Desirable features in a cheap gas furnace include a high efficiency rating and an Energy Star label, digital thermostat hookup, variable heat output and speed, an optional upgrade to the air filtration system, and a lengthy warranty. A furnace with 80% efficiency is a good option for frugal homeowners, especially those who live in mild climates. The Energy Star label is awarded to furnaces with 85% efficiency or higher -- very few of which fall into the budget price range. All the furnaces on our list hook up to digital thermostats for precise and efficient temperature control. Variable speeds and heat output allow a cheap furnace to heat more evenly and be more efficient. An upgraded air filtration system can benefit someone with allergies or breathing problems. And, of course, the longer the warranty, the better.
