Do You Need a New Furnace?

Here in Lakewood and throughout the state of Colorado, the winter months bring along bitterly cold weather. But, with a furnace that’s in good condition, you can keep your home cozy. After all, what’s better than coming in from the outdoor chill to your warm, inviting home? 

That said, furnaces don’t last forever. If you’ve been living in your home for over a decade, you’re likely approaching the need for a new furnace. A furnace replacement is a significant expense, making it crucial to understand the right time to get a new furnace. 

Let’s go over the signs that you should get a new furnace. Whether due to age or damage, replacing your furnace may be necessary to keep your home heated and comfortable. 

How Long Should a Furnace Last?

The lifespan of a furnace can vary depending on its manufacturer, among other factors. But, the average furnace should last for 15 to 20 years – if it’s properly cared for, that is. Maintenance is important to preserve the life of your furnace, so make sure to keep up with your furnace’s ongoing needs. Your Lakewood HVAC experts can make any necessary furnace repairs to help you avoid the need for an early furnace replacement. 

Furnace Repairs vs. Replacement

It can be hard to tell whether repairing or replacing your furnace is the right choice. Repairs are usually the most affordable option upfront. But, if a furnace replacement is in your near future, it’s likely more cost-efficient to invest in a new furnace sooner. By replacing your furnace sooner rather than later, you won’t be wasting money on repairs for a furnace that’s nearly at the end of its life, anyway. 

Signs That You Need a New Furnace

Rising Energy Bills

If your furnace is old, it won’t run as efficiently as it used to. It will use more energy to provide the same amount of heat for your home. So, if your energy bill is significantly higher than usual during the cold weather months, take a look at your furnace. It may need to be replaced to preserve the energy-efficiency of your home’s HVAC system. 

Yellow Flames

A natural gas furnace that’s in good condition will have defined blue flames. Yellow flames may be a sign that your furnace’s burner or heat exchanger should be cleaned. But, yellow flames can also escalate into gas leaks and a necessary furnace replacement. So, if you see yellow flames in your furnace, contact your Lakewood furnace repair experts immediately. We’ll address the yellow flames and fix the issue before it becomes worse.


As aforementioned, once your furnace has reached its full lifespan, it’s time for a replacement. Your furnace will start to wear out over time and eventually won’t function properly. Using an old furnace can be dangerous and presents several risks to your home, including the risk for a carbon monoxide leak. Additionally, using an old furnace will lower your home’s air quality, which may trigger respiratory problems for members of your family. 

Don’t take the risk of using a furnace that’s past its expiration date. A new furnace is an investment in the safety of your home and the health of your family.

Poor Heating Consistency

When the furnace is running, does your home seem to be warm in some rooms and cold in others? Inconsistent heating could be a sign that your furnace isn’t properly distributing hot air around your home. If the furnace is also nearing the end of its lifespan, it may need to be replaced. 


Corrosion and other types of damage to the outside of your furnace is a definite sign that you need a replacement. Damage to your furnace can be a serious danger to your home, so be sure to have it looked at by our Lakewood furnace repair team ASAP. 

Excess Noise

If your furnace is louder than usual when it’s operating, you should have it looked at by an HVAC expert. It may simply need repairs. But, often when a furnace is nearing the end of its lifespan and becomes noisy, a full replacement is the way to go.
