Why Duct Sealing Matters

Ductwork is the network of tubes and pipes that distributes conditioned air from your HVAC system throughout your property. When these ducts are not properly sealed, they can lead to a variety of issues, including:

  • Energy Loss: Leaky ducts allow conditioned air to escape, forcing your HVAC system to work harder to maintain the desired temperature.
  • Increased Utility Bills: As your HVAC system works overtime to compensate for the lost air, your energy consumption and utility bills will increase.
  • Uneven Temperatures: Poorly sealed ducts can result in inconsistent temperatures throughout your property, with some rooms feeling too hot or too cold.
  • Poor Indoor Air Quality: Leaks in your ductwork can allow dust, allergens, and other contaminants to enter your air supply, compromising your indoor air quality.

Our Duct Sealing Process

At Gasline Mechanical Inc., we follow a thorough process to ensure that your ducts are properly sealed for optimal performance. Our skilled technicians begin by conducting a comprehensive inspection of your ductwork to identify any leaks, gaps, or other issues. We use state-of-the-art diagnostic tools, such as air flow meters and pressure gauges, to pinpoint the exact location and severity of each problem.

Once we have a clear understanding of your duct system’s needs, we develop a customized sealing plan tailored to your specific property. Our team utilizes the latest techniques and materials, including mastic sealants and high-quality tapes, to effectively seal your ducts and prevent future leaks.

What our customers are saying
Customer Reviews

Many Years ago Gas line Mechanical installed our Heating system that was quite involved with 3 Floors. The Basement was left unfinished, But they installed a Duct system that could be extended for future use. After 18 Years I upgraded to a new High efficiency Furnace and Air conditioning. The new contractor admired the original installation and how well it was done. This prompted me to write these comments. I remember the original installer and how well they did their work. I believe the owners name was John. I want to thank him for a good Job they did all these years later.

A PSE inspector determined our 15-year-old furnace was emitting high levels of CO and capped off the gas line to our furnace. A big thanks to the inspector to catching that! John Anderson and his crew from Gasline Mechanical ordered and replaced the furnace within 5 days. We appreciate his fast response (especially considering the issues with shipping delays and the icy roads). This is the third time we’ve worked with Gasline Mechanical. They’ve been great to work with.

As the owner of Fusion Hot Yoga, located in Bothell, voted “Best yoga studio” in the “Best of Western Washington” contest, you can imagine how important “good” heat is to us! We heat our room to 105 degrees (!) and I’ll tell you what, heating a space to 105 that is built for over 100 people practicing yoga at once, well it’s simply not an easy task! Yet Gasline has managed to do it! We are currently running at 105 degrees due to Gasline’s ingenuity, and perseverance. I can’t recommend Darren and Steve enough! These guys are amazing. If you need to heat something, trust Gasline and trust Darren and Steve. These guys won’t let you down. I hesitate to endorse anybody, as I want to make sure It’s a valid and founded endorsement. And I take using my platform for endorsement very seriously… And in my experience Gasline now deserves my endorsement. So come feel the heat! And call Gasline for all your heating needs! If they can heat us, they can heat you! Thank you Steve and Darren! Jason Willey, owner Fusion Hot Yoga.

It has been my great pleasure to work with Gasline Mechanical on a number of projects. We have worked together for many years. I can count on their professionalism and teamwork to hold to schedule while providing a high quality finished product. From new construction to maintaining the equipment after our spaces are occupied, Gasline comes through with viable solutions to our most challenging HVAC needs. I look forward to continuing our working relationship and would highly recommend Gasline Mechanical.

I have worked with John Anderson and his employees at Gasline Mechanical for many years. Gasline can create heating, cooling and air-exchange systems in detail and to exact specifications from the drawing board to your construction site.

The Gasline design team can either quote & build from an engineered plan or create a design build system and are competitive in either arena. Once complete they have a very good warranty or maintenance team that can keep your equipment fine-tuned.

They understand how a system functions can either enhance or hamper the comfort of our buildings tenants. In addition to Gasline’s expertise in design, the install team has a great attitude and they clearly take pride in their work. I haveworked with many contractors and few can perform at Gasline’s level.You cannot make a better choice.
