If your aging furnace has been struggling to keep up this season, it could be nearing the end of its lifespan. Even though winters in Chandler can be relatively mild, our cold desert nights can still put your furnace to the test—and the last thing you want is a breakdown when you need heat the most.
If you’re trying to decide whether it’s time for a new furnace, consider both your current comfort and the long-term benefits of a newer, more efficient system. A furnace replacement can help you stay warm now and save on energy costs over the years.
Here are 4 signs that it may be time to replace the furnace in your Chandler, AZ home:
- Your Furnace Is Getting Older
Most gas furnaces run reliably for 10 to 15 years, while electric and oil models can sometimes last up to 25 years. Skipping its annual maintenance, though, can wear a furnace down faster than expected.
Even if your furnace is under 10 years old, repairs can keep it running a little longer. But eventually, repeated issues make replacement unavoidable—and a new furnace saves headaches down the line and provides dependable heating now.
- Frequent or Costly Repairs
If your furnace isn’t blowing warm air or isn’t as strong as it should be, minor fixes like changing the filter or a tune-up might help. But if major parts (such as the heat exchanger) need repair or replacement, the cost can be significant. Our expert HVAC technicians can help you weigh which option is the smarter long-term choice.
The 50% Rule: A helpful rule of thumb to follow is the 50% rule. If your furnace is 10-15 years old or older, and a needed repair costs more than half the price (50%) of a new unit, a replacement is usually the wiser choice. At this point, you’re often better off investing in long-term reliability rather than patching up an aging system.
- Persistent Heating Problems
Think back to how your furnace performed last winter—and how it’s been holding up so far this season. Has it been acting up? Problems such as short-cycling, uneven heating, or blowing lukewarm air often point to worn or failing parts. When these issues keep returning despite repairs, your home’s warmth can feel unpredictable and uncomfortable.
If the same problems persist despite repairs, replacing your furnace can give you steady heat that you don’t have to worry about.
- Rising Energy Costs
Another sign your furnace may be wearing out is a history of unexplained high energy bills. A professional inspection can help you decide whether repairs are worthwhile—or if a newer, more efficient system could save you money on energy while keeping your home comfortable.

Why Furnace Replacement Can Be the Smarter Choice
While a quick repair might temporarily get your furnace running, it often doesn’t address underlying issues. A full replacement ensures your home stays comfortably warm now and provides dependable, efficient heating for years to come.
In this way, a furnace replacement isn’t just a planned expense—it’s an investment in your peace of mind.
