Expert Ductwork
Installation & Repair

Northern Colorado

Your home’s ductwork is the foundation for heating and cooling. Without properly sealed, installed, or old ductwork, your home’s HVAC system won’t be nearly as efficient as it should be. We specialize in installing and repairing ductwork. We also install exhaust fans, vent hoods, and dryer exhaust systems.

 

Why Proper Ductwork Matters

Even the most efficient furnace or air conditioner can’t deliver consistently if ductwork is leaky, crushed, undersized, or poorly routed.

Well-designed, properly sealed ductwork:

  • Delivers air evenly to every room
  • Improves system efficiency and reduces energy bills
  • Helps maintain healthy indoor air quality
  • Prevents hot/cold spots and weak airflow
  • Reduces wear and tear on your HVAC system

Whether you’re building, remodeling, or correcting poor airflow in an existing home, we’ll ensure your ductwork supports year-round comfort and efficiency.

 

Duct Installation

Whether you need an entire HVAC replacement or simply repairing ductwork, we build systems designed to:

  • Minimize air loss and pressure drops
  • Work with your existing heating and cooling equipment
  • Meet current building codes and airflow standards

We take care of sealing, insulating, and supporting every run to ensure long-term performance.

 

Duct Repair

Common duct issues we fix:

  • Leaks at joints or seams
  • Crushed, sagging, or disconnected ducts
  • Improper sizing or airflow imbalance
  • Poor insulation around the attic or crawl space ducts

Poor ductwork can waste 20-30% of your HVAC unit’s efficiency. That’s money vanishing into your attic or walls. We’ll find the problem, seal it properly, and restore your airflow and efficiency.

If your rooms aren’t staying the same temperature, ductwork issues may be present.

We don’t offer duct cleaning because we believe that resolving airflow and air quality issues begins with addressing the duct system, not just cleaning it out.

 

Ventilation System Installation

Good ventilation helps remove stale air, odors, moisture, and pollutants from your home, especially in areas such as bathrooms, kitchens, and laundry rooms.

We install:

Exhaust Fans

  • Bathroom exhaust fans to remove humidity and prevent mold
  • Quiet, high-efficiency models available
  • Ducted adequately to the exterior (no attic venting shortcuts)

Vent Hoods

  • Ducted kitchen range hoods for gas or electric stoves
  • Horizontal or vertical duct runs depending on your kitchen layout
  • It helps remove smoke, grease, and cooking odors

Dryer Exhaust

  • Safe, code-compliant dryer vent installations
  • Metal ductwork for fire safety (no plastic flex ducts)
  • Proper vent termination outside the home
  • Reduced risk of dryer fires and moisture buildup

Many homes have outdated or hazardous dryer vents; we install new systems that enhance safety and improve drying efficiency.
