Heat Pump Services in Bon Secour.

What heat pump services looks like in this climate.

Run the numbers for this specific coordinate and the heat pump conversation in Bon Secour looks different from the one the industry is having nationally. The 2023 ERA5 reanalysis for the village gives 3,058.9 cooling degree days and 1,001.0 heating degree days. Divide one by the other and you get 3.06 — for every unit of heating work a heat pump does here across a year, it does three units of cooling work. That is the widest split of any mainland community on this site. North Baldwin runs far closer to even; even Magnolia Springs, eight miles up the road, comes in nearer 2.85. The Gulf-front cells do run wider still — Fort Morgan reaches 4.68 — but those are barrier-island and peninsula markets, and the equipment decisions there follow different logic.

Why that matters practically: almost all heat pump marketing is written for markets where the ratio runs the other way. Cold-climate performance ratings, low-ambient capacity retention, sophisticated defrost strategy, backup heat sizing — those are the specifications manufacturers compete on, and they describe capability that a Bon Secour system will exercise on maybe a dozen nights a year. Average January lows here sit around 50.9°F. The equipment is not going to spend its life fighting for capacity at 5 degrees, because 5 degrees does not happen.

What the equipment IS going to spend its life doing is running in cooling mode, often at part load, pulling water out of very humid air, for most of the calendar. So the specifications worth paying for here are cooling-side efficiency and — more than anything else — how well the system modulates down and dehumidifies when it is not at full load. A homeowner in this village who spends the premium on cold-climate heating capability rather than on part-load cooling behavior has bought the wrong upgrade, and nobody selling it to them is likely to say so.

Every Bon Secour neighborhood, every zip.

The one appointment we would push hardest for on a Bon Secour heat pump is the fall visit, and it is the one people most often skip precisely because winter here is so mild. The value is not the heating tune-up in any conventional sense — it is forcing the system to run in heating mode under supervision while the weather is still pleasant. We command a reversing-valve cycle, verify each auxiliary heat stage actually energizes and draws the current it should, and confirm the defrost board responds. Every one of those is a component that will otherwise go untested until the night it is needed.

We work the whole 36511 out of the Daphne shop, which is a run of a little under fifty minutes down US-98 and out through Foley. Heat pump work splits into the scheduled kind — the fall check, a diagnostic on a system that is not swapping modes correctly, a replacement consultation — and the unscheduled kind, which in this community means either a summer cooling failure or one of those few genuinely cold nights. Scheduled work we route with other jobs south of the bay. For the 24/7 line it is (251) 300-9817, and we are licensed in Alabama as AL#23194.

The nights that test a Bon Secour heat pump, and why they cluster.

• Jan 2024 — Hard-freeze week: This is the defining event for heat pump owners in a climate like this one. Several consecutive sub-freezing nights in a place that averages around 1,001 heating degree days a year meant thousands of systems across Baldwin County were asked to run in heating mode, hard, for the first time in months — simultaneously. Stuck reversing valves, dead auxiliary heat strips, and failed defrost boards all surfaced inside the same forty-eight hours. The failures were not caused by the cold; they were revealed by it, which is a meaningful distinction because it means they were all findable in advance.
• Jan 2025 — Gulf Coast snow event: The ERA5 record at this coordinate shows roughly 9.7 cm of snowfall on 21 January 2025, followed by a low of 13.3°F on the 22nd. Put that against an average January low near 50.9°F and it is close to a 38-degree departure — the most extreme cold this village has seen in the modern record. For heat pumps it was a defrost test above all: sustained near- and sub-freezing conditions with high moisture is precisely the regime where the defrost cycle has to work, and precisely the regime equipment here almost never encounters. A system whose defrost function had quietly failed would ice up progressively and shed heating capacity over exactly those days. It also pushed auxiliary heat strips into sustained operation rather than the brief assists they normally see, which is where undersized or partially failed strips gave themselves away.
• Sep 2020 — Hurricane Sally: The heat pump angle on Sally is the outdoor unit. A heat pump's outdoor coil does double duty — it rejects heat in summer and absorbs it in winter — so corrosion or fin damage there degrades both modes rather than one. Surge water pushed up the river and bay reached equipment that never saw damaging wind, and salt in an outdoor cabinet is a slow problem that shows up seasons later as reduced capacity before it shows up as a failure.
