When It's Time to Replace in Melbourne

Melbourne is not one neighborhood, it is five housing eras strung along the Indian River from downtown's 1940s bungalows to Viera's new-construction two-stories off Wickham. Each one reaches the end of the road in its own way. Here is what we actually see when a system is done being repaired and it is time to plan a replacement.

In the Eau Gallie corridor and the EGAD cottages in 32935, we are working the oldest housing in the Melbourne metro, with a median build year back in the 1960s. A lot of these slab ranches still have their original galvanized steel supply trunks, which rust and pinhole inside the plenum, and the air handlers sit in interior hall or garage closets. When one of these systems reaches replacement age, the honest job is the equipment and the deteriorated ductwork together, not just swapping the box and leaving the new system to push air through rotted metal.

Downtown Melbourne and the historic core in 32901 run smaller 1940s-to-1970s bungalows and block homes, many with original unlined duct and some on package units or mini-split retrofits. Over on the riverfront in 32935, within a mile of the Eau Gallie River and the Indian River Lagoon, the brackish humidity pits the fins on uncoated condensers, and we have seen corrosion shorten the replacement cycle to as little as four to six years. Once that pitting is advanced, cooling capacity falls off and a coastal-coated replacement is the honest fix.

Then there is the newer stock. The 1990s Windover Farms homes in 32934 and the 2000s systems out in Heritage Isle and Suntree are hitting the 25-to-30-year wall now, and many still run R-22 refrigerant that is no longer made. The two-story Suntree, Baytree, and Viera homes in 32940 run attic air handlers with long oversized flex runs, so a lot of their summer performance loss is the ductwork, not the box. When one of those reaches replacement age, we plan the whole job so the new system is not fighting the same attic it always has. Melbourne is right next door to us, and knowing these specific homes is the difference between a swap and a real replacement.

What's Included in Your Melbourne System Replacement

A replacement is more than dropping in a new box. Here is exactly what a Florida Air whole-system replacement covers, spelled out so there are no surprises.

  • Right-sized equipment via a load calculation. We run a Manual J load calc on your actual home instead of matching whatever was there before, so the new system fits your square footage, insulation, windows, and ductwork.
  • Matched indoor coil and air handler. The outdoor unit, indoor coil, and air handler are matched as a set so the system runs at its rated efficiency, not a mismatched pairing that never performs.
  • New or flushed line set. We install a new refrigerant line set, or fully flush and pressure-test the existing one when it is sound, so old oils and contaminants do not foul your new compressor.
  • New thermostat. A new thermostat matched to the equipment, set up and explained before we leave.
  • Permit and Brevard County inspection. We pull the county permit and schedule the inspection so your install is documented and code-compliant.
  • Safe haul-away of the old system. We remove and responsibly dispose of your old equipment and recover the refrigerant. Nothing gets left in your yard.
  • Manufacturer warranty registration. We register the manufacturer warranty in your name so the coverage is actually active, not something you find out was never filed.
  • Install brands you can choose from. ComfortMaker and RUUD are our primary install brands, with Lennox available on premium upgrades. We walk you through the trade-offs for your home.

Repair or Replace? What We Tell Melbourne Homeowners

We are not going to talk you into a new system you do not need. The rough rule we actually use is simple: look at the age of the equipment and the cost of the repair. If your system is past about 12 years old and the repair runs close to half the cost of a new one, replacement usually wins, because you are spending real money on equipment that still has aging parts everywhere else. If it is younger and the fix is small, we tell you to repair it and move on.

The other big one in Melbourne is R-22, and it shows up most in the 1990s Windover Farms homes in 32934 and the 2000s systems out in Heritage Isle. Those are hitting the 25-to-30-year wall, and if the system still uses R-22 refrigerant, that refrigerant is no longer made and recharging a leak means paying for reclaimed refrigerant on old equipment. When we see an R-22 system with a leak, we are honest that a replacement is usually the smarter spend, and we show you why rather than just asserting it.

If you already have a quote from someone else and it does not sit right, get a second opinion before you sign. We do that for free, and we would rather tell you your system has good years left than sell you something you do not need. You can read more about how we think through it in our repair vs replace guide, or just request a free second opinion.

What Goes Into Your Price

Every Melbourne home is a little different, so the honest answer to "what does it cost" is "it depends on a few things." Here is what actually moves the number, so you know what you are paying for.

System size and tonnage

The Manual J load calculation tells us the right tonnage for your home. A larger Suntree or Baytree two-story needs more capacity than a small Eau Gallie ranch, and the size of the system is one of the biggest drivers of cost. We size it right rather than overselling tonnage you will pay to run.

