Here you go 2 scketches based on your brief where you can ask for any changes or make any suggestions. I think that they have strong colors and modern layout, and they feature all the company activities in a simple way, by the house silhouete with the leaf dividing the cool and heat, and the dots for the plumbing points... I think that the redish color applies better to the word "thermo" but posting blue option like you seem to prefer too. If any sounds promising, even after contest ends submissions are possible for the 1st ranked designer.
Kind regards,
Claudia
