What are the 10 Best Furnaces?
Frigidaire iQ Drive Gas Furnace
The Frigidaire iQ Drive FG7MQ stands apart from the other furnace models of this manufacturer, with an AFUE rating of 97 percent. The unit was awarded with the Energy Star program's "Most Efficient Unit" designation in 2012." This furnace can customize operations depending on your needs–it takes stock of the indoor temperature every minute and tweaks the percentage of heating accordingly. The communicating thermostat lets you take full control of your indoor environment with customizable comfort schedules, maintenance reminders and troubleshooting diagnostics. The unit's motor is housed within an insulated cabinet, helping to make it the quietest among the manufacturer's furnaces.
Frigidaire Two-Stage Gas Furnaces
The Frigidaire two-stage gas furnaces come in two varieties–the fixed-speed and the variable-speed models.
The FG7TC-L and the FG7TA-K fixed-speed models have 95.1 percent and 80 percent AFUE ratings respectively. The two-stage heating mechanisms on these units help maintain consistent levels of heating throughout your home, while the 30-second blower delay feature was designed for a warm duct as the furnace begins operation. The SmartLite® technology adds to the durability of the igniter. An insulated blower compartment muffles operation noise.
The FG7TC-L and the FG7TA-K variable-speed models have 95.1 percent and 80 percent AFUE ratings respectively, when used with Frigidaire coils and outdoor units. The two-stage variable-speed heating mechanism on these units provides consistent heating throughout the home, good indoor air quality and little noise, according to the manufacturer. The units also feature insulated blower compartments, SmartLite® technology and a 30-second blower delay.
Frigidaire Single-Stage Gas Furnaces
The Frigidaire single-stage fixed-speed gas furnace models feature the SmartLite® technology for the igniter's extended performance life, an insulated blower compartment for quiet performance, and the 30-second blower delay feature as well. The FG7SD-M model has a 95-percent AFUE rating; the FG7SC-L has an AFUE rating of 92.1 percent; and the FG7SA-K make has an 80-percent AFUE rating. The latter make is available in downflow and upflow/horizontal versions.
Frigidaire Oil Furnaces
All types of the Frigidaire oil furnaces have an 80-plus percent AFUE rating when used in conjunction with Frigidaire coils and air conditioners or heat pumps. The units are insulated with a spun glass and aluminum foil that keeps them cool to the touch during operation. A thermosetting powdercoat finish adds to unit's exterior durability. The heat exchanger is fully welded to optimize performance.
Frigidaire oil furnaces are also available in variable-speed and downflow models.
Care and Maintenance of Frigidaire Furnaces
Frigidaire recommends that their furnaces be serviced annually by a qualified technician who must check for frayed wires, corroded electrical parts, leaks, soot and rust. Technicians should take special care in checking the venting system, and should clean the burner and heat exchanger if required. According to Frigidaire, the most effective way to increase the longevity of a furnace is to clean the filter in the unit regularly and replace it when necessary.
When your Frigidaire furnace is registered online, you can receive full warranty benefits. These include a 10-year parts warranty on all mechanical and electrical components of the furnace and a 10-year Comfort Quality Pledge on the heat exchanger. As part of the Quality Pledge, Frigidaire will replace the heat exchanger if it malfunctions within the first ten years on a registered heating unit, or five years on an unregistered unit. Those owners who register their units are also entitled to the benefits of the Limited Lifetime Heat Exchanger Warranty program.
