What are the 10 Best Furnaces?
yne is a comfort systems manufacturer that sells products through the brand names Broan, Maytag, Tappan, NuTone, Frigidaire and Westinghouse. Nordyne is behind various technologies such as the iQ drive, which works to constantly adjust firing rates for the utmost efficiency. Other features of the Nordyne line include ecoLogic products with environmentally friendly and corrosion-resistant features. The company also uses “demand flow technology,” a quality assurance system that involves many checks throughout the manufacturing process for better product reliability.
Nordyne iQ Gas Furnaces
Nordyne produces quiet, high-efficiency furnaces able to reach up to 97 percent AFUE. The manufacturer notes that this efficiency can be enhanced with its iSEER technology. Insulated cabinets and a gradual start feature minimize sound production. Finally, Nordyne’s iQ models have a “drive controller” thermostat for easy adjustments and to provide maintenance reminders and diagnostic information.
High-Efficiency Gas Furnaces
Nordyne manufactures several varieties of high-efficiency gas furnaces. With AFUE ratings of 92 to 95 percent, these units are available as both single- and two-stage fixed speed units as well as two-stage variable speed units. Blower compartments are insulated and homeowners may opt to pair the furnace with iQ Drive air conditioners or heat pumps for additional savings.
Standard-Efficiency Gas and Oil Furnaces
Nordyne’s standard-efficiency furnaces also are available in many stage and speed variations. Nordyne produces both gas and oil furnaces with 80-percent AFUE ratings. The oil furnaces options include low boy models as well as models with downflow configurations. Some units in this efficiency range come with a blower delay that warms the duct at start-up and a post purge that improves the heat exchanger’s durability.
Nordyne’s packaged units range from 13 to 20 SEER and offer an AFUE rating between 80 and 81 percent. An iHybrid model is available that has two fuel sources and an ecoLogic green seal. Nordyne manufactures gas and gas/electric operating packaged units with such features as a 1.5-mm-thick corrosion-resistant finish and easy control access. Two- and four-stage heating is available with variable- or fixed-speed motors.
Although each brand name offers specific warranties on its own products, these furnaces generally feature a 10-year parts warranty. Heat exchanger guarantees range from 1 to 10 years. Product registration is encouraged for full warranty benefits.
