Above the last high-water mark: Charles Springs River Estates, Suwannee River Park Estates and the Mobile Estates
Everyone who owns on the river knows the number: the gauge reading the night the water came into the yard. We build to that number, not to the code minimum.
The short answer: above the last high-water mark
If you own on the river and you are replacing or relocating equipment, here is the whole rule in one sentence: the condenser’s electrical compartment and the air handler both go above the highest water you have personally seen on the lot, plus a margin, and nothing we install goes in a space that has ever been wet. The rest of this page is why, and what it looks like in the three river communities closest to Live Oak.
Three river communities, three kinds of house
Charles Springs River Estates is two-acre riverfront lots and the stilt and river houses that go with them: main floor a full story up, parking and storage beneath, decks facing the water. Owners here mostly understand elevation already. What they often inherit is an air handler in a ground-level closet, installed when the house was new and the river was being polite.
Suwannee River Park Estates has no deed restrictions, and it shows in the best way: site-built cabins, manufactured homes, a few serious year-round houses, and weekend places that have been added onto for forty years. Equipment is everything from window units to a modern heat pump, and the pads range from a foot off the ground to sitting in the sand.
Suwannee River Mobile Estates is an owned-land manufactured-home community a little back from the water. Package units and belly ducts are the norm, and the flood question is the yard holding water after a ten-inch night rather than the river itself.
Stilt houses and the air handler under the floor
The classic river-house mistake is a perfect stilt home with the air handler in a closet at ground level, because that was the easy place to put it when the house went up. The river has flooded the under-house level of homes from Suwannee Springs down to Branford in Debby in 2012, again in 2024, and in Helene the same year. Each time, the air handlers in those closets were ruined.
Our fix is to bring the air handler up to the living level, usually horizontal in a hallway ceiling or in a utility closet on the main floor, and run the condenser up on a steel platform at deck height. The under-house space stays what it should be on a river lot: a place for the boat and nothing with a circuit board.
After the water goes down
When the river has been in a yard, the order of operations matters. Do not turn the system on to see if it works. Call, and we will do these in sequence:
- Kill power at the breaker and the disconnect before anyone touches the unit.
- Open the condenser’s electrical compartment and the air handler cabinet and look for the silt line. Where it sits tells us what survived.
- Test the capacitor, contactor, compressor windings and blower motor dry, before power.
- Check the duct. Belly ducts and under-floor runs that took water are usually a replacement, not a cleaning.
- Decide, with you, whether this is a flush-and-restart, a parts repair, or the moment to relocate and replace.

River lot questions
My cabin's air handler is in a closet under the stilt house. Is that fixable without rebuilding?
Usually. We move the air handler up to the main floor or into a horizontal position in the ceiling, and bring the duct with it. The old under-house closet becomes storage you don’t mind losing to the river.
The water never actually reached my condenser, just the pad. Do I need to raise it anyway?
If it reached the pad once, it will reach the compressor eventually. A stand or pedestal that puts the unit’s electrical compartment above the known line costs a fraction of a flooded condenser, and we do it at replacement time for almost nothing extra.
We only use the place on weekends. What should the thermostat be doing when we're gone?
Running, not off. A closed cabin on the river with the system off will grow mold in a week in July. Set it high, around 80 to 82, with a Wi-Fi thermostat that texts you if the temperature or humidity climbs, and let it cycle.
Can you work on a mobile home's package unit the same as a house system?
Yes. The manufactured homes in Suwannee River Mobile Estates mostly run package units or small splits with belly ducts, and we service, repair and replace all of them. The duct under the floor is often the real problem, and we inspect it on every visit.

We set equipment height from what the water actually did, and we come any hour.
