Should You Repair or Replace Your Furnace?
Deciding between furnace repair and replacement is crucial for Portland homeowners. Use this guide to make the best choice:
Consider Repair If:
- Furnace is less than 10 years old
- Repair cost is under $1,500
- Single component failure
- System has been reliable
- Current AFUE rating is 90%+
- Only minor issues present
Consider Replacement If:
- Furnace is 15+ years old
- Repair cost exceeds $1,500
- Frequent breakdowns (3+ repairs/year)
- Rising energy bills (20-30% increase)
- Uneven heating throughout home
- Yellow or flickering pilot flame
The $5,000 Rule for Portland Homeowners
Formula: Multiply repair cost by furnace age. If the result exceeds $5,000, replacement is recommended.
Example: If repair costs $500 and your furnace is 12 years old: $500 x 12 = $6,000. Since this exceeds $5,000, replacement makes financial sense for long-term value.

How much does furnace replacement cost in Portland?
Furnace replacement in Portland ranges from $3,495 to $8,000 depending on efficiency rating (80-98% AFUE), size requirements, and installation complexity. Standard efficiency furnaces (80% AFUE) cost $3,495-$4,500. High efficiency (90-95% AFUE) cost $4,500-$6,500. Ultra-high efficiency (96-98% AFUE) cost $6,500-$8,000. Energy Trust rebates and financing options are available to help reduce costs.
When should I replace my furnace vs repair it in Portland?
Consider furnace replacement if your system is over 15 years old, repair costs exceed $1,500, you're experiencing frequent breakdowns (3+ per year), energy bills are rising 20-30%, you have uneven heating, or notice a yellow pilot flame. Use the $5,000 rule: multiply repair cost by furnace age - if over $5,000, replace. Modern high-efficiency furnaces can reduce heating costs by 20-40% in Portland's climate.
What rebates are available for furnace replacement in Portland?
Portland homeowners may qualify for Energy Trust of Oregon rebates ranging from $350-$800 for high-efficiency furnaces. Federal tax credits provide up to $600 for ENERGY STAR certified equipment. NW Natural also offers rebates for qualifying systems. Some manufacturers offer additional rebates of $100-$300. We handle all rebate paperwork for you and help maximize your savings.
How long does furnace replacement take in Portland?
Most residential furnace replacements in Portland are completed in 1 day (6-10 hours). This includes removal of the old furnace, installation of the new unit, gas/electrical connections, venting installation, system testing, and homeowner training. Complex installations requiring ductwork modifications or electrical upgrades may take 1-2 days.
What size furnace do I need for my Portland home?
Portland homes typically need 35,000-50,000 BTU for smaller homes (under 1,500 sq ft), 50,000-70,000 BTU for medium homes (1,500-2,000 sq ft), and 70,000-100,000 BTU for larger homes (2,000+ sq ft). Proper sizing depends on square footage, insulation, ceiling height, and Portland's mild Pacific Northwest climate. Our NATE-certified technicians perform Manual J load calculations to determine exact requirements.
What's the difference between 80%, 90%, and 95% AFUE furnaces?
AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a furnace converts fuel to heat. An 80% AFUE furnace converts 80% of fuel to heat (20% lost through venting). A 95% AFUE furnace converts 95% to heat (only 5% waste). For a Portland home spending $800/year on heating, upgrading from 80% to 95% AFUE saves approximately $150 annually. High-efficiency furnaces also provide quieter operation, better humidity control, and qualify for Energy Trust rebates.
Do you offer financing for furnace replacement in Portland?
Yes, we offer flexible financing options with approved credit including 0% APR for 60 months on qualified furnace purchases. We also help you access all available rebates and incentives including Energy Trust of Oregon rebates, NW Natural rebates, federal tax credits (up to $600), and manufacturer rebates.
