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.

We install the best air conditioners and provide thorough repairs and maintenance. Our Comfort Club will see that you have a reliable and effective system!

  • Heating: Our certified Knoxville HVAC pros work with gas furnaces, electric furnaces, heat pumps, and more. They'll make sure your winter-weather needs are fully met. We emphasize safety and take extra steps to ensure gas-heating systems are operating at the safest levels. We've earned the trust of homeowners over the years, and we'll earn your trust as well.
