Benefits of duct sealing services provided by Norco Air
Did you know that leaky ducts can waste up to 30% of the conditioned air your HVAC system produces? That means your heating and cooling system is working harder than it needs to — and you’re paying for air that never reaches the rooms you’re trying to heat or cool. Norco Air’s professional duct sealing service gives your home or business the decisive edge to:
- Significantly reduce energy waste and lower your monthly heating and cooling bills

Our duct sealing services stop energy waste and restore comfort to your entire space
Are your energy bills higher than they should be? Are some rooms always too hot in summer or too cold in winter no matter what you set the thermostat to? Leaky ductwork is one of the most common — and most overlooked — causes of HVAC inefficiency in homes and businesses. When conditioned air escapes through gaps and cracks in your ducts before it reaches its destination, your system runs longer, works harder, and costs you more every single month. Norco Air’s professional duct sealing service fixes that problem at the source — delivering real energy savings and real comfort improvement throughout your entire space.
Complete duct sealing solutions that save energy and improve comfort
Whether your ducts have minor leaks or major gaps, Norco Air has the tools and expertise to seal them properly. Here’s what we offer:
Duct Leak Detection
We use professional diagnostic tools to pressurize your duct system and locate every leak, gap, and crack — giving us a complete picture of where your conditioned air is escaping.
Manual Duct Sealing
We apply professional-grade mastic sealant and metal tape to seal gaps and leaks throughout your duct system — a long-lasting solution that outperforms standard duct tape every time.
Aeroseal Duct Sealing
For hard-to-reach leaks deep inside your duct system, we offer Aeroseal — an advanced sealing process that injects sealant particles into your ducts to seal leaks from the inside out.
Post-Sealing Efficiency Test
After sealing your ducts, we retest the system to measure exactly how much leakage has been eliminated — giving you clear, measurable proof of the improvement Norco Air has delivered.
Airflow Balancing
Sealing your ducts often reveals airflow imbalances that were previously masked by leaks. We test and balance your system after sealing to ensure every room receives the right amount of conditioned air.
Insulation Assessment
Sealing your ducts is only half the battle. We also assess your duct insulation to ensure conditioned air stays at the right temperature as it travels through unconditioned spaces like attics and crawl spaces.
