Professional Ductwork Services in Portland: Repair, Sealing, Cleaning & Custom Fabrication for Better Efficiency

Your ductwork is the hidden circulatory system of your HVAC—quietly delivering heated or cooled air throughout your home. When it's leaky, dirty, poorly designed, or uninsulated, you lose up to 30% of conditioned air, face uneven temperatures, higher PGE or NW Natural bills, excessive dust buildup, and poorer indoor air quality from circulating allergens, mold spores, and wildfire smoke particles. In Portland's damp Pacific Northwest climate—with high humidity fostering condensation and mold, pollen/cottonwood clogging vents, and summer wildfire smoke settling fine particulates—quality ductwork is essential for comfort, health, and energy savings. At Efficiency Heating & Cooling, we provide complete professional ductwork services: custom in-house sheet metal fabrication, cleaning, sealing, repair, modification, installation, and insulation.

Why Ductwork Quality Matters in Portland Homes

Portland's variable weather amplifies duct problems: humidity causes condensation in uninsulated attic/crawlspace ducts, wildfire smoke infiltrates and lingers as fine particles, older homes (common in Irvington, Sellwood, or Alberta) often have undersized or leaky flex duct, and dust/pollen circulates rapidly if seals fail. Poor ductwork results in:

• Hot/cold spots and weak airflow from vents.

• Unexplained bill increases (leaks waste 20-30% of conditioned air).

• Faster dust accumulation and allergy flare-ups.

• Musty odors, whistling noises, or rattling from loose connections.

• Reduced HVAC lifespan from overworking the blower.

Our comprehensive services fix these issues head-on:

• Up to 30% Energy Savings — Sealed, balanced, insulated ducts minimize waste.

• Cleaner Indoor Air — Remove dust, allergens, mold, and smoke particulates.

• Consistent Comfort — Eliminate temperature swings with proper airflow and zoning.

• Longer System Life — Less strain on furnaces, heat pumps, and AC units.

We perform all custom sheet metal fabrication in-house for superior quality, faster turnaround, and precise fits—ideal for Portland's older homes, additions, or retrofits.

Our Complete Ductwork Services Tailored for Portland

We handle every aspect with local expertise:

• Duct Cleaning — EPA-compliant methods remove years of dust, allergens, mold spores, and wildfire smoke residue; before/after documentation; dryer vent cleaning available; recommended every 3-5 years (or 2-3 in high-smoke/humidity areas like Lake Oswego, West Linn, Happy Valley).

• Duct Sealing — Mastic sealant and metallic tape eliminate leaks; leak detection testing confirms results; stops up to 30% air loss.

• Duct Repair — Fix disconnected joints, damaged sections, deteriorating flex duct, or insulation failures; restore proper airflow.

• Duct Modifications & Custom Fabrication — System rebalancing, zone additions, custom fittings/transitions for better performance.

• Duct Installation — New construction, additions, or full system upgrades; sheet metal recommended for durability in damp climate.

• Duct Insulation — R-value optimization with vapor barriers for attics, crawlspaces, garages; prevents condensation and saves up to 20% on bills.

All work includes thorough inspection, detailed reporting, and compliance with Oregon energy codes.

Portland Ductwork FAQs

How often should ducts be cleaned in Portland?

Every 3-5 years generally; 2-3 years in areas with heavy wildfire smoke, high humidity, pets, or allergies.

How do I know if my ducts are leaking?

High bills, uneven temperatures, quick dust buildup, visible gaps—our techs use leakage testing for accuracy.

What's best for Portland's damp climate?

Sheet metal ducts resist moisture/mold better than flex; insulate unconditioned spaces to prevent condensation.

Does wildfire smoke affect ductwork?

Yes—fine particles settle and circulate; professional cleaning removes them and improves IAQ.

Do you handle commercial ductwork?

Yes—custom spiral fabrication, large-scale cleaning, and modifications for offices, retail, warehouses across the metro.

What about zoning or modifications?

We add zones, rebalance systems, and fabricate custom pieces for optimal airflow.

How much do duct services cost?

Varies by scope—free inspection provides exact upfront quote; sealing/repair often affordable with big savings.
