Boiler Repair & Maintenance Services in Baltimore

Trusted Hydronic Heating Professionals Serving Baltimore & Harford Counties

Unlike forced-air furnaces that heat your home through air ducts, boiler systems heat water to heat your home through radiators, baseboard units, or under-floor pipes (radiant heating). It takes specialized expertise to properly install, service, and maintain boiler systems.

 At Mike's Plumbing & Heating Service, Inc., we are boiler heating specialists. We maintain and repair all makes and models of home boiler heating systems in Baltimore and the surrounding areas, including Essex, Dundalk, Towson, and cities throughout neighboring Harford County.

Schedule your boiler repair or maintenance service by calling (410) 541-1811.

Why Regular Boiler Maintenance is Essential

Boilers are so dependable that it’s easy to forget they require routine maintenance – but they do. As part of your boiler service appointment, we will inspect the tank as well as other vital components, including the heating element and the piping throughout your home. We will address any issues we find to help prevent future breakdowns and ensure reliable heating in your Baltimore-area home. Annual preventive boiler maintenance helps ensure optimum performance, fewer repairs, longer equipment life, and lower utility costs.

Emergency Boiler Repair Services in Baltimore

Your boiler has a way of letting you know it needs our attention. If your boiler is exhibiting any of these warning signs, contact our experts ASAP:

• Gurgling and whistling sounds – This could be from air in the system, not enough water, or lack of maintenance.
• Burn marks – If your boiler appears to have been burnt, the cause could be a blocked vent or chimney.
• Water beneath your boiler – Water on the floor could indicate a faulty safety system, faulty fresh-water feed, or thermostat setting that’s too high.
• Rust on top of the machine – Two common causes are a build-up of carbon monoxide or not enough clean air in the system.
• Dirt and particles on top of the machine – A lack of combustion air is often the cause.

Regardless of your issue, you can count on our Baltimore boiler repair technicians to provide efficient and comprehensive services. We have been helping Baltimore homes and businesses heat their properties at optimum levels since 1984.

Boiler Service FAQ

How Frequently Should You Schedule Boiler Servicing?

Most homeowners should schedule boiler servicing once a year. Annual maintenance helps ensure safe operation, improves energy efficiency, and reduces the risk of unexpected breakdowns. The exact frequency can vary based on the boiler’s age, type, usage, and manufacturer guidelines.

If you notice unusual noises, inconsistent heating, higher energy bills, or system shutdowns, it’s best to have your boiler inspected sooner rather than waiting for your annual service.

What Are Signs My Boiler Needs to Be Repaired?

Common signs your boiler may need repair include:

• Inconsistent or insufficient heat
• Unusual noises such as banging, whistling, or rumbling
• Frequent cycling on and off
• Rising heating bills with no change in usage
• Water leaks or corrosion around the unit

You may also notice uneven heating throughout your home or longer warm-up times. If your boiler emits strange odors or shuts down unexpectedly, professional boiler repair should be scheduled right away to prevent further damage or safety concerns.

Why Is My Boiler Making a Kettling Noise?

Kettling is a rumbling or boiling sound caused by mineral buildup or sludge inside the boiler or heat exchanger. This buildup restricts water flow, causing overheating and steam bubbles that create the noise.

Other causes can include low water pressure or a failing pump. While kettling may seem minor at first, it can reduce efficiency, increase energy costs, and damage internal components if left untreated. Professional boiler cleaning, flushing, or repairs can usually resolve the issue and restore quiet operation.

Is a Noisy Boiler Dangerous?

Some boiler noises are harmless, but loud banging, hissing, or kettling sounds should never be ignored. These noises may indicate pressure issues, overheating, mineral buildup, or mechanical problems that could lead to system failure or safety risks.

If your boiler is making persistent or worsening noises, it’s best to have a licensed technician inspect the system to ensure safe and reliable operation.

Can a Boiler Cause Carbon Monoxide Issues?

Yes, a malfunctioning boiler can produce carbon monoxide if it’s not burning fuel properly or if venting is blocked. Carbon monoxide is a colorless, odorless gas that can be extremely dangerous.

Signs of a potential issue include headaches, dizziness, soot buildup near the boiler, or frequent pilot light problems. Annual boiler maintenance and working carbon monoxide detectors in your home are essential for protecting your family’s safety.

When Should I Replace My Boiler Instead of Repairing It?

Boiler replacement may be the better option if your system is:

• Over 15–20 years old
• Requiring frequent or costly repairs
• Heating your home unevenly
• No longer energy efficient

Upgrading to a high-efficiency boiler can improve comfort, lower energy bills, and reduce the likelihood of breakdowns. A professional assessment can help determine whether repair or replacement is the most cost-effective solution for your home.

Why Upgrade to a High-Efficiency Boiler?

Older boilers can waste energy and struggle to keep up with heating demands. High-efficiency boilers use advanced technology to deliver consistent heat while consuming less fuel.

Benefits of high-efficiency boilers include:

• Lower energy consumption
• Reduced carbon footprint
• Decreased heating costs
• Improved indoor comfort
• Longer system lifespan

If your current boiler is outdated or inefficient, upgrading can provide long-term savings and improved performance.
