What Our Duct Repair & Sealing Service Includes

Duct Sealing

Duct sealing is the process of closing off leaks and gaps in your HVAC ductwork, which can account for significant energy loss. In Los Angeles homes, especially those with older construction or flexible ductwork, air leaks are common and can force your heating and cooling systems to work harder. We use professional-grade mastic sealants and specialized tapes to create airtight seals, preventing conditioned air from escaping into attics, crawl spaces, or wall cavities. This not only improves comfort but also directly reduces your energy consumption, a crucial factor with the fluctuating temperatures we see throughout Los Angeles.

Flex Duct Repair

Flexible ductwork, often used in tight or complex installations, is prone to tears, kinks, and punctures that compromise its integrity. If you notice reduced airflow from certain vents or hear hissing sounds, your flex ducts might be the culprit. Our technicians are skilled in repairing these delicate components, often using reinforced patching techniques and sealing them to prevent further damage and air loss. We understand that proper flex duct repair in Los Angeles ensures that the air you pay to condition actually reaches your living spaces.

Metal Duct Repair

Metal ductwork, while more durable than flex ducts, can suffer from cracks, holes from pests, or separation at joints. These issues can lead to substantial air leaks, especially in the extensive duct systems found in many Los Angeles residences. We meticulously inspect all metal duct seams, connections, and surfaces for damage. Our repair process involves patching holes with appropriate materials and sealing all joints and seams with high-temperature mastic, ensuring a durable and airtight fix that lasts.

Duct Insulation

Proper duct insulation is vital in Los Angeles to prevent temperature transfer between the air inside your ducts and the ambient temperature of unconditioned spaces like attics or garages. Uninsulated or poorly insulated ducts can lead to significant energy loss, making your HVAC system work overtime to maintain your desired temperature. We can assess your existing duct insulation and provide upgrades or repairs using high-quality insulation materials to ensure your conditioned air stays at the right temperature from your HVAC unit to your rooms.

Mastic Sealant

Mastic sealant is our go-to for creating robust, long-lasting seals on ductwork connections and penetrations. Unlike basic duct tape, mastic is a flexible, durable adhesive designed to withstand temperature fluctuations and prevent air leakage effectively. We apply mastic carefully to all joints, seams, and any areas where ducts connect to plenums or registers, ensuring a professional, airtight seal that contributes to improved indoor air quality and energy efficiency throughout your Los Angeles home.

Air Leak Repair

Any breach in your duct system constitutes an air leak, and these can manifest in various ways, from noticeable drafts to increased dust and allergen circulation. Our comprehensive air leak repair service involves a thorough inspection of your entire duct network to identify every point of leakage. We then employ the most effective repair methods, whether it’s patching a small hole, re-sealing a connection, or reinforcing a damaged section, to restore the integrity of your duct system and improve your home’s overall air quality.

Signs You Need Duct Repair & Sealing Right Now

  • Unexplained High Energy Bills: If your electricity or gas bills have spiked without a change in usage, leaky ducts in Los Angeles are a likely culprit. Air escaping through gaps means your HVAC system runs longer, consuming more energy to achieve the desired temperature.
  • Uneven Heating or Cooling: Rooms that are consistently too hot or too cold, despite your thermostat settings, often indicate an imbalance caused by duct leaks. The air isn’t reaching its intended destination efficiently, impacting comfort across your home.
  • Increased Dust and Allergens: Openings in your ductwork can draw in dust, pollen, and other airborne irritants from attics, crawl spaces, or wall cavities. If you’re noticing more dust settling or allergy symptoms worsening, your ducts may need immediate sealing.
  • Strange Noises from Vents: Hissing, whistling, or rattling sounds coming from your vents can signal air escaping through cracks or loose connections in your ductwork. These noises are often the first audible sign of a problem that needs attention.
  • Reduced Airflow from Vents: If you feel significantly less air coming from some vents compared to others, it’s a strong indicator of leaks or blockages within your duct system. This poor airflow affects both comfort and system efficiency.

Our Duct Repair & Sealing Process — Step by Step

  1. 1
    Initial Inspection and Diagnosis: We begin with a thorough visual inspection of your entire duct system, utilizing professional tools to pinpoint leaks, damage, and areas of concern. This diagnostic phase is crucial for understanding the full scope of the problem in your Los Angeles home.
  2. 2
    Air Leak Identification: Using specialized equipment like a smoke pen or digital manometer, we precisely locate every air leak, no matter how small. This ensures that no compromised areas are missed, leading to a truly sealed system.
  3. 3
    Duct Repair Execution: Based on the identified issues, we perform the necessary repairs. This might involve patching holes in metal ducts, reinforcing tears in flex ducts, or re-securing loose connections using professional-grade materials.
  4. 4
    Mastic Sealing Application: Once repairs are complete, we meticulously apply high-temperature mastic sealant to all joints, seams, and connections. This creates a durable, airtight barrier that prevents future air loss and enhances system efficiency.
  5. 5
    System Performance Verification: After sealing, we perform a follow-up inspection and, if necessary, a system test to confirm that airflow has improved and leaks have been eliminated. Our goal is to leave your ductwork operating as efficiently as possible.

How Much Does Duct Repair & Sealing Cost in Los Angeles?

More extensive issues, such as repairing multiple sections of flex duct or sealing large or hard-to-reach ductwork, could range from $1,000 to $3,500 or more.
