Most pool companies in Dallas will tell you weekly service is the way to go. That's partly because it's good for their business. But it's also because they've seen what happens when Dallas homeowners try to stretch it to biweekly or monthly.
It doesn't go well.
Pool chemistry in a 95-to-105-degree environment doesn't move slowly. Chlorine burns off faster. Algae grows faster. pH swings harder. A pool that tests perfectly on Monday can be cloudy by Thursday if nobody's watching it.
That's not an exaggeration. In July and August, free chlorine levels can drop from 3 ppm to under 1 ppm in three or four days. Once you dip below 1 ppm, algae has an open invitation. And algae in Dallas summer heat doesn't creep in. It explodes.
Weekly service means someone's testing and adjusting before the chemistry slides far enough to cause a visible problem. Biweekly means you're gambling that nothing goes sideways for 14 days in 100-degree heat. That's a bad bet.
Dallas sits in a wind corridor. Spring brings heavy pollen loads from oak, cedar, and pecan trees. Summer brings dust storms and afternoon thunderstorms that dump leaves, dirt, and debris into your pool in 20 minutes. Fall cottonwood season is its own kind of mess.
Debris isn't just cosmetic. Organic material breaks down in your water and consumes chlorine. A pool full of leaves and pollen needs more chemicals than a clean pool. If that debris sits for two weeks, you're not just dealing with a dirty pool. You're dealing with a chemistry problem that's harder and more expensive to correct.
Pools in heavily treed yards in DFW often need more than standard service. If you've got mature oaks, expect your tech to spend extra time on skimming and vacuum work every single visit.
Your pump, filter, heater, and salt cell don't care about your cleaning schedule. But they do care about water chemistry. A pool running low on chlorine grows algae that clogs your filter. High calcium hardness scales your heat exchanger. Low pH corrodes metal fittings.
Weekly service catches these issues before they cost you money. A tech who's at your pool every week notices when the pump sounds different, when the filter pressure is climbing, when the salt cell isn't producing like it should. A tech who shows up once a month finds problems after they've already done damage.
We've seen pool heaters fail at $2,500 to replace because nobody noticed the calcium buildup for months. That's the kind of thing weekly eyes on your equipment prevents.
People skip weekly service to save money. That makes sense on paper. But here's what typically happens.
You clean the pool yourself for a few months. Then you get busy, or it gets too hot, or you go on vacation. The pool turns green. Now you're paying $400 to $600 for a green pool recovery. Do that twice a year and you've spent more than a full year of weekly service would have cost, and you still did most of the work yourself the rest of the time.
Weekly service at $149 a month is $1,788 a year. Two green pool recoveries plus the chemicals you bought trying to maintain it yourself can easily hit $2,000+. And that doesn't account for your time, which in Dallas summer heat is worth something.
A proper weekly visit in Dallas should take 30 to 45 minutes for a standard residential pool. The tech should skim the surface, vacuum the floor, brush the walls and tile line, empty the pump and skimmer baskets, test the water chemistry (pH, chlorine, alkalinity at minimum), adjust chemicals as needed, and check the equipment.
After each visit, you should get a report. Digital is best. It should show what was done, what the chemistry readings were, and any notes about equipment or water condition. If your pool company isn't sending you something after every visit, they're either not testing or not tracking. Neither is good.
Same tech, same day, every week. That consistency matters because the person cleaning your pool learns your pool. They know which corner collects leaves. They know your filter pressure baseline. They notice when something changes. A rotating crew of different techs every week misses things.
It's rare in Dallas, but there are situations where biweekly holds up. Indoor pools. Pools with solid covers that stay on between uses. Small plunge pools with minimal surface area. Pools that only operate a few months a year.
If your pool is outdoors, uncovered, and you use it regularly from April through October, weekly is the answer. Every pool company in DFW will tell you that, and on this one, they're right.
