AC Installation in Melbourne, FL: Sized for Your Home, Not a Formula
A 1,100-square-foot Eau Gallie cottage off the Indian River and a 2,800-square-foot two-story in Suntree need different systems, different SEER2 targets, and often different duct conversations. Florida Air works in both. We run a proper load calculation on every Melbourne job and use that number, not the tonnage on whatever just came out, to size what goes in.

When Melbourne Homeowners Are Ready for a New System
Melbourne's mix of housing eras creates a predictable pattern: older Eau Gallie and 32901 homes hit system-replacement age at the same time their ductwork needs attention; Suntree and Heritage Isle homes are dealing with aging 2000s-era equipment on the tail end of its useful life. Here is what we see most often when the replacement conversation comes up.
Original Equipment from the 1990s or Earlier
The large-lot 1990s homes in Windover Farms and the older sections of Suntree (Camelot, Wedgewood) are hitting 25 to 30 years on their original systems. At that age you are also dealing with R-22 refrigerant, which has not been manufactured since 2020. Recharging an R-22 system means sourcing expensive reclaimed refrigerant for equipment that is already past its practical life. The replacement conversation usually makes more sense than another recharge.
Condenser Fins Visibly Corroded
If your outdoor unit sits within a mile of the Indian River or the Eau Gallie River and you can see the aluminum fins on the condenser starting to pit or crumble, the unit is losing efficiency and the damage gets worse each season. Coil coating can slow further corrosion on a newer unit, but on a system that is already 12 or more years old with visible damage, the installation conversation is the right one. A coastal-coated replacement condenser will last significantly longer in that location.
The Upstairs Never Cools Down in July
Two-story Suntree and Baytree homes with attic air handlers are the most common source of this complaint. Long flex duct runs through an attic that can exceed 130 degrees in summer bleed the cooling out of the air before it reaches your upstairs vents. A new variable-speed system paired with a duct audit and targeted insulation improvement addresses this directly. A like-for-like swap of just the equipment rarely solves a thermal envelope and duct problem.
Running Below the Current SEER2 Minimum
Florida's new minimum for residential AC installation is 15 SEER2 (the updated efficiency rating that replaced SEER in 2023). If your current system was installed before 2015, it is likely rated at 13 SEER or lower. For a Melbourne home running the AC eight to nine months per year, the efficiency gap between an older 13 SEER unit and a modern 15 or 16 SEER2 system shows up noticeably on your FPL bill over a full cooling season.
Condensate Overflows or Ceiling Stains
Attic air handlers in Heritage Isle, Viera East, and Baytree homes that are 15-plus years old sometimes have undersized or missing float switches on the secondary drain pan. Melbourne's summer dew points regularly hit 72 to 74 degrees, which means the system pulls a lot of moisture out of the air. When the primary condensate drain clogs and no float switch shuts the system down, that overflow goes somewhere. If you have seen ceiling stains near your upstairs vents or a hall closet, that is often condensate, not a roof issue. A new installation includes proper float switch and drain setup.
How Florida Air Handles a Melbourne Installation, Start to Finish
From the first call to the walk-through on installation day, here is what the process actually looks like.
In-Home Load Calculation, Not a Guess
We come to your Melbourne home, measure the conditioned square footage, check insulation depth, count windows, note which direction your walls face, and run a Manual J load calculation. That number is what we use to size the equipment. If the system coming out was oversized, we tell you. Oversizing is one of the most common install mistakes in Florida, and it costs you in humidity control every day the system runs.
System and SEER2 Recommendation
Florida Air installs ComfortMaker and Ruud as our primary lines. For most Melbourne homes, a 15 or 16 SEER2 system is the practical sweet spot. For larger two-story Suntree or Baytree homes where the system runs hard all summer, we will show you the variable-speed option and the real numbers on payback. We check FPL rebate eligibility at this stage so you are looking at actual net cost. You pick the system; we give you honest information to do it.
Installation Day: What Actually Happens
The crew arrives, protects your floors, and pulls the old equipment. New equipment goes in, electrical and drain connections are made, then we pull a deep vacuum on the refrigerant line set before charging it. That vacuum step confirms there are no leaks in the lines before refrigerant goes in. If duct rework is on the scope, that work happens in the same visit. Most Melbourne replacements are done the same day. We clean up before we leave.
Startup, Registration, and Walk-Through
Once the system is running, we verify airflow and temperatures at the vents, check that the condensate drain and float switch are working, and set up the thermostat. We register the manufacturer warranty in your name on the spot. Before we leave, we walk you through the thermostat, explain the maintenance schedule, and answer any questions. You know what you have and what to do next.
Melbourne Installations by Neighborhood and Housing Era
Every Melbourne ZIP has a different housing profile, and the install conversation looks different depending on which one you are in.
In Eau Gallie (32935) and downtown Melbourne (32901), the stock runs from 1920s bungalows in the Eau Gallie Arts District up through 1970s and 1980s slab ranches in Honeybrook Plantation and Pebble Creek. Most of these homes have air handlers in interior hall closets or garage closets. The install conversation here almost always includes a duct assessment because the flex runs and original trunk work in 1950s and 1960s homes frequently need updating before a new unit performs the way it should.
In Suntree and Baytree (32940), the homes are larger, typically 1,800 to 3,500 square feet, two-story, with attic air handlers. The older Suntree sections (Camelot, Wedgewood) date from the late 1970s and early 1980s and are now on their second or third system. Viera East and Heritage Isle are seeing 2000s-era original equipment reaching the end of its useful life. These installs involve attic platform work for the air handler, longer refrigerant line runs, and careful attention to return-air sizing on the upper level.
Windover Farms (32934) has large-footprint 1990s homes on one-acre-plus lots, many with dedicated mechanical rooms and R-22 systems that are now past their practical service life. The replacement conversation in this corridor is straightforward: the system has run its course, and the ductwork is generally still in better shape than in older ZIPs.
Why Melbourne Homeowners Call Florida Air for New Installs
We work in Eau Gallie every week. We know Suntree attic layouts. Here is what actually matters when you are putting a new system in.
NATE-Certified Installation, Not Just Sales
NATE certification (North American Technician Excellence) means the technician who installs your system has been independently tested on the skills that matter for correct installation: refrigerant charge, airflow measurement, electrical connections, and startup verification. It is not a sales credential. Florida Air holds license CAC1823291 and carries full insurance. The person who comes to your home in Melbourne is credentialed on the actual work, not just the paperwork.
We Do the Load Calc. We Do Not Skip It.
An oversized system short-cycles: it turns on, hits the temperature setpoint fast, shuts off, and never runs long enough to pull the humidity out of the air. In Melbourne's summers, that leaves your home feeling sticky and clammy at 76 degrees even when the system is technically "working." The Manual J load calculation takes 20 minutes and prevents that problem before the equipment goes in. We do not skip it and we do not let the existing equipment size make the decision for us.
Close to Melbourne, Familiar with Its Homes
Florida Air's shop is in Palm Bay, about 8 to 10 minutes from Holmes Regional Medical Center and the Eau Gallie corridor. We are not staging from Rockledge or Orlando. The drive matters on estimate day and on installation day. And because we work in Melbourne regularly, we know the mechanical room setup in a Windover Farms ranch versus an attic air handler install in a Suntree two-story. That background changes what we bring and how long the job takes.
On coastal coil selection: If your home is within about a mile of the Indian River Lagoon or the Eau Gallie River, the brackish humidity off the water accelerates aluminum fin corrosion on uncoated condensers faster than most owners expect. When we spec a replacement for a lagoon-side 32935 home, we factor that into the coil selection. It is not an upsell. It is the right call for that location.
