• 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.
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.
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.
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.
