When to Repair or Replace Your Furnace
At Squeaks Plumbing Heating & Air in Denver, CO, we understand that deciding whether to repair or replace your furnace can be a tough call. After all, your furnace is the heart of your home during those chilly Denver winters! So, letโs dive into some key factors that will help you make the best decision for your comfort and your wallet.

1. Age of the Furnace
The first thing youโll want to consider is the age of your furnace. Now, hereโs the dealโmost gas furnaces are built to last around 15 to 20 years, while electric furnaces can hang in there for up to 30 years with proper care. But how do you know how old your furnace really is?
Look for a sticker or label on the unit that shows the installation or manufacture date. If thatโs not visible, jot down the model and serial numbers and give us a callโwe can help you figure it out! If your furnace is getting up there in age, especially past that 15-20 year mark for gas units, it might be time to start thinking about a replacement.
2. Condition of the Furnace
Letโs talk about the condition of your furnace. If youโve been keeping up with regular maintenance (and we hope you have!), your furnace should be running smoothly with just the occasional need for a repair. But if maintenance has been a bit of an afterthought, your furnace might not last as long.
Take a peek at your furnaceโdo you see any rust or corrosion? Thatโs a red flag that it might be time to start considering a new unit. Remember, a well-maintained furnace should last its full lifespan, but neglect can cut that time short.
3. Frequency of Repairs
Hereโs a question we often ask our customers: How often has your furnace been acting up lately? If youโve had to call us for repairs more than once in the past year or two, thatโs a sign that your furnace might be on its last legs.
Even if the individual repairs donโt break the bank, those costs can add up over time. Instead of pouring money into frequent fixes, it might be smarter (and less stressful) to invest in a new furnace that will give you peace of mind.
4. Cost of Repairs vs. Replacement
Letโs get down to the nitty-grittyโmoney. When faced with a repair, you should weigh the cost of that repair against the cost of replacing your furnace. A good rule of thumb is the 50% rule: If the repair costs more than half the price of a new furnace, itโs probably time to replace.
Or, you can use what we call the “5000 rule.” Multiply the estimated repair cost by the age of your furnace. If the result is over 5000, replacing is usually the smarter choice. For example, a $500 repair on an eight-year-old furnace gives you 4000โnot too bad. But that same repair on a twelve-year-old furnace gives you 6000, which means itโs likely time for a new furnace.
5. Energy Efficiency Considerations
Furnaces arenโt getting any youngerโor more efficient. Older furnaces just donโt perform as well as todayโs models, which means they use more energy (and cost you more on your heating bills).
Take a look at your current furnaceโs efficiency rating and compare it to the newer models. You might be surprised at how much you could save by upgrading to a more efficient unit. Plus, with energy costs always on the rise, those savings can add up quickly!
6. Performance, Comfort, and Safety
We know how important it is for your home to feel just right. If your furnace isnโt keeping your home as warm as it used to, or if youโre noticing cold spots, poor air quality, or even dryness in the air, your furnace might not be performing at its best anymore.
Safety is another biggieโespecially when it comes to something as serious as a cracked heat exchanger, which can lead to dangerous carbon monoxide leaks. If youโve got any concerns about safety, itโs definitely time to think about a replacement.
