I obtained my license because I couldn't find a company I trusted to care for my system.  Not long after, my neighbors got wind of it and asked me to take care of their systems.

Tammy, Co-Owner

Mitch worked as an electrician at Miller Brewing while unintentionally building a customer base.  Within a year of obtaining his license, we were forced to make a decision.
