AC Installation in Exeter, NH — Comfort You Can Count On

When summer temperatures climb across southern New Hampshire, having a reliable air conditioning system is not a luxury — it is a necessity. At Paul the Plumber, we provide expert AC installation services to homeowners and businesses throughout Exeter, NH, and the surrounding communities. As a family owned and operated company that has been in business for 22 years, we understand the unique climate challenges that come with New England living. Our commitment to treating every customer like family means we take the time to assess your specific cooling needs, recommend the right equipment, and install it with precision so your home stays comfortable for years to come.

Exeter is a town rich in history and character, with homes ranging from centuries-old colonial structures to modern new construction. Each type of property presents different considerations when it comes to air conditioning installation. Whether you are replacing an aging system or installing central air for the first time, our team of licensed and background checked technicians has the training and experience to handle every scenario. We are BBB accredited with an A+ rating, and we have thousands of verified 5-star reviews across multiple review platforms — a reflection of the quality work and honest service we deliver every single day.

Why Professional AC Installation Matters

According to the U.S. Department of Energy, heating and cooling account for roughly 48 percent of the energy used in a typical American home. An improperly sized or poorly installed air conditioning system can drive those costs even higher while failing to keep your living spaces comfortable. Professional installation ensures that your new system operates at peak efficiency from day one, reducing energy waste and extending the lifespan of your equipment. The average central air conditioning system lasts between 15 and 20 years, but that longevity depends heavily on the quality of the initial installation.

At Paul the Plumber, we begin every AC installation project with a thorough load calculation. This process evaluates the square footage of your home, insulation levels, window placement, ductwork condition, and other factors to determine exactly how much cooling capacity you need. An oversized unit cycles on and off too frequently, leading to humidity problems and premature wear. An undersized unit runs constantly without adequately cooling your home. Getting the sizing right is one of the most critical steps, and it is something we never shortcut. We offer up front pricing, so you always know what to expect before any work begins — no surprises and no hidden fees.

Our AC Installation Process

We believe that transparency and communication are the foundation of great service. When you reach out to us for AC installation in Exeter, NH, the process begins with a comprehensive in-home consultation. One of our licensed technicians visits your property to evaluate your existing infrastructure, discuss your comfort preferences, and answer every question you have. We assess the condition of your ductwork, electrical connections, and thermostat setup to identify any issues that could affect the performance of a new system.

Once we have completed the assessment and you have selected the system that fits your needs and budget, we schedule the installation at a time that works for you. On installation day, our technicians arrive on time, protect your home with drop cloths and shoe covers, and get to work. The process typically involves removing the old equipment, preparing the installation site, mounting the new indoor and outdoor units, connecting refrigerant lines, verifying electrical connections, and testing the entire system for proper operation. We do not consider the job finished until airflow, temperature differentials, and refrigerant levels all meet manufacturer specifications.

What We Install

Modern air conditioning technology has advanced significantly over the past decade. Today’s systems offer higher SEER2 (Seasonal Energy Efficiency Ratio) ratings, variable-speed compressors, smart thermostat compatibility, and quieter operation than ever before. We install a wide range of cooling solutions tailored to different home configurations and budgets.

  • Central air conditioning systems remain the most popular choice for homes with existing ductwork, offering whole-home cooling with consistent temperature control across every room
  • Ductless mini-split systems are ideal for older Exeter homes that lack ductwork, room additions, or spaces where zoned cooling provides better efficiency and comfort
  • Heat pump systems provide both heating and cooling in a single unit, making them an increasingly popular choice in New Hampshire as technology improves their cold-weather performance
  • Hybrid systems pair a heat pump with a traditional furnace, automatically switching between electric and gas heating depending on outdoor temperatures for optimal efficiency

Energy Efficiency and Long-Term Savings

The minimum SEER2 rating for new air conditioning systems sold in the northern United States is now 13.4, but many of the systems we install exceed that baseline significantly. Higher efficiency equipment costs more upfront, but the energy savings compound over the life of the system. A homeowner upgrading from a 10-SEER unit to an 18-SEER system can reduce cooling energy costs by nearly 45 percent. We help you weigh the long-term savings against the initial investment so you can make an informed decision that makes sense for your household.

We also discuss available manufacturer rebates, utility incentive programs, and financing options during your consultation. New Hampshire utility companies frequently offer rebates for high-efficiency HVAC equipment, and these programs can significantly offset the cost of upgrading. Our team stays current on all available incentives so we can help you take full advantage of every opportunity to save.

Protecting Your Investment with Warranties

Every AC installation we perform is backed by our 2 year parts and labor warranty. This means that if anything goes wrong with the installation or the components we provided during that period, we take care of it at no additional cost. For customers who want even greater peace of mind, becoming a club member extends that coverage to a 3 year parts and labor warranty. Club membership also includes additional benefits like priority scheduling and routine maintenance visits that keep your system running at peak performance.

Routine maintenance is essential to protecting the investment you make in a new air conditioning system. Dirty filters, clogged drain lines, and low refrigerant levels can all diminish performance and lead to costly repairs if left unaddressed. We recommend annual tune-ups to catch small issues before they become big problems, and our maintenance plans make it easy to stay on top of your system’s health.

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.

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.

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.

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.

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

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.

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!

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

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. 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.

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!

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.

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.

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.
