Boiler Repair Dover, NH

When your boiler breaks down in the middle of a New Hampshire winter, you need reliable service fast. At Paul the Plumber, we specialize in comprehensive boiler repair services throughout Dover and the surrounding areas. Our family owned and operated business has been keeping homes warm and comfortable for 22 years, and we understand the unique heating challenges that Dover residents face during those long, cold months.

Boiler systems are complex heating units that require expert knowledge to diagnose and repair properly. Our licensed technicians undergo extensive training to work on all types of boiler systems, from traditional cast iron models to modern high-efficiency condensing units. We maintain our BBB accredited A+ rating by delivering consistent, quality service and treating customers like family throughout every repair process.

Common Boiler Problems We Repair

Boilers can experience various issues that affect their performance and efficiency. One of the most frequent problems we encounter involves water leaks, which can stem from corroded pipes, faulty pressure relief valves, or damaged pump seals. These leaks not only waste water but can also cause significant property damage if left unaddressed. Our technicians use advanced diagnostic equipment to pinpoint the exact source of leaks and provide lasting repairs backed by our 2 year parts and labor warranty.

Strange noises coming from your boiler often indicate serious internal problems that require immediate attention. Banging, whistling, or gurgling sounds typically result from air trapped in the system, mineral buildup on heat exchangers, or failing components like circulation pumps. We’ve earned thousands of verified 5-star reviews across multiple review platforms by quickly identifying these issues and implementing effective solutions that restore quiet, efficient operation to heating systems throughout Dover.

Our Comprehensive Boiler Repair Process

When you call Paul the Plumber for boiler repair, we begin with a thorough system inspection. Our background checked technicians examine every component, from the burner assembly and heat exchanger to the expansion tank and zone valves. We use combustion analyzers to check efficiency levels and ensure your boiler operates within manufacturer specifications. This detailed approach helps us identify not just the immediate problem but also potential issues that could cause future breakdowns.

We believe in up front pricing, which means you’ll know exactly what repairs will cost before we begin any work. Our technicians explain each necessary repair in clear terms, helping you understand what’s wrong and why specific fixes are needed. Whether your boiler requires a simple thermocouple replacement or more extensive heat exchanger repairs, we provide honest recommendations based on what’s best for your home and budget. For our club members, we extend our warranty coverage to 3 years on both parts and labor, providing even greater peace of mind.

Signs Your Boiler Needs Professional Repair

Recognizing early warning signs of boiler problems can prevent costly emergency repairs and system failures. If you notice your energy bills increasing without explanation, this often indicates your boiler is working harder than necessary due to internal issues like scale buildup or worn components. Uneven heating throughout your home, where some rooms stay cold while others overheat, typically points to circulation problems or faulty zone controls that require professional attention.

Water temperature fluctuations and pressure changes also signal the need for expert boiler repair. When your boiler struggles to maintain consistent hot water temperatures or the pressure gauge shows readings outside the normal 12-15 PSI range, internal components may be failing. Our reliable technicians work with integrity to diagnose these issues accurately and recommend appropriate repairs that restore proper system function.

Boiler Repair vs. Replacement Considerations

Determining whether to repair or replace your boiler requires careful evaluation of several factors. Age plays a crucial role, as boilers typically last 15-20 years with proper maintenance. If your unit approaches this age range and requires frequent repairs, replacement might be more cost-effective long-term. However, newer boilers experiencing isolated issues often benefit from targeted repairs that can extend their service life significantly.

We help Dover homeowners make informed decisions by analyzing repair costs against potential energy savings from newer, high-efficiency models. Modern condensing boilers can achieve efficiency ratings above 95%, compared to older units operating at 70-80% efficiency. Our experienced team calculates potential energy savings and discusses financing options, ensuring you understand all available choices. We’re happy to help you weigh these factors and determine the most practical solution for your specific situation.

Emergency Boiler Repair Services

Boiler failures don’t follow convenient schedules, which is why we offer emergency repair services throughout Dover and neighboring communities. Winter temperatures in New Hampshire can drop well below freezing, making a functioning boiler essential for your family’s safety and comfort. Our service with a smile approach extends to emergency calls, where we prioritize rapid response times while maintaining the same high standards of workmanship.

