Gasline Mechanical was formed in 1994 by Founders John Anderson and Mike Osborne.  John and Mike both worked for B&B Heating and Air Conditioning, and they broke out on their own and formed Gasline Mechanical Inc. Within a few years, Mike was ready to move on to new things and left the company. John continued to build and grow the company from the late 1990s until now.

For the last 20 years, we have specialized in mixed-use, multi-family, industrial, and commercial work. During that time, we also completed large residential homes mainly for the contractors and developers we worked for. We have done the personal homes of some of the largest builders in the state.

Over the last few years during the pandemic, many of our largest clients have retired and moved on to new things. My two sons, Jake and Travis, have worked for Gasline for the last 10 years and are getting ready to assume the company’s reigns. We have now changed our focus to include the add on replacement sector of the HVAC Business. We are still doing some large commercial work actually replacing the equipment in some of the buildings we initially did 15-25 years ago. But our primary focus is now doing residential home replacement HVAC. The industry is evolving with technology and what we have to offer the homeowner is commercial-grade installations in homes with high-grade ductwork design normally not found in the residential sector. This approach of bringing commercial grade design for the home will increase reliability and efficiency not normally found in this market.

We specialize in zoned ducted systems, VRF ducted, and non-ducted installations. This allows for a quiet system and consistent temperature and comfort levels throughout the homes at greatly reduced operating costs. The photo library shows a commitment to quality installation at competitive pricing. We also do installations of warm floor systems typically coupled with forced air-zoned ducted systems for the ultimate comfort levels on multi-level homes or just the desire to have warm floors in areas that have hard surfaces, like bathrooms and kitchen areas. Slab on grade basements are also usually nice to have warm floor systems in addition to forced air systems.

In closing, we have had the pleasure of working for many of the largest companies in the Puget Sound Region such as Boeing, Microsoft, Goodman Reality, Connor Homes, and Murray Franklyn. We earned their trust by doing good work at a fair price and always making sure our systems operated the way they were designed to work. We do every job like it was for our own building or home. We don’t cut corners to become the low bidder and sacrifice the quality in doing so. We design and install our jobs up to a standard not down to a price. Many people have said that the work we do for the price we sell it for is a bargain.

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.

GASLINE was great to work with from start to finish. The decision was hard to put in A/C but now that I have, I haven’t regretted it one bit. Darren and the guys were easy to work with and if I hada question, it was answered. They took care of everything for US!! they were Professional, on time, the work was meticulous and complete. This is a quality company and the staff reflected that in their care for the work they performed!!

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.

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.

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.

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.
