If your home stays warm with the help of a boiler, you must know how to maintain it to keep the equipment in good condition.

While boilers are highly efficient and durable systems, they aren’t immune to problems over time. Understanding the basics of boiler maintenance and repair can help you recognize when it’s time to call in a professional.

Here’s everything you need to know about boilers and the repair services that keep them running.

What Is a Boiler and How Does It Work?

A boiler is a heating system that warms your home by heating water to produce steam or hot water. This heated water is then circulated through radiators, baseboards, or radiant floor systems to provide warmth. Boilers are made up of multiple components, including a burner, heat exchanger, and various controls and safety mechanisms.

While boilers come in different types – such as gas, oil, or electric – they all share the same function: delivering consistent heat.

Common Residential Boiler Problems

Boilers are built to last, with many systems offering a lifespan of 10-15 years (and up to 20 years for high-efficiency models). However, like any mechanical system, boilers can experience issues that require repair.

Here are some common boiler problems to watch out for:

• Water Leaks. Leaks may be caused by high water pressure, loose connections,  or a damaged part.
• Unusual Noises. Sounds like gurgling, whistling, or banging can indicate limescale buildup, air in the system, or low water pressure.
• Lack of Heat or Hot Water. If your boiler isn’t producing hot water or steam, the problem could be a faulty thermostat, low pressure, or a damaged diaphragm.
• Pressure Fluctuations. Extreme pressure changes can lead to inefficiencies and, in severe cases, pose safety risks.

When Should You Call for Boiler Repairs?

Recognizing the warning signs of boiler trouble is the first step in avoiding costly damage. You should contact a professional technician if:

• Your boiler frequently cycles on and off.
• Your energy bills suddenly increase without explanation.
• You notice leaks, unusual noises, or a lack of heat or hot water.

What Happens During a Boiler Repair?

Boiler repairs typically begin with a detailed inspection to identify the root of the problem. Experienced technicians will accurately diagnose the issue, recommend the best course of action, and perform any repairs necessary.

Why Is It Important to Get Repairs Promptly?

Boiler issues should never be ignored, especially during the harsh Massachusetts winters. A malfunctioning boiler can leave your home dangerously cold and cause additional damage if left unchecked.

Prompt repairs help:

• Prevent further wear and tear
• Maintain consistent heating performance
• Avoid more costly repairs or replacements down the line
