Your **heating, ventilation, and air conditioning (HVAC)** system is made from a network of ducts, which work together to circulate air and deliver it to the heating and cooling components of your system. Air ducts are built to last, but the standard is to be replaced every 15 years. Poor ducts may cause losing up to 25% of the cold or hot air in your HVAC system. It decreases your HVAC system’s cost-efficiency and causes significant financial losses. In addition, damaged or exhausted air ducts influence the quality of the air inside your house or apartment because various outdoor air pollutant particles will freely spread through cracks and holes throughout your home. If you see any problems with the air ducts, you should contact an air duct repair or replacement service in Los Angeles to have the system checked. Global Green Solution is a highly reputed company that has been replacing air ducts for over a decade. With a high level of expertise, our HVAC technicians perform regular maintenance and emergency servicing of air ducts throughout LA. Call us now for free expert consultation and estimate of work.

Like any other utility system, [air ducts](https://ggshvac.com/air-duct-cleaning-los-angeles-ca/) have to be regularly tested, repaired, or even changed.

That’s why we provide free consultations to estimate your situation and decide whether your air ducts need to be replaced. You can contact us if: ### Your Air Duct system is visibly dented/punctured While we may not see air ducts during our daily life, they occasionally need replacement or repair to function correctly. Typically, one of the best places to observe your ductwork is in the attic, where it may not be fully concealed. If you’ve spotted dents or punctures anywhere in your system, you should immediately contact Global Green Solutions. Our technicians will check your ducts before deciding whether to change them or not. ### Your HVAC system is 10+ years old Many heating and cooling systems can last for decades with proper care and maintenance. Unfortunately, some system components, such as ductwork, are particularly susceptible to deterioration and damage. [Global Green Solution](https://ggshvac.com/) recommends regular checking (and potentially replacing) your ductwork every ten years. Book a visit of a technician now to ensure your [HVAC system](https://ggshvac.com/) operates properly and efficiently. ### Your HVAC system is no longer working properly Clogged or punctured ductwork can quickly lead to poor airflow and high energy bills. If your ductwork is damaged, it will place unnecessary strain on your entire HVAC system. When it seems things are not working well, it may be time for a **duct replacement**! Contact our manager for a free professional consultation on air duct checking or maintenance. ### Your HVAC system is producing noise or foul smells If your HVAC system suddenly begins emitting strange sounds or scents, it typically indicates that you have an underlying problem. If there are holes in your ductwork, it can produce noisy clangs and whistles as the air flows through your system. Similarly, your ducts may emit a foul smell if you have mold growth. Whatever the reason might be, you should reach out to a [reliable HVAC company](https://ggshvac.com/) to have your system inspected. Global Green Solutions provide services for duct repair and replacement in LA. [Call a technician for air duct replacement](https://ggshvac.com/contact/) ## Duct Replacement FAQs Can I replace my air ductwork on my own? Ductwork is a key element of your HVAC system. It is fragile and expensive. And even a tiny mistake may cause a significant decrease in the efficiency of your heating and air conditioning system. We recommend entrusting repair and air duct replacement to certified technicians from Global Green Solutions. What are the characteristics of good-working ducts? When your air ducts are well-insulated, clean, and regularly maintained, you will not need to change them. We recommend periodic expert checking of ducts if you decide to upgrade your HVAC system, even if your air ductwork is rather new. What season is best for Air Duct Replacement? Our experienced and certified technicians can replace your air ducts any time of the year. We recommend doing major replacements or installations during the warm months for your convenience. Call us to order air duct replacement services in LA. ## Repair, Seal or Replace Your Ducts? ### Repair One disconnected run, a torn section or a crushed elbow can be fixed on its own when the rest of the system is sound. ### Seal Leaky joints and seams in otherwise good ducts are sealed with mastic or approved tape, which keeps the conditioned air you pay for inside the ducts. ### Replace Worth it when the ducts are old and brittle, the insulation is falling off, several runs are damaged, the layout never delivered enough air to some rooms, or a new system needs different duct sizes than the old one. Our article [when to replace ductwork instead of repairing it](https://ggshvac.com/air-ducts/when-should-air-ducts-be-replaced-instead-of-repaired/) covers the signs in more depth. If the ducts are sound but dirty, [air duct cleaning](https://ggshvac.com/air-duct-cleaning-los-angeles-ca/) is the right service instead. ## What a Duct Replacement Involves ### 1. Inspection and measurements The existing runs, registers and returns are checked, and the rooms that are too hot or too cold are noted. ### 2. Design and sizing Duct sizes follow the airflow each room needs; the industry method is ACCA Manual D ([ACCA](https://www.acca.org/standards/technical-manuals/manual-d)). Undersized ducts can make a new system noisy or weak. ### 3. Removal and new ductwork The old ducts come out of the attic or crawl space and new insulated ducts go in, supported so they do not sag or kink. ### 4. Sealing every connection Joints, boots and the plenum connections are sealed. ### 5. Testing The project may need a duct leakage test: California's Title 24 energy code can require testing verified by a HERS rater when ducts are altered or replaced ([California Energy Commission](https://www.energy.ca.gov/programs-and-topics/programs/building-energy-efficiency-standards)). Ducts in a hot attic gain heat on hot summer afternoons, so a duct project is a good time to look at [attic insulation](https://ggshvac.com/attic-insulation/) and a [radiant barrier](https://ggshvac.com/radiant-barrier-installation/). Replacing the equipment too? Plan both together with [AC installation](https://ggshvac.com/ac-installation/) or [heat pump installation](https://ggshvac.com/heat-pump-installation/). ## What Affects the Cost of Air Duct Replacement? ### How much ductwork A few damaged runs or the whole system. ### Where the ducts run Attic and crawl space access, and the space to work in. ### Design changes New sizes or added returns to fix rooms that never got enough air. ### Insulation and sealing Insulated duct and sealed connections are part of a lasting job. ### Permit and testing Modifying heating and cooling systems in the City of Los Angeles needs a mechanical HVAC permit from [LADBS](https://dbs.lacity.gov/services/plan-review-permitting/mechanical-hvac-permits), and a duct leakage test may be required. ## Clients Love Global Green’s Air Ducts Replacement in LA Air Duct Replacement in Los Angeles | Global Green Solutions ### David T.
