Frequently Asked Questions
Why Are Leaky Ducts a Problem in Coastal Areas?
Leaky ducts are a significant problem in coastal regions, particularly in areas with high humidity and corrosive salt air. Holes and gaps in the ductwork allow humid, unconditioned air from attics or crawl spaces to enter, increasing moisture levels inside your home. This elevated humidity can create an environment conducive to mold and mildew growth throughout your duct system. Furthermore, the salt in the coastal air accelerates the corrosion of metallic duct components, causing any existing damage to worsen rapidly. This combination of factors dramatically reduces HVAC efficiency and severely compromises indoor air quality.
How Do You Find Leaks in My Ductwork?
Our certified technicians use a multi-step process to accurately locate leaks in your ductwork. We begin with a thorough visual inspection of all accessible ductwork in the attic, basement, and crawl spaces, looking for obvious gaps or disconnections. We may also use specialized equipment, like a duct testing blower door, to pressurize the system and measure the amount of conditioned air being lost. Smoke tests, where a harmless smoke is introduced into the system, allow us to visually trace where air is escaping from the ducts. This precise diagnostic work ensures that no hidden leaks are overlooked before the sealing process begins.
How Long Does the Duct Sealing Last?
Professional duct sealing, when done using high-quality materials, is a durable solution designed to last for many years, often for the remaining lifespan of the ductwork itself. We use professional-grade sealants, like mastic or aerosol sealant (Aeroseal), which form a permanent, airtight bond at the leak points. Unlike standard duct tape, these sealants are specifically engineered to withstand temperature fluctuations and remain flexible without cracking or peeling. Many advanced sealing technologies come with a warranty, guaranteeing their effectiveness for at least 10 years or more. This long-lasting repair ensures consistent energy savings and comfort.
When Is Duct Replacement Necessary Instead of Repair?
Duct replacement becomes necessary when the existing ductwork is extensively damaged, aged beyond repair, or severely contaminated. If the ducts are over 15 to 20 years old and exhibit signs of significant physical deterioration, such as tears or widespread corrosion, repair can often be inefficient and costly. Extensive mold contamination that cannot be fully remediated through cleaning also necessitates replacement to ensure healthy indoor air quality. Additionally, replacement is recommended if the current duct design is fundamentally flawed or improperly sized for your HVAC system, leading to chronic performance issues. Replacement ensures a clean, correctly sized, and properly sealed system for optimal performance.
Can I Repair My Leaky Ducts on My Own?
While you can handle very minor, easily accessible leaks, extensive or hidden duct repair should be left to professionals. DIY attempts often rely on materials like common duct tape, which is ineffective and quickly fails due to heat and humidity. The most significant leaks are often hidden in inaccessible areas, such as behind walls or deep within the attic insulation. Additionally, DIY methods cannot accurately measure the total air leakage, so you cannot confirm the repair was successful. Professional sealing techniques and diagnostic testing ensure all leaks are found, properly sealed with durable materials, and confirmed to meet efficiency standards.
How Long Does a Professional Duct Repair Take?
The duration of a professional duct repair job typically depends on the total extent of the required work, but most residential sealing projects take between half a day and a full day. Simple repairs, such as sealing a few disconnected joints in an accessible attic, can be completed in just a few hours. A comprehensive sealing process using advanced aerosol technology, which involves system preparation, pressurization, sealing, and final performance testing, may take approximately four to eight hours. For extensive damage or full duct replacement, the job will take longer and the technician will provide a detailed time estimate upfront.
