Absolutely awesome experience having a mini split system installed. Garrett came out and assessed our house and answered all questions about the process. Big shout out to Todd and Derrick who did the majority of the mini split work, they were rock stars. Courteous, kind, full of knowledge, and clean! Highly recommend Green Collar for any insulation/ mini split work. Thanks guys!

My thanks to the crew from Green Collar for their work on my house June 2025. Nick, Tyler, Clint, Brandon and others worked hard insulating and helping make my home more energy efficient. They provided thoughtful evaluation of what was needed, and excellent communication about adjustments to the work plan. Good clean up and really nice folk to have working here. Cheers
