Air Duct Replacement in San Gabriel Valley, CA

Transform your home’s airflow and eliminate damaged, outdated ductwork. Call Cypress Heating at 626-963-9810 for air duct replacement in San Gabriel Valley and nearby service areas.

While often overlooked, your home’s air ducts aren’t designed to last indefinitely. Over decades of use, they can accumulate significant wear and tear, becoming brittle, developing leaks, or even sustaining damage from pests or improper handling.

Neglecting regular maintenance, such as professional cleaning and inspections, can exacerbate these issues, leading to compromised airflow, reduced energy efficiency, and a potential decline in indoor air quality.

Replacing old or damaged ductwork offers a fresh start, ensuring optimal system performance and a healthier living space for years to come.

While professional air duct cleaning can resolve many issues affecting your home’s heating and cooling efficiency and indoor air quality, there are instances where replacing your air duct system proves to be the more cost-effective solution.

If you observe any of the following warning signs of air duct problems, schedule a system inspection, as these issues may indicate more significant problems than a standard cleaning can resolve.

  • Persistent and Loud Whistling Sounds – Noticeable and ongoing loud whistling noises emanating from air vents or within the air ducts.
  • Consistent Hot and Cold Spots – Persistent and significant temperature differences in various rooms of your home.
  • Strong, Lingering, or Recurring Foul Odors – Pervasive unpleasant smells that don’t dissipate after HVAC system use.
  • Extensive Visible Water Damage or Significant Mold/Mildew Growth – Large or widespread areas of water stains or mold/mildew contamination on or around ductwork.
  • Evidence of Significant Pest Infestation or Damage – Clear signs of a large or ongoing rodent or insect presence, or visible damage caused by them within the duct system.
  • Visibly Damaged Ductwork – Ducts that are clearly crooked, corroded, crushed, or have noticeable and substantial gaps or separations.

While the idea of DIY air vent or air duct replacement might seem appealing, it’s a task best left to certified HVAC technicians and heating and cooling specialists. These professionals possess years of dedicated education, specialized training, and hands-on experience in safely and correctly handling such complex systems. They also have access to the necessary tools and equipment to complete the job efficiently and securely.

Attempting to replace air ducts yourself carries significant risks. You could inadvertently damage your existing air duct system or even your home’s structure. Furthermore, improper installation can reduce the lifespan and efficiency of your entire heating and cooling system and potentially void its manufacturer’s warranty.

By entrusting your air duct replacement to qualified specialists, such as Cypress Air, you gain the assurance that the work will be performed professionally, efficiently, thoroughly, and correctly from the outset. This saves you valuable time, potential unexpected costs from errors, and unnecessary stress.

Your comfort is our priority. If something doesn’t feel right after your new ductwork is installed, contact us—we’ll make it right. Our service manager will follow up promptly to ensure you’re satisfied with the results.

Customer Reviews

Our Customers Love Our Service . . Here’s Why

  • The job was promptly done

    Cypress Heating & Air texted that the technician was on his way, including a photo of him. Joshua arrived on time and replaced the filter for the furnace; necessary after the big Eaton fire. He inspected the system and used the blue booties over his shoes.

  • Professional and on time

    Just had service from Joshua for my annual maintenance. He was very professional and did an excellent job. Would highly recommend him and Cypress. I have been a customer for over three years.
    Deborah in Glendora, CA

  • The technicians are great

    We have used Cypress for a few years now. We had an issue with our A/C and Joshua did a thorough inspection, was able to troubleshoot the issue and our A/C was up and going in no time. Great experience and service!
    James in Los Angeles, CA

  • Fast and efficient

    I had called the company that originally installed my mini-split system and they told me that I would have to wait for a month for an appointment. I called Cypress heating and they were here in two days. They took care of my issue and now I’m a loyal maintenance member.
    Luz in Arcadia

  • Made everything easy

    Got my second service from Cypress so they could check my heater as the winter cold sets in. Joshua did an excellent job. Came right in the time window agreed upon, gave me some good practical information on my unit, replaced the filter, and was able to make sure the system was running correctly.
    Pat in Monrovia, CA

  • Reliable and long-lasting

    Cypress Heating & Air has grown since I first meet Bob in 1994 and I see their trucks and vans everywhere. I still receive the same great service and look forward to continuing using Cypress Heating & Air for years to come.

Our 8-Step Air Duct Replacement Process

When it’s time to replace your home’s air duct system, you need a partner you can trust. At Cypress Air, we follow a 8-step process to ensure a high-quality replacement that maximizes your comfort and indoor air quality. Here’s what you can expect when you choose us:

STEP 1. Initial Consultation and Assessment – We will begin by thoroughly inspecting your existing ductwork and assessing your home’s heating and cooling needs to develop the best replacement plan. This includes performing load calculations to ensure the new ductwork is properly sized for your home.

STEP 2. System Design and Material Selection – Based on our assessment, we will design a new, efficient ductwork layout, considering airflow balance and zoning if required. We will also select the most appropriate duct materials and insulation levels based on local codes and the specific conditions of your home’s construction.

STEP 3. Permitting (If Required): If required by local regulations in our service area, we will handle the process of obtaining all necessary permits for the air duct replacement.

STEP 4. Preparation and Protection – We will carefully prepare the work area by protecting your floors and furniture from any dust or debris. To access the ductwork, we may need to create access points in walls or ceilings, and we will take precautions to minimize any disruption.

STEP 5. Removal of Old Ductwork – We will carefully dismantle and remove your existing ductwork system, including all sections and connections. We will also ensure proper and responsible disposal of the old materials.

STEP 6. Installation of New Ductwork – We will install the new ductwork according to the designed layout, ensuring secure connections and proper support using appropriate hangers. This includes connecting the new ducts to your HVAC unit (furnace/air handler) and all vents and registers. We will meticulously seal all seams and joints with industry-approved mastic sealant or foil tape to prevent air leaks and insulate ducts in unconditioned spaces to maximize energy efficiency and prevent condensation.

STEP 7. System Testing and Balancing – Once the new ductwork is fully installed, we will turn on your HVAC system to thoroughly test for proper airflow and any potential leaks. We will then adjust dampers and vents as needed to ensure balanced airflow throughout your entire home.

STEP 8. Cleanup and Restoration – Finally, we will ensure all work areas are completely cleaned, and any access points created in walls or ceilings will be properly repaired and patched. We will then explain the new system to you and answer any questions you may have.

By following these 8 steps, Cypress Air ensures a comprehensive and hassle-free air duct replacement experience. From the initial assessment to the final cleanup, contact us to have skilled HVAC professionals handle every stage with expertise!
