Gas furnace prices vary widely because of several factors that are discussed below. Relatively small gas furnaces with basic features can be found for less than $1,000. Large furnaces with high-performance bells and whistles can cost more than $4,500.
Factors Affecting 2014 Gas Furnace Prices
Here are the three keys to gas furnace costs.
Efficiency: The least efficient furnaces on the market are 80% AFUE (annualized fuel utilization efficiency) and the most efficient models now boast better than 98% efficiency. Obviously, the more efficient the model is, the more it will cost.
If winters are brutal where you live, then it would probably be cost-effective to choose a super-efficient furnace. In warm climates, it would likely take 7+ years of lower heating bills to make back the extra you would spend on a very efficient model.
Performance: There are three levels of performance, and furnaces get more expensive as the performance goes up. Basic furnaces have single-stage gas valves, so they heat at full capacity whenever they’re running. This results in wasted fuel and some temperature imbalance. Single-stage furnaces are the cheapest on the market.
Two-stage furnaces run at low capacity when maintaining temperatures and at high capacity when a temperature boost is needed. These furnaces may also have a variable-speed blower that helps create a more comfortable climate in all seasons. Two-stage furnaces are moderately priced.
Modulating gas furnaces have a variable-capacity gas valve, so they deliver precise amounts of heat to keep temperatures evenly balanced. They have variable-speed blowers too for maximum indoor comfort. These are the most expensive models on the market.
Note: Here are the efficiency ranges of each type of furnace.
Size: The greater the furnace’s capacity, the more it will cost. The range is about 45,000 BTU to 140,000 BTU.
Gas Furnace Prices
As you can see, there’s a lot of variables. A small, single-stage furnace will cost a fraction of what a large modulating furnace costs. Here are some examples. Keep in mind that each category includes furnaces from small to large and with differences in performance.
