How Long Does It Take to Replace a Furnace & When to Replace It?

A furnace that needs replacing

When the sub-zero temperatures arrive in Minnesota, we all look forward to a warm, cozy home where we can put up our feet and relax. But what if your furnace is heading toward the great white light? Like many appliances, how long a furnace will last and when to replace it depends a great deal on the extent of its use, and the last thing you want to deal with is a furnace breaking down when the harshest Minnesota winter temperatures hit.

The majority of homeowners are not completely aware of their furnace’s age, the extent of its use, or how long a furnace lasts. What are the signs your furnace may need replacing? This post walks you through what you need to know about when to replace a furnace.

How Long Does It Take to Replace a Gas Furnace?

The amount of time it takes to replace a furnace depends on many different factors, including the skill of the installer, the size of your home and the type of furnace you are planning to replace, but it usually takes between 4 to 10 hours.

If you’re a Minnesotan replacing your furnace with a similar model, the ducts will be in the correct alignment and installation should be smooth. The energy efficiency can alter the ductwork, so if you want to go with a more energy efficient model that is newer than your previous furnace, the installation may take longer. When considering the size of your new furnace, you will need to evaluate the size of your home. The larger your home, the larger your furnace, and the larger your furnace, the longer it takes to install it, but if you install a furnace that is too small, it may not last due to overexertion.

When considering an installer, you want one with experience who will point you in the right direction of a furnace that adapts well to your home while optimizing energy efficiency. A furnace that will increase energy efficiency, lower your energy bills, and last for years to come will likely take longer to install. With Sedgwick Heating, you can count on skilled installers that will minimize downtime and install your furnace in the shortest time possible.

How Long Does a Furnace Typically Last?

The average lifespan of a gas furnace is approximately 15-20 years. This doesn’t mean that a 15-year-old model should be scrapped tomorrow, but it does give you an idea of the amount of service the furnace has behind it and a better indication of whether replacement is a better option than repair in the future.

If you are unaware of the age of your furnace and when to replace it, you can find the manufacturer serial number on the inside of the furnace cover. Simply note the number and contact a heating professional to get a manufacturing date. If you discover that you are approaching or past the 15-year mark and have put a significant amount of repair into your furnace already, it may be time to consider a replacement.

What Does the Age of Your Furnace Mean?

Understanding the age of your furnace is important in making proper judgments in handling issues your furnace may have, but the sheer age of your system does not indicate a need for replacement alone. If you have a 20-year-old furnace that still works well, you have a superior model that will most likely hold strong. However, there are still some things to keep in mind.

Regular Maintenance

No matter the age of your furnace, regular maintenance by a professional is guaranteed to keep it working in the best condition possible. Plus, working on it regularly has its perks, you’ll have a better idea of when to replace your furnace, your air filters will be kept clean, ventilation and fan systems will be inspected, and repairs will be addressed before they become serious.

Make Note of Your Furnace Model

If you have a long withstanding furnace that does end up needing replacement, you may want to invest in the same or similar model that is simply more updated. A sturdy, reliable furnace model is going to be the best investment for your heating system — and in Minnesota, it’s worth it.

Signs Your Furnace’s End Is Near

Discovering your furnace needs replacing after it has completely shut down is less than desirable. Keeping an eye out for warning signs that your furnace has seen better days is going to be your best bet to keep your costs low and prevent your family from freezing while you wait for a replacement. Here are some of the most common signs your furnace needs replacing:

  • A large rise in energy bills
  • Uneven heating
  • Low air quality
  • Frequent repairs

My Furnace Needs Replacing. Now What?

If your furnace has been inspected, repaired, inspected again, and simply won’t work the way it needs to, it’s time for a new one. Where do you start? As mentioned, if you have a model that has proven itself to be durable over time, consider a newer version of the same model. While the upfront investment may seem high, newer versions of furnaces have a lot of perks in comparison to their older counterparts.

Modern furnace models are built with an annualized fuel utilization efficiency (AFUE) rating that represents the efficiency of each model. This represents how much heat the furnace can create versus how much is lost in the combustion process. A standard gas furnace will have a rating of 80% or higher, with some top of the line units maintaining a rating of up to 98%. The higher the efficiency, the lower your heating costs.
