- New Construction & Custom Ductwork
Built Right From the Start.
Full HVAC design and installation for new construction and custom ductwork fabrication across coastal Connecticut.
Getting HVAC right in a new build isn’t just about installing equipment — it’s about designing a system that works with the home’s layout, insulation, and load requirements from day one. A system designed correctly at the start performs better, costs less to operate, and requires fewer repairs down the road.
We work with homeowners, builders, and contractors across coastal Connecticut on new residential construction and custom ductwork fabrication. We handle the full scope — from initial load calculations through final commissioning.
How We Work

Load Calculation & System Design
We start with a full Manual J load calculation to determine exactly what your home needs. No guesswork, no oversizing — just a system designed to match the actual demands of the space.

Equipment Selection
Based on the load calculation and your goals — efficiency, budget, zoning — we recommend the right equipment. We work with Mitsubishi, Carrier, Bosch, and other major brands.

Custom Ductwork Fabrication
Our sheet metal specialist fabricates custom ductwork in-house to fit your specific layout. No off-the-shelf fittings where custom is needed.

Full Installation
Our licensed team handles all equipment installation, ductwork installation, electrical connections, and refrigerant lines from start to finish.

Testing & Commissioning
Every system is tested and commissioned before we hand it over. We verify airflow, temperature differentials, and system performance to make sure everything is working exactly as designed.
What's Included
Everything We Handle for New Construction & Ductwork

Residential New Construction HVAC
Full HVAC system design and installation for new residential builds — from single-family homes to multi-unit projects.

Custom Ductwork Design & Fabrication
In-house sheet metal fabrication for custom ductwork that fits your specific construction. No compromises on fit or airflow.

Load Calculations & Energy Modeling
Manual J load calculations to properly size every system we install. Oversized systems short-cycle; undersized ones never catch up.

Multi-Zone System Design
Zoned HVAC systems that give different areas of the home independent temperature control — designed into the build from the start.

Mitsubishi & Multi-Brand Systems
We install Mitsubishi mini-splits and ducted systems, Carrier, Bosch, and other major brands — whatever is right for the project.

Builder & Contractor Coordination
We work directly with your builder or general contractor to coordinate rough-in, inspections, and final installation around your construction schedule.
Why It Matters
HVAC is one of the most important — and most commonly rushed — systems in a new build. Getting it right from the start saves money and headaches for the life of the home.

Design First, Install Second
Most HVAC problems in new construction stem from poor design — not poor equipment. A load calculation takes time. Skipping it costs more in the long run.

Custom Ductwork Outperforms Generic
Off-the-shelf ductwork creates airflow restrictions and efficiency losses. Custom fabricated ductwork is designed for the space it serves.

S1 Licensed & Fully Insured
Every new construction project we take on is backed by our S1 Unlimited contractor license and full insurance. Required for permitted work — and the right way to do it.

One Team, Full Scope
We handle design, fabrication, and installation under one roof. No coordination gaps between a design engineer, a sheet metal shop, and an install crew.

Great guys - explained everything Steven YatesTrustindex verifies that the original source of the review is Google. Cameron is a very professional technician. He always explains what needs to be done in a way that I can understand. He provides me with any information that I need in a timely manner. I am happy to have him doing the work on my heating and air-conditioning systems. Brian FayTrustindex verifies that the original source of the review is Google. From the moment I placed a call to Benedetto and spoke with Judie, I had an amazing experience. Judie couldn’t be friendlier, professional and can-do. Joe Benedetto then spent a lot of time on the phone with me really evaluating what I needed, and asked for measurements and photographs. Once he came out for a physical review, he had already reviewed information I sent him and had some really good ideas. Fast forward to installation day and the crew who arrived were SO amazing! Clay & Jet. Friendly, professional, knowledgeable beyond expectations, and they took such care of our home! This was the best service experience I think I’ve ever had! I can’t wait for an opportunity to refer friends or neighbors to them! Honestly, this is a company that deserves 6 stars, but I only had the option of 1-5. This type of customer service experience should be studied in business school. Thank you Judie, Joe, Clay and Jet!! Timothy MillerTrustindex verifies that the original source of the review is Google. My Mom had a new gas furnace put in. Clay, Logan, Rafael and Tim were very courteous and knowledgeable. They were very efficient and a very clean job and I would highly recommend them.

The entire crew was professional, friendly and informative about the new system. They are exceptional representatives of their company. Highly recommend. christine bondTrustindex verifies that the original source of the review is Google. We have been with Joe for many years. We appreciate his integrity, professionalism and honesty. the work ethics he has is visible in all his employees, from the "put you at ease" ladies who answer the phones to the polite guys that show up to work on the system. We have never doubted his opinion. Joe is what we call "old school" meaning he speaks the truth and is dependable. Over the years as Benedetto heating and cooling has grown, he and his team have remained down to earth, he is a good teacher and it shows in his team members. If you have a heating or cooling problem or question, Benedetto H/C is the team you want. Al & Christine Bond. Annie GourlieTrustindex verifies that the original source of the review is Google. Update: We continue to be so very pleased with Benedetto! We upgraded our two boiler systems with Benedetto, and we are very impressed! As we have come to expect from them - all of their service providers are always professional and respectful. They were timely and exceptional at communicating during the install. They left our house spotless, installed a pristine and impressive looking system that is a site to behold! And we believe we got the value for our money. Clay, Rafael, Logan, Ben, Justin and Joe Benedetto himself were polite, considerate and professional during the entire length of the project. I would not hesitate to hire them again and will continue to recommend them! ---------------------------------------- It is rare to find such professionalism in today's market! Both Clayton and Shawn are consumate professionals who respect your home, and provide THOROUGH and EXPERT service! They take the time to educate you, and provide transparent, reasonable quotes prior to doing any work. We have two old Buderus systems, and we've been looking for years to find someone knowledgeable about our systems. They did a complete overhaul to get us functioning properly. And the best part is - I trust them. We will absolutely be loyal customers from here on out! Thanks, Clay and Shawn!
