Your energy bills drop. Not by a few dollars, but by up to 30% when leaky, poorly installed ductwork gets replaced with a system that’s sealed, insulated, and sized correctly for your home.
Every room hits the same temperature. No more second-floor bedrooms that bake in summer while the downstairs stays cool. No cold spots in winter. Just consistent comfort in every corner of your house.
Your air gets cleaner. Sealed ductwork keeps dust, pollen, and outdoor contaminants from sneaking into your system and circulating through your home. That means fewer allergens, less irritation, and air that doesn’t make you wonder what you’re breathing.
Your HVAC system stops working so hard. When air flows the way it’s supposed to, your equipment doesn’t strain to push conditioned air through kinked, crushed, or disconnected ducts. That means fewer repairs, longer system life, and less money spent keeping things running.
Texas Air Repair is a -owned HVAC company with over 20 years of experience serving homeowners across San Antonio, Fair Oaks Ranch, and the surrounding Hill Country. We’ve installed ductwork in hundreds of homes—from sprawling ranch-style properties to multi-level builds with bonus rooms and extended wings.
We know Fair Oaks Ranch homes. The large floor plans, the high ceilings, the challenge of keeping 3,000+ square feet comfortable when Texas humidity regularly pushes past 70% in summer. We’ve seen what happens when ductwork isn’t sized right or when installers cut corners on sealing and insulation.
Our team includes certified technicians who understand Texas climate demands and local building codes. We don’t subcontract installations. We handle everything from permits to final inspection, and we stand behind our work with comprehensive warranties on parts and labor.
We start with an assessment of your home. That means measuring your square footage, checking your existing HVAC capacity, and identifying problem areas where airflow is uneven or energy is being wasted. We’re looking at your current duct layout, insulation levels, and whether your system is properly balanced for your floor plan.
Next, we design a ductwork system that fits your home’s specific needs. For Fair Oaks Ranch properties with extended layouts or multiple levels, that often means creating zones that allow better temperature control. We calculate the right duct sizes, plan the routing to minimize bends and restrictions, and select materials that resist Texas heat and humidity—typically galvanized steel or aluminum with proper insulation rated for our climate.
Installation takes one to three days depending on your home’s size. We pull permits, remove old ductwork if needed, and install the new system with attention to sealing every joint and connection. Leaky ducts are one of the biggest energy wasters in any home, so we use mastic sealant and metal-backed tape—not the cloth duct tape that fails in attics.
Once the system is in, we test airflow at every register, check for leaks using pressure testing equipment, and make sure your HVAC system is delivering the right amount of conditioned air to each room. You’ll notice the difference immediately—balanced temperatures, quieter operation, and air that feels cleaner.

You’re getting a complete system designed for your home’s layout and Texas weather. That includes properly sized ductwork—not undersized runs that restrict airflow or oversized ducts that waste energy. We match duct dimensions to your HVAC system’s capacity and your home’s heating and cooling load.
Insulation matters more in Texas than most places. Attics here regularly hit 140°F in summer, and uninsulated ducts lose a massive amount of conditioned air before it ever reaches your living spaces. We install ductwork with insulation rated for Texas heat, typically R-6 or R-8, which keeps cool air cool and prevents condensation that leads to mold growth in humid conditions.
Every joint gets sealed. We’re talking mastic sealant and metal-backed tape at every connection point, because even small leaks add up to major energy loss. The Department of Energy estimates that leaky ducts can lower your system’s efficiency by 30%, and in Fair Oaks Ranch’s climate, that’s a lot of wasted cooling capacity.
You also get proper dampers and balancing. Homes with large floor plans or multiple levels need airflow control to keep temperatures even. We install dampers that let you adjust air distribution and balance the system so every room gets the right amount of conditioned air.
Final testing and inspection are part of the job. We don’t consider an installation complete until we’ve pressure-tested the system, verified airflow at every register, and confirmed that your HVAC equipment is operating efficiently with the new ductwork.
Most residential duct installations take one to three days depending on your home’s size and layout. A single-story home under 2,500 square feet typically takes one to two days. Larger homes with multiple levels, bonus rooms, or complex floor plans common in Fair Oaks Ranch can take three days or slightly longer.
The timeline includes removing old ductwork if you’re replacing an existing system, installing new runs, sealing all connections, adding insulation, and testing the system for leaks and proper airflow. We’re not rushing through the job—every joint needs to be sealed correctly, and the system needs to be balanced so each room gets the right amount of air.
We work efficiently and keep disruption to a minimum. Most of the work happens in your attic or crawlspace, not in your living areas. You’ll have full use of your home during installation, and we clean up thoroughly when we’re done.
