Residential Clients

Insource Renewables works with clients in Maine seeking to reduce their heating bills, transition away from fossil fuels, and make their home more comfortable. We work in high-end, new construction projects to assist homeowners with their goals of achieving a net zero home and install heat pumps for low-income households that are striving to reduce their energy costs.

Whatever the setting, we take the time to listen to your individual goals and provide a high-quality solution that values your preferences, budget, and aesthetic.

Craftsmanship

The proper installation of a mini-split heat pump requires a strong understanding of refrigeration principles, electrical expertise, and general construction skills. With proper attention to detail, a mini-split heat pump can provide high efficiency heating and cooling for over a decade. When installed poorly, these units can leak refrigerant that increases the influence of climate change, pose a safety hazard due to concerns about combustion, require hundreds of dollars of avoidable servicing, and generally annoy their owner.

The key to ensuring a mini-split heat pump installation that minimizes long-term costs is attention to detail during the installation and commissioning process. The installation crews at Insource Renewables take great pride in their work and have the expertise needed to do it right the first time. We stand behind this claim by offering a 3-year labor warranty to our clients.

Commercial Clients

Insource Renewables serves a broad range of municipal commercial clients, including professional offices, restaurants, retail spaces, multifamily housing, nonprofit organizations and agricultural businesses. With an experienced staff of electricians and refrigeration professionals, we deliver the type of craftsmanship that communicates your commitment to quality to your clients and provides you with confidence in your new investment.

Our Installation Warranty

As a Fujitsu Elite contractor, we are able to offer a 12-year parts warranty for residential installations. While a parts warranty is reassuring, the labor associated with replacing a control board, a defective coil, or a failed compressor can be significant. We expect equipment to last and our customers often choose us because we value durable equipment and minimize surprises. Our company warranty assures that any labor required to resolve issues related to a parts failure or poor workmanship will be covered for 3 years.

  • Vaughan has professionally bridged the gap between being a contractor and being an advocate for Maine homeowners in their mission to save energy. He is not a ‘one size fits all’ in terms of efficiency and many times he has recommended our services over his own when looking at the types of challenges homeowners face when decreasing their carbon footprint.

  • Working with the Insource Renewables team was for me not only a satisfying experience but also encouraging about the renewable energy industry itself. These people were well-informed and articulate in their advice and planning on my project.

    They brought the fruits of both long experience with solar design and deep conviction about the importance of renewable energy in today’s world. In follow-up, they have been generous and good-natured in answering questions.

  • We contracted Insource Renewables to install a solar heater for our swimming pool and a cluster of home energy improvements. We were very pleased with the expertise, integrity, and work ethic of Vaughan Woodruff and his fine team.

    We were consistently informed of and/or consulted on scheduled activities and events throughout. At every juncture, Vaughan and his team were obviously guided by the principle of doing what is right for the customer.

    We have recommended to our friends and continue to unreservedly recommend Insource Renewables for any energy-related projects.

  • We are very happy with our new solar panels from Insource Renewables. It’s great that, now, our house is a power generation factory! Vaughan and the rest of the team are excellent, knowledgeable, friendly, proactive. Within 2 days of the start of the project, our meter was running backwards! It’s satisfying to make a small but real change in the severe climate issues that our planet is facing. I’m also really thankful that Vaughan connected us with the Greater Bangor Solarize program, which saved us over $2,000 on our installation! Vaughan provided us with many different options and answered so many questions that we had, until we found the solar project that was right for our family.

  • We discovered Insource Renewables (and Backyard Buildings in Unity) this Spring and were immediately taken with the concept of the “solar shed.” We knew we needed to build or buy a shed for some extra outdoor storage, and I’d always wanted to go solar at our house, so this made perfect sense!

    Matt, Vaughan, and the whole team at Insource were excellent to work with, answered all our questions, and made sure everything came together on this project. We are excited to be building out the inside of our shed while knowing we are making power every day just by having this system in our back yard.

    Great job all!

  • When our heat pump had electrical issues, there are a couple of ways that this event could have gone. Insource could have blamed the manufacturer, basically come back and continued to tweak the unit, or – worse yet – not been terribly responsive overall. I can’t tell you how good and stress free it has felt to know that you guys have put the customer first and have done your absolute best in the matter.
    We are very grateful.
