New Construction HVAC Services

Trusted Heating & Cooling Installation Since 1988

At Brookside, we’ve been serving builders and property developers throughout New Hampshire, Southern Maine, and Northern Massachusetts communities since 1988. What began as a dedicated HVAC provider for new residential construction has grown into a full-service operation; however, new construction remains at the core of what we do best.

Whether you’re building a custom home, multifamily complex, or light commercial space, we provide expert HVAC system design and installation tailored to your building plans, timeline, and budget.

Heating & Air Conditioning System Installation

Custom-Designed for Comfort & Efficiency
Our licensed HVAC professionals work closely with contractors, architects, and project managers to design and install high-efficiency heating and cooling systems that meet the unique needs of each property. We use load calculations and floor plan analysis to ensure proper system sizing and placement providing consistent, reliable comfort and energy savings year-round. From single-family homes to multi-unit developments, we’re committed to delivering performance-driven solutions on time and within scope.

Ductwork & Ventilation Installation

Airflow That Works as Hard as You Do
Efficient airflow starts with the right ductwork. We design and install custom duct systems that support optimal airflow, reduce system strain, and enhance indoor air quality. Our attention to detail ensures leak-free installation, balanced air distribution, and compliance with local building codes and energy standards. Whether it’s rigid ducting, flex duct, or zoned ventilation systems, we deliver clean, efficient installs built to last.

Thermostat & Control Systems

Smart Control for Smarter Living
To complete your system, we offer a full range of thermostat and control options including programmable and smart thermostats compatible with mobile devices. These modern controls provide easy access to temperature management, increase energy efficiency, and offer remote monitoring capabilities to keep your home or property running smoothly even when you’re away. We’ll recommend and install the right controls to match your system and lifestyle.

The guys at Brookside did top notch work replacing our 24 y/o Weil-McLain. Dropped off the new Buderus unit and HTP tank on Tuesday, came back on Wednesday and had everything installed and the old unit removed by the time I got home from work. Easy process start to finish.

First person I hired to do work on my new home in NH. Great company. My 1st service call was the owner. Extremely professional and personable. Called to check on us a day later to make sure we were operating to standard. I highly recommend this company.

Go figure...my furnace decides to stop working as soon as the temperatures drop. I called this company, left a message with the call center, received a call back within a couple of hours, and an appointment was booked. The two gentlemen that came to service my furnace were super nice, and they even gave my dog the attention he so desperately craves every time he sees a human. Definitely recommend!

We've used Brookside to replace our HVAC this past summer and our oil furnace this month. They do what they promise and always have the best prices. We've suffered with bad ductwork in this house for 5 years. We're now enjoying even, toasty heating. And summers are cool and quiet! I highly recommend BROOKSIDE!