Coastal coil upgrades in 32935

If your home is on or near the Eau Gallie River or the Indian River Lagoon in 32935, a coastal-coated coil resists the brackish-air pitting that eats uncoated fins in four to six years. It adds to the cost, but on the water side of Melbourne it protects the investment, and we tell you honestly whether your address warrants it.

Duct repair and galvanized replacement

A lot of 1960s Eau Gallie and EGAD homes still run original galvanized supply trunks that have rusted through, and the newer attic-duct two-stories lose 20 to 30 percent through leaky flex. If yours needs duct correction to let the new system breathe, that is factored in, because a right-sized unit on failing ductwork never performs the way it should.

Efficiency and SEER2 choice

A higher-efficiency SEER2 system costs more up front and less to run every summer, which adds up on the larger Viera and Suntree homes with heavy cooling runtime. We lay out the options for your home and budget so you can decide where the trade-off makes sense, rather than steering you to the priciest tier.

A new system does not have to be paid all at once. We offer financing through our lending partners so you can spread the cost over time. Ask us about the current options when you call, or see our financing options.

For real price ranges by system type, see our cost guide. And before you buy, check whether your new system qualifies for an FPL rebate of up to $550 on high-efficiency equipment.

Melbourne AC Replacement FAQs

Real questions from Melbourne homeowners planning a new system, answered straight.

We look at three things with you: the age of the equipment, what a repair costs against the value of the system, and whether the failure is a sign of more to come. A rough rule we use is that if the system is past about 12 years old and the repair runs close to half the cost of a new one, replacement usually makes more sense. The other big flag we see in Melbourne is R-22 refrigerant, especially in the 1990s Windover Farms homes and the 2000s systems out in Heritage Isle that are hitting the 25 to 30 year wall. If your system still runs on R-22, that refrigerant is no longer produced, so a recharge with reclaimed refrigerant gets expensive and it is money spent on equipment near the end of the road anyway. We give you both numbers and the honest reasoning, then you decide. No pressure.
In the older Eau Gallie cottages and EGAD-area homes in 32935, the original galvanized steel supply trunks often develop rust perforation inside the plenum, and that contaminates the supply air and drives up static pressure. Homeowners usually blame the unit when the duct is the actual failure point. So the honest answer is that it depends on what we find. If the equipment still has good years left, we may only need to address the ductwork. If the system is also aging, we plan the replacement and the duct correction together so the new equipment is not pushing air through rotted galvanized. We look at your specific home and tell you which it is, rather than selling you both by default.
Almost always it is the ductwork and the returns, not a system that is too small. Those two-story Suntree, Baytree, and Viera homes run attic air handlers with long oversized flex runs that barely contact the drywall, and a 20 to 30 percent efficiency loss is typical up there in a hot attic. Adding tonnage does not fix that, it just makes the unit short-cycle so it never runs long enough to pull humidity out. We run a Manual J load calculation on your actual home, then we look at the return path and the duct condition before we ever reach for more capacity. If the upstairs is starved, the fix is usually air distribution, not a bigger box.
Yes. Every system replacement we do in Melbourne is pulled under a Brevard County permit and passes a county inspection when we are done. That is not an extra we upsell, it is how the work is supposed to be done and it protects you. A permitted install means the equipment, the electrical, and the condensate handling all get checked by the county, and it keeps your manufacturer warranty and your homeowner's insurance clean. We take care of the paperwork, schedule the inspection, and register the manufacturer warranty in your name so the coverage is actually active, not something you find out later was never filed.
The only honest answer is that it depends on your home, and we figure it out with a Manual J load calculation rather than guessing off square footage or matching whatever was there before. A 1960s Eau Gallie ranch with settled R-11 attic insulation and a single hall-closet return has a very different load than a Suntree two-story with attic ducts. We measure the space, factor in your insulation, windows, sun exposure, and duct condition, and size the system to match. A right-sized unit runs longer, quieter cycles, pulls out more humidity in our 76 to 78 percent summers, and costs less to run than one that is oversized and short-cycling.
If your home is on or near the Eau Gallie River or the Indian River Lagoon in 32935, yes, we treat a coastal-coated coil as standard rather than an upsell. The brackish lagoon humidity pits the fins on uncoated aluminum condensers, and we see corrosion shorten the replacement cycle to as little as four to six years on the water side. It is not full ocean intensity like the barrier island, but it is meaningful. For rinsing, the industry guidance we follow is a quarterly coil rinse within about a mile of any salt water body and annual within one to three miles. Inland homes out toward Viera in 32940 carry a much lower salt load, so we will tell you honestly where your address falls.
