duct Repair for Fort Collins Homeowners

If your heating bill climbs while one room stays cold, or you can hear the blower pushing air that never reaches a register, the problem is usually in the ductwork, not the furnace. Air duct repair in Fort Collins means finding the crushed flex run, the disconnected boot, the sagging trunk line, or the joint that’s been leaking into a crawlspace, and fixing it instead of cleaning around it. Our technicians have up to 12 years of experience diagnosing exactly these failures, using Rotobrush agitation, Nikro HEPA extraction, and Abatement Technologies containment so the repair is verified, not guessed at. Same-day repair visits are available in Fort Collins. Call (844) 834-5984 for an honest assessment of what’s actually broken.

HVAC Duct Installation

HVAC duct installation is the design and build-out of a complete duct system, and it’s the right call when the existing layout can’t be saved or when a room addition, converted garage, or finished basement needs its own supply and return runs. It’s also what we recommend when a home has been added onto over the years and each contractor ran ductwork to their own rules, leaving a system that fights itself. Duct Cleaning Fort Collins handles the layout, the sizing, the sealing, and the final balancing so every register actually moves air. A typical whole-home HVAC duct installation in Fort Collins runs $2,800-$7,500 depending on the number of runs, the accessibility of the attic or crawlspace, and whether the trunk line needs to be rebuilt. A single-zone addition usually lands in the lower half of that range; a full system replacement with new trunk and branch lines sits at the top. The written estimate sets the final price.

Sizing and Layout

Duct sizing isn’t guesswork. We measure static pressure and calculate airflow per room so the system delivers what the equipment was rated to move, and that step is what separates a working install from a noisy one. Undersized returns are the most common mistake we find in Fort Collins homes.

Sealing and Insulation

Every joint gets mastic or foil tape, never duct tape alone, and runs through unconditioned attic space get insulated to keep conditioned air from losing its temperature before it reaches the room. Sealing matters in a place where attic temperatures swing hard between summer and winter.

Air Duct Replacement

Air Duct Replacement means removing ductwork that’s beyond repair and installing new runs in its place, and it’s the honest answer when the old ducting is crushed beyond recovery, saturated with moisture damage, or built from materials that are falling apart. Homes built in the 1970s and earlier around Fort Collins often have duct board or early flex that has sagged, torn, or separated at the collar, and patching it costs more over time than replacing it once. We pull the failing sections, contain the work area with Abatement Technologies equipment so debris doesn’t migrate into living space, and install new sealed ductwork that’s properly supported. Air duct replacement in Fort Collins typically runs $1,200-$4,500 depending on how many runs are replaced and how accessible the ductwork is. Replacing a handful of attic runs sits near the low end; a whole system with new trunk lines is at the high end.

When Replacement Beats Repair

If more than a third of the system is compromised, or the ducting has been wet and never dried properly, replacement is the cheaper path over five years. We’ll tell you which side of that line your system is on before any work begins.

Material Choices

Sealed flex, rigid galvanized, and duct board each have a place. We match the material to the space it’s running through rather than defaulting to whatever’s cheapest, and we explain the tradeoffs before you decide.

Ductwork Repair

Ductwork Repair covers the targeted fixes that restore a system without replacing it: resealing separated joints, reconnecting a boot that’s pulled away from a register, straightening a crushed flex run, re-supporting sagging duct, and patching holes chewed or torn open. It’s the right service when the system is fundamentally sound but losing air at the seams, which is the most common problem we see in Fort Collins homes. You’ll usually notice it as a room that never heats evenly, whistling at a register, or dust settling faster than it should. Ductwork repair in Fort Collins typically runs $250-$900 depending on how many leaks or breaks are found and how accessible they are. A few resealed joints is a short job; a disconnected trunk line buried in a tight crawlspace takes longer.

Locating the Leak

We don’t guess. A pressure test and visual inspection of every accessible run tell us where the air is going, and that’s what keeps you from paying to seal joints that were already tight.

Before and After Verification

You get before-and-after photos of your own ductwork, not stock images. That’s how you know the work you were billed for actually happened in your home.

