Home improvement costs vary dramatically by state. A roof replacement in California costs 40% more than in Mississippi.
The most common questions homeowners search before starting a project — answered directly.
The average cost is $5,700 to $16,000 for a 1,500–2,000 sq ft home using asphalt shingles. Metal roofing runs $10,000–$30,000. Labor is ~60% of cost, which is why California costs 40%+ more than Mississippi for identical work.
HVAC replacement costs $4,800 to $12,500 on average in 2026. Central AC alone: $3,500–$7,500. Full HVAC (furnace + AC): $6,000–$12,000. Heat pumps: $5,500–$10,500 installed.
For most homeowners, yes. Average system: $15,000–$30,000 before incentives and $10,500–$21,000 after the 30% federal tax credit. Most save $900–$2,800 annually with payback in 6–12 years.
Labor is 50–65% of most costs and varies dramatically. A San Francisco electrician charges $100–$180/hour; rural Arkansas runs $45–$75/hour. Cost of living, union rates, and contractor demand all drive regional differences.
Start with a referral, then verify license and insurance independently, then get 2–3 additional quotes. Verify license numbers directly with your state contractor board. Never pay more than 10–30% upfront.
