Furnace Ratings part 16, Reviews of the SmartAir, Tappan, and Tempstar brands



This brand is available for either purchase or rental in Canada and is from RELIANCE HOME COMFORT. They do not actually manufacture any equipment but take Rheem, Goodman, and Payne furnaces and re-brand them with their own private label. They provide installation, service and maintenance but the guarantees on the heat exchangers of the units is not as good as the other brands. 


This brand is made by NORDYNE which is a part of NORTECK GLOBAL HVAC. The FG7SC/FG7SL models are basic furnaces with a 92% efficiency and use "SMARTLITE" control to extend the life of the hot surface igniter. They are compact units for easier installation and are backed by a good warranty. 

The FG7TC/FG7TL units are premium models with an efficiency of up to 95% and they have a good warranty. The iQ DRIVE models are ultimate units with a 97% efficiency and the ability to communicate with the other parts of the home's heating and cooling systems to maximize efficiency. The brand is only available through their contractor network in the USA.


This brand is from INTERNATIONAL COMFORT PRODUCTS which is a part of UNITED TECHNOLOGIES CORP. The PERFORMANCE 92 and 95 units are a basic builder grade high efficiency furnace with a guarantee that is not very good. The SMARTCOMFORT 96 is a better choice in the basic category as it has an ECM blower motor for reliable and energy saving operation as well as a better overall warranty. 

The SMARTCOMFORT DELUXE 96 is a good premium furnace with the ability to communicate with the other parts of the home's HVAC systems but the warranty is only average. The SMARTCOMFORT 98 (F9MAE) is an ultimate furnace that is backed by a decent guarantee. It has a variable speed inducer motor for quiet and efficient operation but the brand is only available through authorized dealers in the USA and Canada.
