Why closing doesn't work here
Closing a pool means winterizing the plumbing, dropping the water, and covering it for months. That model exists where water freezes solid for a full season. Central Texas gets short freezes between stretches of sixty and seventy degree afternoons.
A covered, unfiltered pool in that climate turns into a stagnant, algae-heavy mess that costs far more to bring back in March than it ever saved over the winter. Meanwhile the equipment still has to be freeze-protected anyway, so the savings mostly disappear.
Run time comes down, but it doesn't stop
As water temperature drops, so does the demand on your water. Chlorine burns off far more slowly, algae growth nearly stalls, and the pool simply doesn't need as many turnovers a day as it did in August.
That means your pump schedule should be shortened for the season rather than left where it was all summer. We look at water and air temperature together and set run time to what the pool actually needs — no more, no less. Nobody should be paying to run a pump longer than the water requires.
The exception is a freeze. When temperatures head below freezing, run time goes back up, and during a hard freeze the pump should run continuously. Moving water is what keeps pipes from bursting.
Cold water changes the chemistry, not just the schedule
Temperature is one of the inputs to LSI, and cold water pushes the index negative. A pool sitting at a textbook pH in January can still be aggressive enough to quietly etch plaster and erode grout over a few winters.
That's why winter visits aren't just skimming. Balance still gets checked and corrected with digital readings, because winter is when surface damage happens without anyone noticing.
Service rhythm through the cool months
Weekly service continues year-round. What changes is the mix of work: less chlorine, more debris handling early in the season, more attention to run time, freeze readiness, and balance.
Fall and winter are also the easiest months to catch up on the jobs that are miserable in July — filter cleans, salt cell cleans, cleaner rebuilds, and any wet-side repair that means shutting the system down for an afternoon.
