I appreciate how quickly and vigiliently DGA follows up if there's an alarm including sending text messages since these days many people do not answer the phone or have their phones set to silent. That was a great idea!

The DGA Team were great to work with. There was a complicated tech issue on sight they were able to solve in one visit! Great job with Shawn the on-sight technician. He took time to describe and investigate beyond the scope of the initial request to solve the problem. Wow!! Thank you DGA!
