Duct Sealing & Insulation in Pueblo — Stop Paying to Heat Your Attic

Leaky ductwork wastes 25 to 40 percent of the energy your HVAC system produces. That means nearly a third of every heating and cooling dollar you spend goes into your attic, crawlspace, or walls — not into your living spaces. Sealing and insulating your ducts is one of the most cost-effective home improvements you can make.

The Hidden Problem in Pueblo Homes

Most Pueblo homeowners don't think about their ductwork. It's hidden in attics, crawlspaces, and between walls — out of sight, out of mind. But the reality is that the average home's duct system leaks 20 to 30 percent of the conditioned air it carries. In some older Pueblo homes, particularly those built in the 1950s through 1970s when duct construction standards were minimal, leakage rates exceed 40 percent.

That means your furnace or air conditioner is working significantly harder than it should be to maintain the temperature you set on your thermostat. The conditioned air leaking into your attic, crawlspace, or wall cavities doesn't just waste energy — it creates pressure imbalances that pull in unfiltered outside air through gaps and cracks in your home's envelope. That dusty, unfiltered air carries allergens, contaminants, and humidity straight into your living spaces.

Duct Sealing & Insulation Solutions

Manual Duct Sealing

We seal accessible duct joints, connections, and boot-to-floor transitions with UL-listed mastic sealant and metal-backed tape. Effective for exposed ductwork in basements, utility rooms, and accessible attic sections.

Aeroseal Technology

Computer-controlled system that seals ducts from the inside. Polymer particles carried by air pressure find and seal leaks automatically — including those hidden in walls and between floors. Measurable before-and-after leakage results provided.

Duct Insulation

Ducts running through unconditioned spaces — attics, crawlspaces, garages — lose or gain heat through their walls. We wrap exposed ductwork with R-8 insulation to prevent thermal losses that undermine your HVAC system's efficiency.

Duct Repair & Replacement

Crushed flex ducts, disconnected joints, and deteriorated sections that are beyond sealing need to be repaired or replaced. We replace damaged ductwork with properly sized and sealed new sections to restore full airflow.

Warning Signs

Signs Your Pueblo Ducts Need Sealing

High Energy Bills

Bills climbing despite similar usage patterns — your HVAC is compensating for lost conditioned air through duct leaks.

Rooms That Won't Cool/Heat

Some rooms stay warm in summer or cold in winter while others are comfortable — a classic sign of duct leaks or disconnections.

Excessive Dust

Leaky return ducts pull dusty, unfiltered air from attics and crawlspaces into your system and blow it through your home.

HVAC Runs Constantly

Your system runs much longer than expected to reach the set temperature — it's fighting against air losses in the ductwork.

Questions

Duct Sealing FAQs

Manual duct sealing for accessible sections typically costs $300 to $800. Aeroseal duct sealing for the entire system ranges from $1,500 to $3,000, depending on the system size and leakage severity. Duct insulation adds $500 to $1,500 depending on the linear feet of exposed ductwork. Most homeowners see a full payback within three to five years through lower energy bills.

We use a duct pressure test to measure total system leakage. A calibrated fan pressurizes your ductwork and instruments measure how much air escapes. This tells us the severity of your leaks and helps quantify the improvement after sealing. For visual inspection, we use cameras in accessible sections to locate specific leak points.

Aeroseal is a patented technology that seals ducts from the inside. We temporarily seal all your registers, inject aerosolized polymer particles into the pressurized duct system, and the particles naturally accumulate at leak points — sealing them from the inside. The computer tracks leakage reduction in real time. It can seal leaks up to 5/8 inch in diameter, including those in walls and between floors that are impossible to reach by hand.

Despite its name, standard duct tape is actually one of the worst materials for sealing ducts. It dries out and falls off within one to two years, especially in the temperature extremes inside Pueblo attics. Professional duct sealing uses mastic sealant (a thick paste that hardens but remains flexible) or metal-backed UL-listed tape designed specifically for HVAC applications.

Yes — it's often the single biggest comfort improvement you can make. Sealed ducts deliver more conditioned air to your rooms, which means more even temperatures, better airflow at registers, and a system that actually reaches the thermostat setting without running constantly. Rooms that were always too hot or too cold often become comfortable after duct sealing.
