When Should A Furnace Be Replaced

Understanding When To Replace Your Furnace

Determining when to replace your furnace is a complex decision based on one clear indicator or a single obvious sign. When your furnace is nearing the end of its life, it will let you know. Your furnace will send out some distress signals to make sure you’re paying close attention to the state of its working order. Learn what to look for when your furnace is aging and the factors your should consider when debating furnace replacement


Furnace Replacement Alert: Age 

The age of your furnace is down on paper and in ink. If you know that your furnace was installed more than 15 years ago, you should start saving up for a new one. Most furnaces should indeed last between 15 and 30 years, but at the 15-year mark is when repairs start to creep up. 


Furnace Replacement Alert: Bills

If you have lived in your home for more than a few years, you should be aware of the average heating and cooling cost at any given time of the year. Unusual increases in expenses should be a red flag for your furnace. If your use hasn’t changed, but your heating bill has, it is a clear indicator that your furnace is reaching the end of its life.


Furnace Replacement Alert: Efficacy 

Your furnace should maintain the temperature inside your home with ease. If you find that your thermostat is far off the mark, you should be concerned about the efficacy of your furnace. Schedule a diagnostic evaluation and see what the issue is. If your furnace is not operating at maximum productivity, consider a replacement.


Furnace Replacement Alert: Noises

That part in Home Alone when the furnace says “Kevin” is not quite what you will be looking for; however, your furnace may alert you with knocking and plinking sounds, along with some ominous rattling. If you have children in the home, they will be the first to alert you of these sounds. Sounds coming from your furnace are a tell-tale indicator that something is wrong. 


Furnace Replacement Alert: Gas

If your furnace is leaking CO2, replace it immediately. A damaged combustion chamber could leak carbon monoxide putting you and your family in grave danger. If your furnace is leaking CO2, replace it immediately. Frequently check for carbon monoxide leaks by keeping a carbon monoxide detector in the home near the furnace and look for the presence of the following:

  • Excess moisture 
  • Absence of upward draft 
  • Black streaks 
  • Yellow not blue burner flame 
  • Flu-like symptoms 


Furnace Replacement Alert: Decisions 

When you are making big life decisions, like choosing to retire or making plans to sell your home, you may also want to consider replacing the furnace in your home at the same time. If aging in place, you will benefit from a high-functioning heat source critical to your health. You can also reap the benefits of utility and tax credits after installation. If you plan on selling your home, touting a new furnace as a selling point can increase market value.
