The heating system in your home is like an old friend. This trusty system has stuck with you through thick and thin, helping you weather the coldest of winters. Unfortunately, even the closest, most dependable of friends are no match for the stresses of time. Eventually, there will come a day when your furnace will need to be replaced.

If your heating system has just reached its 25th birthday, you may be wondering if the time for an upgrade is soon approaching. As a homeowner, it’s understandable if you aren’t familiar with when to replace furnaces. These HVAC systems are specifically designed to last a long time, so there’s a good chance you haven’t had to replace your furnace yet.

So, should you replace a 25-year-old furnace? We’ll answer this question and more below!

How Long Does a Furnace Last, On Average?

When it comes down to it, the average lifespan for a furnace is 15 to 25 years. Of course, the life expectancy of these heating systems can depend on various factors, such as the type of fuel they run on and whether or not you schedule regular maintenance. With all things considered, your furnace isn’t likely to see more than 30 years of life.

So, should you replace a 25-year-old furnace? When you ask HVAC professionals this question, you’re likely to receive an unwavering “yes.” If your furnace has been operating for more than 20 years, there’s a good chance the system has lost some of its efficiency. You’re also likely to encounter more issues with the heating system as it ages — such as costly repairs — that disrupt your comfort and waste precious time.

Furnace Age & Efficiency

Hopefully, you now understand that you should replace a 25-year-old furnace with a new, energy-efficient model. But why is efficiency so important?

As your furnace ages, it can experience regular wear and tear. This damage can make it difficult for your heating system to complete its job. As a result, the furnace will need to work twice as hard to warm your home. In the end, you can find yourself dealing with higher energy bills or hot and cold spots in your living spaces.

How efficient is a 20-year-old furnace? All-in-all, you can expect the heating system to be considerably less efficient than newer models. If you’re unsure when to replace furnaces, consider taking a look at your energy bills. If the cost doesn’t seem to equate with your heating system usage, then it might be time to schedule a heating replacement.

Signs Your Furnace Needs Replacing

As we’ve mentioned, knowing when to replace furnaces can be challenging for homeowners. Fortunately, there are a few warning signs you can look out for to help you determine whether or not it’s time for an upgrade.

Poor Heating

Is your furnace failing to keep up with your heating needs? Are you feeling cold spots throughout your home? These can be some of the most obvious signs that your furnace has reached the end of its useful life.

Frequent Repairs

Are you constantly calling a professional technician to repair your heating system? If so, it might be time for a furnace replacement in Fresno, CA. Repair costs can add up over time — especially if your furnace keeps breaking down and needing the assistance of an expert.

If you’re unsure whether to repair or replace your furnace, take a look at the system’s age and repair history. Suppose your unit is more than 15 years old and needs frequent furnace repairs. If this is the case for you, replacing the system can be the most cost-effective solution.

Strange Noises

It’s important to pay attention to any strange, loud noises your furnace might be making. This is especially true if you have a gas furnace. When a heating system makes unusual sounds, this is usually a clear indication that something is wrong.

If you have a gas furnace, a rattling sound can indicate that the heat exchangers are cracked. You’ll want to address this problem as soon as possible to prevent a serious problem, such as carbon monoxide leaking into your home. If your furnace is old, needs frequent repairs, and makes loud noises, a replacement could be the best option. You’ll want to talk to an HVAC technician to discuss your options.
