Information on the best gas furnaces is obtained by reading the latest online reviews of leading appliances. Examples of platforms that carry such reviews include WebHVAC.com and TopTenReviews.com as of 2015.
Read reviews on leading furnace brand names such as Maytag, Carrier, Lennox, Trane, Armstrong, Bryant Evolution, York Affinity, Amana, Goodman, General Electric, LG and Whirlpool.
These reviews provide valuable information about the top rated gas furnaces in terms of efficiency, modulating and guarantee duration. The first three gas furnaces on TopTenReviews.com are Trane XC95m, Lenox Signature Collection and Maytag PGC3MQ.
These are followed closely by Carrier Infinity 98, Bryant Evolution System and Armstrong. The last four gas furnace brand names on the same website are SL280V, Amana AMVM97, York Affinity YP9C, and Goodman GMVM97 Modulating Gas Furnace. Most of these furnaces score at least 97 percent Annualized Fuel Utilization Efficiency or AFUE, and have 10-year warranties.
Reading extensive online reviews equips the consumer with information on what to look out for in a furnace. While a furnace with multiple features is likely more reliable, it is also likely to be more expensive than a furnace with simple functionality. Propane and natural gas furnaces are perhaps the best appliances to keep the cold away during winter. Not only are they cheap to maintain, produce safe and efficient heat.
