About Us

Integrity Services of Maine is a family-owned company based in Poland Spring. The company was started in 2017 by Bill Bouchard, who has over 20+ years of experience in the field. Although there are many HVAC companies in Southern Maine, Bill saw a need and wanted to provide a higher level of professional, ethical, and quality service to the greater L/A area.

In 2021, ISM was able to relocate their shop in Poland to their new shop on Minot Avenue in Auburn

We have a passion and drive for the work we do. We perform installations and repairs on refrigeration, heating and cooling systems. Our niche is cutting-edge high efficiency equipment. We work with both commercial and residential customers. Our goal is to leave a lasting impression with all our clients, no matter the size of the job.

We are very involved in our local communities. Check out our Instagram and Facebook page to see what we’ve been up to lately!
