Greg Holzinger, This year

I've been a Collier's customer for over 16 years, ever since they installed our geothermal system.
Every representative has always been punctual, courteous and thorough.
An absolute joy to work with!

Scheduled maintenance performed. Arrived on time and performed system checks and basic cleaning. Answered all of my questions and took care of minor issues.
