In October 2016, operations at the new facility ramped up and the first Goodman air conditioner and gas furnace units came off the line. [12] In 2017, the construction of the huge facility concluded to consolidate Goodman’s HVAC manufacturing, engineering, logistics, and customer support under one, very large 4.1 million square foot roof.

4.1 Single-flashing: Fl A flash is repeated regularly at a rate below 50 per minute. Fl G 5s 4.2 Long-flashing: L.Fl A light flash, duration of more than 2 seconds (long flash) is repeated regularly. L.Fl W 10s 4.3 Group-flashing: Fl(x) A group of a specific number of flashes are repeated regularly. Fl(3) R 15s 4.4 Composite group-flashing: Fl(x+y)
Another important innovation from Chance Brothers was the introduction of rotating optics, allowing adjacent lighthouses to be distinguished from each other by the number of times per revolution that the light flashes. John Hopkinson, the noted English physicist and engineer, invented this system, while employed at Chance Brothers.

Either a quick or a very quick sequence of light flashes may be used; the choice allows for two similar nearby marks to be uniquely identified by their lights. A cardinal mark may be used to accomplish the following: Indicate that the deepest water is an area on the named side of the mark; Indicate the safe side on which to pass a danger
The annual fuel utilization efficiency (AFUE; pronounced 'A'-'Few' or 'A'-'F'-'U'-'E') is a thermal efficiency measure of space-heating furnaces and boilers.The AFUE differs from the true 'thermal efficiency' in that it is not a steady-state, peak measure of conversion efficiency, but instead attempts to represent the actual, season-long, average efficiency of that piece of equipment ...
