The bill jumped, the habits didn't: three things to check on the JEA or Clay Electric app before you call us
A high summer bill in Clay County has two possible authors: the utility and the house. Ten minutes in the utility's app usually tells you which, and it costs nothing to look before we drive an hour to find out.
Before we roll a truck: three things to check on the JEA or Clay Electric app
Orange Park is 58 miles from our shop. We will happily make the drive, but a bill complaint deserves ten minutes of homework first, because some of the answers are already in your phone.
First, the rate and the days. Open the bill in the app and compare kilowatt-hours, not dollars, with last year’s matching month. Then check the billing period; a 33-day cycle against a 29-day one explains a lot of jumps on its own. Both JEA, inside the Town of Orange Park, and Clay Electric, across Lakeside, Middleburg and most of unincorporated Clay, show this on the statement.
Second, the daily chart. Both apps show usage by day. If every day is uniformly higher than last summer, something is running more all the time. If a handful of days spike, match them against the calendar: a heat wave, houseguests, the week the pool pump timer got reset.
Third, the overnight floor. Look at how low usage drops between midnight and 5 a.m. A house with everyone asleep and the air conditioner cycling normally has a clear floor. A floor that is suddenly higher than last year is a thing that runs all night: a stuck heat strip, a well pump, an old refrigerator in the garage, a system that never shuts off.
The empty-house problem: what runs while Clay County commutes
Eight in ten Clay County workers commute out of the county, mostly up US 17 or across the river, and the average drive is the longest in Florida. Houses here are empty ten hours a day. The thermostat setback that was supposed to save money during those hours is where a lot of surprises hide. A programmable thermostat that lost its schedule in a lightning outage runs the house at 72 all day for nobody. A smart thermostat set to recover to 72 by 5:30 p.m. runs flat out through the hottest hour. A system that cannot keep up at 78 by afternoon runs continuously and never reaches setpoint, which is invisible unless you look at the runtime.
What we find at the house, most to least often
When the app says the house is the author, we meter the system. Ranked roughly by how often each proves to be the cause across the Orange Park area:
- Electric heat strips energized in summer. A stuck sequencer or a miswired thermostat lets the strips run alongside the cooling. The house feels the same; the bill does not. More common on the 2000s Oakleaf and Fleming Island systems than anywhere else.
- A dirty or failing condenser. A coil packed with pine straw and cottonwood fluff, or a weak capacitor, makes the compressor draw far more current for the same cooling.
- Duct leaks into a hot attic. Conditioned air blown into the attic and 130-degree air pulled back in. The 1960s-70s block ranches and the 2000s two-stories both do this.
- Low refrigerant. The system runs long and cools little.
- A short-cycling, oversized unit that costs a start every six minutes.
- Not the air conditioner at all. Pool pumps, well pumps, water heaters with a failed element, a second refrigerator. We say so and do not charge for a repair we did not make.
When the math says replace instead of repair
A twenty-year-old first-generation system with a stuck strip and a dirty coil gets fixed, and the bill drops. The same system with low refrigerant on a leaking coil and a compressor drawing high amps gets a repair price and a replacement price side by side. The replacement side includes what a correctly sized, current-efficiency heat pump does to a four-month cooling season’s bills, a monthly payment plan, and the Clay Electric or JEA rebate the address qualifies for. Washington’s 25C credit lapsed with the 2025 tax year, so it is not in the math. Enrollment details for any program that pays through the contractor are something we confirm [[CONFIRM WITH JERRY]].
A bill-watching habit for next summer
Check the overnight floor in the app once a month. Note the kilowatt-hours for July and August each year on the inside of the thermostat door. Schedule the spring maintenance in March so the coil is clean before the May heat and the strips are confirmed off. A bill that jumps with no change in habits almost always announced itself on the daily chart weeks before the paper arrived.
High-bill questions from JEA and Clay Electric customers
What does the air conditioner normally account for on a Clay County summer bill?
Roughly half, sometimes more in a large or leaky house during the hottest weeks. If the bill jumped by a third and the daily usage chart shows the increase spread across every day rather than clustered, start with the air conditioner.
We're on Clay Electric and the bill is high in winter too. Different problem?
Often the same component. Electric heat strips that run when they should not, because of a stuck relay or a heat pump that is not keeping up, inflate winter bills the same way a stuck strip inflates summer ones. The Clay Electric app will show the spikes on the cold mornings.
Does JEA or Clay Electric offer a home energy check?
Clay Electric requires an energy survey as part of its conservation loan program, and both utilities publish usage tools in their apps. Neither replaces a technician with a clamp meter at the air handler, but both are free and worth doing first.
Could the well pump at our Middleburg place be the jump instead of the air conditioner?
Yes, if a leak or a stuck check valve keeps it cycling. A well pump running all night shows up in the app as usage that does not drop after midnight. It is one of the non-HVAC causes we rule out by asking about the house.
App checked, and it still points at the air conditioner?
Call. We'll put a meter on the system and give you the cause and the cost before anything is fixed.
