2nd. entry. I designed this logo with the environment in mind. Hence the tagline at the bottom, " Keeping your environment comfortable, and green". I know that the systems that contractors install nowadays are highly Efficient & Green. I also included a badge in the center of the duct and I added the creases for detail. I will send a version without the center badge also. I have many friends that are tinners. it's a great trade. I hope you like the logo that I created for you, and your feedback is always welcomed. This logo can be revised to your liking. Let me know.
All the Best,
Jim
