Geothermal for the Ormond Beach house that is tired of losing its outdoor unit
The 1960s ranch in Tomoka Oaks has replaced its outdoor unit twice since 2022, once for Ian and once for salt. There is a system with no outdoor unit at all.
The house that keeps losing its condenser
Ormond Beach’s housing stock explains why geothermal gets a hearing here when it does not in most of Florida. The early-1960s homes around the old Tomoka Oaks course sit on low river land that went under in Ian and again in Milton. The 1950s cottages of Ormond-by-the-Sea and the estate homes along the Halifax breathe salt air every day. The condenser on a ground-level pad beside those houses is the single most exposed thing the homeowner owns, and some have replaced theirs twice in three years.
A geothermal heat pump has no condenser. It rejects summer heat into the ground through a buried water loop and pulls winter heat back out the same way. Everything mechanical is inside the house, where the flood water, the salt spray and the falling oak limbs cannot reach it. That is the problem it solves in this town, before any talk of efficiency.
The efficiency is real, too
The ground a few feet down in Volusia County stays near 72 degrees all year. An air-source heat pump on a 95-degree August afternoon is trying to dump heat into air hotter than the house; a geothermal unit is dumping it into 72-degree sand. The result is the lowest operating cost of any system we install, quiet operation because the only fan is indoors, and a loop with a lifespan measured in decades. The federal tax credit for geothermal was historically the most generous of any HVAC incentive, and it closed for systems placed in service after December 31, 2025, so it no longer enters the comparison.
Tiers and configurations, without the model numbers
- Closed-loop horizontal. Pipe laid in trenches a few feet down across the yard. The cheapest loop when the lot is large enough, which the older golf-course and riverfront lots usually are.
- Closed-loop vertical. Pipe dropped into bored holes. Costs more per ton but fits the smaller mainland lots in Rio Vista and Ormond Terrace, and avoids digging up a mature landscape.
- Open loop on a well. Possible in west Volusia on private wells, but Floridan-aquifer water is hard and often carries iron and sulfur, which scale and foul the heat exchanger. We rarely recommend it here.
- Indoor unit tiers. Single-stage, two-stage and variable-capacity units, exactly as with air-source heat pumps. The two-stage and variable units dehumidify better over a long humid summer and are what we quote for most homes.
- Hot water assist. Most units can pre-heat domestic hot water with waste heat from cooling, which in a nine-month cooling season is a meaningful side benefit.

Installation notes for sandy, wet ground
Trenching in Ormond Beach is easier than in clay country and wetter than almost anywhere. The crew expects water in the trench by mid-afternoon and plans the loop laying around it. Vertical bores need a drilling rig and a yard the rig can reach. The indoor unit goes where the air handler was, often the garage, and ties into the existing ductwork after we have sealed and, if needed, resized it. Permits run through the City of Ormond Beach or Volusia County depending on the address, and the loop is pressure-tested before anything is buried. Expect a few days of yard work and one day of mechanical work; the house keeps its old system running until the morning of the changeover.
Care
A geothermal system needs the same indoor attention as any heat pump: filter changes, a clear condensate drain, and a coil kept clean in a mold-prone climate. The loop itself needs a check of antifreeze concentration and loop pressure once a year, which we fold into the maintenance visit. There is no outdoor coil to rinse, no cabinet to corrode and no pad to raise. For the riverfront and beachside households that have had enough of the alternative, that is the whole appeal.

Geothermal questions from Volusia homeowners
Is there enough yard for a ground loop on a Tomoka Oaks lot?
Usually. The 1960s golf-course lots there are large enough for a horizontal loop; smaller mainland lots in Ormond Terrace need vertical bores, which cost more but need only a corner of the yard. We measure and tell you which before the quote.
Does the high water table help or hurt?
It helps. Wet sand moves heat far better than dry sand, so a loop in Ormond Beach’s saturated ground performs better than the same loop would inland. The trench crew just has to work around it.
Can the ground loop be damaged by a flood?
No. The loop is sealed plastic pipe buried below the surface, and the indoor unit sits in the house. Water over the yard does nothing to it, which is exactly the point for the riverfront streets.
What happens to the system if the power goes out in a storm?
The same thing that happens to any electric system: it stops until the power returns. The difference is that there is no outdoor unit to be knocked over, flooded or struck by a limb while it waits.
