Water Heater Repair in Bolingbrook & the Chicago Suburbs
Searching for water heater repair near me because a cold shower caught you off guard? Few household problems announce themselves as unpleasantly. Aerotech Solution provides water heater repair service for both tank and tankless systems, diagnosing the actual failure point rather than defaulting to full replacement whenever a repair will do.
Water heaters run quietly in the background for years, which is exactly why people are often caught off guard when something finally goes wrong. Electric tank models, gas tank models, and tankless systems each fail differently — from a tripped high-limit switch to a fault code tied to venting or flow sensors — and our technicians are equipped to diagnose all three.

Signs You Need Professional Water Heater Repair
Not every issue means your appliance is done for, but catching these warning signs early usually means a simpler, less expensive repair.
No hot water at all
On electric models, this usually means a failed heating element or tripped high-limit switch. On gas models, a pilot light that won't stay lit or a faulty thermocouple is the common cause.
Water temperature fluctuates unpredictably
Often a failing thermostat, or on tankless units, a flow sensor that isn't correctly modulating burner output.
Rumbling or popping noises during heating
This is a classic sign of sediment buildup at the bottom of the tank, which insulates the heating element and forces it to work harder.
Water appears discolored or rusty
Frequently linked to anode rod depletion or sediment buildup inside the tank, both addressed through flushing and maintenance if caught early.
Visible leaking around the base of the tank
A failing tank generally can't be repaired and needs replacement, while a leaking valve or fitting is often a simple, affordable fix — a technician can tell the difference quickly.
Common Issues
- No hot water
- Leaking tank
- Strange noises
- Water too hot/cold
- Discolored water

Common Water Heater Problems We Fix
Here's a closer look at the specific issues our technicians diagnose and repair most often for this appliance.
No hot water or water not heating
On electric tanks, a failed heating element or tripped high-limit safety switch is the usual cause. On gas tanks, a pilot light that won't stay lit or a faulty thermocouple is common.
Water heater leaking
A leak from the bottom of the tank generally can't be repaired and needs replacement. A leak from the top — often the pressure relief valve or a supply connection — is frequently a simple, affordable fix.
Water not getting hot enough or taking too long to heat
Usually a failing thermostat or a heating element that's no longer reaching full output, though sediment buildup insulating the element can produce the same symptom.
Water heater making noise
Rumbling or popping during heating is a classic sign of sediment buildup at the bottom of the tank, insulating the heating element and forcing it to work harder.
Discolored or rusty water
Frequently a sign of anode rod depletion or sediment buildup, both addressed through flushing and maintenance rather than full replacement if caught in time.
Pilot light won't stay lit
Usually a faulty thermocouple or a draft affecting the pilot assembly, rather than an issue with the gas supply itself.
Electric water heater tripping the breaker
Often points to a failed heating element or element wiring drawing excessive current, rather than an issue with the breaker itself.
Inconsistent hot water temperature
Usually a failing thermostat on tank models, or on tankless units, a flow sensor issue that isn't correctly modulating the burner.
Gas and Electric Water Heater Repair
Gas water heater repair typically centers on the pilot light, thermocouple, gas valve, and burner assembly — issues that require careful, safety-conscious diagnosis rather than guesswork. Electric water heater repair instead focuses on the heating elements, thermostats, and high-limit safety switches. Our technicians are equipped to diagnose both, so you're not searching separately for a gas specialist versus an electric water heater repair service.
Tankless Water Heater Repair & Service
Tankless water heater repair and service covers a different set of components than tank models — flow sensors, ignition systems, venting, and the electronic control board that manages them. A tankless unit losing temperature mid-use, displaying an error code, or not producing hot water at all can usually be traced to one of these systems once we test them directly rather than replacing parts on a guess.
Emergency Water Heater Repair
A water heater failure rarely happens at a convenient time, which is why emergency water heater repair is part of our regular service — particularly for a leaking tank or a complete loss of hot water that can't wait for a routine appointment.
Water Heater Maintenance Services
Beyond repairs, we provide water heater maintenance to help avoid failures before they start — tank flushing to clear sediment buildup, and for tankless systems, periodic descaling to maintain flow rate and heating efficiency, particularly in areas with harder water.
Commercial Water Heater Repair
Our primary focus is residential water heater repair, though we're also able to assist with light commercial water heater repair for smaller multi-family properties and on-site systems. If you're dealing with a larger commercial installation, let us know your setup when you reach out and we can advise whether it's something we're equipped to handle.
Brands We Repair
Our technicians work across every brand listed in Supported Brands above. Here's our experience with a few of the ones we service most often.
A. O. Smith
A. O. Smith tank water heaters are common in the area, and most repairs involve heating element or thermostat replacement.
Bradford White
Bradford White units are known for durability, with most service calls related to sediment buildup or thermocouple issues.
Rheem
We service both Rheem tank and tankless water heaters, including their digital control and flow sensor systems.
Rinnai
Rinnai's tankless systems require specific diagnostic steps for ignition and venting fault codes, which our technicians are trained on.
Bosch
Bosch tankless water heaters are compact, efficient units that need precise flow sensor and burner modulation diagnostics.
American Standard
American Standard water heaters are dependable tank units, typically needing element or valve-related repairs.
Water Heater Installation Services
Alongside repairs, we also handle water heater installation and replacement for both tank and tankless systems — whether you're replacing a failing unit or upgrading to a different type or capacity.
Installation scope depends on your existing gas or electric connection, venting, and plumbing configuration, and whether you're switching between tank and tankless. We'll review these details with you before scheduling; work outside our scope, such as new gas line runs or electrical panel upgrades, would need to be coordinated with the appropriately licensed trade.
When an Appliance Technician or Plumber May Be Needed
Water heater technicians diagnose and repair controls, heating elements, ignition systems, thermostats, and tankless electronics — the majority of water heater problems. Licensed plumbing or gas work may be needed separately for supply line and venting modifications, gas line work requiring a permit, or plumbing issues beyond the water heater itself. If you're not sure which applies, describe the issue when you reach out and we can point you in the right direction.
Repair vs. Replacement: Which Makes Sense?
Tank water heaters typically last 8–12 years, while tankless units can last 15–20 years with proper maintenance. Heating element, thermostat, and valve repairs are almost always worth it, while a leaking tank is the clearest signal that replacement — not repair — is the right move.
What to consider
- Heating element, thermostat, and thermocouple repairs are affordable and worth doing at nearly any point in the unit's life.
- A leaking tank (versus a leaking valve or fitting) virtually always calls for replacement rather than repair.
- Sediment buildup caught early can often be resolved with a professional flush rather than part replacement.
- A tankless unit throwing a fault code is usually a sensor or ignition issue worth repairing rather than a sign the whole system has failed.
Preventive Maintenance Tips
- Flush the tank annually to remove sediment buildup before it insulates the heating element and reduces efficiency.
- Test the pressure relief valve yearly to confirm it's functioning as a critical safety feature.
- Check the anode rod every 2–3 years and replace it if heavily corroded, since it protects the tank itself from corrosion.
- Set the thermostat to 120°F for a balance of safety, efficiency, and comfort.
- For tankless units, schedule an annual descaling service, particularly in areas with harder water, to maintain flow rate and efficiency.
- If you smell gas near your water heater, don't operate any electrical switches or create a flame — leave the area and contact your gas utility or emergency services before doing anything else.
- If water is leaking near electrical connections, stop using the unit and avoid the area until a technician can assess it safely.

