Hear What Our Clients Have to Say
"We recently had Todd Derrick and Brent install some mini splits. They were very respectful, timely, and professional. They cleaned up as they went and even made sure to clean up any dirt tracked in from their shoes. They made sure to ask if we had any questions along the way and showed us how to use the mini splits before leaving. We are very happy with the work that was done and highly recommend Green Collar!"

"Jeff, Nick, Wallace, Erin and Tyler took care of weatherizing my home today. They replaced insulation, did part of my basement, did some testing and more, they were THE nicest crew I have seen in a very long time. They were so polite and thoroughly described what they were doing. It’s rare to see an entire crew be that kind and awesome. But I honestly can’t say enough!!!"
