Trane’s Best Furnaces
Find out which furnace ranks #1 in these key categories: most efficient, quietest, and best value.
Furnace features you need to know
- Energy Efficiency - Furnaces, like air conditioners and any other home appliance, consume energy to work. Some furnaces use less energy than others to get the same results. A furnace AFUE rating can help you tell the difference. Annual Fuel Utilization Efficiency (AFUE) is a measure of a gas furnace’s efficiency in converting fuel to energy. A higher AFUE means greater energy efficiency. Greater energy efficiency can translate into lower monthly energy costs. Keep in mind: Standard efficiency = 80% AFUE. High efficiency = 90% AFUE and above.
- Sound Level - For residential areas with strict noise level standards or if space is limited, having a quiet running furnace can be key. In furnaces, moving parts like blower motors, fans as well as cabinet insulation quality can limit noise. Many units are rated with a Nominal Sound Level — the average sound level in decibels. The higher the number, the louder the unit. For example:
- Value - We don’t define best value as our lowest priced unit. At Trane, we define value by identifying the furnace that delivers a high-efficiency rating and updated features but is more affordable than our most advanced units. Think of these like Goldilocks — not too high, not too low — just right.
