A Message from Garrett Lee
Hey, it's Garrett. I’m the owner of New Leaf Heat Pumps and a DIY'er who built a net-zero “big tiny” house for me and my family in Upstate NY. I am passionate about all things renewable energy and believe sharing that passion is essential for shaping a better future. As an advocate for the sustainable use of resources, I understand the importance of educating, inspiring, and helping others with their own unique and affordable renewable energy plan.
Our house is heated and cooled by a MRCOOL® DIY® series 3rd Generation heat pump (since replaced by the 4th Generation). There are no fossil fuels on site, no wood to split, no fuel oil smoke to breathe in, and it’s incredibly efficient. It took less than a day to install and is very easy to use. I was so pleased with these products that I installed them for my friends and family.
And now I’ve expanded, happy to share what’s worked for me and mine with you and yours.
