Frederick R. Barnard, an advertising executive, coined the phrase, “A picture is worth a thousand words.” And how right he was. If Barnard knew, back in 1921, the power of this statement, and, today, with the ease of one’s cellphone, he would probably revise his phrase and offer, “A picture or video is priceless in communication.”
Today, cellphones go beyond simply capturing an HVAC system’s existing conditions and illustrating field reports. Cellphones have the capabilities to video an HVAC “walk-around,” reinforcing the 21st century YouTube blog phrase, “If a picture is worth a thousand words, then a video is worth a million.”
