Duct Sealing & Insulation
Leaky ducts are one of the most overlooked causes of high energy bills and uneven temperatures in Arizona homes. At Phoenix Insulation Solutions, our duct sealing and insulation services help homeowners take back control — sealing off wasted airflow, improving comfort, and boosting HVAC efficiency where it matters most. If your HVAC is running non-stop, your rooms feel uneven, or your attic ducts are exposed and unsealed, you're likely losing a significant amount of cooled air. Our team identifies problem areas, seals gaps, and insulates ductwork to lock in performance and deliver real, lasting results.
About the service
Ductwork runs through some of the hottest parts of your home — including attics, garages, and crawlspaces. If it's not properly sealed and insulated, your HVAC system works harder just to maintain the desired temperature.
Our duct sealing process involves identifying and sealing joints, leaks, and seams in the duct system using long-lasting mastic sealant. Then, we wrap and insulate the ducts with protective thermal material that reduces heat gain and loss. The result is a tighter, more efficient system that keeps air flowing exactly where it’s supposed to.
This service is especially useful in homes with older or flex duct systems, exposed runs in the attic, or areas with inconsistent airflow. Whether you're prepping for summer or just tired of hot spots and high bills, duct sealing and insulation is a smart step toward better comfort and savings.
- Seals leaky joints, gaps, and seams
- Reduces wasted air and energy
- Helps balance temperatures between rooms
- Lowers energy usage and HVAC strain
- Prevents dirt, debris, and allergens from entering your airflow
- Extends HVAC system lifespan and performance
What’s part of the service
Our service begins with a thorough inspection of your attic or crawlspace ductwork. We look for signs of air leakage, old or damaged insulation, disconnected runs, and temperature inconsistencies throughout the system.
Once identified, we seal all problem areas with commercial-grade mastic or foil-backed tape and reinforce key joints for durability. We then wrap the ducts in insulation rated for high-temperature areas and install vapor barriers if needed. Everything is done cleanly and with minimal disruption to your home.
- Full system evaluation
- Targeted air leak sealing
- Insulation wrapping for exposed duct runs
- Securing and reinforcing loose joints
- Optional airflow balancing and diagnostic testing
- Cleanup and walk-through at completion
In many homes, especially those built before modern code requirements, duct sealing alone can improve airflow and efficiency by 20% or more. Most homeowners feel the change almost instantly — cooler rooms, fewer hot zones, and less HVAC cycling.
why you should take the service
Think of your ductwork like the veins of your HVAC system — if they’re leaking, your system is working overtime. Sealing and insulating them is one of the most cost-effective upgrades you can make to boost efficiency, lower bills, and feel more comfortable in your space.
We’ve worked with homeowners all across the Valley who’ve seen major differences right away. One family in Scottsdale told us the temperature in their master bedroom finally matched the rest of the house — after years of trying everything else.
This service is especially powerful when paired with new insulation or HVAC tune-ups. It also helps improve indoor air quality by keeping out attic dust and allergens that often sneak through unsealed ductwork.
Whether your home is new or decades old, proper duct sealing and insulation makes sure your HVAC is working smarter — not harder. At Phoenix Insulation Solutions, we don’t just patch problems, we fix them right the first time — with results you’ll feel from the first day forward.
