In 1985 Art Radichio contracted to Spectronics Corp. of Long Island and pioneered the art of Ultraviolet Leak Detection within the HVAC&R fields. A&R commercial accounts and facility associates (LILCO, Winthrop Hospital, A&P Super Store, Port Washington Flowers, and Manhasset Flowers etc.) that had refrigerant leaks were some of the first successful test prior to product availability. CNN produced an Ozone awareness video with footage from the above accounts. After field testing and in house testing Spectronics Corp. introduced a very successful Ultraviolet Leak Detection product, which made locating refrigerant leaks very easy and reduced the amount of CFCs entering the stratosphere.

What the Early Adopters are Saying About Downtobid
"We have used Downtobid for our ITBs and so far our experience has been very positive. It has saved me time on the initial page turn and I really like the number of responses we're starting to see from our subcontractors!"
"The first time our company was able to travel outside Atlanta! Bidding in a new market and wasn't getting any hits on Drywall. Requested a boost and with 5 days I had 2 committed bidders and 1 submission. Using them on my next project."
""I love, the personalization of it. You get it more directed towards the contractors that we need. You, make it a little more personal than putting it on Blue Book or Planhub or anything like that. You let us communicate with the subcontractors, so we can narrow it down from what you've already narrowed it down from. We get more, more specific, more detailed quotes, more the correct quotes that we're looking for from you guys as opposed to maybe other places.""
