Frequently Asked Questions
How much does a new furnace cost installed?
Furnace installation costs $2,500-$8,000. Basic 80% efficiency units run $2,500-$4,000. Mid-efficiency 90%+ furnaces cost $4,000-$6,000. High-efficiency 95%+ modulating furnaces range from $6,000-$8,000 installed.
How long does a furnace last?
Gas furnaces last 15-20 years, oil furnaces 15-25 years, and electric furnaces 20-30 years. Annual maintenance extends life. Warning signs: yellow burner flame, unusual noises, uneven heating, frequent cycling, and increasing energy bills.
Is a high-efficiency furnace worth the extra cost?
High-efficiency furnaces (95%+) cost $1,500-$3,000 more but save $200-$400/year on gas bills. Payback period is 5-10 years. Worth it in cold climates with high heating costs. They also require only PVC venting, which is cheaper than metal flues.
What size furnace do I need?
Size by square footage and climate: 30-60 BTU per sq ft depending on location. 1,500 sq ft home needs 60,000-90,000 BTU. 2,500 sq ft needs 100,000-120,000 BTU. Proper sizing is critical; oversized furnaces cycle too frequently.
