How To Tell if You Need Boiler Repair
Commercial boilers and water heaters often give early warning signs before a complete breakdown. Recognizing these red flags can help you avoid downtime and schedule repairs before the problem worsens.
Strange Noises (Banging, Whistling, Gurgling)
Unusual sounds often indicate limescale buildup, trapped air, or failing components inside your boiler or water heater. Left untreated, these issues reduce efficiency and can lead to major mechanical failure.
Uneven Heating or No Hot Water
If your facility is experiencing inconsistent hot water or none at all, it’s a clear sign your system requires professional attention. This may stem from circulation issues, thermostat problems, or sediment clogging the tank.
Leaks, Low Pressure, or Frequent Resets
Water pooling near the unit, drops in system pressure, or a constant need to reset your boiler are all indicators of deeper issues. These could point to failing seals, internal leaks, or safety controls malfunctioning—problems that should be addressed immediately by a licensed water heater technician.
Rising Utility Bills
A sudden spike in your utility costs often means your commercial water heater is working harder than it should. Sediment buildup, aging burners, or failing insulation can all lead to reduced efficiency and higher operating costs. Repair or replacement is often the most cost-effective long-term solution.
Slow Recovery or Heating Times
If it takes significantly longer than usual for your system to reheat water, this is often a sign of worn-out heating elements or failing components. Slow recovery water heater performance disrupts operations in high-demand facilities like restaurants, healthcare, and manufacturing.
Visible Rust or Corrosion
Rust around valves, connections, or the tank itself is a red flag that your system is deteriorating. Corrosion not only reduces efficiency but also increases the risk of leaks and complete system failure. At this stage, most facilities benefit from commercial water heater replacement rather than ongoing repairs.

Water Heater Services Frequently Asked Questions
Is it worth it to repair a water heater?
Yes — if your unit is relatively new and the issue is minor, water heater repair can restore performance at a fraction of the cost of replacement. However, if the system is old, inefficient, or has recurring breakdowns, replacement is usually more cost-effective in the long run.
What is usually the most common water heater problem?
The most common issues are sediment buildup, faulty thermostats, and worn-out heating elements. These problems can cause inconsistent hot water and slow recovery times. Regular water heater maintenance helps prevent them.
What is the life expectancy of a water heater?
On average, commercial water heaters last 8–12 years, depending on usage, maintenance, and water quality. Tankless water heater installations often last longer—up to 20 years with proper care.
Do you call a plumber to fix a water heater?
Yes. A licensed plumber is typically the best professional to handle water heater repair near me searches, since they’re trained to handle both plumbing and safety code requirements. Andrews’ commercial team specializes in large-scale systems.
Who is the best person to replace a water heater?
A licensed water heater technician is always the right choice. At Andrew’s, our specialists are trained in commercial water heater replacement, ensuring efficient installations that meet Arizona codes.
Will a home warranty replace an old water heater?
Most warranties cover repairs for breakdowns, but they often don’t cover full replacement of outdated or inefficient units. For businesses, it’s better to rely on a trusted commercial contractor like Andrew’s for reliable guidance.
When to replace vs repair a water heater?
If your system is leaking, corroded, or over 10 years old, it’s usually more cost-effective to replace it. If problems are minor—such as a valve or heating element issue—repairs can extend the system’s life.
What type of water damage is not covered by insurance?
Insurance typically doesn’t cover gradual damage, such as long-term leaks or corrosion. That’s why preventative water heater maintenance is so important for businesses—it reduces risk, prevents downtime, and limits liability.
