Alachua and High Springs on the first 28-degree night
The hot season gets the attention. But the night the thermometer on Main Street in Alachua or by the river in High Springs drops to 28 is when we find out which heat pumps were only ever half working.
The signs, in the order they show up
The freeze window in Alachua County opens in early December and runs to late February, and most winters bring a few nights at or below 28. In Alachua and High Springs, the two cities up US 441 northwest of Gainesville, the first of those nights produces the same calls every year. The signs come in a sequence:
- Early November: the system switches to heat for the first time and there’s a burning-dust smell that lasts an hour. Normal. If it lasts a day, it isn’t.
- The first frost: the outdoor unit steams and makes a whooshing sound every half hour or so. That’s defrost, and it’s fine. If it ices over and never clears, the defrost board or sensor has failed.
- The first night in the twenties: the house loses ground overnight, the thermostat shows “aux” or “emergency heat” and nothing changes, or the breaker for the air handler trips. That’s the strip heat, and it has been dead since the last cold winter.
- The morning after: the GRU, Alachua city or Clay bill for that week, when it arrives, is startling. Strip heat is the most expensive way to heat a house, and a system that leans on it because the heat pump side is weak runs it for hours.
What waiting costs
A heat pump that limps through a freeze on strip heat alone is spending several times the electricity it should, and it’s doing it on the coldest nights when the city and co-op grids are already strained. Beyond the bill, a system that’s low on refrigerant in December was low in August too, and a compressor running on a starved charge for a season is how a cheap leak repair becomes a compressor replacement. The one thing not to do is set the thermostat to emergency heat and leave it there through February; that’s the expensive heat, and it tells us nothing.
What the fix involves
A no-heat visit in Alachua or High Springs checks the system in order: outdoor unit first for defrost operation, reversing valve and refrigerant charge; then the air handler for the strip heat elements, their sequencers and the breaker feeding them; then the thermostat’s wiring, because a lot of “aux heat never comes on” calls are a thermostat that was never set up for a heat pump when a previous owner installed it. Most fixes are a sequencer, a defrost board, a sensor or a strip element, and most are finished on the first visit. A reversing valve or a low-charge system with a coil leak on an older unit is the point where we price repair against replacement in writing.
High Springs adds a wrinkle: much of the town sits on Duke Energy Florida, which runs a home energy check and an HVAC replacement rebate in its territory, while the rural parcels around it are Clay Electric. Alachua runs its own municipal electric. Which program applies and any installer-enrollment requirement is confirmed per address. [[CONFIRM WITH JERRY]]
Alachua’s two halves and High Springs’ one
Alachua is a city of about ten thousand with a historic Main Street, 1970s-90s subdivisions to the south and west, and the Progress District biotech campus with newer housing nearby. The older subdivisions are where the strip-heat failures live; the newer ones mostly need their thermostats set up correctly for heat pump operation.
High Springs is the river town at the end of the run: a downtown of antique shops and restaurants, a grid of older frame and block houses, and acreage out toward the Santa Fe River and the springs. Houses here are more often on wells, more often shaded, and more often heated by a mix of a heat pump and a wood stove or space heaters when the pump can’t keep up. Replacing the backup heat with a system that actually works is a common job.
Keeping it from happening again
A fall maintenance visit, scheduled in October or early November before the first freeze, runs the system in heat mode, forces a defrost cycle, confirms the strip heat draws its rated amperage and checks the refrigerant charge. It is the single most useful visit of the year for a heat pump in Alachua or High Springs, and it’s the one most households skip because the house is still comfortable in October. The number for either visit, the planned one or the one at 2 a.m. in January, is 866-266-5709.
Alachua and High Springs callers ask
My heat pump runs all night on a freeze night and the house never gets above 64. Is it broken?
Something in it is. A heat pump alone loses capacity as the outdoor air drops into the twenties, and that’s what the auxiliary strips are for. If the house can’t recover, the strips aren’t engaging, the defrost cycle is stuck, or the system is low on refrigerant and has been all summer without anyone noticing.
Alachua has its own electric company. Does that change what you'd install?
It changes the paperwork more than the equipment. The City of Alachua runs its own electric utility with its own programs, separate from GRU and Clay. A heat pump still makes sense for a climate that’s hot nine months and freezes seventeen nights a year; we’ll check what the city offers on efficiency rebates at quote time.
We're in High Springs on a well. Why does the air handler drain crust up so fast?
The Floridan aquifer here is hard, and the private wells around High Springs deliver it without the softening GRU adds in Gainesville. Condensate itself is pure, but if a humidifier or a mini-split’s drain shares the path, or well water splashes the pan during a flush, it scales. An annual cleaning handles it.
How quickly can you get to Alachua or High Springs for no heat on a freeze night?
Alachua is about two hours and fifteen minutes from our Palm Coast headquarters up US 441; High Springs is a little farther. A no-heat call with an elderly person or an infant in the house is dispatched ahead of routine work, at any hour, with no night surcharge.
