Heater Replacement in Concord, NH

When winter temperatures in Concord, NH plunge well below freezing, your heating system is not a luxury but a lifeline. At Paul the Plumber, we understand how critical a reliable heater is for your family’s comfort and safety. As a family owned and operated company that has been in business for 22 years, we have helped thousands of homeowners navigate the process of heater replacement with confidence. Whether your existing system has reached the end of its lifespan or you are dealing with escalating repair costs that no longer make financial sense, our team is here to guide you through every step of the replacement process with upfront pricing and service with a smile.

When Is It Time to Replace Your Heater?

Most residential heating systems have an expected lifespan of 15 to 20 years, depending on the type of equipment, usage patterns, and how consistently the unit has been maintained. According to the U.S. Department of Energy, heating accounts for roughly 29 percent of a typical home’s energy bill, making it the single largest energy expense for most households. When your system begins to age, it loses efficiency gradually, meaning you pay more each month for the same level of warmth. If your furnace or boiler is approaching or has exceeded the 15-year mark, it is worth scheduling an evaluation to determine whether replacement is the smarter investment compared to ongoing repairs.

Beyond age, there are several telltale signs that your heater may need to be replaced. Frequent breakdowns, uneven heating throughout your home, unusual noises during operation, and a noticeable increase in your energy bills all point toward a system that is struggling to perform. Yellow or flickering pilot lights on gas furnaces can indicate incomplete combustion, which poses a potential carbon monoxide risk. If you have needed multiple repairs in the past two heating seasons, the cumulative cost of those fixes often exceeds the value of the aging equipment. We always provide honest assessments because we believe in treating our customers like family and working with integrity.

Our Heater Replacement Process

Replacing a heater is a significant home improvement decision, and we take a methodical approach to ensure the outcome meets your expectations. The process begins with a thorough in-home assessment where one of our licensed and background-checked technicians evaluates your current system, inspects your ductwork or piping, measures the square footage of your living space, and considers factors such as insulation quality, window efficiency, and ceiling height. This load calculation is essential for determining the correct size of your new heating unit. An oversized system cycles on and off too frequently, wasting energy and creating temperature fluctuations. An undersized system runs constantly without adequately heating your home.

Once we have completed the assessment, we present you with replacement options tailored to your home and budget. We walk you through the differences between equipment types, efficiency ratings, and features so you can make an informed decision. Our upfront pricing model means you know exactly what the investment will be before any work begins. There are no hidden fees or surprise charges. After you approve the plan, our technicians handle the full installation, including removal of the old equipment, proper connection of the new unit, testing for safe operation, and verification that the system meets all local building codes in Concord, NH.

Types of Heating Systems We Install

Every home is different, and the ideal replacement heater depends on your existing infrastructure, fuel availability, and personal preferences. We install a wide range of heating systems to serve the diverse needs of homeowners in the Concord area and beyond.

  • Gas furnaces remain the most popular heating option in New England due to their powerful heat output and relatively low operating costs when connected to natural gas lines
  • Oil furnaces and boilers are common in homes without natural gas access, and modern oil-fired systems offer significantly improved efficiency compared to older models
  • Heat pumps provide both heating and cooling capabilities, making them a versatile choice that can reduce the need for separate HVAC equipment
  • Boiler systems distribute heat through radiant floor heating or baseboard radiators, delivering consistent and comfortable warmth throughout every room
  • Ductless mini-split systems offer zone-controlled heating for homes without existing ductwork or for additions and converted spaces

Each of these systems comes with distinct advantages depending on your situation. For instance, modern gas furnaces with AFUE ratings of 95 percent or higher convert nearly all the fuel they consume into usable heat, compared to older units that may operate at only 60 to 70 percent efficiency. Heat pumps have also seen dramatic improvements, with cold-climate models now capable of efficient operation even when outdoor temperatures drop below zero. Our technicians stay current on the latest equipment advancements so we can offer expert guidance as part of our trusted plumbing, HVAC, and electrical services.

Energy Efficiency and Long-Term Savings

Upgrading to a high-efficiency heater is one of the most impactful ways to reduce your home’s energy consumption. The Environmental Protection Agency estimates that replacing an old furnace with an ENERGY STAR certified model can save homeowners an average of 15 percent on heating costs annually. Over the lifespan of the equipment, those savings can amount to thousands of dollars. Additionally, many utility companies in New Hampshire offer rebates and incentive programs for homeowners who install energy-efficient heating equipment, further offsetting the upfront investment.

Beyond monthly utility savings, a new heater replacement improves indoor air quality by eliminating the dust, rust, and debris that older systems can circulate throughout your home. Modern systems also operate more quietly and deliver more consistent temperatures from room to room. These quality-of-life improvements make the investment worthwhile on multiple levels, not just financially but in everyday comfort.

Preparing for Your Heater Replacement

Before your installation day, there are a few things you can do to ensure a smooth process:

  1. Clear the area around your existing heating equipment, providing our technicians with ample workspace to safely remove the old unit and install the new one
  2. Ensure accessible pathways from your front door to the mechanical room so equipment can be transported without obstacles
  3. Discuss any concerns or preferences with your technician during the initial assessment, including thermostat placement, zoning options, or noise considerations

Taking these simple steps helps us work efficiently and keeps the installation timeline on track. Most heater replacements in residential settings can be completed in a single day, minimizing the disruption to your household during the colder months. Once the installation is complete, our technician walks you through the operation of your new system, explains the warranty details, and answers any questions you may have.

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.

Michele

I’ve used Paul the Plumber twice now for electrical issues and they have been wonderful each time. They are fast, polite, knowledgeable, and very fairly priced. They explain everything well and answer my questions thoroughly and I feel safer now knowing what was causing my electrical issues and having it fixed! I will be using Paul the Plumber for all my household needs going forward

H. MacPherson

I would recommend Paul the Plumber 100%. They offered same/next day service. They were friendly, professional and quick – from the office staff to the technicians. Overall an amazing experience from start to finish.

J. Wojo

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.

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!

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.

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!

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.

K. MacCallum

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.

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

S. DesMarais

Josh was amazing. He was able to install my ring doorbells with no issues. He also did a great check of my homes smoke detectors and a few electrical plugs. He was thorough, Knowledgeable, and easy to work with. I would definitely use them again.

J. Shea

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.

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.
