❓ Frequently Asked Questions
How much does ductwork replacement cost for a 2,000 sq ft home?
For a typical 2,000 sq ft US home, ductwork replacement costs $7,000-$12,000 on average. This includes materials ($3,500-$6,000), labor ($2,500-$4,500), permits ($300-$800), and disposal of old ducts ($500-$1,200). Your exact cost depends on region, material choice, and complexity - use our calculator above for a personalized estimate.
Is it cheaper to replace ductwork or repair it?
Minor repairs cost $300-$1,000. However, if your ducts are over 15 years old, poorly sealed, or causing high energy bills, replacement often pays for itself within 5-7 years through energy savings. New ducts can reduce HVAC costs by 20-30% annually. For extensive damage (>50%), replacement is more cost-effective than repairs.
How long does ductwork last in US homes?
Quality ductwork lasts 15-25 years with proper maintenance. Galvanized steel lasts longest (25+ years), while flexible ducts may need replacement sooner (10-15 years). Signs you need replacement include: high energy bills (20%+ increase), uneven temperatures, visible damage, poor air quality, and ducts over 15 years old.
Does new ductwork increase home value?
Yes! New ductwork improves HVAC efficiency, indoor air quality, and comfort - all selling points for home buyers. You can expect to recoup 50-70% of the cost in increased home value, plus enjoy lower energy bills while you live there. Energy-efficient ductwork is a major selling point in today's market.
What type of duct material is best for homes?
Galvanized steel is most durable (25+ years) and fire-resistant, costing $10-$15 per linear foot. Flexible ducts are easier to install and cheaper ($4-$8/ft) but last 10-15 years. Insulated flexible ducts offer better energy efficiency ($7-$12/ft). Fiberglass duct board provides excellent sound absorption ($8-$12/ft). Your choice depends on budget, longevity needs, and local climate.
How do I calculate how much ductwork I need?
A typical home needs 1 linear foot of ductwork per 6-8 sq ft of floor space. For a 2,000 sq ft home, you'll need approximately 250-330 linear feet of ducts. Our calculator above automatically calculates based on your home size, type, and system selection. It also accounts for regional factors and material choices for accurate pricing.
