Digital cameras seem to be everywhere, and for many good reasons. Put into the hands of a foreman on the job or an estimator viewing a project before preparing a bid, a digital camera used in conjunction with e-mail can save an HVAC contractor time and money and increase productivity throughout the business day, from bidding to final billing.
An estimator who snaps digital images while walking a job doesn't have to rely on memory to reconstruct the field conditions and, on second look on a computer screen, might discover a condition not noted on first view. As preparation of the estimate, the easy referral to digital images could save a return visit or facilitate a quick clarification of an observed condition.
