MainStream Corporation - Berthoud, Colorado

Mainstream is knowledgeable and easy to work with. They provide excellent support and design. I had them provide air ventilation systems and components for a new house. Once the house was completed they provided the commissioning of the systems ensuring proper air flow through out the house. Cody is bright and efficient, yet thoughtful and thorough in explaining how the systems work. We are fortunate to have such an experienced and skilled person here in Colorado for assisting people with high energy efficient ventilation systems.

We are currently building own home and Cody has been instrumental in helping us with the details and building assembly options. I sent in my plans and the red lines returned were quite helpful. He helped to design the ventilation systems as well as help with many details and assemblies to consider with my budget.

Cody and Lisa's experience with building passive houses enables them to know what works, what doesn't, and what levels of insulation / air tightness, etc. need to be at to build a superior home. I highly recommend Cody, Lisa and Mainstream Corporation for all of your design and build needs when building a Passive (or near) House.

We are just beginning the process of getting Cody's help with designing our new Passive House. We intend you hire him to support our efforts throughout the process. Even though it's early in our working relationship I feel compelled to provide an early review because he has provided so much valuable information right from the beginning. If you are interested in building a High Performance Home start here with MainStream Corp and Cody Farmer.

Since we wrote this review we have spent many hours working with Cody & Lisa while designing our near Passive House. They have worked very hard to meet my very fast schedule and have been very patient with me throughout the process. Their expert advice and experience have been key to the success of our design. Without them I would still be in the design stage instead of pouring concrete today. Thank you Cody & Lisa.

Definitely exceeded my expectations!! Cody was an excellent resource from concept through commissioning. He has been easily accessible via phone and email and I needed that since I installed the system myself. He is an easy guy to work with and is a true expert on the topic. The Zehnder equipment and accessories are extremely high quality. The ERV has dramatically improved the air quality in our home. We don't wake up congested any more, smells dissipate quickly and even our radon levels have dropped. Working with Mainstream to design, purchase and install the ERV system was an excellent decision from every aspect!

Cody and his team are extremely knowledgeable and helpful and have helped me immensely in my high performance building development, Sol Lux Alpha.

Cody is great. Quick to respond and more helpful than the folks I spent thousands of dollars with. If choosing to go with Zehnder, which is a good product, you must go through Cody here at MainStream!

Incredibly knowledgeable, understanding, and helping folks do right by the planet. You won't find a better team than Cody and friends. I needed some high performance air sealing tape for a project and they had just what I needed and shipped it immediately. Their attention to the details that matter will give you confidence to take on the project of your dreams. Mainstream is becoming a go to for carbon neutral living projects supplies and consulting, and they live up to their reputation. Solid all the way around.

Working with Cody and Lisa and the Mainstream team was a game-changer for our DIY off-grid build. From air-sealing products and membranes to walking us through the components and installing our Zehnder ERV, they patiently journeyed alongside us until we crossed the finish line.

Right after we crossed that finish line, the Cameron Peak Fire raged through our mountain community. Unfortunately, seventeen of our neighbors lost their homes. Ash and smoke pummeled our house for weeks during the fire. We had to evacuate for eleven days at the height of the activity. I fully expected the place to have smoke and ash damage when we returned, but at least it was still standing. When I unlocked the door and walked in, instead, it smelled like a new house. The ERV did a fantastic job filtering out smoke and ash. The filters were black but still doing their job.

Our home is performing beyond our expectations and is by far the most comfortable home in which we've lived. We couldn't have built it without Mainstream!
