Duct Repair & Installation in San Diego County
The White Glove Guys. Attic ductwork repair, sealing, and new installation. Stop wasting energy and start breathing easier.
Your Ducts Are the Lifeline of Your HVAC System
The ductwork in your attic is responsible for delivering conditioned air to every room in your home. When ducts are leaking, disconnected, or poorly insulated, your HVAC system works overtime while your comfort suffers. Studies show that leaky ducts can waste 20–30% of the air your system produces—driving up energy bills and leaving rooms too hot or too cold.
The White Glove Guys specialize in attic ductwork for San Diego homes. Whether you need a repair to stop air loss, better insulation to protect against attic heat, or a complete duct installation for a new system or remodel, we do the job right. Every duct connection is properly sealed, insulated, and tested to ensure maximum airflow and efficiency.
Duct Problems We Fix Every Day
Your ductwork is out of sight in the attic, but these common problems have a big impact on your comfort and energy bills.
Leaking Duct Joints
Gaps and cracks at duct connections are the most common cause of energy waste. Conditioned air escapes into your attic instead of reaching your living spaces, forcing your HVAC system to run longer and harder.
Crushed or Disconnected Ducts
Flexible ducts in the attic can become kinked, crushed, or completely disconnected over time—especially after other work is done in the attic. This cuts off airflow to one or more rooms entirely.
Poor Duct Insulation
San Diego attics can reach 150°F in summer. Ducts without adequate insulation absorb that heat, delivering warm air instead of cool. Proper R-value insulation keeps conditioned air at the right temperature.
Uneven Airflow Between Rooms
If some rooms are comfortable while others are always too hot or too cold, the problem is often undersized ducts, improper layout, or damper issues. A duct assessment pinpoints exactly where airflow is restricted.
Excessive Dust & Allergens
Leaky ducts pull in attic dust, insulation fibers, and allergens, circulating them throughout your home. Sealing your ductwork improves indoor air quality and reduces allergy symptoms.

Repair or Replace? Choosing the Right Duct Solution
Depending on the age and condition of your ductwork, repair or full replacement may be the better option. We'll give you an honest recommendation.
Repair Your Ducts
Consider duct repair when these factors apply:
- Ductwork is less than 15 years old
- Damage is limited to a few connections or sections
- Ducts are properly sized for your system
- Insulation just needs upgrading
- Overall duct layout and routing is sound
Replace Your Ducts
Consider duct replacement when you notice:
- Ductwork is 20+ years old or deteriorating
- Multiple sections are crushed, torn, or disconnected
- Ducts are undersized for your current HVAC system
- Persistent mold or pest contamination inside ducts
- You're installing a new HVAC system and need proper sizing

Your Duct Repair & Installation Questions Answered
Common signs include rooms that won’t cool or heat properly, higher-than-expected energy bills, excessive dust in the home, and your HVAC system running constantly without reaching the set temperature. Our technicians can perform a duct inspection to identify and quantify any air loss.
Absolutely. Your HVAC system is only as good as the ducts that deliver the air. Leaky, crushed, or poorly insulated ducts force your AC or furnace to work much harder, increasing wear and tear, raising energy costs, and shortening the life of your equipment.
Most duct repairs—sealing leaks, reconnecting sections, and adding insulation—are completed in a single day. Full duct replacement or new installation for a whole home typically takes one to two days depending on the size and complexity of the layout.
If your ducts are relatively new and the damage is limited to a few areas, repair is usually the best value. For older ductwork with widespread deterioration, undersized runs, or contamination, replacement delivers better long-term comfort and efficiency. We’ll inspect your system and give you an honest recommendation.
Yes. Whether you’re adding a room, converting a garage, or building new, ASI designs and installs ductwork that integrates with your existing HVAC system. We handle load calculations, duct sizing, and proper routing to ensure balanced airflow throughout your home.
