Duval County HVAC property data.
Duval County, Florida is coterminous with the City of Jacksonville under a 1968 consolidated charter—the only fully consolidated county-city government in Florida—giving it a single property record base of roughly 406,000 taxable parcels covering 874 square miles. At 1.02 million residents it is the sixth most populous county in the state, with a mid-market median owner-occupied home value of $286,300 (ACS 2023 5-year) and a homeownership rate of 58.2%, reflecting both a large institutional-investor rental footprint and a housing stock built predominantly before 1990.

What the data shows for HVAC in Duval County.
Jacksonville sits in IECC Climate Zone 2A—hot and humid—with 2,803 annual cooling degree days against only 1,228 heating degree days, making cooling loads more than twice those of heating and elevating latent (humidity) removal as a primary HVAC design driver. The 1986 median build year means most of the county's residential HVAC fleet has already turned over at least once; current replacements must meet Florida's 15 SEER2 minimum for Zone 2A equipment under post-2023 federal standards, raising average installed cost. With 58.2% homeownership, the owner-decision base is substantial.
