Y’all got a clue. First BDP I’ve run across. Made by BDP Company of Indianapolis, IN.
It’s a heat pump.
Picture has Model, Serial & Product #'s.
What you think of them cruddy fan blades. Here’s what I tell em when I see the crud covered blades on the fan.
The filter was not properly in place to filter the air and the blower fan blades are covered with crud which impedes the operating efficiency of the unit. This has also usually allowed dust to come in contact with the wet air conditioning coils. Wet plus dust equals mud on the coils equals the coils being partially blocked (I can’t see the coils to verify this though). Blocked coils further degrade the operating efficiency of the unit. For energy efficiency & lower operating costs, I recommend that you have the heating and cooling unit serviced and cleaned (to include removal and cleaning of both the fan and the coils) by a heating and air conditioning contractor capable of fixing any other problems found while the unit is dismantled.
(Digital cameras are great for reaching in to get pictures of fan blades).
