2009Founded in McDonough
Built on service
Three generations taught us what “the best” really means.
Being called Absolute Best Air sets the bar. We have to earn that name by knowing the system, respecting the customer and getting better on every call.
Founder David Longino began riding along on HVAC calls with his father at age nine. His grandfather owned A to Z Refrigeration & Air Conditioning. His father owned a geothermal engineering company. David carried that family knowledge into public service as a firefighter, then founded Absolute Best Air to give customers clearer answers and build meaningful careers for great people.
