They are incredibly professional and know what they are doing. Prompt, friendly; always gentle reminders to change filters, but always bring filters with them knowing you won't member. Would not buy equipment or have it serviced from any other business.

Tim is my Gartner service person & I would not have anyother person into my house. Tim is wonderful

and he has a terrific personality. Also, he i very intelligent. I hope that this review will be entered into

his record so that when it's Money Raise Time this review will be considered.

Technician arrived on time. He phoned about 20 minutes before his arrival as requested. Very efficient and helpful, as is always our experience with Gartner.
