Who We Are

Air Assurance began in 1985 with Mike and Narissa Rampey, and was later joined in ownership by their son David in 2003. Today, they are proud to maintain the largest full service HVAC and Plumbing fleet in the Tulsa metropolitan area.

Air Assurance specializes in residential and commercial comfort solutions including heating, air conditioning, indoor air quality,  geothermal service and installation, and plumbing services. Air Assurance’s philosophy is to provide the best possible service to its customers. Exceptional service and customer "wow" factor have been instrumental in their growth, and they will do everything possible to create positive experiences.

Although they sell the best heating, air-conditioning, and plumbing equipment available today, their greatest asset is their employees. They continually seek out the very best talent in the industry, people who understand the importance of customer relationships and what it means to offer exceptional customer service with true integrity.

Over the years, Air Assurance has received many awards including the ACCA National Contractor of the Year, Best of Tulsa, Best of Broken Arrow, and Best in Oklahoma along with Tulsa's Fastest 40 growing companies in 2011-2012.  They have been recognized by Lennox as one of their top 1% of dealers in North America. Air Assurance was the first contractor in the nation to provide their customers with an all-NATE certified (highest qualifying certification) technician staff. This means, when they send a technician to your home, you can count on safe, effective, and efficient service and installations of today's most sophisticated heating, air conditioning, and plumbing equipment.

Starting at age 7, David spent his summers running service with his dad, learning the value of treating customers with respect, honesty, and integrity. In 1985, David's family started Air Assurance, building their reputation for doing just that. Many summers, spring and fall breaks, and any other time throughout high school and college were spent installing, servicing, and ultimately, designing comfort systems. After graduating Harding University, David went into the coorporate world working for Hormel Foods as an account manager covering over half the United States until the opportunity to buy the family business became available. Since then, David has continued the Air Assurance tradition of putting the customer first, while providing superior comfort solutions for residential and commercial customers alike. If you know anything about the Rampeys, you know their name and their reputation means absolutely everything. This holds true in everything they do within their business by putting their name behind their work and giving their business that personal touch so many companies lack. David loves to give back to the community through serving in several different capacities. He has served as President of the Broken Arrow Rotary Club, on the executive board of the Broken Arrow Chamber of Commerce, Leadership Broken Arrow, and Junior Achievement
