Ductwork Installation Services in Maryland & Washington, DC

Properly designed and installed ductwork is essential for achieving optimal HVAC performance. Poor duct design leads to uneven temperatures, higher energy bills, and premature wear on your heating and cooling systems. Our expert installers use precise load calculations and air distribution models to ensure your duct system delivers air efficiently throughout your entire home.

Common ductwork issues we resolve include:

• Improper sizing: Ducts that are too large can cause airflow stagnation, while ducts that are too narrow can increase static pressure and force your system to overwork.
• Air leaks and poor sealing: Even small gaps or holes can cause a loss of up to 30% of conditioned air, drastically reducing efficiency.
• Poor layout: Duct systems with sharp bends or long runs can restrict airflow and create inconsistent temperatures across your home.

Whether you’re building a new home, upgrading an old HVAC system, or replacing aging ducts, our team can design and install custom ductwork to maximize comfort and performance.

Custom Sheet Metal Fabrication

Unlike many contractors who rely on third-party suppliers, Michael Bonsby HVAC, Plumbing & Electrical performs all sheet metal fabrication in-house. This allows us to maintain total control over the quality, precision, and performance of your ductwork system.

Our skilled fabricators use advanced machinery to create customized ducts that fit your system perfectly—ensuring optimal airflow and long-lasting durability. Every piece of sheet metal is measured, cut, and assembled to meet the exact requirements of your HVAC equipment and home layout. With our in-house duct fabrication, you can trust that your installation will be both efficient and built to last.

Duct Sealing & Efficiency Optimization

Even if your ductwork is properly installed, leaks can develop over time due to age, vibration, or temperature fluctuations. Leaky ducts force your furnace or air conditioner to work harder, wasting energy and reducing system lifespan. Our duct sealing specialists use industry-leading methods to identify leaks, repair damaged sections, and restore your duct system to peak efficiency.

Our duct sealing process includes:

• Thorough inspection using airflow testing and pressure diagnostics
• Sealing of joints, seams, and connections with durable, non-toxic materials
• Insulation of exposed ducts to prevent heat loss or gain
• Verification testing to confirm improved performance

By improving the integrity of your duct system, you can experience lower utility bills, quieter operation, and consistent temperatures throughout your home.

Benefits of Professionally Installed Ductwork

Investing in high-quality ductwork installation offers benefits that go beyond just heating and cooling efficiency. With a properly designed and sealed duct system, you can enjoy:

• Energy savings: Reduce air loss and boost system efficiency by up to 30%.
• Improved indoor air quality: Prevent contaminants like dust and allergens from entering your air stream.
• Better comfort control: Maintain even temperatures and consistent airflow in every room.
