Your home’s ductwork system plays a key role in distributing cool air and heat throughout your living spaces. If your ducts are old, damaged, or poorly installed, it can lead to energy loss, uneven heating, and poor indoor air quality. At Major League Comfort Systems Heating and Air, we provide full-service residential ductwork repair, maintenance, installation, and replacement across Carlsbad, CA, and surrounding areas.

Our experienced HVAC professionals understand how to optimize airflow, improve comfort, and reduce energy bills with properly designed and installed duct systems. Whether you’re building a new system, dealing with damaged ducts, or upgrading your central HVAC system, we can help.


Residential Ductwork Repair Services

Damaged or leaking existing ductwork can reduce your system’s energy efficiency and impact indoor comfort. Leaks at the air return, joints, or supply registers can allow conditioned air to escape into the crawlspace or attic, forcing your AC unit or heat pump to work harder.

Common Signs You Need Ductwork Repair:

  • Cold air or hot air not reaching certain rooms
  • Higher-than-usual energy bills
  • Musty odors coming from vents
  • Rattling or whistling sounds during system operation
  • Excessive dust buildup in your home
  • Temperature differences between rooms
  • Poor airflow from branch ducts or main trunk lines

We inspect for leaks, disconnected joints, crushed sections, and other damage, using best practices in sealing and repairing to restore full function.

What We Repair:

  • Gaps in flex duct and sheet metal ducts
  • Disconnected or damaged branch lines
  • Improperly sealed butt joints and connections
  • Airflow issues related to poor air duct sealing
  • Insulation problems in A/C ducts

Our team ensures your system runs efficiently and supports better air circulation and comfort throughout your home.


Residential Ductwork Maintenance Services

Even well-installed ducts need routine attention. Over time, dust, debris, and insulation wear can reduce airflow and affect the performance of your HVAC unit. Our ductwork maintenance services focus on inspecting your ductwork system, cleaning key components, and ensuring peak airflow.

Key Maintenance Tasks:

  • Check for and seal air leaks
  • Inspect duct supports and insulation
  • Evaluate performance of return vents and supply registers
  • Measure static pressure to identify airflow issues
  • Clean ducts to improve indoor air quality and reduce allergens
  • Confirm connections at air handler and plenums are secure

We recommend scheduling duct inspections annually or as part of your broader HVAC maintenance plan.

Benefits of Duct Maintenance:

  • Improved energy savings
  • Better temperature control and air distribution
  • Reduced wear on your cooling system
  • Lower long-term HVAC ductwork installation cost
  • Enhanced comfort in your old house or newer home

Residential Ductwork Installation Services

If you're building a new home or adding onto your property, duct work installation is one of the most important steps in setting up your central HVAC system. At Major League Comfort Systems Heating and Air, we provide professional air duct installation that matches your home’s layout and heating/cooling requirements.

We begin with a full load calculation to determine your cooling system and airflow needs based on square footage, insulation, and room layout. This planning stage helps us design the right types of ductwork and ensure efficient performance from day one.

What Our Installation Includes:

  • Design and layout of branch ducts and main trunk line
  • Installation of flex duct, sheet metal ductwork, or flexible aluminum, depending on your home’s needs
  • Proper sizing of ducts to avoid airflow restrictions
  • Secure fittings using butt joint connections and sealants
  • Correct placement of return vents and supply registers
  • Integration with your air handler, heat pumps, or Geo Thermal system

We also work with ductless mini-split systems if your home doesn’t require traditional ducting. Our goal is to give you long-lasting performance and energy efficiency from a properly balanced ductwork system.

Why Proper Installation Matters:

  • Prevents heat loss through ducts
  • Ensures balanced airflow to all rooms
  • Reduces strain on your HVAC equipment
  • Avoids early replacement or costly fixes
  • Supports comfort and reliable operation in the long run

Residential Ductwork Replacement Services

Older homes often have aging, undersized, or poorly insulated existing ducts. If your current system can’t keep up or has been patched too many times, a full duct replacement may be the most cost-effective solution.

At Major League Comfort Systems Heating and Air, we assess your current system and offer a complete ductwork replacement with newer materials that meet modern efficiency standards. We use different sizes and designs to ensure airflow reaches every room evenly.

When to Consider New Ductwork:

  • Visible signs of deterioration or corrosion in sheet metal ducts
  • Constant temperature differences between rooms
  • Poor airflow even after repairs or cleaning
  • Mold growth or pest damage in ducts
  • High static pressure and short-cycling HVAC units
  • Planning to install a new HVAC system or relocate your air conditioning setup

Our replacement service includes safe removal of old ducts, full system redesign if needed, and expert HVAC installation to ensure performance and compliance with code.

Duct Replacement Options:

  • Full sheet metal ductwork with upgraded insulation
  • High-quality flexible ducts for tight spaces
  • Zoned systems for multi-level homes
  • New air return configurations to increase airflow

Replacing your ducts can deliver noticeable improvements in energy consumption, system lifespan, and day-to-day comfort.
