The air handler was tripping a three amp breaker. They showed up when they said they would, quickly found the problem and took care of it effectively.

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!
