I just wanted to let you know how much we appreciated the service and support that you and your company provided. Times like that can be unsettling and uncomfortable, and Encon made the short period we were without heat very manageable.

If I could rate this experience from 1-10, 10 being the best, I would rate my experience an 11. Please send my thanks and gratitude to all.

With no experience, I started working for ENCON over twenty years ago. Because of the dedicated and hard-working people I’ve met here over the years, I was trained in house and was able to grow as an employee. We work very hard every day, but the owners and managers here show that you’re appreciated. As big as the company is today, it still feels like a family.

ENCON is an extremely family-friendly company. While some companies pay lip service to create a supportive environment for working mothers, ENCON delivers. In my personal experience, coming from a large “corporate” company, where women were blatantly penalized for having children by being denied promotions and pay raises due to family commitments, ENCON is a breath of fresh air. With plenty of opportunity for growth and leadership that is truly invested in the career paths of their employees (who also happen to be mothers) – ENCON blows the “glass ceiling” to pieces. I’m extremely grateful and proud to be part of a company that doesn’t make me choose between my family and being a good mother, and also developing and fostering a career path that I love.
