When Should You Replace Your Furnace?

You’ve been told by a HVAC technician that it’s time to replace your furnace. How do you know that this is correct? Is it time to schedule a heating system installation vancouer wa? You don’t want to replace too early, but you also don’t want to wait until your furnace is no longer working. Here are some basic guidelines to help you determine if it’s time to replace your furnace.


How old is your furnace? If you furnace is 15-20 years or older it may be a good idea to investigate replacement options. The older furnaces are less energy efficient and have a shorter life than the newer furnaces. In fact, newer furnaces can last between 20-30 years. A big factor in the life span of your furnace is regular maintenance. Have you been scheduling an maintenance with a heating and air conditioning vancouver wa company every year? If not, your furnace may not last as long.


Are you having to repair your furnace frequently by a heating and air conditioning vancouver wa company? Are the repairs expensive? We recommend using the 50% Rule if you are having frequent and expensive furnace repairs. If the cost of repairs is 50% or more of the cost of a new furnace, you should consider replacement. The 50% Rule applies to the furnace no matter it’s age. Give us a call to schedule a free heating system installation vancouver wa quote if your cost of repairs is 50% or more of the cost of a furnace.


Furnace and heating technology has improved greatly. If you are wanting to get better efficiency out of your furnace and save money on your utility bills, replacement may be your best option.  According to the U.S. Department of Energy, older furnaces are only are 56%-70% energy efficient while new furnaces can be up to 98.2% energy efficient. The rating for gas furnace efficiency is called AFUE. AFUE shows the amount of gas it takes to heat your residence. If a furnace is 70% AFUE, this means that 70% of the gas is used to heat your home and 10% is wasted. In effect, for every dollar you spend on heating 70 cents is used for heating and 30 cents has gone to waste.  This inefficiency and waste can add up over time. If you are wanting to improve efficiency, make sure to get a new furnace that is Energy Star certified; ask your local heating and air conditioning vancouver wa company, which furnaces are Energy Star certified.


Improving the comfort in your home may be a reason to replace your furnace. Old furnaces can be inefficient in evenly heating the home. In addition, they can be loud and dirty. Consider replacing your furnace if you are experiencing:

  • hot or cold spots in your home
  • humidity problems in the home
