Robbins Heating & AirLogo Design Contest

Quality People, Quality Performance

Our brand is very recognizable in the community. We don't want to move away to far from what we have. Due to recent competition arising who look very similar to us, we are looking to keep a similar feel and look but refresh, update, and add some new colors. Emphasis on adding new colors. Our competition looks and dresses very similar to us. We don't want to loose business to them just by people assuming we are them.
Our audience is homeowners and business owners.

Our current colors are royal blue and navy with some white and black.
We would like to keep some blue element to keep the feeling similar to our customers but mix in other colors.
Other colors we would like to mix in are greens, oranges, and greys.

Here is our existing logo. How can we keep the feel and familiarity and spruce it up??