Galvanized steel and aluminum ductwork hold up best in Texas conditions. Both materials resist corrosion from humidity, maintain their shape in extreme attic temperatures, and last 25 to 30 years when properly installed and maintained.
Flexible ductwork is cheaper and faster to install, but it’s not ideal for Texas attics. Flex duct can sag in heat, kink easily, restrict airflow, and deteriorate faster than rigid metal ducts. We use flex duct only for short runs where rigid ductwork isn’t practical—never for main trunk lines or long runs where airflow efficiency matters most.
Insulation is just as important as the duct material itself. We wrap all ductwork with insulation rated R-6 or higher to prevent heat gain in summer and heat loss in winter. In Fair Oaks Ranch, where attic temperatures regularly exceed 130°F, uninsulated ducts waste a huge amount of energy. Proper insulation also prevents condensation that leads to mold growth when cool air moves through ducts in a hot, humid attic space.
The Department of Energy estimates that sealing and insulating ducts can reduce heating and cooling costs by up to 30%. In a Fair Oaks Ranch home where you’re running AC heavily from May through September, that can mean savings of $50 to $150 per month during peak summer.
The biggest energy waste comes from leaky duct connections. When conditioned air escapes into your attic or crawlspace before reaching your living areas, your HVAC system has to work longer and harder to maintain comfortable temperatures. That means higher electric bills and more wear on your equipment.
Properly sized ductwork also improves efficiency. Undersized ducts restrict airflow and force your system to run longer cycles. Oversized ducts reduce air velocity, which means less effective heating and cooling. When ductwork is sized correctly for your home’s square footage and your HVAC system’s capacity, air moves efficiently and your equipment operates at peak performance.
You’ll also see savings from fewer repairs. When your HVAC system doesn’t have to strain against poor airflow or work overtime to compensate for leaky ducts, it lasts longer and breaks down less often.
Yes, if the problem is caused by poor duct design, leaks, or improper airflow balance. Many Fair Oaks Ranch homes have temperature issues because the original ductwork wasn’t designed for the home’s layout—especially in houses with additions, finished bonus rooms, or extended floor plans.
Uneven temperatures usually happen when some rooms get too much airflow and others don’t get enough. That’s often a result of improperly sized ducts, too many bends and restrictions in the duct runs, or a lack of dampers to control air distribution. When we install new ductwork, we calculate the right duct sizes for each room based on square footage and heat load, and we install balancing dampers that let us fine-tune airflow.
Leaky ducts are another common cause. If air is escaping through gaps and poorly sealed joints, rooms at the end of long duct runs won’t receive enough conditioned air. Sealing every connection eliminates that waste and ensures air reaches every register at the right volume.
In multi-story homes, hot air rises and upper levels hold heat longer. Properly designed ductwork accounts for that by delivering more conditioned air to upstairs rooms. We also recommend zoning systems for larger homes, which let you control temperatures independently on different floors or in different areas of the house.
Absolutely. Sealed, properly installed ductwork keeps dust, pollen, and outdoor contaminants from entering your HVAC system and circulating through your home. Old or leaky ducts pull in attic dust, insulation particles, and allergens every time your system runs.
Texas humidity creates additional air quality challenges. When ducts aren’t sealed and insulated correctly, condensation forms inside the ducts. That moisture creates an environment where mold and bacteria thrive. Once mold takes hold in your ductwork, it releases spores into your air every time your system runs, triggering allergies and respiratory irritation.
New ductwork eliminates those entry points. We seal every joint with mastic and metal-backed tape, so the only air moving through your system is air that’s been filtered through your HVAC unit. That means fewer allergens, less dust settling on your furniture, and cleaner air for your family to breathe.
Proper insulation also prevents condensation, which stops mold growth before it starts. In Fair Oaks Ranch’s humid climate, that’s critical for maintaining healthy indoor air. Combine new ductwork with regular filter changes and periodic duct cleaning, and you’ll notice a significant improvement in air quality.
Yes. We pull all necessary permits and handle inspections as part of our installation service. Fair Oaks Ranch and Bexar County have specific building codes for HVAC work, and any ductwork installation or major modification requires a permit and final inspection.
Permits aren’t just red tape—they ensure the work meets safety standards and local codes. That protects you as the homeowner and ensures your system is installed correctly. If you ever sell your home, unpermitted HVAC work can create problems during the sale process and potentially affect your home’s value.
We handle the entire permit process from start to finish. That includes submitting plans, scheduling inspections, and making sure everything passes on the first try. You don’t have to deal with paperwork or coordinate with inspectors—we take care of it all.
Once the installation is complete and the system passes inspection, you’ll receive documentation showing the work was done to code. That gives you peace of mind and protects your investment in your home’s comfort system.
