Our history
1981
2024

Simpson Sheet Metal Heating and Air Conditioning has been a family-owned operation since 1981 when Bill and Nancy Simpson pooled their skills to form the company.  Bill had years of HVAC experience, and Nancy, after 15 years in banking, brought business acumen to the venture. They began with six employees working mostly on heating and air conditioning systems for homes and quickly grew into commercial projects and sheet metal fabrication.

After Bill’s unexpected death in 2009, Nancy and the rest of the Simpson team stayed the course, never losing sight of Bill’s vision and values for superior customer service and high-quality workmanship.

Today, with 100 employees and loyal customers throughout the Greater Bay Area, Lake and Mendocino counties, Simpson is still family-owned and operated and maintains close ties in the Santa Rosa community.

Daughter Barbie Simpson, who has worked at Simpson since she was 16, is now owner and president. Bill and Nancy’s grandchildren also work for the business; Frank oversees Business Development, and Nancy is the Vice President and Office Manager.

Simpson has established itself as a leader in providing top-quality service, sheet metal fabrication, repair and maintenance, and its commitment to family, friendship and hard work promise to endure for generations to come.

When Bill was asked what he attributed to the success of his company, he would always say this. He believed it with his whole heart and his sentiments have been passed down from generation to generation in the family business.
