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.

Common Issues

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?

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

I recently had maintenance done on my AC and furnace by ASI, and I wanted to highlight the great experience I had—especially with the technician, Jesus. From start to finish, Jesus was extremely professional, thorough, and clearly very knowledgeable about his work. He took the time to carefully service and clean both the AC and furnace, making sure everything was running properly and efficiently. What really stood out to me was his attention to detail—he didn’t rush the job and even went the extra mile by cleaning the outside of the unit, which I truly appreciated. On top of that, his customer service was outstanding. He was friendly, respectful, and took the time to explain what he was doing, which gave me a lot of confidence in the work being performed. Overall, I’m very satisfied with the service and the level of care provided. I will definitely be using ASI again in the future and would highly recommend requesting Jesus if you want the job done right.

After 21 years of faithful service our heater finally gave out. ASI came to the house and we went over a few options as to repair or replace. We elected the latter, and the very next morning ASI was on site with the new heater. Within 6 hours, Sebastian Garcia and his helper had the new heater installed. Sebastian spent some time explaining how to use the new thermostat, which is so much easier to use than the previous one. By the time they left the garage was clean and all the old stuff was carted away. A great job by an outstanding company. This morning I checked my old paperwork and found that the new heater and thermostat were only a couple of hundred dollars more than the ones I had purchased 21 years ago. ASI really offers good prices and great equipment. A special thanks to the service manager Joe Gondak for keeping in touch with the crew to insure there were no problems during the installation
FAQ

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.

Industry studies show that typical homes lose 20 to 30 percent of the air moving through the duct system to leaks, gaps, and poor connections. In San Diego that lost air is cooling or heating attics and crawlspaces instead of your living space. Sealing and repairing your ducts often pays for itself through lower energy bills and a more comfortable, evenly conditioned home.

Yes. Leaky ducts pull in dust, attic insulation particles, allergens, and humidity from unconditioned spaces and circulate them through your home. Sealing connections and replacing damaged sections keeps that contamination out and reduces the dust you see on surfaces. Properly sealed ductwork also helps your filtration system do its job, which is especially helpful for allergy and asthma sufferers.
