We’re BBB accredited with an A+ rating, and we back all our work with a 2-year parts and labor warranty, with the option to extend to 3 years when you become a club member with us.

Understanding Your Heating Options

The heating landscape has evolved significantly over recent years, with modern systems offering efficiency levels that would have seemed impossible just a decade ago. Furnaces remain the most common heating solution in New Hampshire homes, with gas furnaces achieving efficiency ratings of up to 98% AFUE (Annual Fuel Utilization Efficiency). This means that 98 cents of every dollar spent on fuel directly converts to heat for your home. Oil furnaces, while traditionally popular in New England, typically operate at 85-90% efficiency when properly maintained and can be excellent choices for homes without natural gas access.

Heat pumps have revolutionized home heating in recent years, particularly with advances in cold-climate technology. Modern air-source heat pumps can maintain efficiency even when outdoor temperatures drop below zero, making them increasingly viable for New Hampshire winters. These systems provide both heating and cooling, eliminating the need for separate systems and potentially reducing overall equipment costs. Ground-source or geothermal heat pumps, while requiring higher initial investment, can achieve efficiency ratings of 300-400%, meaning they produce three to four units of heat for every unit of electricity consumed.

Boiler systems continue to serve many Amherst homes effectively, particularly in older properties with existing radiator or baseboard heating infrastructure. Modern condensing boilers can achieve efficiency ratings above 95%, capturing heat from exhaust gases that older models waste. These systems provide consistent, comfortable heat and can also supply domestic hot water, serving dual purposes with a single unit.

The Installation Process: What to Expect

Every successful heater installation begins with a comprehensive home assessment. Our technicians evaluate your home’s size, insulation quality, window efficiency, and existing ductwork or distribution system. We calculate heat load requirements room by room, ensuring your new system neither overshoots nor falls short of your heating needs. Proper sizing prevents short cycling in oversized systems and inadequate heating from undersized units, both of which lead to premature wear and higher operating costs.

During the installation phase, we prioritize minimal disruption to your daily routine while maintaining meticulous attention to detail. For furnace installations, this includes careful removal of old equipment, modifications to existing ductwork if necessary, and precise calibration of new components. We ensure proper venting for combustion gases, install new thermostats with programming capabilities, and verify all safety controls function correctly. Our technicians take time to seal duct connections, reducing air leakage that can account for up to 30% of heating energy loss in typical homes.

Critical Installation Considerations

Ductwork condition significantly impacts heating system performance, yet many homeowners overlook this crucial component. Even the most efficient furnace struggles to deliver comfort if ducts leak conditioned air into unconditioned spaces like attics or crawlspaces. We inspect existing ductwork thoroughly, identifying areas requiring sealing or insulation upgrades. In some cases, duct modifications improve airflow balance, eliminating hot and cold spots that plague many homes.

  • Proper ventilation requirements: Ensuring adequate combustion air supply and exhaust venting protects your family from carbon monoxide risks
  • Electrical upgrades: Some heating systems require dedicated circuits or panel upgrades to handle increased electrical loads
  • Zoning considerations: Installing zone controls allows different areas of your home to maintain different temperatures, improving comfort and reducing energy waste
  • Smart thermostat integration: Modern thermostats learn your schedule and preferences, automatically adjusting temperatures for optimal efficiency

Energy Efficiency and Long-Term Savings

Investing in high-efficiency heating equipment pays dividends through reduced operating costs and enhanced comfort. The Department of Energy estimates that upgrading from a 60% efficient furnace to a 95% efficient model can save up to $375 annually in heating costs for an average home. Over the system’s typical 15-20 year lifespan, these savings often exceed the initial investment difference between standard and high-efficiency models.

Beyond equipment efficiency ratings, proper installation techniques dramatically impact system performance. Studies indicate that incorrect installation can reduce efficiency by up to 30%, negating much of the benefit of high-efficiency equipment. Our commitment to up-front pricing means you’ll know exactly what your installation costs before work begins, allowing you to make informed decisions about efficiency upgrades and optional features. We’re happy to help you navigate available rebates and incentives that can offset installation costs, making high-efficiency systems more accessible.

Maintaining Your Investment

After installation, regular maintenance ensures your heating system continues operating at peak efficiency while extending equipment lifespan. We offer comprehensive maintenance programs that include annual tune-ups, filter replacements, and priority service for unexpected issues. Our technicians document system performance at each visit, identifying potential problems before they escalate into costly repairs. This proactive approach reflects our belief that we’re not just installing equipment—we’re establishing long-term relationships with our customers. We care about your comfort and satisfaction long after the installation truck leaves your driveway. With our reliable service and commitment to working with integrity, you can trust that your new heating system will provide years of dependable comfort for your Amherst home, backed by our service with a smile philosophy that has defined Paul the Plumber for over two decades.

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.

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.

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.

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!

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

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!

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. 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.

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. Baraket

Never used Paul The plumber company before but I’m glad I did. Very courteous, professional and pleasant from the answering service (Diane) to employees (Jeremy). They diagnosed the problem and fixed it in no time. Very happy and satisfied with their service. Definitely will use again. Thank you

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!

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.

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.

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.

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.