Duct Replacement

Duct Replacement is the removal and reinstallation of specific duct sections, and it applies when a defined portion of the system has failed but the rest is still serviceable. Maybe a trunk line in the crawlspace has rusted through. Maybe a run was crushed during a renovation and never corrected. Maybe the previous homeowner’s DIY flex job came apart. Whatever the cause, we isolate the failed section, contain the work area, and install a properly sealed replacement that matches the rest of the system’s sizing. Duct replacement in Fort Collins usually runs $600-$2,400 for the affected sections, with the number driven by accessibility and how much of the run needs to come out. A single attic run is a quick fix; a trunk line replacement under a low crawlspace takes longer.

Matching Existing Sizing

A replaced section has to match the airflow the rest of the system expects, or you’ve just moved the imbalance somewhere else. We measure before we cut.

Containment During Removal

The moment old ductwork comes apart, years of accumulated dust goes airborne. Abatement Technologies units run during removal so that material gets captured, not redistributed through the house.

Ductwork Installation

Ductwork Installation is the build-out of new duct runs where none exist or where the old layout never worked, and it comes up most often with additions, basement finishes, garage conversions, and homes where a previous owner’s ductwork was added piecemeal without any plan. It’s a design job as much as a labor job. We work out where the supply and return runs need to go, size them for the room’s load, and install them sealed and supported so the system delivers balanced air to the whole house, not just the rooms closest to the furnace. Ductwork installation in Fort Collins typically runs $450-$2,200 depending on the number of new runs and the route they take through the structure. One or two runs into a finished room is straightforward; a multi-room layout in a tight attic takes more planning.

Route Planning

Where a run travels matters as much as how big it is. We look for the shortest, straightest path with the fewest elbows, because every turn costs airflow.

Balancing After Install

Once the runs are in, we check airflow at every register and adjust dampers so the new rooms aren’t stealing air from the rest of the house.

Brands We Service

We service Honeywell and Aprilaire indoor air quality components as part of duct repair work, and we know where each one tends to wear out. Honeywell zone dampers and controls are common in Fort Collins homes with multi-zone systems, and a failed damper is often the reason one area of the house never gets conditioned air even though the furnace is running fine. Aprilaire humidifiers and filtration components tie directly into the duct system, so a duct repair visit is a sensible time to check that they’re functioning and sealed properly.

We also work with Nikro extraction and Abatement Technologies containment equipment, so the repair itself gets done without spreading contaminants through the home. We’re not a dealer and we don’t claim to stock OEM parts, but we can identify what’s failing and tell you honestly whether it needs service or replacement. Whether you have Honeywell or Aprilaire equipment or any other make, we can help.

Signs You Need a Pro Right Now

• Uneven room temperatures. If one room stays cold in winter and hot in summer no matter what you set the thermostat to, the duct run feeding it is likely disconnected, crushed, or leaking. That’s a repair problem, not a furnace problem, and it won’t fix itself.
• Whistling or roaring at a register. A whistle usually means a restricted or undersized run; a roar can mean a separated joint pulling attic air into the system. Both signal a break you can’t see.
• Dust returning within days of cleaning. If dust settles fast after a professional cleaning, the cleaning wasn’t the issue. Leaking joints are pulling unfiltered air in from the attic or crawlspace.
• Higher energy bills with no other explanation. A duct system leaking conditioned air into unconditioned space makes your equipment work harder for less result. The waste shows up on the bill before it shows up anywhere else.
• Visible damage or collapse. A crushed flex run, a sagging trunk line, or ductwork hanging loose from its supports needs attention before it tears further. Get it assessed before the next heating season.

Our Process, Step by Step

1. 1
   Diagnostic inspection. We inspect every accessible run and measure system static pressure to find where the air is actually going. This is where we determine whether you need a repair, a replacement, or new installation, and we tell you which one and why.
2. 2
   Written estimate. You get a written estimate before any work starts, and the price is set per job. No per-vent pricing, no teaser number that grows once the technician is inside.
3. 3
   Containment setup. We set up Abatement Technologies containment so dust and debris from the repair stay captured rather than migrating into your living space. This step matters most during replacement work.
4. 4
   Repair or installation. We make the repair, seal the joints with mastic or foil tape, and re-support any ductwork that was sagging. Rotobrush agitation cleans the surfaces we’re working on, and Nikro HEPA extraction pulls the loosened material out of the system.
5. 5
   Verification and walkthrough. We test airflow after the work and walk you through before-and-after photos of your own ductwork. You’ll know exactly what changed.
