Planning estimate only, not a contractor quote. Built from Home Cost USA modeled national unit costs for hvac replacement, and adjusted for job complexity (×1.00). No validated local cost adjustment is applied, so this is a national planning benchmark rather than a local price. Scope assumed: Mid-efficiency system with new coil, line-set work, and permits.

Estimate your own hvac replacement

Hiring a plumbing & hvac contractor in Florida

Collect at least three itemized written bids for the same scope. Bids that differ by more than about a third usually describe different work, not different value, check material grade, prep, and warranty before you compare totals.

Ask who pulls the permit. In most jurisdictions the licensed contractor pulls it, and a contractor who asks you to pull it as the homeowner is shifting liability onto you.

Verify license and insurance status yourself with the appropriate Florida state agency before signing. Home Cost USA does not verify licenses, and no company on this page is endorsed or vetted by us.

Never pay the full amount up front. Tie payments to milestones and keep the final payment until the work passes inspection and your punch list is complete.

Questions to ask before you hire

Comparing bids only works when every bid covers the same scope. Ask each contractor the same questions and write the answers down.

1Did you perform a load calculation to size the system, or match the old tonnage?
2Are the coil, line set, thermostat, and permit included in this price?
3Will you test airflow and static pressure after installation?
4Can you send an itemized written estimate that separates labor, materials, and permit fees?
5Is your business licensed for this work in my state, and can you share your license and insurance certificates?
6Who will be on site day to day, and are they employees or subcontractors?
7What is your written warranty on labor, and how long does the material warranty last?
8What is your payment schedule, and how much do you require up front?
9What would cause the price to change once work starts, and how are change orders approved?
10How will you protect the rest of my home, and who handles cleanup and disposal?
