The Clay Electric or FPL bill jumped and nothing changed in the house: a line-by-line read before anyone blames the heat

Reading the bill before calling anyone

Pull last August’s bill and this one. Ignore the dollar amount for a moment and find the kilowatt-hours used. FPL prints it with a usage history; Clay Electric does too. Then look at the average temperature for the two periods, which both bills often show or which the weather service will tell you. If usage rose about in step with the heat, the air conditioner is probably fine and the summer is just long. If usage rose far more than the weather did, or if the same month last year was much cheaper, something in the house changed, and the air conditioner is the largest suspect because it is the largest load.

Also check the billing days. A 33-day cycle against a 29-day one explains more “jumps” than people expect.

The three usual HVAC causes in Putnam County

Heat strips running in summer. Most heat pumps here have electric resistance strips for freeze nights. When a thermostat wiring fault, a stuck sequencer or a damaged control board energizes those strips while the system is cooling, the air conditioner fights its own heater. The house still cools, so nothing feels wrong, and the bill can double. This is the first thing we check with a clamp meter, and it is far more common than homeowners imagine, especially after a surge.

A system that has quietly lost efficiency. A fifteen- or twenty-year-old unit with a dirty coil, a slow leak or a weakening compressor runs longer every year for the same cooling. There is no single moment of failure. The bill is where the decline shows up, a little more each summer, until a July arrives that costs a third more than the one before.

Ducts cooling the attic or the crawlspace. A split trunk in a 130-degree attic over a Newtown block house, or a belly duct under a manufactured home in East Palatka hanging open to the crawlspace, sends a share of every cooling dollar outside the living space. The system runs more, the house is less comfortable, and the bill rises. A room that never gets cool while the system runs constantly is the sign.

What each one costs to fix, in scale

The strips: usually a small electrical repair, a sequencer, a relay or a thermostat rewire, same visit. The duct: moderate, a day of sealing and reconnecting in the attic or under the home, and it pays back fast. The tired system: this is the repair-or-replace conversation, and when the unit is past fifteen years and the bill has climbed for several summers, replacement is often the cheaper decade. A high-efficiency replacement can qualify for Clay Electric’s Energy Smart rebate at rural addresses, and for FPL’s residential program in Palatka and East Palatka through an enrolled contractor; whether Cook’s is enrolled is a question for Jerry.

Call for a bill-driven checkup

When the bill is not the air conditioner

Before we blame the HVAC, we ask about the other big loads. A water heater with a failed lower element runs its upper one constantly. A pool pump on a broken timer runs 24 hours. A well pump with a failing pressure switch or a leak in the line cycles all night; on a rural Putnam property that is a classic hidden load. A chest freezer in a hot carport works twice as hard in July. And a Georgia-Pacific shift schedule that put someone home during the day changes usage more than any appliance.

If the kilowatt-hours jumped and the air conditioner checks out, we will say so, and we will tell you where to look next instead of selling you a system.

The visit

We arrive from the Palm Coast headquarters with a clamp meter and a set of gauges. We measure current at the strips, the compressor and the blower; check the charge; look at the coils; and walk the ducts. You get a plain statement of what the air conditioner is costing you against what it should, and what the options are. No after-hours charge.
