You've found the team to trust when it comes to comfort in Knoxville and the surrounding area. Russell & Abbott is an employee-owned company offering the finest HVAC services for homes and businesses. We’re community-oriented and take pride in providing service that’s not only top-level and professional, but also courteous and friendly. Our technicians are thoroughly trained and experienced to handle any HVAC need. Also, we carry a CMC-C License from the State of Tennessee, something most companies do not.

Our ONYX Line of Heating and Cooling Systems

When you invest in HVAC equipment, you want to know your money is going to a system that will do the job and last for many years. One of the best investments you can make in comfort is a durable ONYX system. This is a line of heating and cooling systems manufactured with the East Tennessee climate in mind, and Russell & Abbott offers them exclusively.

All ONYX systems come with our special “10-10-10” warranty. You get a 10-year warranty on parts (no exceptions), a 10-year warranty on labor, and a 10-year warranty on maintenance. The warranty is transferable if you sell your house, and if you move to a new home in our service area, you can keep the unused portion of maintenance for a new system.

Russell & Abbott serves Maryville, Knoxville, Alcoa, Blount County, Knox County and Loudon County.
