Your HVAC equipment can only perform as well as the ductwork that distributes conditioned air throughout your home. Undersized ducts restrict airflow and strain equipment. Oversized ducts waste energy and create comfort problems. Poorly designed layouts leave some rooms uncomfortable regardless of thermostat settings. Proper ductwork installation—based on engineering calculations rather than guesswork ensures every room receives the right amount of conditioned air.
Grande Air Solutions provides professional ductwork design and installation for homeowners throughout Pflugerville, Austin, Round Rock, Hutto, Cedar Park, Georgetown, and surrounding communities in Travis and Williamson counties. Whether you're building a new home, adding a room, replacing deteriorated ductwork, or correcting problems from a poor original installation, our licensed technicians deliver properly designed, expertly installed duct systems.
Founded by Isael Garcia in 2011, Grande Air Solutions has spent over 14 years installing ductwork in Central Texas homes. We've seen the difference proper design makes—rooms that were always uncomfortable suddenly staying at the right temperature, energy bills dropping, and HVAC systems lasting longer because they're not fighting inadequate ductwork.
New Home Construction Building a new home is the ideal time for properly designed ductwork. We work with builders and homeowners to design efficient duct systems that deliver comfort from day one.
Room Additions Adding a room to your home requires extending your duct system—and often assessing whether your current HVAC equipment can handle the additional load. We design additions that integrate properly with your existing system.
Garage Conversions Converting a garage to living space requires new ductwork to make the space comfortable. We can extend your existing system or design a dedicated solution depending on your situation.
Ductwork Replacement Old ductwork deteriorates over time. Flexible ducts get crushed and kinked, metal ducts rust and develop leaks, and connections fail. Replacement with properly designed new ductwork restores system performance.
Correcting Poor Installation Many homes have ductwork that was improperly designed or installed from the start. If rooms have always been uncomfortable despite your HVAC system working, redesigned ductwork may be the solution.
HVAC System Upgrades When upgrading to a larger or more efficient HVAC system, existing ductwork may need modification or replacement to handle different airflow requirements.
Zoning System Installation Adding zone control to your home requires ductwork modifications to accommodate dampers and additional thermostats. We design zoning systems that work with your existing layout.
Proper ductwork design follows established engineering principles—not guesswork:
Manual J Load Calculation We calculate heating and cooling loads for each room based on size, windows, insulation, orientation, and other factors. This determines how much conditioned air each room needs.
Manual D Duct Design Using load calculations, we design ductwork to deliver the right amount of air to each room. This includes sizing trunk lines and branches, determining optimal routing, and selecting appropriate fittings.
Equipment Matching Ductwork must match your HVAC equipment's airflow specifications. We verify compatibility and design ducts that allow your equipment to operate at peak efficiency.
Friction and Static Pressure Calculations We calculate pressure losses through the duct system to ensure adequate airflow reaches every room without straining your equipment.
Layout Optimization We design efficient routing that minimizes duct length, reduces fittings that restrict airflow, and ensures accessibility for future maintenance.
We install various ductwork types depending on your application and needs:
Sheet Metal Ducts The most durable and efficient option, sheet metal ducts provide smooth interior surfaces for optimal airflow, excellent longevity, and resistance to damage. Ideal for exposed installations, new construction, and situations demanding maximum performance.
Flexible Ducts Insulated flexible ductwork offers installation flexibility and lower cost. Best for branch runs to individual rooms where smooth airflow is maintained. We ensure proper support and avoid kinks that restrict airflow.
Duct Board Rigid fiberglass duct board provides good insulation value and can be appropriate for certain applications. We use duct board where it makes sense while ensuring proper air duct sealing and protection.
Insulated Ducts For ducts running through unconditioned spaces like attics, proper insulation is essential. We install appropriately insulated ductwork to prevent energy loss and condensation.
Return Plenums and Platforms We build proper return air systems including plenums, platforms, and filter housing to ensure adequate return airflow and easy filter access.
Step 1: Assessment and Planning We evaluate your needs, inspect existing conditions, and discuss options with you. For additions and replacements, we assess how new ductwork will integrate with your existing system.
Step 2: Design and Calculation We perform load calculations and design ductwork to deliver proper airflow throughout your home. You receive a detailed plan showing duct routing, sizing, and connections included in our duct service.
Step 3: Quote and Approval We provide detailed pricing with no hidden fees. Once approved, we schedule installation at your convenience.
Step 4: Preparation We protect your home, set up equipment, and prepare access points. For attic installations, we ensure safe working conditions.
Step 5: Installation Our licensed technicians install ductwork according to design specifications, ensuring proper support, sealing, and insulation. All connections are secured and sealed to prevent leaks.
Step 6: Testing and Balancing After installation, we test airflow to each room and balance the system for optimal performance. We verify that design specifications are met.
Step 7: Cleanup and Documentation We clean up thoroughly and provide documentation of your new duct system including layout and specifications.
Consider ductwork replacement if:
For new home construction, Grande Air Solutions works with builders and general contractors to design and install ductwork that meets project specifications and timelines:
Â
How long does ductwork installation take? Room additions typically take 1-2 days. Complete home ductwork replacement takes 2-4 days depending on home size and complexity. New construction timing coordinates with builder schedules.
Can my current HVAC system handle a room addition? It depends on your system's capacity and current load. We assess your existing equipment and calculate whether it can handle additional square footage. If not, we can discuss equipment upgrades or dedicated solutions for the new space.
What's the difference between flexible and rigid ductwork? Rigid sheet metal ducts offer better airflow, durability, and longevity. Flexible ducts cost less and offer installation flexibility but can restrict airflow if not installed properly. We typically use rigid ducts for main trunk lines and flexible ducts for branch runs to registers.
Will new ductwork make my home more comfortable? If your current ductwork is improperly sized, damaged, or poorly designed, new ductwork can dramatically improve comfort. Rooms that were always too hot or cold often become comfortable with properly designed replacement ductwork.
Do you install ductwork for mini-split systems? Mini-split systems are ductless—they don't require ductwork. If you're considering a mini-split for a room addition, it may eliminate the need for duct installation. We can discuss whether a ducted or ductless solution best fits your needs.
Can you add zones to my existing ductwork? Often yes, though it depends on your current duct design. Zoning requires dampers installed in ducts and additional thermostats. We can assess your system and explain what's involved in adding zones.
Should I replace ductwork when replacing my HVAC system? Not always, but it's worth evaluating. If your ductwork is old, damaged, or wasn't properly sized originally, replacing it along with your equipment ensures the new system performs optimally. We can assess your ductwork during system replacement quotes.
