giving more prominence to "heat and air, inc."... also a slight modification in the center of the design to build on the hvac concept... i increased the size a bit for you to see the detail. good luck down the home stretch!
noticing your most recent comment, i will say there may be some instances with #49 where the watermark may need to be omitted. the focus of this design is on the name and the 'O' mark. however, in most applications, the watermark flag should suit.
