The one licensed edge
Nobody licenses pool cleaning in Texas, but electricians are licensed through TDLR, and the equipment pad is electrical work: pumps, heaters, salt cells, lights, bonding. When a company quotes equipment installs or repairs, ask who does the electrical side and whether they are licensed for it. Water and electricity share a small space at a pool, and this is exactly the corner not to let anyone cut.
Chemistry is the product
The visible work is skimming; the real product is water chemistry that never lets algae start, which in this heat is a weekly discipline. Ask how their techs are trained, whether readings get logged where you can see them, and what happens when a reading is off. A company that talks in specifics about balance and this climate is selling service; one that talks about how shiny your pool will look is selling skimming.
Consistency you can verify
Ask whether the same tech runs your route each week and how you know a visit happened, because pools reward routine and suffer from turnover. Good outfits leave a log or a report each visit, readings included. Then ask for two customers on your side of town who have been with them over a year; a service business that cannot produce two happy year-long customers nearby is new, stretched, or churning.

What should I check no matter what?
Four things, every time: proof of liability insurance sent directly from their insurer, not a photocopy; how long they have worked this area under this name; local references you can actually call; and a written scope before any money moves. Anyone offended by those four is answering your question.
