Water Heater Repair in Chicago

SAVA provides water heater repair and replacement in Chicago and suburbs for gas, electric, and tankless units across all major brands. Same-day service is available when slots are open. Our $79 diagnostic fee is credited toward the repair — you get a full estimate and a repair-vs.-replace comparison before we start any work. Most water heater repairs are completed in a single visit.

The average tank water heater lasts 8–12 years. A repair typically costs $150–$350, compared to $800–$2,500 for a full replacement. For units under 8 years old, repair almost always makes more financial sense.

Common water heater problems we fix

  • No hot water at all. On gas units this is usually a failed thermocouple or a pilot light that won't hold. On electric units one or both heating elements have burned out. On tankless units, we read the error code and trace it to the specific component — flow sensor, igniter, or control board.
  • Water not hot enough. The thermostat is most often set too low or has failed. On electric units, a partially failed lower heating element produces warm but not hot water. We test both and replace whichever component is underperforming.
  • Water heater leaking. A leak at the top usually means a failing inlet or outlet valve. A leak from the bottom often means the tank itself is corroding and replacement is the only fix. Leaks from the pressure relief valve indicate dangerous over-pressure — address immediately.
  • Rumbling, popping, or banging sounds. Sediment buildup on the tank floor causes this. The sediment superheats and pops as the burner cycles. We flush the tank; if sediment buildup is severe, we give you an honest assessment of whether the tank has remaining life.
  • Pilot light won't stay lit. Almost always a worn thermocouple that can no longer hold the gas valve open. This is a quick, inexpensive repair — we carry thermocouples for all major brands and can usually fix it same day.
  • Discolored or rusty hot water. Rust-colored water from hot taps only points to the anode rod inside the tank being fully depleted. Replacing the anode rod stops the corrosion and extends tank life. If the tank itself is corroding, replacement is the better call.

Frequently asked questions

How much does water heater repair cost in Chicago?

We charge a $79 diagnostic fee, which is credited toward the repair if you proceed. Common repairs — thermocouple, heating element, pressure relief valve — typically run $150–$350. Full replacement cost varies by unit size and type; we give you a straight comparison before you decide.

Why is my water heater not producing hot water?

For gas units, the most likely cause is a failed thermocouple or a pilot light that won't stay lit. For electric units, one or both heating elements have burned out. For tankless units, the problem is often a flow sensor, igniter failure, or a specific error code that points to a component.

My water heater is making rumbling or popping sounds — is that bad?

Yes. That sound is sediment that has settled on the bottom of the tank and is being heated. Over time it causes the tank to overheat, reduces efficiency, and accelerates tank failure. Flushing the tank can resolve it if caught early enough.

Should I repair or replace my water heater?

If the unit is under 8 years old, repair is almost always the right call. If it's 10 or more years old and failing, replacement usually makes more financial sense. We give you a straight side-by-side comparison so you can make an informed decision — no upselling.

Do you install tankless water heaters?

Yes. We repair and install both tank and tankless water heaters including Rheem, AO Smith, Bradford White, Navien, and Rinnai. We also handle the gas or electrical work required for the installation.
