Why we started and what we value as a contractor

Robert Hamerly, GreenSavers Principal

Robert Hamerly, GreenSavers Principal

Quality Matters

Hi, I’m Robert Hamerly. GreenSavers started at my kitchen table back in 2007. Before that, I spent most of my career in the trades, installing HVAC systems and building new homes in Oregon. 

Contractors are often incentivized to do projects as cheaply and quickly as possible. Of course it’s important to keep costs down, but we also need to value the efficiency and overall quality of the systems we’re installing. Our clients get better performance and save more over time with well-designed, energy efficient equipment at home. Society benefits from a better use of resources.


I created GreenSavers with the belief that contractors can do better. As a start, we offer every client a 100% satisfaction guarantee on our Portland, Oregon, heating and cooling services.


How we're different

GreenSavers stands out as a dedicated home performance contractor. That means we take a systems approach to home improvement. When we recommend an upgrade, like wall insulation, we work to understand how that upgrade effects other areas of your home, like air quality in your bedroom and moisture buildup in your bathroom.

We install energy efficient systems that perform well over time. Consider water heaters. We replace standard electric water heaters with Rheem heat pump water heaters, saving a family of 4 about $330 a year and $3,470 over the life of the system (Source: ENERGY STAR). We also like the Rheem water heater because its stainless steel elements prevent buildup and extend the designed lifespan by about 3-years. The same attention to detail applies to all of the systems we recommend, from environmentally responsible insulation to windows with a lifetime guarantee.

Our mission is to improve lives, inspire our team, and serve our communities by building in a better, more holistic way.


In January 2018, GreenSavers earned B Corporation Certification—the first dedicated home performance contractor in the world to do so. Certified by the nonprofit organization B Lab, B Corps are companies that meet the organization’s rigorous standards of transparency, accountability, and environmental and social performance. Essentially, B Corp certification is to business what USDA Organic certification is to milk, or what Fair Trade certification is to coffee beans.

Looking to the future, we're inspired to go beyond energy efficiency, helping clients live in homes with no net energy consumption. This means making homes highly efficient, then installing solar panels to offset any energy drawn from the grid. That's a future we can get behind.