Frequently Asked Questions
Is it worth repairing a water heater?
For heating element, thermostat, thermocouple, and valve repairs, generally yes — these are affordable relative to a new unit and fully resolve the issue. A leaking tank is the clearest sign replacement is the better path. Request a diagnosis and we'll give you an honest read on your specific unit.
Do you repair gas, electric, and tankless water heaters?
Yes, our technicians are equipped to diagnose and repair gas, electric, and tankless water heaters.
Why is my water heater not producing hot water?
On electric tanks, a failed heating element or tripped high-limit switch is the usual cause. On gas tanks, a pilot light that won't stay lit or a faulty thermocouple is common. Tankless units often show a specific fault code.
Can a leaking water heater be repaired?
It depends on the source. A leak from the tank body generally can't be repaired and needs replacement. A leak from a valve, fitting, or connection at the top of the unit is often a simple, affordable fix.
Do you provide emergency water heater repair?
Yes, a leaking tank or a complete loss of hot water is treated as a priority rather than a routine appointment.
Do you repair commercial water heaters?
Our primary focus is residential water heater repair, though we're able to assist with light commercial systems for smaller multi-family properties. Let us know your specific setup when you reach out.
How often does a tankless water heater need maintenance?
We generally recommend annual descaling, more often in areas with hard water, to maintain flow rate and heating efficiency.
Do I need a plumber or a water heater repair technician?
A water heater technician handles controls, heating elements, ignition systems, thermostats, and tankless electronics — the majority of problems. Licensed plumbing or gas work may be needed for supply line changes, permitted gas line work, or plumbing issues beyond the unit itself.
How much does water heater repair cost?
Heating element and thermostat repairs are generally affordable; a leaking tank typically requires replacement, which costs more but resolves the issue completely. We provide a fixed quote after diagnosis.
When should a water heater be replaced?
A leaking tank, a unit repeatedly needing repairs, or one nearing the end of its typical 8–12 year (tank) or 15–20 year (tankless) lifespan are the clearest signs replacement makes more sense than another repair.
What water heater brands do you service?
We service A. O. Smith, Bradford White, Rheem, Rinnai, Bosch, and American Standard, among others.
How quickly can I schedule service?
Scheduling is quick and straightforward — book online or contact us and we'll arrange for a technician to assess your water heater.
