Deciding whether to replace or repair your current furnace takes a lot of consideration. But you won’t like to be in a situation wherein you will have to make a rush purchase because your furnace broke down completely. 

To guide you in figuring out when to replace your furnace, here are some indicators that might help you decide if you need to replace your furnace.

  • When your furnace has passed the 10-year mark, its efficiency will start to deteriorate. The following years of your furnace will incur a lot of system failure since its average lifespan is 12 to 15 years. 
  • If a furnace or OKC HVAC requires frequent repair, it is reasonable to replace it with a new unit rather than to continue keeping up an inefficient and failing furnace system.
  • If your furnace no longer provides sufficient warmth inside the room, you may buy a new furnace that is suited to the size of your house. 
  • A significant increase in energy bills means an inefficient furnace. Newer models have better efficiency with 97 percent Annual Fuel Utilization Efficiency (AFUE), which allows you to save on your energy bill.
  • If you noticed strange and loud noises coming from your furnace, you better call your trusted HVAC contractor to immediately resolve the problem since it may be a sign of an emergency. 

Factors to consider in buying a new furnace

After you’ve decided that it is high time to change your current furnace unit, things must be considered when purchasing a new one. To ensure that you’ll buy the furnace suited to your needs, check the following customer guidelines.

  • Furnace Fuel Type

There are fuel options that you can choose to power your furnace: electricity, natural gas, and oil and propane. It’s essential that you know what fuel type is available in your area. A natural gas furnace may be costly initially but less expensive to operate. While an electric furnace promises higher efficiency at a low cost, it might be an uneconomical choice compared to other types.

  • Furnace Efficiency

AFUE ratings are used to gauge the efficiency of the furnace. A higher AFUE rating means higher efficiency. The minimum AFUE rating allowed to be in the market is 78 AFUE. It signifies that 78 percent of the fuel used to power the furnace will be converted into usable heat—currently, the most efficient furnaces in the market offer 95 to 98 AFUE.

  • Furnace Size

It is essential to consider the size of the space you want to heat in buying a new furnace since a bigger space requires a bigger furnace unit. Aside from the size of your house, you also have to consider the climate in your area and other factors about heat loss and airflow. You may ask an HVAC contractor to give you professional advice about the right size suited to your house. 

  • Furnace Installation

The gas furnace is the most common type of furnace among homeowners, but the installation requires special venting and fuel pipes. So, if you use a different fuel source or your furnace system needs an upgrade, it is best to make changes in the system.
