From Humble Beginnings to HVAC Excellence

In the sweltering heat of a Naperville summer, the story of Four Suns Heating & Cooling began. Founded by the Thompson siblings—Mark, Sarah, Emily, and John—this family-owned business started with nothing more than a single truck and a shared dream of bringing comfort to their community.

The early days were challenging. Long hours were spent driving between Plainfield, Warrenville, and Wheaton, offering air conditioning installation and repair services. Often, they’d return home exhausted, covered in dust and sweat, but their determination never wavered.

Overcoming Obstacles

As with any new business, Four Suns faced its share of setbacks. During their first year, a particularly harsh winter struck Illinois, causing a surge in heating system failures. The team worked tirelessly, sometimes pulling 20-hour shifts to ensure no family was left in the cold.

This dedication didn’t go unnoticed. Word spread about the small company that went above and beyond, and soon, Four Suns’ phone was ringing off the hook with requests for HVAC installation and AC service.

Growing with the Community

As their reputation grew, so did their team. Four Suns began hiring local technicians, training them to uphold their high standards of service. They invested in state-of-the-art equipment and continually educated themselves on the latest HVAC technologies.

Their commitment to excellence paid off. Within five years, Four Suns Heating & Cooling had become a household name in Naperville and the surrounding areas. They were no longer just a service provider; they were a vital part of the community.

The Four Suns Difference

What set Four Suns apart wasn’t just their technical expertise, but their unwavering commitment to customer satisfaction. They treated every home as if it were their own, every client as family. This philosophy became the cornerstone of their business model.
