How to Tell a High-Efficiency Gas Furnace from a Mid-Efficiency Furnace

It’s super simple to determine with just a glance the difference between a high-efficiency gas furnace and standard-efficiency furnace. Just look at the exhaust. If it’s a single steel exhaust pipe it is a standard or mid-efficiency. If it has a pvc exhaust it is the higher efficiency version. 

The higher efficient furnaces are able to extract additional heat form the combustion process and as a result their exhaust is cooler and can be vented through pvc. If you have an older furnace that is rated at 80% efficiency one way to look at is 80% of the fuel you burn heats the house and 20% goes out the exhaust. Logically, a furnace rated at 95% is going to save you fuel costs. These furnaces do cost more initially but they make up for it over time.
