AC Installation Services in Barrington, NH

When summer temperatures in Barrington climb into the 80s and 90s with humidity levels that make outdoor activities unbearable, having a properly functioning air conditioning system becomes essential for comfort and health. At Paul the Plumber, we specialize in professional AC installation services that ensure your home stays cool and comfortable throughout the hottest New Hampshire summers. Our team of licensed technicians brings 22 years of experience to every installation project, combining technical expertise with the personalized service that comes from being a family owned and operated business.

Installing a new air conditioning system represents a significant investment in your home’s comfort and value. We understand that choosing the right system requires careful consideration of multiple factors including your home’s square footage, insulation quality, existing ductwork condition, and your family’s specific cooling needs. Our BBB accredited A+ rating reflects our commitment to helping homeowners make informed decisions through transparent up front pricing and honest recommendations based on what will work best for your unique situation.

Understanding Your AC Installation Options

Modern air conditioning technology offers several installation options to meet different home configurations and cooling requirements. Central air conditioning systems remain the most popular choice for whole-home cooling in Barrington, utilizing existing ductwork to distribute cooled air evenly throughout every room. These systems typically consist of an outdoor condensing unit containing the compressor and condenser coil, paired with an indoor air handler housing the evaporator coil and blower motor. The refrigerant cycles between these components, absorbing heat from inside your home and releasing it outdoors through a process of compression and expansion.

For homes without existing ductwork or those seeking zone-specific temperature control, ductless mini-split systems provide an excellent alternative. These systems connect one or more indoor air handling units to an outdoor compressor via refrigerant lines that require only a small hole through the exterior wall. Each indoor unit operates independently, allowing different family members to set their preferred temperatures in individual rooms while avoiding the energy waste of cooling unoccupied spaces. Our technicians have extensive experience installing both traditional ducted systems and modern ductless solutions, ensuring optimal performance regardless of which option suits your home best.

The Installation Process and Timeline

Professional AC installation involves multiple critical steps that ensure safe, efficient operation for years to come. The process begins with a comprehensive load calculation to determine the appropriate system size for your home. Undersized units struggle to maintain comfortable temperatures while running continuously, leading to premature wear and excessive energy consumption. Oversized systems cycle on and off too frequently, failing to properly dehumidify the air while creating uncomfortable temperature swings. Our licensed technicians use industry-standard Manual J calculations that consider factors including window placement, insulation levels, ceiling heights, and solar heat gain to specify the perfect capacity for your specific home.

Once we’ve determined the correct system size, installation typically takes one to two days depending on complexity. The first phase involves removing any existing equipment and preparing the installation sites. We install a new concrete pad or wall brackets for the outdoor unit, ensuring proper drainage and clearance from vegetation or structures. Inside, we mount the air handler or furnace, connect refrigerant lines, install new thermostats, and integrate the system with your existing ductwork or install new duct runs as needed. Electrical connections require dedicated circuits with appropriate amperage ratings, which our team handles in full compliance with local building codes. After completing the physical installation, we charge the system with the precise amount of refrigerant specified by the manufacturer, test all components, and calibrate the thermostat for optimal performance.

Energy Efficiency Considerations

Energy efficiency ratings significantly impact both your environmental footprint and monthly utility bills. The Seasonal Energy Efficiency Ratio (SEER) measures cooling efficiency, with higher numbers indicating better performance. While federal regulations currently require a minimum SEER rating of 14 for new installations in our region, we often recommend systems with SEER ratings of 16 or higher to maximize long-term savings. A high-efficiency system with a SEER rating of 18 can reduce cooling costs by approximately 35% compared to older 10 SEER units commonly found in homes built before 2006.

  • Variable-speed compressors adjust output based on cooling demand, maintaining consistent temperatures while using less energy than single-stage units
  • Smart thermostats learn your schedule and preferences, automatically adjusting temperatures when you’re away to reduce unnecessary cooling
  • Enhanced filtration systems improve indoor air quality while maintaining efficient airflow through the system

Maintenance and Warranty Protection

Protecting your AC installation investment requires regular maintenance to prevent breakdowns and maintain peak efficiency. Our comprehensive warranty coverage includes a standard 2 year parts and labor warranty on all installations, with the option to extend coverage to 3 years through our club membership program. This warranty protection provides peace of mind knowing that any unexpected issues will be resolved without additional expense. Regular maintenance visits allow our technicians to identify potential problems before they develop into costly repairs, clean critical components that affect efficiency, and ensure your system continues operating at manufacturer specifications.

Annual maintenance tasks include cleaning or replacing air filters, checking refrigerant levels and testing for leaks, cleaning evaporator and condenser coils, lubricating moving parts, testing electrical connections and capacitors, and calibrating thermostats for accurate temperature control. Our thousands of verified 5-star reviews across multiple review platforms consistently highlight how our maintenance programs help systems last longer while maintaining optimal performance throughout their service life.

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. 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. 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.

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

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!

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. 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!

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.

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.

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!

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.
