Ninety-four degrees above ground, seventy-two below it: geothermal on Suwannee County acreage
Inland heat is the whole case for geothermal here. The air hits 94 with no breeze; a few feet underground it never gets close. A short answer first, then the long one.

The short answer for a Suwannee County lot
If you own land, geothermal works here and works well. The ground under Suwannee County sits at a constant low-70s temperature year round, which is a far better place to dump heat in July than 94-degree air, and a far better place to pull it from in January than a 28-degree morning. A ground-source heat pump trades the noisy outdoor unit for a loop of buried pipe and runs quieter, cheaper and longer than anything with a fan in the yard. The catch is the cost of putting the loop in the ground, which is why it suits a one-acre lot in Eagle’s Pointe or Savannah Plantation, a farm homestead toward Dowling Park or Wellborn, or a new build on acreage far better than a city lot downtown. Cook’s installs them. Keep reading for how the pieces fit.
Why the ground here does the work the air can’t
Live Oak’s climate is the argument. Summer highs sit in the mid 90s with dew points in the 70s and no sea breeze; this is the hottest stretch of the state in July. An air-source heat pump or air conditioner has to push heat out of the house into air that is already nearly as hot as the refrigerant. Every degree the outdoor air climbs, the system works harder and delivers less. Then in winter the same machine has to pull heat out of 30-degree air during a cold snap, and it leans on electric strips to do it.
The ground does not have those swings. A few feet down, below the layer that bakes and freezes, Suwannee County soil and the limestone beneath it sit near the year’s average temperature, within a few degrees whether it is August or January. Water in the Floridan aquifer under the county is in the same range. A loop of pipe carrying water through that ground delivers a constant, mild heat sink in summer and heat source in winter. The heat pump indoors sees the same conditions every day of the year, so it is sized smaller, runs at a steadier rate and pulls humidity out of the house for longer stretches, which is exactly what a 72-degree dew point requires.
Loop types on local ground
- Horizontal loops need open ground: trenches several feet deep across a wide area. On an acre with a septic drainfield and a well already in place, the loop goes where those are not, and we map all three before a machine shows up.
- Vertical loops use bored holes a few hundred feet deep and a small footprint, which suits a tighter lot but costs more per ton. This county’s karst geology, the same limestone that opens sinkholes after heavy rain, is a drilling consideration, and the driller’s read on the site is part of the estimate.
- Pond or open-loop systems come up on river properties and farms with a stocked pond. They have their own permitting and water-quality questions, and the iron and sulfur in local groundwater make open-loop designs something we approach carefully [[CONFIRM WITH JERRY]].

Five things that set the quote on a Live Oak loop
There is no price on this page because no honest one exists before someone has walked the property. What moves the number:
- The loop field. Horizontal is cheaper than vertical; soil that trenches easily is cheaper than rock; a long run from the field to the house adds pipe and pumping.
- The size of the load. A tight new house in Savannah Plantation needs fewer tons than a 1970s ranch with original windows. Insulation and air sealing done first can shrink the whole system.
- The indoor side. Whether the existing ductwork tests well or needs replacement, and whether the mechanical space has room for the indoor unit and the flow center.
- Hot water. A desuperheater that uses waste heat for domestic hot water is a modest add that pays off fast in a house where the system runs five months a year.
- Site logistics. Access for a trencher or a rig, restoring the lawn or pasture afterward, and coordinating with a well or septic contractor if anything has to move.
The estimate is free and written, and it covers all five. A loop system qualifies for the same installment plan as any other new system. Utility incentives for geothermal are thin in this market; FPL’s rebate program is built around conventional high-efficiency air conditioning and flows through enrolled contractors, with Cook’s enrollment status [[CONFIRM WITH JERRY]]. There is no federal credit to add in. We would rather you hear that from us than from an accountant in April.
Scheduling a job that takes a drill rig
Geothermal is not a one-day changeout. The sequence usually runs: site visit and estimate; loop design and any permits; the loop contractor’s day or days on the property; then Cook’s crew on the indoor side, which goes much like a conventional install and typically finishes in a day. Weather matters more than it does for a split system, since a trench full of August thunderstorm water is nobody’s friend, so late fall through spring is the easier window on an acreage lot.
What does not change is the service behind it. The same 24-hour phone line that handles an air conditioner at midnight handles a geothermal system, and a 3 a.m. call on one is billed at the 3 p.m. rate. Once the loop is in the ground, the thing that needs attention is a heat pump in a closet and a flow center on the wall, which a technician can reach any day of the year. Nothing is outside being rained on, flooded by the Suwannee or clipped by a mower.
Owners who go this route tend to tell us about the quiet first. The second thing they mention is the summer bill.
Loop fields, credits and acreage: what landowners ask
Does the quote cover the trenching and the drilling, or only the equipment?
The written estimate covers the loop field, the drilling or trenching, the heat pump, the indoor connections and the duct changes the house needs, as one number. Ask which loop contractors Cook’s works with in this part of the state and how that portion is scheduled. [[CONFIRM WITH JERRY]]
The air handler is from 2009. Does it go too?
On a geothermal job the heat pump and the air handler are usually one packaged indoor unit, so the old air handler comes out regardless. If you have a split geothermal configuration the question is real, and the answer depends on the coil match; we settle it at the estimate.
Is the financing the same program you use on a regular heat pump?
Monthly payment plans at Cook’s cover new high-efficiency equipment, and a ground-source system qualifies. Terms are set when the quote is written; we never publish a lender, rate or term because they change.
Whose geothermal heat pump do you install?
Cook’s is a Lennox dealer for conventional equipment. Ask which manufacturer’s ground-source units Cook’s installs on a geothermal job; we will name it on the estimate. [[CONFIRM WITH JERRY]]
Can I still claim a federal credit on a ground loop?
No. Nothing installed after 2025 qualifies for the federal residential geothermal credit. Current utility and manufacturer incentives are the ones to ask about, and we will tell you honestly if there are none that apply.
