Duct-EZ HVAC Sealing

Duct-EZ HVAC Sealing

What Is Duct-EZ HVAC Sealing?

  • A high-performance, interior duct sealing solution designed to stop leaks from the inside out.
  • Duct leakage issues are typically identified through duct blaster testing, which measures how much conditioned air is escaping the duct system.
  • Using a safe, pressurized spray sealant, we seal joints, seams, and holes that would compromise HVAC system performance.
  • This advanced method is perfect for both new builds and retrofit projects.

Why Duct-EZ HVAC Sealing Matter

Most HVAC systems lose 20%–30% of conditioned air due to leaky ducts, which means your home or building wastes energy and struggles to maintain comfort. Poorly sealed ductwork leads to:

  • Higher energy bills
  • Uneven heating or cooling
  • Poor air quality and humidity issues
  • Failing blower door or duct blaster tests
  • Disqualification from energy rebates

By choosing Duct-EZ, you ensure your ducts meet energy code and pass performance inspections—without tearing down walls. Proper duct sealing also supports equipment sizing used in Manual J/DS HVAC calculation.

Benefits of Duct-EZ HVAC Sealing

  • Seals from the inside—no invasive demolition
  • Improves airflow and HVAC efficiency
  • Reduces energy waste and utility bills
  • Helps pass code-required duct leakage tests
  • Boosts indoor air quality by minimizing pollutants

The owner of the company is super knowledgeable and responsive. While other companies told me I didn’t qualify for rebates, Josh told me otherwise and guided me through the process. In the end he was right, I got a sizable rebate. I highly recommend working with them and would definitely use them again for future projects.

★★★★★ 10/10 As a builder and real estate developer, I work with a lot of consultants, and JB’s Home Energy stands out. Josh and his team supported my six-unit multifamily new construction project from the very beginning, getting involved during design and helping us evaluate and compare different energy and compliance options before we ever broke ground. They were reliable, stayed on schedule, and communicated clearly throughout the process. The blower door testing at the end was seamless and executed flawlessly. I would not hesitate to work with Josh’s team again and would recommend them without reservation.

We enjoyed working with JBHE and Tacoma Energy over the past year to obtain our maximum MassSave rebates. They were professional, timely, pleasant, and responsible. The home energy installation, assessment, and rebate process in Massachusetts can be complex, and these folks always made it clear and easy for us to navigate. I would highly recommend Josh and Robin! Marc Draisen Roslindale, Massachusetts
