The $499 water heater install does not exist — not in San Marcos, not anywhere. The companies below are listed in part because their quoting culture runs all-in, with the pan, expansion tank, and permit where you can see them.
Local context matters in the selection: Texas State rental density means landlord turn-work, aging duplexes, and systems that get run hard by tenants — alongside regular family neighborhoods that deserve better than rental-grade service.
The mix below is deliberate — established local operators alongside the metro institutions whose scheduling depth carries peak season, all with verifiable San Marcos-area coverage across Blanco Gardens, Willow Creek, Hughson Heights and the surrounding area. The grid sorts them fast; the detail cards route you by situation.
| Company | Focus | Known for | Service area |
|---|---|---|---|
| Woods Comfort Systems | HVAC + plumbing | Three generations, 70+ years in Texas comfort | San Marcos, Dripping Springs & Hill Country |
| Clearwater Plumbing & Water Treatment | Plumbing + water treatment | Hill Country treatment specialist; tests first | Dripping Springs & Hill Country |
| Cold Is On The Right | Plumbing, water heaters & softeners | 5-star reviewed plumbing shop with treatment focus | Austin & west metro |
| Radiant Plumbing & Air Conditioning | Plumbing + HVAC + electrical | Decades-established Austin multi-trade firm | Austin metro & Hill Country |
| Daniel's Plumbing & Air Conditioning | Plumbing + HVAC | Top-listed across suburban Angi/HomeAdvisor rankings | Austin metro & suburbs |
| Proficient Plumbing Solutions | Repairs, water heaters, emergency service | Same-day & emergency availability | Bee Cave, Lakeway & SW Austin |
| Stan's Heating, Air, Plumbing & Electrical | Full-service HVAC + plumbing | 4.7/5 across thousands of reviews (Best Pick Reports) | Greater Austin metro |
Calibrate before anyone visits: the installed-cost guide shows what every code item should run, and the tankless-vs-tank decision deserves ten minutes before a cold shower forces it.

An Austin institution since the 1950s holding a 4.7 rating across several thousand Best Pick Reports reviews — multi-trade licensing, deep scheduling bench, and financing options that smaller shops can't float.
What stands out: Scale with a verified record — thousands of reviews at 4.7 is the hardest signal to fake in this trade.
Best fit: Households wanting institutional accountability and peak-season scheduling depth.
Verifiable San Marcos-area service came first — published coverage or local presence, because drive time shapes everything from trip fees to August availability in Hays County. Then licensing posture (RMP-led Texas plumbing licensing), insured crews, and public review records across Google, Yelp, Angi, and BBB — weighted for volume and consistency over perfection.
Code-complete quoting culture led the cut: all-in numbers with pan, expansion tank, permit, and haul-away itemized. Hard-water fluency (anode strategy, softener conversations) and same-day capability on no-hot-water calls rounded the weighting. Editorial order.
