HVAC Company Logo & Brand Identity

I'm looking for a professional and traditional logo design for my HVAC company, Yemtech, along with a comprehensive brand style guide, business card, and letterhead.

The project requires:

- A logo that embodies a professional and traditional style: The HVAC industry is often associated with reliability and durability, so a design that reflects these attributes would be ideal.
- A complete brand style guide: This should include all technical data for the logo creation, such as font names, color specifications, shapes, and more. The guide should provide clear instructions for consistent brand representation across all platforms.
- Design of a business card and letterhead: These should align with the overall brand identity and reflect the same professional and traditional style.

While I don't have a specific color palette in mind, the designs should appeal to my primary target customers, which are predominantly residential homeowners. Therefore, the color scheme should be accessible and appealing for this demographic.

Ideal skills for this project include graphic design, brand development, and familiarity with the HVAC industry could be an advantage. Please ensure your portfolio includes examples of professional and traditional designs.
