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.
