Gas Furnace

Gas furnaces last, on average, about 20 years. Which means you need to think long-term about the efficiency and comfort features your new furnace will include. Here are some things to know before purchasing a new gas furnace:

Install is #1. Even the best made gas furnace will not perform without a quality installation. Make sure you hire a licensed contractor who is going to address your ductwork and other home needs in addition to new equipment. A proper installation should cost more upfront, but will save you in service costs and headaches down the road.

Buy the highest AFUE you can afford. Annual Fuel Utilization Efficiency (AFUE) measures the efficiency of your furnace. The higher the AFUE, the more efficient your gas or oil furnace is. An 80% AFUE furnace converts 80% of the fuel into heat; the other 20% is lost up the chimney. Most furnaces installed in the past 15 years are around 65% - 70% AFUE. Today's minimum standard is 78% AFUE, but many rebate and tax credit incentives are tied to heating efficiencies above 95% AFUE. It's important to ask your local NuTone dealer about the standards in your region, and what state, federal, and local utility incentives are available.

Invest in comfort. Today's furnaces can provide more home comfort than those from a decade ago. Many high-efficiency furnaces contain features that will make your home more enjoyable. Look for two-stage and variable-speed models that run at different output (capacity) levels to reduce noise and provide a better mix of air throughout the home (reducing hot or cold spots). Some extremely efficient furnaces, like the 97% AFUE NuTone iQ Drive® modulating gas furnace, can vary the output level to provide the quietest and most comfortable indoor temperatures.

Run the auto fan. Your new furnace's thermostat may have a "fan on" setting. If so, consider running the fan year-round. It's a great way to even out temperatures on multiple levels and reduce hot and cold spots as it continues to move air even when the furnace or air conditioner isn't running. For even better temperature control, ask your NuTone dealer about zoning.
