AC out, blowing warm, or iced over
Outdoor unit silent · indoor blower running but warm air · ice on the refrigerant lines · short-cycling on/off. Possible causes range from electrical parts (capacitor, contactor) to a refrigerant problem — both need a technician to diagnose.
Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup. If you smell gas, leave the building right away without flipping switches or using phones inside, then call 911 or your gas utility’s emergency line from outside.
Water dripping from vent or air handler
Water from a ceiling vent · pooling near the indoor air handler · drain pan overflowing. Typical causes of condensate overflow include a clogged or dislodged drain line, a cracked or corroded drain pan, a failed condensate pump, and a dirty filter that lets the coil freeze (ACCA). Turn the thermostat off to limit water damage and call a technician.

Miami had an estimated 489,812 residents on July 1, 2025. In Miami, the median home was built in 1978 with a current median value of $475,200. Around 31% of homes are owner-occupied. About 3% of households heat with natural gas vs. 91% electric. The Florida grid averages $0.16/kWh.

HVAC in Miami, FL: local data & sources
Every numerical claim below references a federal, state, or municipal primary source — NOAA climate normals, U.S. Census ACS, the Florida licensing authority, and your local utility's published rebate program.
NOAA NCEI 1991–2020 Normals
Miami International Airport (KMIA) is the NOAA reference station for the city. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00012839), Miami records an annual mean temperature of 77.4°F, approximately 4,656.0 annual cooling degree days against only 103.6 heating degree days, 67.41 inches of annual precipitation, and essentially zero snowfall. The 45:1 CDD-to-HDD ratio is extreme even among Southern metros — Miami is effectively a pure-cooling HVAC climate where heating requirements are negligible, and equipment specifications should prioritize cooling capacity, humidity control, and hurricane-wind resistance above all else.
U.S. Census ACS 2023 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for Miami city, Florida) report 190,282 occupied housing units with a median year built of 1978. Heating-fuel distribution is extraordinary: 91.2% electricity (173,542 units) dominates, with only 2.7% utility natural gas (5,096 units) and 5.4% reporting no fuel used. Miami is essentially a pure-electric heating market — a function of both climate (the occasional 50°F night is trivial heating load) and building history. Heat pumps that provide cooling year-round and occasional heating in the December–February shoulder months are the standard system architecture across virtually the entire Miami housing stock.
Florida Legislature
Every HVAC contractor working in Miami must hold a current Florida Certified Air Conditioning Contractor license, administered by the Florida Department of Business and Professional Regulation (DBPR) Construction Industry Licensing Board (CILB). Per Florida Statutes Section 489.105, the two license classes are strictly defined: Class A contractors have “services unlimited in the execution of contracts requiring the experience, knowledge, and skill to install, maintain, repair, fabricate, alter, extend, or design... central air-conditioning, refrigeration, heating, and ventilating systems, including duct work in connection with a complete system.” Class B contractors are “limited to 25 tons of cooling and 500,000 Btu of heating in any one system” — essentially residential and light commercial. For a Miami homeowner, a Class B contractor is fully qualified for any typical residential job; the Class A designation matters when the project scope exceeds 25 tons (rare outside large multi-family). Verifying a contractor’s active Class A or Class B license before authorizing work is the critical due-diligence step. Permit fees for residential mechanical work are set by the City of Miami Building Department; contact the department directly for the current fee schedule.
Florida Power & Light
Miami is served by Florida Power & Light (FPL). Per the FPL Save Money programs page: “Buy a new energy-efficient A/C and receive an instant $200 rebate,” and “earn an instant $220 rebate when you upgrade your ceiling insulation.”
Miami-Dade County’s building code imposes requirements that don’t apply elsewhere in Florida — let alone the rest of the country. Miami-Dade and Broward counties are designated as the High-Velocity Hurricane Zone (HVHZ) under Chapter 16 of the Florida Building Code. The practical HVAC consequence: “Mechanical equipment, appliances and supports that are exposed to wind shall be designed and installed to resist the wind pressures determined in accordance with the Florida Building Code.” For Miami homeowners, this means outdoor condenser units must be secured to wind-load-rated pads or wall brackets, and any new installation requires HVHZ-rated mounting hardware — a detail that adds $200–$500 to installation cost compared to non-coastal installs but is non-negotiable under city code.
The federal Section 25C Energy Efficient Home Improvement Credit was terminated for installations placed in service after Dec 31, 2025 by the One Big Beautiful Bill Act (Public Law 119-21). Check your state energy office and utility for current rebate programs. See our HVAC financing options for what's still available.
