Price: How much does it cost to replace a furnace?

Cost to Replace a Furnace - Denver, CO

The only way we can give you an accurate price is through a free in-home estimate. However, we can say that the price varies based on these factors:

  • Furnace size—Furnace size is measured in BTUs. Smaller furnaces are cheaper; larger, more expensive. To find the right furnace size for your home, your HVAC Design Consultant will perform a detailed calculation that includes analyzing your home's energy efficiency, ductwork sizing, and square footage.
  • Furnace efficiency level—Furnace efficiency is measured in AFUE. A higher AFUE rating means the furnace is more efficient, but it also means it's more expensive. Also, high-efficiency gas furnaces (90% to 98% AFUE) require extra venting, which increases the installation cost.
  • Fuel type (Gas vs. electric)—Electric furnaces typically cost less to buy and, in some instances, to install than gas furnaces. But a gas furnace typically costs less to run. Your comfort specialist will help you find the best fuel type for your home.
  • Length of manufacturer warranty—A longer warranty costs more but gives you peace of mind. If there’s a problem with the product, you won’t have to pay out of pocket for the parts to fix it.
  • Pulling permits—We are required to pull permits, which is an additional fee that varies depending on the municipality you live in.
  • Ductwork modifications—We may need to modify the ductwork if your new furnace is significantly smaller or larger than your existing unit.
  • Accessibility—If your system is located in a crawl space, attic or tight closet, this will increase labor costs because it's more difficult to install.
