The average gas furnace will keep you warm for about 20 years. So think long-term about efficiency and features that you want your new heater to include. Here are some tips before purchasing a new gas furnace:

Installation is critical. No matter how well your new furnace is made, it won’t perform well 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 high-quality installation will cost more upfront, but will save you in service costs and headaches down the road.

Consider a high AFUE. 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 Maytag® dealer about the standards in your region, and what state, federal, and local utility incentives are available.

Consider 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 Maytag® 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 Maytag® dealer about zoning.
