Jacksonville Weather and HVAC Load
NOAA's 1991-2020 climate normals put Jacksonville at 943 heating degree days and 3,302 cooling degree days per year. Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. A normal year brings 4 nights at or below freezing and 96 days over 90°F. On the cooling side, a 2,000 sq ft house here usually needs around 4 tons. A tight, well-insulated house may get by with half a ton less.
| Heating degree days / year | 943 |
|---|---|
| Cooling degree days / year | 3,302 |
| Nights at or below 32°F | 4 |
| Days above 90°F | 96 |
| Average low / high | 62.9°F / 79.9°F |
Jacksonville Housing Stock
The median Jacksonville home dates to 1986, according to the Census ACS. That makes the typical house about 40 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 57.4% of occupied homes, roughly 221,000 households. With a median household income of $66,981 and a median home value of $266,100, local labor rates come out near the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 16 hail days and 72 days with damaging thunderstorm winds in Duval County. The largest hail reported was 2 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Duval County also had 7 tornado days in that period.
When It Makes Sense
- The house can't reach the thermostat setting on hot afternoons
- It has had more than one refrigerant leak
- It still runs on R-22 refrigerant
- Summer electric bills keep going up
What Moves the Price
- Whether the coil and line set also need replacing
- SEER2 rating and whether the compressor is single-stage or variable-speed
- Tonnage, based on house size and local climate
- Electrical work such as a new disconnect, breaker or wiring
- The pad, permit and refrigerant (R-410A or the newer R-454B)
We raised the national figures about 13% for Jacksonville using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover
- The new condenser, coil and, if needed, line set
- Removing the old condenser and coil
- Startup, an airflow check and warranty registration
- The electrical disconnect and wiring
- Refrigerant charge and a leak test
Florida Permits, Efficiency Rules and Rebates
Florida is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Expect the contractor to pull a mechanical permit for a replacement job in Jacksonville. If a bidder suggests skipping it, move on. Also ask for a Florida license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Fall and early spring installs often come with better pricing and shorter waits.
- Ask what federal, state or utility incentives apply to the model you're quoted.
- Buy the condenser and coil as a matched set, or you may void the manufacturer warranty.

AC Installation Questions from Jacksonville Homeowners
How much is new AC installation in Jacksonville?
Plan on $4,700 to $10,700, with most jobs near $8,000. Equipment efficiency, house size and the condition of the ducts and wiring decide where your quote falls.
When is the best time to schedule new AC installation in Jacksonville?
Between late fall and early spring. With 96 days over 90°F, Jacksonville contractors are booked solid all summer, and off-season jobs are easier to schedule and negotiate.
What size AC do I need?
It depends on square footage, insulation, windows and climate. The rough rule is a ton for every 450 to 650 sq ft, but only a Manual J calculation gives you a real number.
How long does a new AC last?
With yearly maintenance, 12 to 17 years. Salt air and extreme heat shorten that.
