ONYX™ Heating and Cooling Systems
When you invest in a new heating and air conditioning system, you want to know that you are spending your money wisely. You not only want a great HVAC system, but you want one will stand up to the toughest of demands. That is why you want an ONYX. This line of systems draws its name from onyx, one of the toughest crystal formations to be found in the natural world. Not only are these systems durable and dependable, but they are manufactured with the conditions of East Tennessee specifically in mind.
Of course, even the best heating and cooling equipment is going to fail to live up to its full potential if you fail to schedule its installation, maintenance, and repair services with qualified professionals. You don’t have to worry about that when you choose an ONYX system, though. These exceptional products are available exclusively from Russell & Abbott. You can count on great manufacturing paired with outstanding service quality.

Heat Pumps
Our ONYX heat pumps are available as both split systems and packaged systems. A split system heat pump is an excellent choice for both heating and cooling a home in our climate. They are excellent replacements for standard split system air conditioners and furnaces because they can operate as both heating and cooling systems. Packaged heat pumps operate the same, but all the components are housed in a single outdoor unit, an effective option for saving space.
Dual Fuel Systems
You may wish to stick with the combination of an air conditioning system and a gas furnace. If so, then the ONYX gas/electric split system is one of your best choices. We offer dual fuel systems in single or two-stage furnaces and single, two-stage, or variable speed multi-stage air conditioners. We also offer packaged units for our dual fuel system installations. As with all of our ONYX equipment, these dual fuel systems come with our special 10-10-10 Warranty.
10-10-10 Warranty
We have the confidence in our ONYX heating and cooling equipment to back it up with one of the strongest guarantees you’ll find. It’s our "10-10-10 Warranty" which comes with the purchase of a new qualifying system. This means you get:
- 10 Years All Parts—No exceptions!
- 10 Years Labor
- 10 Years Maintenance
What this all comes down to, and what it means to you, is that if your unit fails and it’s registered, it’s covered—no exceptions! We stand behind our equipment at Russell & Abbott and know you’ll receive fantastic service from your durable ONYX installation in Knoxville, TN and the surrounding areas.
