Melbourne Weather and HVAC Load
In a normal year, Melbourne racks up 501 heating and 3,401 cooling degree days (NOAA 1991-2020 normals). 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 2 nights at or below freezing and 76 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 | 501 |
|---|---|
| Cooling degree days / year | 3,401 |
| Nights at or below 32°F | 2 |
| Days above 90°F | 76 |
| Average low / high | 63.4°F / 82.4°F |
Melbourne Housing Stock
Half the homes in Melbourne were built before 1984 (Census ACS median), so the typical house is about 42 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Melbourne has roughly 22,000 owner-occupied homes, or 60.3% of households. The median home value is $272,900, and median household income is $64,504. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 10 hail days and 41 days with damaging thunderstorm winds in Brevard 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. Brevard County also had 8 tornado days in that period. In Melbourne, 22.6% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.
When It Makes Sense
- The house can't reach the thermostat setting on hot afternoons
- It still runs on R-22 refrigerant
- The AC is 12 to 15 years old or more
- Summer electric bills keep going up
What Moves the Price
- Tonnage, based on house size and local climate
- SEER2 rating and whether the compressor is single-stage or variable-speed
- Whether the coil and line set also need replacing
- The pad, permit and refrigerant (R-410A or the newer R-454B)
- Electrical work such as a new disconnect, breaker or wiring
We raised the national figures about 13% for Melbourne 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
- Removing the old condenser and coil
- Refrigerant charge and a leak test
- Startup, an airflow check and warranty registration
- The electrical disconnect and wiring
- The new condenser, coil and, if needed, line set
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 Melbourne. 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
- Buy the condenser and coil as a matched set, or you may void the manufacturer warranty.
- Ask for a Manual J calculation. "Same size as the old one" isn't sizing.
- Fall and early spring installs often come with better pricing and shorter waits.

AC Installation Questions from Melbourne Homeowners
How much is new AC installation in Melbourne?
Plan on $4,800 to $10,800, with most jobs near $8,100. 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 Melbourne?
Between late fall and early spring. With 76 days over 90°F, Melbourne 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.
