Reviews
All the technicians are too notch. Never have a complaint.
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!
Great company to work with. We have them service our GeoThermal unit twice a year and they are always on schedule, always on time and always efficient.
Great service and friendly, trustworthy staff. Highly recommend them.
Been 3 years since the expert installation and flawless service.
