Why You Should Choose Us for Air Conditioning Services
Russell & Abbott isn’t here to just work on your AC fast and then vanish, possibly leaving you with subpar work. We are an employee-owned company, and our owners are involved in day-to-day operations. It’s our goal to ensure our customers receive the best air conditioning service—and that means not only quality work to install, repair, and maintain equipment, but professional service from people who care about your comfort and about your home.
ONYX Heating and Cooling Systems
We know you want a durable air conditioning system for your home—and this why you’ll want our special ONYX line of systems. These are available exclusively through Russell & Abbott and are designed with the climate of East Tennessee in mind. You can have a ONYX heat pump system installed for heating and cooling around the year, and we also install gas/electric split systems combining a great air conditioner with a natural gas furnace.
Our Exclusive 10-10-10 Warranty
We offer an exclusive 10-10-10 Warranty for our ONYX heating and cooling systems. You receive a 10-year warranty on all parts (no exceptions), a 10-year warranty on labor, and a 10-year warranty on maintenance. If you sell your home, the warranty is transferable to the new owner if they purchase maintenance. And you own the maintenance on the warranty, so if you move to a new house in our service area, you can keep the unused portion of maintenance for a new system. Schedule an appointment with our air conditioning experts today.


We know maintaining a home can be expensive. That’s why we offer promotional financing options with no pre-payment penalty you can choose from that will best suit your needs.
