Tioga is twenty. Oakmont is five. The ground west of I-75 didn't ask either one's age.
One of these communities is finishing its first round of system replacements. The other is finishing its first builder warranties. Both sit on the part of Alachua County where the clay thins out.
Two communities, one generation apart
The Town of Tioga started going up off Newberry Road around the turn of the century: a 500-acre traditional-neighborhood development with small lots, front porches, alleys and a mixed-use town center that now has its own restaurants and offices. Its first homes are about twenty years old, and it’s still adding phases. Oakmont, on SW 24th Avenue near I-75, broke ground in the mid-2010s: 556 acres, six builders, larger upscale homes, a clubhouse, and most of its houses under ten years old.
They get called the same thing, “new Gainesville west of the interstate,” and they need almost opposite things from us. Tioga is a retrofit-and-replace neighborhood now. Oakmont is a first-summer-check neighborhood. The thing they share is the ground.
Replacement in Tioga versus the first check in Oakmont
Tioga’s first-generation systems were installed in the early 2000s, which makes them builder-grade 10 to 13 SEER heat pumps on R-410A, now at or past their normal life. The replacement job in Tioga is a known quantity: same pad, same line set if it passes a pressure test, a right-sized modern heat pump, and a close look at the ducts before the equipment goes in. The small-lot layout means the condenser is often in a side yard a few feet from the neighbor’s, so noise ratings matter more here than in a subdivision with wide setbacks.
Oakmont’s systems are mostly under warranty and mostly fine. What Oakmont needs is the shakedown that construction schedules skip: charge verified against the manufacturer’s chart rather than left at the factory setting, the condensate float switch tested, the thermostat moved if it’s on a sun-struck wall, the duct trunk inspected where it turns, and the pad checked for level. We’ve found brand-new systems in Oakmont low on charge from day one and nobody noticed because the house was still cooling.
Ductwork realities in a tight house
Both communities were built to codes that make the house itself far tighter than a 1970s ranch. That’s good for the bill and hard on the air. A tight house with a leaky duct system pulls attic air into the living space every time the blower runs; a tight house with a well-sealed duct system can run humid in the shoulder months because the system barely cycles. In Oakmont we see the second problem, and the answer is a dehumidification strategy, not a bigger unit. In Tioga we see the first, because twenty-year-old flex duct has pulled loose at the boots, and the answer is sealing before replacement.
Both neighborhoods have attic air handlers with long horizontal duct runs to the far bedrooms, and both have two-story floor plans served by one system. Upstairs-is-hot is the most common comfort complaint we get from either address.
Sizing for the thin clay
West of I-75 the clay layer that protects the limestone underneath thins out, which is why Alachua County’s sinkholes cluster here, including the 2023 collapse in Oakmont. For us that’s a pad question. We set condensers on pads that can be re-leveled, we check them for tilt at every visit, and we make sure the line set has slack rather than running taut to a cabinet that could move an inch. A refrigerant line stressed by a tilted pad leaks at the brazed joint, usually a year later, and it’s a leak that didn’t need to happen.
Sizing comes from a load calculation, never from the old unit’s nameplate or the square footage. Tioga’s small lots and porches shade walls that a model would otherwise count as sun-exposed. Oakmont’s larger glass areas and high ceilings pull the other way. Two houses of the same square footage in the two communities can need different equipment, and we calculate it rather than guess.
Utilities and the drive
Tioga and much of Oakmont are served by Gainesville Regional Utilities or Clay Electric depending on the parcel, and the rebate programs differ: GRU leans on paid duct testing and energy surveys, Clay offers a heat pump rebate and an energy survey. Which meter you’re on is the first question on a replacement quote, and whether a given program pays through the installer is a point we’ll confirm for your address. [[CONFIRM WITH JERRY]]

Tioga and Oakmont owners ask
Our Oakmont house is three years old and the upstairs is always warmer. Is that a defect?
Usually it’s a design shortcut rather than a defect: one system, one thermostat downstairs, and a long flex run to the second floor that was never balanced. Dampers, a second return upstairs or a zoning board are the fixes, roughly in order of cost. We’ll check for a crushed or kinked duct first, because in new attics that’s common.
The builder's one-year warranty just ended on our Oakmont system. What should we have looked at?
Refrigerant charge, drain float switch, duct connections at the trunk and the boots, thermostat location and the condenser pad for level. Builder installs are done on a schedule, and those five things are where corners get cut. A single maintenance visit covers all of them.
Our Tioga house still has its original 2004 system. Replace it before it fails?
Not on the calendar alone. Have it serviced, know the refrigerant type and the condition of the compressor, and get a replacement quote in hand so a breakdown in August is a phone call instead of a scramble. A system that’s still efficient and quiet at twenty has earned another season.
After the 2023 sinkhole, is there anything HVAC-specific we should do?
Have the pad checked for level and the line set checked for stress at every maintenance visit, and consider a flexible line-set connection if a pad has moved before. Sinkholes are a geology problem, not an HVAC one, but a shifted pad is how geology reaches the refrigerant lines.
