Frequently asked questions
How much does it cost to replace an air conditioner in Miami?
Central air conditioning replacement in Miami generally costs $4,000 to $7,500 installed, covering equipment and labor. Simple swaps on an existing, well-sized duct system fall toward the low end, while larger homes, higher-efficiency equipment, or added duct and electrical work push toward $7,500.
Do I need a furnace in Miami, or is a heat pump enough?
Miami is in climate zone 2, the warmest zone, so most homes are cooling-dominated and a heat pump handles the limited heating demand on its own. A heat pump runs $6,000 to $12,000 installed here, versus $7,500 to $13,000 for a full AC-plus-gas-furnace system, so the all-electric route is usually both simpler and cheaper.
Do I need a permit to replace an HVAC system in Miami?
Yes — HVAC changeouts require a mechanical permit, and permit fees in this area typically run $75 to $400 depending on the scope of work and jurisdiction. Your contractor normally pulls the permit and folds the cost into the quote, so ask whether it is included in the price you were given.
Are there rebates for a new HVAC system in Miami?
Duke Energy Florida offers an HVAC rebate through its Smart $aver program, with amounts that vary by system type and efficiency level. Check with your own electric utility first, since rebate eligibility depends on who serves your address, and confirm the equipment you are quoted meets the efficiency tier before you sign.
Are HVAC contractors in Miami required to be licensed?
Yes. HVAC contractors in Florida are licensed by the Department of Business and Professional Regulation (DBPR), either state certified or registered at the county level. Ask for the license number and verify it with DBPR before scheduling work, and confirm the contractor carries liability and workers' compensation coverage.
