Signs Your Ductwork Needs Attention
Most Bay Area homes have ductwork issues that waste energy and reduce comfort. Here's how to tell if your ducts need professional service.
High Energy Bills
Leaky ducts waste heated or cooled air, forcing your system to run longer and drive up utility costs.
Uneven Room Temperatures
Some rooms too hot, others too cold? Leaky or disconnected ducts prevent proper airflow distribution.
Noisy Airflow
Whistling, rattling, or banging sounds from vents indicate loose connections, holes, or poor design.
Visible Damage
Visible tears, disconnected sections, or crushed ducts in attic or crawl space need immediate repair.
Poor Airflow in Certain Rooms
Weak airflow from vents or certain rooms never reaching desired temperature suggests duct sizing or routing problems.
Want Zone Control
Tired of heating/cooling the whole house when you only use certain rooms? Zoning systems give you room-by-room control.
Our Ductwork Services
Duct Sealing & Repair
Seal leaks, gaps, and disconnected sections using professional-grade mastic sealant and metal tape. Repair damaged ductwork to restore proper airflow and recover 20-30% of lost heating/cooling capacity.
- Identify and seal all leaks
- Reconnect disconnected ducts
- Fix damaged sections
- Reduce energy waste immediately
Duct Replacement & Design
When ducts are beyond repair or poorly designed, we replace sections or redesign the entire system for optimal airflow, efficiency, and comfort using Manual D calculations.
- Manual D duct design
- Properly sized ducts for your system
- Replace damaged or deteriorated ducts
- Fix uneven temperatures
Duct Insulation
Add or replace insulation on ducts in unconditioned spaces (attics, crawl spaces, garages) to prevent heat loss/gain and condensation that reduces efficiency.
- R-6 or R-8 insulation wrap
- Prevent condensation issues
- Reduce heat loss in winter
- Improve overall system efficiency
Zoning Systems
Install motorized dampers and zone controls to divide your home into separate heating/cooling zones. Control temperature room-by-room for maximum comfort and energy savings.
- Independent temperature control per zone
- Save energy by conditioning only occupied rooms
- Solve hot/cold room issues permanently
- Works with existing HVAC systems
Ductwork Challenges in Bay Area Homes
Bay Area homes—especially those built before 1980—face unique ductwork issues that waste energy and compromise comfort:
Crawl Space & Attic Ducts
The problem: Most Bay Area homes have ductwork in unconditioned crawl spaces or attics. Summer attic temps hit 130-150°F, winter crawls drop to 40-50°F. Your expensive heated/cooled air travels through these extreme environments before reaching living spaces.
Energy impact: Poorly insulated or uninsulated ducts in attics/crawls lose 25-40% of conditioned air to heat gain/loss. That's like leaving windows open while running AC or heat.
Solution: Proper duct insulation (R-6 to R-8) and sealing reduces loss to under 10%. Typical ROI: 2-4 years through lower energy bills.
Flex Duct Deterioration
Common in: Homes built 1970s-2000s. Flexible ductwork was cheaper to install than rigid metal ducts, but it doesn't last as long.
Failure modes: Inner liner tears or separates, insulation compresses and loses R-value, rodents chew holes (especially in crawl spaces), or ducts sag and kink reducing airflow by 50%+.
Lifespan: Quality flex duct: 15-20 years. Budget flex duct: 10-15 years. If your ducts are 20+ years old, expect multiple failures. Replacement is usually more cost-effective than continuous repairs.
Duct Leaks at Connections
Where leaks happen: Boot connections (where duct meets ceiling register), plenum connections (main trunk to branches), and anywhere ducts were joined with tape only (not mastic).
Why tape fails: Standard duct tape degrades in 5-10 years from heat cycling. It literally falls off. We routinely find disconnected ducts in attics blowing conditioned air into nowhere.
Professional sealing: Mastic sealant (UL 181 rated) + metal-backed foil tape creates permanent, airtight seal. We test with pressure gauges to verify leakage is under 10% of total airflow.
Undersized or Oversized Ducts
The issue: Many Bay Area tract homes (1960s-1990s) used cookie-cutter duct designs without proper Manual D calculations. Result: some rooms get too much airflow (noisy, wasteful), others get too little (never comfortable).
Symptoms you'll notice: Master bedroom always 5°F warmer than living room, loud rushing air at vents, or weak airflow in bedrooms farthest from air handler.
Fix: Professional duct redesign using Manual D calculations. We measure each room's heating/cooling needs and size branch ducts accordingly. Sometimes requires adding/removing branches or resizing main trunk.
Return Air Deficiency
Common mistake: Homes with central return (one return grille for entire house, usually in hallway). Modern HVAC systems need adequate return airflow to operate efficiently and avoid pressure imbalances.
Problems caused: Positive pressure in bedrooms forces conditioned air out through window/door gaps, negative pressure in main area pulls in unconditioned air from attic/crawl space, and reduced system efficiency (up to 30% loss).
Solution: Add return vents to bedrooms or install jump ducts (small ducts over doors to equalize pressure). Cost: $300-800 per room vs. continuous energy waste.
Asbestos-Wrapped Ducts (Pre-1980 Homes)
What you might have: Homes built before 1980 sometimes used asbestos-containing duct wrap for insulation. If intact and undisturbed, it's not an immediate hazard.
When it becomes a problem: During renovations, system replacements, or if wrap deteriorates and releases fibers. Any work involving asbestos requires licensed abatement contractors.
Our approach: We can visually identify likely asbestos wrap and recommend testing. If present, we coordinate with licensed abatement contractors for safe removal before ductwork replacement. Cost: $2,000-8,000 for abatement depending on scope.
Should You Repair or Replace Your Ductwork?
Repair Makes Sense When:
- ✓ Ducts are less than 15 years old
- ✓ Only one or two specific leaks/issues
- ✓ Ducts are properly sized for current system
- ✓ Insulation is intact and functional
- ✓ No major system changes planned
Typical repair cost: $500-2,000 for sealing and minor repairs
Replacement Makes More Sense When:
- ⚠ Ducts are 20+ years old with multiple issues
- ⚠ Replacing entire HVAC system (right-size ducts for new equipment)
- ⚠ Major home renovation or room additions
- ⚠ Persistent comfort issues despite repairs
- ⚠ Energy bills 40%+ higher than similar homes
Typical replacement cost: $3,500-8,000 for 1,500-2,500 sq ft home