During emergency repairs, we focus first on restoring heat to your home, then address underlying issues causing the breakdown. Common emergency scenarios include complete system failures, gas leaks, or major water leaks that threaten property damage. Our fully stocked service vehicles carry extensive parts inventories, enabling us to complete most emergency repairs in a single visit.

Preventive Maintenance Benefits

Regular boiler maintenance significantly reduces the likelihood of unexpected breakdowns and extends equipment lifespan. Our maintenance services include

  • Comprehensive cleaning of burner assemblies and heat exchangers to maintain peak efficiency
  • Thorough inspection of all safety controls and automatic shut-off mechanisms
  • Professional testing of water quality and treatment to prevent corrosion and scale buildup

We care about helping Dover residents avoid costly repairs through proactive maintenance. During annual tune-ups, our technicians often identify minor issues before they develop into major problems. This preventive approach has helped us maintain our reputation for reliability while saving customers thousands of dollars in avoided emergency repairs. Our maintenance programs include priority scheduling and discounted repair rates, providing additional value beyond the immediate benefits of regular service.

DJ from PTP was incredibly helpful and knowledgeable. My shower was not draining and it became a bigger project than I thought it would and they came out quickly and were able to fix my problem. Then when my water heater had a slow leak they came back out quickly to attend to it and fix my problem. I really appreciate their hard work. Thank you so much!! Would definitely recommend them.

First time customer, and am very pleased with the whole experience. The highlight was definitely with the technicians assigned to the job and their work – Tyree and Corey were clean, polite, well-informed, and very helpful with some of the questions I had along the way. Their work appears to be top-notch, and they made sure no mess was left behind. Will definitely be calling and requesting these two again on any future needs.

K. Bernardo

We’re first time home owners and needed help with some plumbing and adding a filter system. They were able to get a technician scheduled to our house within a day or so of me contacting them. Mike was super helpful and was able to complete all the jobs in a timely manner, and also cleaned up the areas he was working in. Overall a great experience and would definitely use them for future jobs.

V. Vincze

We had an issue with our water…too hard, calcium deposits, and very little pressure in our master bathroom shower only. The techs (Mike E. & Tyler S.) arrived right on time. They were friendly and very personable. After installing our whole house filtration system and successfully finding the issue with our master bathroom, they left the work areas in pristine condition. They were meticulous in their work, and I highly recommend them for any plumbing needs!

John was wonderful. He found the problem right away and fixed it. He checked other outlets just to make sure I would be safe. He explained different programs the company offers also. I’m very happy.

D. Weaver

What a fantastic business. Helped us work with our water district in resolving meter replacement issues. They also fixed a pipe leak that had developed over time. Caleb was wonderful and answered our questions as well as working with the water district engineer on the meter issues. So easy to work with.

M. Richdale

Thanks to Mike Vallee from Paul the Plumber for responding to this new customer’s call so quickly. He was courteous, thorough, explained the repair he was doing and left the work area spotless. I highly recommend Paul the Plumber (and Mike!) to anyone looking for a reliable plumbing company.

W. Chepren

I made an appointment on line the morning of July 31 and two trucks showed up at 1:00 pm right on time that same afternoon. Both guys were friendly and very knowledgeable. They quickly found the source of the wet patch on my ceiling which wasn’t the plumbing but a problem with the shower curtain. This is the second time I have called Paul. Both times I got outstanding service and will always call on Paul the Plumber for any plumbing problems in the future. Very reasonable cost for the visit.

Nick Boudreux

Had a well pump that was shorting out and pretty much had no water. Adrian from this company not only got out next day but was great to work with. He was very friendly and knowledgeable I would definitely recommend this company to anyone that needs work done! Thanks again guys!

D. Marchand

I cannot say enough about this company!!! Their only concern is that you are up and running again with no worries. I’ve had Kyle the plumber, and Josh their electrician out here and both are polite, well trained and you can tell they truly care about getting you back in service. Great service, well trained caring staff! I will never go anywhere else!

T. Minasian

These are the after photos of the Rinnai tankless water heater installation and vent to the outside. It was important to me that the crew was able to use the existing vent hole to the outside to run both the intake vent pipe and the outside vent pipe. It made the job very clean and did not change the appearance of the outside wall. A shout out to Mike E, Caleb, Josh & Corey

D. Lefort

Arrived as scheduled to fix a leak from the shower valve. Tried to fix old 30 or 40 year old unit but had to replace with a new one. Quality work, parts and cleaned up when they were done. Would definitely use again.
