Expert Boiler Repair Services

When your boiler breaks down, you need help fast. A malfunctioning boiler can lead to a cold home, no hot water, and even potential safety hazards like water leaks or gas issues. Common signs of trouble include strange noises like banging or whistling, water pooling around the unit, a pilot light that won’t stay lit, or a complete lack of heat. Ignoring these signs can lead to more extensive and costly damage.

At John Nugent & Sons, our skilled technicians are equipped to diagnose and repair all types of boiler problems. We arrive with fully stocked trucks, allowing us to resolve most issues in a single visit. We are committed to restoring your home’s heat and your peace of mind as quickly as possible, ensuring your system operates safely and efficiently once again.

Protect Your Investment

Comprehensive Boiler Maintenance

Annual maintenance is the key to keeping your boiler running efficiently and reliably, season after season. Just like a car, your boiler needs regular tune-ups to perform at its best. Neglecting maintenance can lead to decreased efficiency, higher energy bills, unexpected breakdowns, and a shorter system lifespan. Proactive care helps catch small issues before they escalate into major, costly repairs.

A professional tune-up ensures all components are clean, safe, and working correctly. During a maintenance visit, our technicians will thoroughly inspect, clean, and test your boiler. This preventative service not only enhances performance but also ensures the system is operating safely, giving you peace of mind throughout the winter.

Maximize Efficiency & Lifespan

What Our Maintenance Service Includes

Our comprehensive boiler maintenance service is designed to cover all critical aspects of your system. We leave no stone unturned in our efforts to ensure your boiler is ready for the heating season. Key steps include inspecting for leaks, testing pressure and safety controls, cleaning and checking burners and heat exchangers, and lubricating moving parts to reduce wear and tear.

By investing in one of our annual service plans, you can enjoy priority scheduling and potential discounts on repairs. Regular maintenance from John Nugent & Sons protects your warranty, lowers the risk of a mid-winter breakdown, and keeps your system running as efficiently as possible, saving you money on utility costs.

Have Questions?

Boiler Frequently Asked Questions

We understand you may have questions about your home’s boiler system. To help, we’ve compiled answers to some of the most common questions we receive from homeowners in our community.

How often should I have my boiler serviced?

We recommend professional maintenance for your boiler once a year, ideally in the fall before the heating season begins. This ensures it operates safely and efficiently when you need it most.

What are the signs that my boiler needs repair?

Common signs include strange noises (banging, gurgling, or whistling), leaks or puddles around the unit, a yellow pilot light (it should be blue), inconsistent heating, or a sudden increase in your energy bills.

How long does a boiler typically last?

With proper annual maintenance, a modern boiler can last 15 to 20 years. If your boiler is approaching this age and requires frequent repairs, it may be more cost-effective to replace it.

Is it better to repair or replace my old boiler?

This depends on several factors, including the age of the boiler, the cost and frequency of repairs, and its energy efficiency. Our technicians can provide an honest assessment to help you make an informed decision that best suits your home and budget.

What are the benefits of a high-efficiency boiler?

A new high-efficiency boiler can significantly reduce your energy consumption, leading to lower utility bills. They are also more reliable, operate more quietly, and are better for the environment than older, less efficient models.

Still Have Questions About Your Boiler?

Your home’s heating system is complex, and it’s natural to have questions. If you didn’t find the answer you were looking for, or if you have a specific concern about your boiler, please don’t hesitate to reach out.
