Water Heater Repair and Diagnostics

A malfunctioning water heater can disrupt your entire household. Our team is equipped to diagnose and fix all major issues with gas, electric, and heat pump water heaters.


Signs Your Water Heater Needs Professional Attention:


  • Lack of Hot Water: The most obvious sign, often caused by a faulty heating element, pilot light issue, or tripped breaker.
  • Strange Noises: Popping, rumbling, or banging sounds often indicate sediment buildup at the bottom of the tank, which forces the unit to work harder.
  • Leaks: Water pooling around the base of the unit can signal a faulty valve, a loose connection, or, critically, a corroded tank that requires immediate replacement.
  • Discolored Water: Rusty or brown-tinted water typically means the tank is corroding internally or the anode rod needs replacing.
  • Foul Odors: A "rotten egg" smell suggests a bacterial issue in the tank that needs professional flushing and sanitization.


If you experience any of these symptoms, call our Southborough service team right away to prevent further damage or system failure.

Water Heater Installation & Replacement Options

Upgrading your water heater can significantly reduce your energy consumption and provide a more consistent supply of hot water. We specialize in helping you choose the right system for your family’s needs and budget.


1. Traditional Tank Water Heaters

These are the most common and generally have a lower upfront cost. Newer tank models are more efficient than their predecessors, and they are easier to replace when necessary. We ensure proper sizing to avoid running out of hot water during peak usage times.


2. Tankless (On-Demand) Water Heaters

Tankless water heaters only heat water when you need it, eliminating the standby energy losses associated with keeping a large tank of water constantly hot.


  • Feature Tankless (On-Demand) Traditional Tank
  • Energy Efficiency Up to 34% more efficient; significant long-term savings. Lower efficiency due to continuous reheating.
  • Hot Water Supply Endless supply of hot water. Limited by tank size; can run out.
  • Lifespan Typically 20+ years. Typically 10–15 years.
  • Space Compact, wall-mounted unit; saves floor space. Large storage tank requires more room.


We provide professional installation for both gas and electric tankless systems, ensuring proper venting and utility line requirements are met.

Water Heater Maintenance

To maximize efficiency and extend the lifespan of your unit, regular maintenance is essential:

Tank Flushing

We perform annual flushing to remove sediment buildup, which is the leading cause of poor efficiency and premature tank failure.

Anode Rod Inspection

 Checking the anode rod protects the tank from corrosion and is vital for maximizing system life.

Pressure Valve Check

Testing the Temperature and Pressure Relief (T&P) valve ensures safety and proper operation.

Heat Pump Water Heater Services

Heat pump (hybrid) water heaters are one of the most energy-efficient ways to heat water, using heat from the surrounding air instead of generating it directly. This makes them 2–3 times more efficient than traditional electric water heaters, helping homeowners reduce energy bills while enjoying consistent hot water.

Benefits of Heat Pump Water Heaters

  • Lower Energy Costs – High efficiency means long-term savings on monthly utilities.
  • Eco-Friendly Operation – Uses less electricity and produces fewer emissions.
  • Built-In Dehumidification – Helps reduce moisture in basements or utility rooms.
  • Long Lifespan – Durable components provide reliable performance for many years.
  • Rebate Eligible – Many models qualify for state and federal incentives.

Is a Heat Pump Water Heater Right for Your Home?

These systems perform best in areas with 40–90°F temperatures and enough space for proper airflow. They may have a higher upfront cost, but their long-term savings and efficiency make them an excellent upgrade for most homes.

Why Choose Metro West Mini Splits?

Our team specializes in heat-pump-based systems, ensuring proper sizing, placement, and installation for maximum performance. We provide clear estimates, help you take advantage of available rebates, and offer ongoing maintenance and support to keep your system running efficiently.

  • How can I tell if I need to replace my water heater instead of repairing it?

    If your unit is old, leaking, producing rusty water, or requiring repeated repairs, replacement may be the safest and most cost-effective option. Our team will evaluate your system and help you decide based on condition, age, and performance.
