Why Colorado Furnaces Work Harder
Cold winters mean:
• Longer heating cycles
• More stress on components
• Greater expansion and contraction of metal parts
Homes in Thornton, Brighton, Westminster, and surrounding cities often run their furnaces heavily from November through March.
What Impacts Furnace Lifespan?
Key factors include:
• Annual professional maintenance
• Correct system sizing
• Clean filters
• Proper venting
• Quality of original installation
Well-maintained systems may reach or exceed 20 years. Poorly maintained systems often fail sooner.

When Replacement Is Smart
Consider replacement if:
• The furnace is over 12 years old
• Efficiency is below 80% AFUE
• Repair costs are increasing
• Energy bills keep rising
New high-efficiency systems (90%+ AFUE) can significantly reduce heating costs in Colorado’s climate.
What Does Replacement Cost in the Metro Area?
Most furnace replacements in the Denver metro range from $5,500 to $11,000 installed.
Higher efficiency systems may qualify for rebates and federal tax credits, lowering overall cost.
Can You Extend Furnace Lifespan?
Yes.
• Schedule annual inspections
• Replace filters every 1–3 months
• Address small issues before they grow
Proactive care is almost always less expensive than emergency breakdowns.
