Duct Insulation That Stops Energy LossPortland Metro Homes
Bare ducts in your attic and crawlspace are bleeding energy every day. Wrapping them cuts costs, stops condensation, and makes every room more comfortable.
What Duct Insulation Does for Portland Homes
Watch how insulating exposed ductwork cuts energy waste and stops condensation in Portland's damp climate.
Bare Ducts Are Costing You Money
Bare or poorly insulated ducts in your attic and crawlspace lose 20–30% of conditioned air before it ever reaches your rooms. In Portland — with damp winters, summer heat, and constant temperature swings — that's hundreds of dollars a year wasted. Uninsulated ducts also sweat condensation that feeds mold, especially in our crawlspaces. We install code-compliant insulation with vapor barriers to keep your air where it belongs and your ducts dry.
What Insulating Your Ducts Actually Does
The results are measurable — lower bills, more even temperatures, and ducts that stay dry instead of growing mold.
Lower Energy Bills
Save 10–20% on heating and cooling costs by keeping conditioned air in your living spaces — not radiating it into the attic or crawlspace.
Consistent Comfort
Eliminate hot and cold spots throughout your home. Insulated ducts deliver air at the temperature your thermostat promises.
Prevent Mold & Moisture
Portland's humidity causes condensation on cold ducts. Proper insulation with vapor barriers prevents mold growth and duct deterioration.
Extended HVAC Life
When your ducts don't leak conditioned air, your furnace and AC work less hard. This reduces wear and extends equipment lifespan.
Quieter Operation
Insulation dampens the sound of air moving through your ducts, reducing noise from your HVAC system throughout your home.
Code Compliance
Oregon requires R-8 minimum for ducts in unconditioned spaces. We ensure your ductwork meets or exceeds current energy codes.
5 Signs Your Ducts Need Insulation
High Energy Bills Without Explanation
PGE or NW Natural bills creeping up but your habits haven't changed? Bare ducts could be dumping 20–30% of your conditioned air into unconditioned spaces.
Rooms That Won't Heat or Cool Properly
Hot or cold spots in your home often indicate that conditioned air is escaping through uninsulated ducts before reaching distant rooms.
Visible Condensation on Ducts
Cold metal ducts sweat in Portland's humidity. If you see moisture or water stains on exposed ductwork in the attic or crawlspace, insulation is way overdue.
Mold or Musty Odors
Condensation on uninsulated ducts leads to mold growth. If you smell musty odors when your HVAC runs, moisture issues in your ductwork may be the cause.
Ducts in Unconditioned Spaces
If ductwork runs through your attic, crawlspace, or garage without insulation, you're hemorrhaging energy — especially during Portland's long heating season.

Professional installation using quality materials and proven techniques for lasting results.
Full Inspection
We inspect all accessible ductwork in your attic, crawlspace, and unconditioned areas. We assess current insulation levels, identify air leaks, and document problem areas with photos.
Seal Air Leaks First
Before insulating, we seal all duct joints, seams, and connections with mastic sealant. Insulating over leaky ducts wastes the investment-sealing first ensures maximum efficiency.
Material Selection
We select the right insulation for your situation: fiberglass duct wrap for most applications, duct board for commercial projects, or spray foam for hard-to-reach areas. All materials meet Oregon energy code requirements.
Professional Installation
Our technicians wrap all exposed ducts with proper R-value insulation and secure with tape or mechanical fasteners. We install vapor barriers where needed to prevent condensation in Portland's humid climate.
Quality Verification
After installation, we verify complete coverage, check for gaps, and test airflow to ensure your system performs optimally. You receive documentation showing before/after conditions.
