About Us

Over a decade ago, Jefferies Inc. first opened its doors in 2007. The business was inspired by a hope to pave the way on how an HVAC company should be operated. Our passion for our work starts from the top with our founder, Russ Jefferies. We take the utmost pride in every job we do and are dedicated to serving our customers and community with the highest level of support.

Building Relationships is More than Customer Service

Building personal relationships with our customers have built the business foundation we currently have today. We started with one customer over 10 years ago, meeting over a cup of coffee and a conversation. We continue the tradition of individualized interactions, face to face conversations and a handshake today. Our loyal customers have contributed to the growth of this company by referring their friends, families, neighbors, business partners, and other business owners. They trust us to the fullest extent, knowing their referrals will be taken care of with honesty and integrity. We are appreciative of the referrals and are thankful for the opportunity to serve each and every one of our customers.

Our Mission

At Jefferies Inc., we pay close attention to detail and are committed to resolving any problems efficiently, while making the right decisions for our customers and our business. We strive to make a difference while providing long-term solutions to our customer’s needs. We keep an understanding of our purpose to put others first at the forefront of all we do.
