How much does it cost to replace a Furnace?


The size of your home is a major factor when determining the price of a new furnace. Furnaces come in various sizes, each designed to heat an area up to certain square footage. The AFUE (Annual Fuel Utilization Efficiency) rating also affects the price and can range from 80% to 97%, with higher numbers indicating greater efficiency and lower energy costs. An 80% efficient furnace will cost less but be much less efficient than its higher-end counterparts, resulting in 20% of your energy costs going straight up the chimney. On the other hand, 96%-97% efficient furnaces are more expensive but they are able to retain more energy and thus require only 3-4% waste escaping out of your home’s chimney. One-stage furnaces will be either on or off and provide no option to reduce energy consumption. However, upgrading to a two-stage or variable speed furnace can help you save on both gas and electric bills as it runs at a lower RPM. Additionally, high-efficient systems often offer utility rebates which makes the switch easier financially. Lastly, many companies provide financing options such as seasonal rebates, discounts, and same-as-cash financing.
