QA Graphics worked with Taco Comfort Solutions to upgrade a functional, templated app into one that was also well-designed and intuitive though enhanced system graphics and an improved interface.

By working with QA Graphics, Taco gained: an application that provided an improved user experience and embraced Taco’s brand standards; a highly detailed graphics symbol library that depicts Taco’s equipment; and savings in time and money.


Taco Comfort Solutions is a third-generation American manufacturer of high-efficiency heating, cooling, plumbing, and irrigation products. The company currently sells a building management tool called the LCI-3. This tool works well in its target market, but has only received small functional updates over the years, and no design improvements. The product’s functionality was fine, but the outdated look and feel was not up to par with what Taco and its customers needed.

The theme did not encompass the company’s brand and style. The LCI-3 tool also lacked the equipment graphics which had become expected by the market. Taco offered other options to provide standard graphics to their customers, but these standardized graphics did not give Taco’s building management tool the personal touch clients wanted. Taco wanted to create a custom graphics package, but didn’t have in-house graphic design resources.

Taco’s engineering department originally created the custom graphics needed for the application. However, the engineers had very little graphic design experience, and the company still felt the graphics were missing their mark. The introduction of consumer-facing products had rapidly advanced the market standards for HVAC industry graphics and interfaces.

“We knew to play at the next level we would need help,” said Danato Borelli, director of engineering at Taco Comfort Solutions.


Taco had seen QA Graphics’ work used by other industry businesses. These projects gave Taco an idea of how QA Graphics could enhance its building control application. The company wanted to utilize that expertise to enhance the app’s user experience and create a more sophisticated symbol library.

User Experience
QA Graphics’ user experience (UX) designers understand the importance of creating visually appealing interfaces that put the user’s needs first and incorporate a company’s branding. After getting a feel for Taco’s vision for the application, the designers explored the app’s functionality and brainstormed design ideas.

QA Graphics created an application map to visualize the flow of the application and made suggestions on how to improve navigation or simplify a page’s content. The UX designers also researched different ways to marry Taco’s branding with digital design trends. These efforts made the application’s design cohesive, modern, and logical. Users could easily navigate between the different application areas, including a control view with real-time monitoring, activity logs, data trending, and more.

The application was built to work at different sizes on several different devices. QA Graphics designed two separate mock-ups per page to help Taco’s developers visualize how the application would look on different screens. These page mock-ups were sized for vertical mobile devices and horizontal tablets. Once these mock-ups were approved, QA Graphics sent Taco any development specs, images, icons, color values, and font information needed to build the page within the application.

The design theme and assets that QA Graphics created will be critical as Taco attempts to expand their product family across more non-traditional offerings. The controller graphical assets will provide a template for Taco to use across other platforms and create a more consistent style between their products.

Symbol Library
Taco also worked with QA Graphics’ 3D designers and building automation system (BAS) specialists to create a custom symbol library and mechanical equipment graphics. QA Graphics’ symbol library offers static and animated graphics, including unit ventilators, underfloor units, tanks, rooftop units, and more.

QA Graphics’ specialists are experts in the BAS graphics industry and worked with Taco to build a robust symbol library. QA Graphics created all the 3D graphics and piping needed to build the system graphics within the application. The app’s library now features superior graphic representations of a user’s system, including dynamic graphics, moving fans, and pumping pumps.

Customer Experience
Taco’s team became more excited about the project as QA Graphics worked through the application upgrade and sent updates. The company was able to see how its work could be re-imagined with a modern, updated design, while leaving the desired functionality intact. QA Graphics’ designers transformed Taco’s functional but visually unappealing application into a presentation that Taco is proud to display. Taco now has a product that matches its customers’ expectations.

When asked about the process and work of QA Graphics, Borelli said, “I think that QA Graphics has a really talented team of people who can help HVAC companies move their product designs to a much more polished level. The team was friendly, easy to work with, and offered good value for the time and money spent.”


Taco gained all the graphical assets needed to prepare the application for release. The design process required very little work to be done on Taco’s part. The company’s engineers were able to refocus their limited time on product functionality, allowing for an overall faster launch for LCI-4. Taco saved time and money in resources when they hired QA Graphics’ professionals to work on their application.

Taco’s new LCI-4 application features a modern style that embraces Taco’s branding. Taco’s graphics are now custom, highly detailed, and accurate representations of clients’ systems. These graphics are controlled entirely through the app QA Graphics helped upgrade. LCI-4’s design is better what than Taco could have created without QA Graphics’ expertise, and the design process did not eat up engineering resources.

“Working with two-three experienced designers at a high level was very much worth the cost of the project. There is no way that Taco could have sourced this level of HVAC design talent locally. Sales numbers will likely increase after product launch as well,” said Borelli.
