Miami-Dade County HVAC property data.
Miami-Dade County — county seat Miami — is Florida's most populous county at 2,838,461 residents (ACS 5-year) and the most densely parceled, with more than 1.1 million taxable parcels carrying a total assessed value of $471.5 billion as of the 2024 preliminary certification by Property Appraiser Pedro J. Garcia. The median owner-occupied home value of $547,200 (ACS 5-year) sits roughly 80% above the US median, driven by coastal premium, international capital concentration, and a large non-homesteaded ownership class that distinguishes Miami-Dade from every other Florida county. At 52.2% owner-occupancy among occupied units — below the state average — the county supports one of the largest investor-owned residential bases in the southeastern US, creating layered demand across every property-services vertical.

What the data shows for HVAC in Miami-Dade County.
Miami-Dade County is classified as IECC Climate Zone 1A — Very Hot, Humid — the most cooling-intensive residential zone in the continental US. NOAA's 1991-2020 climate normals for the Miami Beach station (USW00092811) document 4,187 annual cooling degree days (base 65°F) and only 138 heating degree days, meaning HVAC systems run almost exclusively for cooling on a year-round basis. With a median housing vintage of approximately 1978, a substantial portion of the owner-occupied stock carries equipment installed well past the standard 15-20 year replacement lifecycle. The 52.2% owner-occupancy rate concentrates replacement demand in roughly 509,000 households where the owner bears maintenance and replacement costs directly.
