The bill jumped and nothing changed: three Gainesville statements, read line by line
The same habits, the same thermostat, a bill a third higher. Before anyone sells you a system, read the statement the way we do.
Three bills, three different stories
A high summer bill in Alachua County arrives on three kinds of paper, and the same jump means something different on each.
The GRU all-electric house. A heat pump home in Haile Plantation or Westchester gets one combined statement with electric, water and wastewater. Cooling is the largest electric line by far from May to September, so a usage jump with the same weather is almost always the system.
The GRU gas house. A Duckpond or older Northwest Gainesville home with a gas furnace and a straight air conditioner. In summer the furnace burner is off and the electric line is still the cooling story, but in a winter jump the gas therms and the electric kilowatt-hours have to be read together: a furnace that stopped lighting and left the house on an electric space heater shows up as gas down, electric up.
The Clay Electric or Duke house. Rural Alachua County toward Archer and Hawthorne: electric only, often a well pump and a package unit on the pad. The AC competes with the pump for blame, and the statement’s month-by-month history is the tool.
In every case the step is the same: find the kilowatt-hours, compare them to the same month a year ago, and check whether the month was actually hotter before blaming anything. A run of 95-degree afternoons raises usage with no fault anywhere. If the weather was ordinary and usage rose by a quarter or more, keep reading.
The equipment faults that write a higher bill
In the order we find them on the Alachua County route:
- Heat strips running in summer. A stuck sequencer, a failed relay or a thermostat miswired on a replacement energizes the air handler’s electric strips while the compressor cools. The house feels fine and the bill nearly doubles. Found with a clamp meter in two minutes.
- A condenser coil packed with canopy debris. Under oak and pine, a coil clogs in a spring. Head pressure climbs, the compressor draws more current for less cooling, and run times stretch.
- Low refrigerant charge. A slow leak on 1990s and 2000s equipment means longer cycles at lower capacity, every hour of every day.
- Duct leakage. Nearly half the city’s homes predate 1980, and original ducts in attics and crawlspaces leak conditioned air out and pull hot air in. The GRU residential duct test puts a number on it.
- Short cycling or a stuck fan relay. Frequent compressor starts draw several times running current; a blower that never stops adds its own line.
- A failing compressor. Drawing high amperage against worn valves, cooling less each year. This is the one that ends in a replacement conversation.
- A window unit or a fan switch left on. In student rentals a bedroom window unit can equal half the central system’s usage; in any house, a fan switch set to on instead of auto adds a steady line and pushes humidity back indoors.
What we measure at the house
A high-bill visit is a measurement visit, not a sales call. We clamp the air handler, the strips, the condenser and the blower and compare current draw to the nameplate. We read refrigerant pressures and the temperature split across the coil. We check the condenser coil and the filter. We look at the thermostat wiring and the sequencer. If the equipment is clean, we pressure-test the ducts or point you to GRU’s test. The result is a short written list: what is drawing more than it should, what it costs to fix, and what the bill should do afterward.
When the bill is the argument for replacing
A compressor drawing well over nameplate on a fifteen-year-old system, or a coil leak on equipment that runs the older refrigerant, puts the repair against a new system’s efficiency on the same sheet. A modern two-stage or variable-speed Lennox heat pump, correctly sized for a shaded Gainesville lot, cuts the summer kilowatt-hour line enough that financing with low monthly payments can come close to washing out against the bill. Clay Electric’s Energy Smart rebate applies to qualifying heat pumps, and we confirm your address’s incentives on the estimate.

High-bill questions from GRU, Clay Electric and Duke customers
My GRU statement has electric, gas, water and wastewater on one page. Which line matters for the AC?
The electric kilowatt-hours. GRU’s combined bill moves with water and gas rates too, so a higher total does not mean the air conditioner changed. Compare this month’s kilowatt-hours to the same month last year; a jump there with the same weather is the signal.
We lost power for two days after Helene. Why was the next bill higher, not lower?
A house that sat at 85 and 80 percent humidity for two days takes many hours of full-output running to recover, and a storm that long often leaves a damaged capacitor or a stuck relay behind that keeps drawing after the lights come back. We check for both on post-storm calls.
Does GRU or Clay Electric offer a home audit that would catch this?
GRU offers energy and water surveys, and Clay Electric’s Energy Smart program includes a free energy survey; both can flag duct leakage and strip heat running out of season. They do not diagnose equipment, which is what our visit adds. Whether Cook’s participates in either utility’s contractor programs is something we confirm for you. [[CONFIRM WITH JERRY]]
