How to hire a contractor in Marietta
Hiring a contractor for HVAC installation in Marietta requires verifying licensing, insurance, and references.
Verify licensing
Georgia does not require a state GC license; counties may require local registration.
Check insurance
Always request a Certificate of Insurance (COI) naming you as additional insured. Minimum $500,000 general liability is standard; $1 million is preferred.
Get structured bids
Request 3 itemized bids. Bids should reference the contractors license number, insurance, and warranty terms.
Read the contract
Standard payment schedule: 10% deposit, milestone-based progress payments. Never pay more than 50% before substantial work begins. Most jurisdictions allow 3-business-day cancellation for at-home contract signings.
Financing your project in Marietta
Most Marietta homeowners finance renovation projects with a mix of cash, home equity, and dealer financing.
Home equity options
Mariettas median home value of $380,000 means most homeowners with a few years of equity have $76,000 to $152,000 of tappable equity. HELOCs and home equity loans are typical funding sources for projects above $20,000. HELOC rates trend in the 8-9% range as of 2026.
Personal loans
For projects under $30,000, an unsecured personal loan often makes more sense than a HELOC because closing costs and timeline dont favor home equity for smaller jobs. Personal loan rates run 9-15% depending on credit.
Local rebates and incentives
Georgia Power offers rebates for ENERGY STAR-rated upgrades. Combined with federal IRA tax credits, total subsidies can reach $1,500-$5,000 on qualifying projects.
0% dealer financing
Cabinet manufacturers, window companies, and flooring retailers often promote 0% promotional financing for 12-24 months. Read the fine print — interest is typically deferred (not waived).
