San Antonio-area patterns we see
Climate and housing age in San Antonio tend to drive specific failure patterns. We see the same handful of issues every season.
On bigger jobs we'll bring two techs. On simpler ones, just one — fewer hands, faster billing.
Recent service example
Got a call last month from a downtown San Antonio home — 2020+ build. Symptom: tankless unit producing cold-water sandwich. Cause: calcium scale in the heat exchanger. Descaled the unit and recommended annual maintenance, all done in before lunch, billed flat-rate at $754.
What you're paying for
Water heaters last 8 to 12 years on average — less in hard-water regions, more if the anode rod gets replaced every 4 years. Most calls come at end-of-life when the tank starts leaking from the bottom seam.
When the tank goes, swap it. Repair on a 10-year-old tank that's leaking is throwing money away. We carry standard 40 and 50 gallon gas and electric tanks on our trucks for same-day install. Tankless replacements take 1–2 days because of the gas-line and venting work.
If you have a tankless unit and you're getting cold-water sandwich (hot for 30 seconds, cold for 10, hot again), it's almost always scale buildup in the heat exchanger. Annual descaling fixes it — $225 to $380 — and is required by the manufacturer to keep your warranty valid.
Brand-wise, we install whatever you want. Defaults we keep stocked: Rheem and AO Smith for tank, Rinnai and Navien for tankless. Bradford White on commercial.
