The short version
- Most Austin water heater repairs are done in a single visit.
- A tank that leaks from the shell gets replaced, not repaired. We will say so.
- Our hard water is why Austin heaters fail early. Sediment is the usual culprit.
- You get a firm price before any work starts, not an hourly guess.
- No hot water at all is an emergency to us. Call and we will move things around.
What your water heater is doing right now
You are probably reading this in a cold shower, or standing over a puddle in the garage. Here is what those signs usually mean.
No hot water at all. On a gas unit the pilot or the thermocouple is the common cause. On an electric unit it is usually a failed heating element or a tripped high limit switch. Both are repairs, not replacements.
Hot water that runs out fast. The tank is likely full of sediment. Austin water is hard, and the minerals settle to the bottom and take up the room your hot water used to occupy.
Rusty or smelly water. The anode rod has given up. That rod is a sacrificial part. It corrodes so the tank does not, and when it is gone the tank starts to go.
Popping or rumbling. Water is boiling underneath a sediment layer. It is loud, and it is cooking the bottom of your tank from the inside.
Water on the floor. This is the one that decides things. Read the next section.
Why Austin heaters fail early
Central Texas sits on limestone. The water that reaches your house carries a lot of dissolved calcium and magnesium, and a water heater is where that mineral drops out of the water and stays.
A tank rated for twelve years can start failing at seven here. That is not a defect. It is what hard water does to a tank nobody flushed.
It also explains the pattern we see all summer. The heater works fine, then the first cool week arrives, the unit has to work harder, and the weak part finally quits.
Houses on well water east of town scale up faster still. If your neighbors have replaced heaters at eight or nine years, yours is on the same clock, and a softener is the fix that actually changes the outcome.
Repair or replace? How we decide
We would rather fix your heater than sell you a new one. There are three cases where that stops being true.
- The tank itself is leaking. A tank cannot be patched. If water is weeping from the shell rather than a fitting, it gets replaced.
- The unit is past twelve years and the repair is major. Putting a costly part into an old tank buys you a year, and you pay the labor twice.
- It has failed twice in one season. The next call is coming. We will tell you that plainly instead of collecting another service fee.
Anything else is a repair. Thermocouples, elements, thermostats, valves, and flushes are all routine work.
What a visit actually looks like
- You call and we ask four questions. Gas or electric, how old, what it is doing, and whether there is water on the floor. That tells us what to bring.
- We give you an arrival window and we keep it. If we are running late you get a call, not silence.
- We test before we quote. No guessing at the part from the driveway.
- You get a firm price. You approve it before a wrench comes out.
- We fix it and we clean up. The old part goes with us unless you want to see it.
What we carry on the van for this job
- Thermocouples and gas control valves
- Heating elements and thermostats
- Temperature and pressure relief valves
- Anode rods, standard and flexible
- Drain valves and dielectric unions
- Expansion tanks
Most repairs finish on the first visit because the part is already on the truck.
What it costs to wait
A slow leak is the expensive one. A heater that drips for a month does not flood the house. It soaks the subfloor, the baseboard, and whatever is stacked next to it in the garage.
The heater is the cheap part of that repair. The drywall and the flooring are not.
If you see water, shut off the supply valve on top of the unit and call. That one step has saved our customers more money than anything else on this page.
Questions we get asked
How long does a water heater repair take?
Most take under two hours from the time we arrive. A thermocouple or an element swap is faster than that. A full flush on a badly scaled tank takes longer, because we let it drain properly instead of rushing it.
Can you come out today?
Usually yes if you call in the morning. No hot water at all moves to the front of the list, especially for a house with small children or an older adult in it. Call and ask. We would rather tell you no than leave you waiting.
How do I know if my tank is leaking or if it is just condensation?
Dry the area completely and put down a sheet of paper. Check it in an hour. Condensation comes back slowly and evenly across the floor. A leak makes a wet track from one spot. If the paper is soaked near the base of the tank, shut off the water and call us.
Is it worth flushing an older water heater?
If it has never been flushed and it is over eight years old, sometimes it is not. Breaking loose a thick sediment bed can open a corroded spot underneath. We will look at the drain water first and tell you honestly whether to flush it or plan a replacement.
Do you charge to come out?
There is a service call fee and we tell you the number on the phone before we schedule. If you have us do the repair, that fee comes off the total.
Still no hot water?
Tell us what it is doing and we will tell you what it needs. If it is something you can fix yourself in five minutes, we will say that too.
