Would like a heat and cool logo in design

C'est ce que Cofield & Co Plumbing & Aircon recherchait dans leur logo design

design for new business logo want simple but modern
Liking some of the designs for the people who have laid the design down needs to be in your face more as will be using on work vehicles/invoices/business cards etc
Example to follow something like below but with out the roof on first and the other maybe bolder colour as detailed below
Thanks
