My first impression is that your page is crowded (using a 1280x800 screen res).
The colors you're using are reminding me of google ads. That's not a positive point. Red + blue + green + yellow is not really a good choice either.
I would stick to the green and red in your logo and get rid of the blue. Yellow is ok to emphazise a specific content box.
The little blue box with a house and the one with a flamme would be great either in red (color of heat, and the one in your logo), or in green (color of environment-friendly energy (sorry if there's a specific word for that, English is not my mother language).
Really, drop the blue background on the search bar, drop the blue color overall. It will give a neater feeling to your layout, will also help "uncrowd" the website. With so many colors, the user doesn't know how to look, especially with 3 primary colors together.
Remember, that's my opinion, and of course, tastes are different in each individual
