I like these colors in this basic design I created, (dark purple, 2 tone teal and 2 ton burnt orange.
I am looking for somthing simple but eye catching, similar to the attached designs and but catered towards heating and cooling. 
Our town is surrounded by water, I like the sun/sun rays and air waves replicateing a breeze. 

Im Not personally big on characters but my wife thought of incorporating a blue crab into logo, I do not want every designer to put a crab in the logo but if a couple think they could do so keeping the logo related to heating and cooling, and simple so it dose not take away from name, I wouldn't mind seeing what you have to offer. If you choose to do a crab I think an aggressive crab with a brazing torch might look cool. Other than that I think I'd rather keep it simple like one of the attached designs.

Gilate is the man! Created exactly what I was looking for!
