With an AFUE rating ranging from 80% to 95%, the Ruud Achiever Series has the largest selection and varieties of gas furnaces. Consumers can choose from single or multi-stage models in upflow, downflow, and horizontal capacities. Certain models contain the Super Quiet function which features a door and top-plate barrier between the furnace’s operation and the outside environment to reduce noise level.
Another special feature of the Achiever Series is Ruud’s exclusive Dual Comfort Control. This system keeps temperatures throughout the home consistent and automatically adjusts efficiency levels according to the conditions outside to lower cost and lower energy usage.

Consumers have the option of choosing between a value line 4-speed PSC Motor and a high efficiency ECM motor to control the airflow throughout the home.
Care and Maintenance
Ruud recommends frequent cleaning and replacement of furnace filters for optimal function and efficiency. Filers may need replacing as frequently as once a month during stages of daily use. Homeowners should also vacuum the unit regularly to avoid dust accumulation within the furnace. For additional repairs and scheduled maintenance, consumers should contact a local Ruud representative.
While all furnace units carry a 10 year conditional parts warranty, heater exchanger and unit replacement warranties vary upon unit. Many models carry a limited lifetime warranty for heat exchangers and an additional 10 year conditional unit replacement. A 5 year limited parts warranty is also available for specific models. As with all Ruud heating and cooling products, consumers can purchase additional protection through the Protection Plus program.
