Residential Ductwork Services in Rancho Santa Fe, CA

Reviews

Efficient ductwork is essential to the performance of any cooling system, heat pump, or central HVAC system. In Rancho Santa Fe, CA, Major League Comfort Systems Heating and Air offers complete residential ductwork repair, ductwork maintenance, ductwork installation, and ductwork replacement services. Whether you’re dealing with uneven heating, poor air circulation, or are building a new home, our team of experienced HVAC professionals is here to help.

We design, install, and maintain air duct systems using industry best practices to ensure efficient airflow, lower energy bills, and improved indoor air quality. Our work extends to both modern and old house systems and supports central air, ductless mini-splits, and Geo Thermal systems.


Ductwork Repair Services

If your existing ductwork is damaged or leaking, your HVAC system will struggle to deliver cool air or cold air evenly. Leaky supply registers, disconnected branch ducts, or deteriorated sheet metal ducts can lead to energy waste and poor comfort. At Major League Comfort Systems Heating and Air, our ductwork repair services are designed to improve air distribution and extend the life of your HVAC system.

Common Ductwork Issues We Fix:

  • Energy loss due to gaps, holes, or unsealed butt joints
  • Uneven heating or cooling caused by disconnected branch lines
  • Loud airflow or cold air leaks in crawlspace areas
  • Obstructed air return or blocked trunk line
  • Poor indoor air quality due to contaminated or deteriorated flexible ducts

We repair all types of ductwork, including flex duct, flexible aluminum, and sheet metal ductwork. Our team also reseals A/C ducts using high-performance sealing products to reduce heat loss and increase energy efficiency.

If you're experiencing poor comfort in certain living spaces, rising energy bills, or inconsistent air from supply registers, it’s time to schedule a duct inspection.


Ductwork Maintenance Services

Regular ductwork inspections and cleaning help keep your air conditioning and central heating systems working properly. At Major League Comfort Systems Heating and Air, we provide annual ductwork maintenance services that support system performance and prolong the life of your HVAC unit.

Our Duct Maintenance Service Includes:

  • Inspection of all ductwork system components
  • Checking air return flow and supply register output
  • Tightening and sealing loose connections and butt joints
  • Cleaning flexible ducts and sheet metal ducts
  • Airflow testing and performance checks

Routine air duct sealing and cleaning not only improve airflow but also help eliminate dust buildup that can reduce air handler performance and indoor air quality.

For homeowners using heat pumps, ductless mini-splits, or central air, keeping the duct system clean and sealed is key to getting the most from your equipment in the long run.


Ductwork Installation Services

If you’re building a home or installing a new system, you need a trusted HVAC contractor for your ductwork installation. Our team at Major League Comfort Systems Heating and Air uses advanced tools, proper load calculation, and HVAC ductwork installation cost analysis to plan and install ducts that match your system and home design.

Our Ductwork Installation Process:

  1. Planning Stage – We measure square footage, consider ventilation system needs, and identify types of air and load demands.
  2. Design and Layout – We plan trunk lines, branch lines, air returns, and supply registers for balanced airflow.
  3. Installing Ductwork – We use different sizes of sheet metal ducts, flex duct, and flexible aluminum depending on the application.
  4. Testing – We inspect for air leaks and check the full air distribution system before activating your HVAC installation.

We follow current best practices to ensure every air duct installation meets the highest standards for comfort, safety, and energy efficiency. Whether it’s your first time installing ductwork or you're updating your current setup, our installation services are reliable and built to last.


Ductwork Replacement Services

Over time, duct systems wear out. If your home has old ducts, excessive energy loss, or poor air circulation, a full duct replacement may be the best option. Damaged or outdated ducts can no longer support the demands of a new system, especially if your HVAC has been upgraded.

At Major League Comfort Systems Heating and Air, we offer complete duct replacement services to improve performance and deliver better energy savings for your home.

Signs You Need New Ductwork:

  • Cracked or crushed flex duct in the crawlspace
  • Loud airflow and unusual noises
  • Mold, pests, or moisture damage in existing ducts
  • Poor airflow in rooms farthest from the air handler
  • High repair costs for patching leaks repeatedly

Why Replace Instead of Repair?

  • New sheet metal ductwork and flexible ducts reduce resistance and improve airflow.
  • Updated air duct systems reduce noise and increase comfort.
  • Replacing undersized or improperly installed ducts solves long-standing heat loss and airflow issues.

We’ll remove your existing ductwork, design a modern layout, and install new ductwork based on your home’s needs. We also ensure the installation process meets all local codes and standards.


What Affects Ductwork Cost?

Ductwork Cost Factors Include:

  • Total square-foot coverage and square footage of your home
  • Location of ducts (crawlspace, attic, walls)
  • Type of ductwork (flexible vs. sheet metal ducts)
  • Number of branch lines, return vents, and supply registers
  • System capacity and HVAC duct installation cost requirements

We provide up-front quotes and work with you to choose options that balance performance with budget. Whether you're adding ducts to a central air system or supporting air conditioner upgrades, we provide honest pricing and professional installation.
