Callahan, Bryceville and Hilliard: what the co-op bill is really saying
West of I-95 the electric bill comes from a co-op, the water comes from the ground and the house is more likely to be manufactured than block. All three change what a high summer bill means.

Four things the bill can mean out here
Callahan sits at the junction of US 1, US 301 and A1A with two CSX lines running through it, a town of about 1,500 that serves a wide rural area. Bryceville is the unincorporated stretch along US 301 to the southwest, and Hilliard is the next town north on US 1. Out here most homes are served by Okefenoke REMC or FPL rather than JEA, water comes from private wells, and a large share of the housing is manufactured homes on acreage with package units. When a homeowner calls about a summer bill that jumped, the cause is almost always one of four things: a package unit losing efficiency with age, ducts under the home leaking into the crawl, a system that’s too big or too small for the home, or a window unit quietly running alongside the central system.
Three kinds of house on three roads
Manufactured homes on acreage. The package unit sits outside on a pad and feeds a trunk duct in the belly of the home. Those ducts tear, sag and pull loose at the boots, and the cooled air goes into the crawlspace. The unit then runs longer, and the bill climbs. Sealing or replacing the belly ducts is often the biggest single saving available.
1960s-80s block and frame houses in Callahan and Hilliard. Older split systems or package units, sometimes with a window unit still in a back bedroom. Attic ducts, thin insulation, equipment on its third round.
Newer houses on the county roads. Conventional split systems from the 2000s and 2010s, approaching the age where coils and compressors start to go, with the usual attic-duct leakage.

Where the kilowatt-hours go
| Driver | How it shows on the bill | What we do |
|---|---|---|
| Aging package unit | Runs longer every year for the same result | Clean, charge, test; replace when the compressor is near the end |
| Belly or attic duct leaks | Long run times, rooms that never cool | Seal or replace the duct system |
| Wrong size equipment | Short cycling, or constant running | Size the replacement from a load calculation |
| Window unit plus central | A second compressor’s worth of draw | Fix the room the window unit is compensating for |
| Well-water effects | Stains and corrosion near the air handler | Inspect condensate handling and any humidifier |
The point where a new package unit pays
A package unit that has reached fifteen to twenty years on a manufactured home is usually cheaper to replace than to keep feeding parts, and a new high-efficiency unit paired with sealed ducts can cut the summer bill noticeably. JEA’s rebate doesn’t apply to co-op or FPL customers out here; we’ll tell you what, if anything, your utility offers at the time of the estimate. Cook’s offers financing with low monthly payments and free estimates on new systems.
The drive, and why we make it
Western Nassau is about eighty-five miles from our shop at 37 Fairmont Ln in Palm Coast, roughly an hour and forty minutes by I-95 and I-10 or up US 301. There are far fewer HVAC companies working these roads than in the city, and the ones that do often won’t come after five. We run Callahan, Bryceville and Hilliard on scheduled route days, dispatch any hour for an emergency, and never add an after-hours charge. Family-owned, Lennox dealer, every major brand and every package unit repaired.
Western Nassau questions
Why is my Okefenoke bill so much higher than my brother's JEA bill in town for a smaller house?
Co-op rates differ from the municipal utility’s, and a manufactured home with a package unit and belly-board ducts loses a lot of cooled air before it reaches the rooms. The rate is the co-op’s business; the duct losses and the equipment efficiency are ours, and they’re usually where the savings are.
Can the well water hurt the air conditioner?
Not the refrigerant side. It affects anything the water touches: condensate pumps in some setups, humidifiers, and the condition of plumbing near the air handler. Iron and sulfur staining around the unit tells us to look closer.
Do you work on package units for manufactured homes?
Yes, repair and replacement. Package units are the standard equipment on manufactured homes across western Nassau, and we carry the parts for them. When one is replaced we size it from the home and the duct system, not the old nameplate.
How far is Bryceville from you, honestly?
About eighty-five miles and an hour and forty minutes, I-95 to I-10 to US 301. Callahan and Hilliard are similar. We run western Nassau on scheduled days and come regardless for a no-cool or no-heat.
