Den-Son Inc. Cooling & Heating, Your HVAC Contractor Since 1972

Den-Son Inc. Cooling & Heating was founded in 1972 by Dennis Boren to support his family. As a young entrepreneur, he had his doubts. However, he persevered and his heating and cooling business flourished.

Rick and Tammy Boren

Rick Boren started helping his dad with the business at the age of 13 during the summer. After Rick graduated Southwestern High School in 1981, he became a full-time technician. He performed routine maintenance and learned about sheet metal fabrication, in addition to learning how to install furnaces and air conditioners.

Ten years later, he was incorporated into the business and the company’s name was changed to Den-Son, Inc. Rick’s wife, Tammy Boren, joined the team as the administrative assistant in 1994. She later became the office manager.

In 2001, Dennis passed the reigns down to his son, Rick. Nathaniel, Rick and Tammy’s son, joined the business at the age of 16 as a part-time worker six years later, just like his dad did in 1976. Nathaniel joined the team full-time as part of the install team in 2007 and later became the Install Manager.

We continue to grow as a company. We still offer maintenance, installation, and cooling and heating services for all makes, models and brands. We also provide a full range of services for air-source and geothermal (ground-source) heat pumps, whole-house generators, and tank and tankless water heaters. You can trust Den-Son for quality and friendly service.
