Duct Repair & Sealing in Sacramento, CA
Leaky ductwork wastes up to 30% of your conditioned air. If some rooms are always too hot or too cold, your ducts might be the problem.
Leaky Ducts Are Costing You Money
Up to 30% of the air your AC or furnace produces never reaches your rooms. It leaks out through gaps, cracks, and disconnected joints in your ductwork. For the average Sacramento home, that adds up to $200-$400 a year in wasted energy.
Most of your ductwork runs through the attic. In summer, Sacramento attics hit 140°F or higher. When cool air passes through un-insulated or damaged ducts in that heat, it warms up before it ever reaches your vents. You crank the thermostat lower, the system runs longer, and your electric bill climbs.
The fix is straightforward. Seal the leaks, insulate the runs, and your system stops working overtime. Most homeowners see the difference on their next energy bill.
Signs You Have Duct Problems
Duct problems don't always announce themselves. But if you know what to look for, the signs are hard to miss.
- Rooms that won't cool down in summer or heat up in winter, no matter how long the system runs
- Your house is dusty even though you clean regularly—leaky ducts pull in attic insulation and dirt
- Energy bills that keep climbing without explanation
- Rattling, whistling, or popping sounds from your vents or walls
- Visible duct damage, sagging, or disconnections in your attic or crawlspace
If two or more of these sound familiar, your ducts are probably costing you money. A pressure test will tell us exactly how much air you're losing and where.
How We Fix Duct Issues
We start with a full inspection. That means getting into your attic or crawlspace with a camera and checking every duct run. We pressure-test the system to measure exactly how much air is escaping.
Leaks get sealed with mastic—not duct tape. Despite the name, duct tape fails within months in Sacramento's heat. Mastic is a thick sealant that bonds permanently and handles temperature swings without cracking or peeling.
For attic runs, we insulate with R-8 wrap to keep conditioned air from cooking in the summer heat. Disconnected or crushed sections get repaired or replaced. After everything is sealed and insulated, we pressure-test again to confirm the fix.

Signs include uneven temperatures room to room, higher energy bills, dusty air from vents, and visible gaps or disconnections in exposed ductwork (attic or crawlspace).
Duct sealing typically costs $300 to $800. Duct repair or replacement of damaged sections ranges from $500 to $2,000 depending on accessibility and extent of damage.
If your ducts are in decent shape with just loose connections, sealing is cost-effective. If they’re crushed, disconnected, or over 20 years old, partial or full replacement is the better investment.
