Professional AC Installation Services in Amherst, NH

When summer temperatures soar in Amherst, NH, having a reliable air conditioning system becomes essential for maintaining comfort in your home. At Paul the Plumber, we specialize in comprehensive AC installation services that ensure your cooling system operates efficiently for years to come. Our family-owned and operated business has been serving the greater Nashua area, including Amherst, for 22 years, building a reputation for quality workmanship and exceptional customer service. We understand that investing in a new air conditioning system represents a significant decision for homeowners, which is why we provide upfront pricing and detailed consultations to help you make the most informed choice possible.

Our BBB accredited status with an A+ rating reflects our commitment to treating customers like family throughout every installation project. We recognize that each home in Amherst has unique cooling requirements based on factors such as square footage, insulation quality, window placement, and sun exposure patterns. Our licensed technicians conduct thorough assessments to determine the optimal AC system size and configuration for your specific needs, ensuring maximum efficiency and comfort while avoiding the common pitfalls of oversized or undersized units that plague many installations performed by less experienced contractors.

Understanding AC System Sizing and Selection

Proper sizing stands as the foundation of any successful AC installation project. An oversized unit will cycle on and off frequently, leading to increased wear on components, higher energy bills, and inadequate humidity control that leaves your home feeling clammy despite being cool. Conversely, an undersized system runs continuously without achieving desired temperatures, resulting in excessive energy consumption and premature system failure. We perform detailed load calculations considering your home’s specific characteristics, including ceiling height, insulation levels, window efficiency, and typical occupancy patterns to determine the precise cooling capacity required.

Modern air conditioning systems offer various efficiency ratings measured by SEER (Seasonal Energy Efficiency Ratio) standards. Current federal regulations require new AC units to achieve minimum SEER ratings of 14 in northern climates like New Hampshire, though we often recommend systems with ratings of 16 or higher for homeowners seeking optimal energy savings. Higher SEER ratings translate directly to lower operating costs, with some high-efficiency models reducing cooling expenses by up to forty percent compared to older systems. We help you evaluate the long-term cost benefits of different efficiency levels, considering factors such as your typical usage patterns, local utility rates, and available rebate programs that can offset initial investment costs.

The Installation Process and Timeline

Our AC installation process begins with a comprehensive home evaluation where we assess existing ductwork, electrical capacity, and potential equipment locations. This initial assessment typically takes one to two hours and allows us to identify any infrastructure updates needed before installation begins. We examine your current electrical panel to ensure adequate capacity for the new system, as modern air conditioners often require dedicated circuits and specific voltage configurations. If ductwork modifications prove necessary, we provide detailed explanations of required changes and their impact on system performance and efficiency.

Installation day activities follow a systematic approach developed through thousands of successful projects across Derry, Londonderry, Nashua, and Hudson. Our background-checked technicians arrive with all necessary equipment and materials, protecting your home’s interior with drop cloths and floor runners before beginning work. The physical installation typically requires six to eight hours for standard replacements, though complex configurations or extensive ductwork modifications may extend this timeline. We remove old equipment responsibly, ensuring proper refrigerant recovery according to EPA regulations, and recycle components whenever possible to minimize environmental impact.

Key Components of Quality AC Installation

Professional AC installation involves multiple critical components beyond simply placing the unit and connecting refrigerant lines. Proper refrigerant charging requires precise measurements and adjustments based on line length, ambient temperature, and manufacturer specifications. Incorrect refrigerant levels remain one of the most common causes of poor system performance and premature failure, yet many contractors rush through this crucial step. We utilize digital gauges and temperature sensors to ensure optimal refrigerant charge, verifying system pressures and superheat/subcooling values meet manufacturer requirements.

  • Ductwork sealing and insulation: preventing cooled air loss through leaks and thermal transfer
  • Condensate drainage systems: ensuring proper water removal to prevent mold and structural damage
  • Thermostat programming and calibration: optimizing comfort settings and energy efficiency
  • Air filter selection and installation: balancing filtration effectiveness with system airflow requirements
  • Electrical connections and safety controls: protecting equipment and ensuring reliable operation

Warranty Protection and Ongoing Support

We back all our AC installation work with a comprehensive two-year parts and labor warranty, demonstrating confidence in our workmanship quality. Club members receive extended three-year coverage, providing additional peace of mind and protection for your investment. These warranties cover both equipment failures and installation-related issues, ensuring you won’t face unexpected repair costs during the coverage period. Our thousands of verified five-star reviews across multiple platforms reflect our dedication to standing behind our work and addressing any concerns promptly and professionally.

Regular maintenance plays a crucial role in maximizing your new AC system’s lifespan and efficiency. We offer comprehensive maintenance programs designed to identify potential issues before they develop into costly failures. These programs include seasonal tune-ups, filter replacements, coil cleaning, and performance testing to ensure your system continues operating at peak efficiency throughout its service life. Our service with a smile approach means we’re happy to help with any questions or concerns that arise after installation, treating every service call with the same care and attention we’d provide for our own family members.

Making the Right Investment for Your Home

Choosing Paul the Plumber for your AC installation in Amherst means partnering with a company that values integrity and reliability above all else. We care deeply about ensuring each customer receives the perfect cooling solution for their specific needs and budget. Our upfront pricing eliminates surprises, allowing you to make informed decisions without pressure or hidden costs. We recognize that AC installation represents a significant investment, which is why we take time to explain all available options, including financing programs that can make high-efficiency systems more accessible.

Energy efficiency improvements in modern AC systems can generate substantial savings over time, often paying for themselves through reduced utility costs within several years. New Hampshire homeowners typically see cooling cost reductions of twenty to thirty percent when upgrading from systems installed before 2006. Additionally, improved humidity control and air filtration capabilities of modern systems contribute to better indoor air quality, benefiting family members with allergies or respiratory sensitivities. We help you understand these benefits and calculate potential savings based on your specific usage patterns and local utility rates, ensuring you make the most cost-effective decision for your long-term comfort and financial wellbeing.

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

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.

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.

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.

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!

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.

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.

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.

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!

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.

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.

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

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
