Call Us for a Furnace Installation!

If you’re in Derry then you know our winters can still be freezing even without any snowfall. Keeping toasty on those cold winter nights is easy when you avoid major problems by upgrading your heater. Five perks of a new furnace installation include:

  • Lower energy costs
  • Quieter operation
  • Improved airflow
  • Better air quality
  • Increased indoor comfort

Our technicians can help you choose the perfect heater for your home needs and then install it flawlessly. We provide you with peace of mind on every service and even offer upfront pricing to take the stress out of new installations.

Signs That You Need a New Furnace Installed

While we always opt for repairs first, sometimes a new installation just makes more sense. If you notice any of the following signs, then you should consider installing a new furnace soon.

  • 15-20 years old
  • Lack of efficiency
  • Visible cracks in the unit itself
  • Rising utility bills
  • Frequent or costly repairs

A Look at the Furnace Installation Process

The first step in any furnace installation is making sure you select the right unit to install. Your HVAC technician can help you determine what size furnace you should install. The size of the furnace you’ll need depends on two factors: what the winter is like where you live, and the size of your home.

Living in New Hampshire, we get cold winters, so we need larger furnaces than people who live in Southern California, for example. Depending on the size of your home in Derry, you may require a furnace that is anywhere from 1.5 tons (for a 700 to 1,100 sq ft home) to 5 tons (for a larger 2,700 to 3,300 sq ft home).

Once you have selected a furnace, your HVAC technician will inspect your air distribution system. If your ductwork is in good shape, the furnace installation can begin and should be done in no time. If your ductwork needs repairs though, that will need to be done before the new furnace can be installed.

Once your new furnace has been set in place, your HVAC technician will begin to connect it. The connection process includes:

  • Making sure the furnace is properly aligned.
  • Connecting the furnace to the ductwork.
  • Sealing the connections.
  • Connecting the condensate line.
  • Connecting the flue pipe system.
  • Making electrical connections (including connecting your new furnace to your thermostat).
  • Connecting the gas line (if a gas powered furnace) and making sure there are no leaks.

When you call Paul The Plumber for your furnace replacement, we’ll help you determine the right size, make and model to suit your unique needs. Rest easy knowing we have years of experience to provide you with the right recommendation and install your furnace according to code.

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

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!

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. 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.

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.

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

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.

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.

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.

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.

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.

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!

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.

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
