Common Jacksonville HVAC emergencies
Call Now — (844) 582-179524/7 dispatch · Jacksonville-area network
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. The most common cause is electrical (capacitor, contactor) or refrigerant — both require a technician.
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 immediately and call 911 first.
Water dripping from vent or air handler
Water from a ceiling vent · pooling near the indoor air handler · drain pan overflowing. The #1 cause in humid Jacksonville summers is a clogged condensate drain line — clearing it requires working around the evaporator coil and is a technician task.

Jacksonville's hot-humid climate & your HVAC
This is a strongly cooling-dominated Zone 2A (Hot-Humid) climate — AC runs 8–10 months of the year and humidity management is a year-round design consideration. Federal SEER2 14.3 (Southeast Region) minimum applies to new equipment.

HVAC in Jacksonville, 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
Jacksonville International Airport (KJAX) is the NOAA reference station for the city. Per the NOAA NCEI U.S. Climate Normals 1991–2020 (station USW00013889), Jacksonville records an annual mean temperature of 69.3°F, approximately 2,803.2 annual cooling degree days against only 1,227.6 heating degree days, a striking 53.40 inches of annual precipitation, and zero snowfall. The 2.3:1 CDD-to-HDD ratio defines Jacksonville as a strongly cooling-dominated Zone 2A hot-humid climate — with the additional design factor of Atlantic coastal exposure, which accelerates salt-air corrosion of outdoor condenser coils.
U.S. Census ACS 2022 5-Year
The U.S. Census Bureau ACS 2023 5-year estimates (Tables B25040 and B25035 for Jacksonville city, Florida) report 384,741 occupied housing units with a median year built of 1986. Heating-fuel distribution is extraordinary: 94.5% electricity (363,470 units) overwhelmingly dominates, with only 3.1% utility natural gas (11,949 units). Jacksonville is effectively a pure-electric heating market — heat pumps that handle both the large annual cooling load and the modest winter heating demand are the standard system architecture across virtually the entire housing stock.
Florida Legislature
Every HVAC contractor working in Jacksonville 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 are “unlimited in the execution of contracts” covering central air conditioning, refrigeration, heating, and ventilating systems; Class B contractors are “limited to 25 tons of cooling and 500,000 Btu of heating in any one system.” For typical Jacksonville residential work, a Class B contractor is fully qualified. Permit fees for residential mechanical work are set by the City of Jacksonville Building Inspection Division under Municipal Code of Ordinances Chapter 320; contact the division directly for the current fee schedule.
JEA
Jacksonville is served by JEA (Jacksonville Electric Authority), a municipal electric, water, and sewer utility. Per the JEA Residential Rebates page, current HVAC-related rebates include: heating and cooling system $200 rebate; smart thermostat $50 rebate; attic insulation $200 rebate; heat pump water heater $350 rebate (JEA notes an ENERGY STAR-certified HPWH saves a four-person household approximately $550/year on electric bills). Natural-gas customers are served by TECO Peoples Gas, which administers separate rebates for the 3.1% of Jacksonville homes using gas heat. The federal Section 25C tax credit was terminated for installations after Dec 31, 2025 (OBBBA, P.L. 119-21) — the local incentives above remain active for 2026.
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). State HEAR rebates and utility programs remain in effect. See our HVAC financing options for what's still available.
