Project Overview

Jay Moody HVAC recently completed a partial-home heat pump installation for a historic 1835 home in West Boylston, Massachusetts, addressing its unique heating and cooling challenges.

The 7-bedroom home used a natural gas boiler to heat the first floor, relying on rising heat to warm the home’s second floor. Meanwhile, its attached two-story finished barn depended on a single wood stove for heating. During the summer, the home used inefficient and inconvenient window air conditioning units for cooling throughout the home. All in all, the home’s existing HVAC system resulted in inconsistent temperatures and overall discomfort throughout the home.

To provide a tailored solution, a Jay Moody HVAC degreed engineer thoroughly assessed the home’s needs and designed a hybrid system combining ducted and ductless Mitsubishi Hyperheat heat pumps. This 11-zone system, optimized for cold climates, integrates seamlessly with the existing fuel system, offering efficient heating in winter and cooling in summer. The home’s new HVAC system ensures year-round comfort while preserving the home’s aesthetics.

From the initial consultation to the final installation, Jay Moody HVAC’s team worked diligently to ensure a seamless and efficient process.

From the Client:

“We had such a fantastic experience with the team at Jay Moody. Ours was a complicated installation in an old farmhouse, and they managed to cover every space. They are fast, responsive, and incredibly professional. They weren’t the lowest bid for our job by a long shot, but this is seriously a case where you get what you pay for, and I would absolutely work with them again and cannot recommend them more highly.”

The Challenge

The West Boylston home presented several challenges stemming from its unique layout, current heating system, absence of ductwork and the homeowners’ desire to preserve its historic charm.

Without ductwork, the homeowners relied on inefficient, cumbersome window AC units to cool each room. Fuel heating was limited to the first floor, leaving the second floor and barn with inconsistent temperatures year-round. Additionally, certain areas, like the kitchen, lacked sufficient floor or wall space to accommodate ductless mini-split units, further complicating the design of an effective comfort solution for the space.

The Design

To meet the unique needs of this historic West Boylston home, Jay Moody HVAC designed and installed an 11-zone Mitsubishi Heat Pump System that combined ducted and ductless units. This innovative design ensured efficient, year-round comfort while accommodating the home’s layout and preserving its aesthetic appeal.

4-Zone System

The first multi-zone outdoor condenser served four key areas:

Barn: A floor-mounted Mitsubishi mini-split was installed on the first floor of the barn to minimize the impact on the space’s historic look, as its low positioning helps to blend with the area’s interior design. On the second floor, which is intended for future use as a family entertainment space, a wall-mounted mini-split was installed to ensure effective heating and cooling on both floors of the barn.

Kitchen: Due to space constraints and the kitchen’s high heat output, a small, ducted heat pump was installed, overcoming the limitations of competitors’ solutions that relied on airflow from neighboring rooms.

Primary Bedroom: A compact wall-mounted mini-split was installed in the first- floor bedroom to avoid oversizing and ensure optimal efficiency while heating and cooling the space.

7-Zone System

The second outdoor condenser addressed the remaining seven zones of the home:

Living Room and Dining Room: Ductwork was installed with a small air handler, seamlessly blending into the home’s design while meeting its heating and cooling demands.

Office and Upstairs Primary Bedroom: These rooms were equipped with wall- mounted Mitsubishi designer-series mini-splits, providing precise temperature control and a modern yet unobtrusive aesthetic.

Additional Bedrooms and Laundry Room: Each room was fitted with ceiling cassettes, which discreetly integrate into the ceiling while delivering efficient dual heating and cooling.

The heat pump system utilizes integrated controls designed to maximize energy efficiency and comfort. On the first floor, the heat pumps provide supplemental heating during milder conditions, seamlessly switching to the home’s original boiler system for added warmth during extreme cold. Meanwhile, the second floor and the barn are fully heated and cooled by the mini-split units, delivering consistent, independent climate control tailored to each space. This approach ensures year- round comfort while optimizing energy use throughout the home.

Project Execution

Jay Moody HVAC worked closely with the homeowners to deliver a seamless experience, from the initial in-home consultation to filing rebate and warranty paperwork.

  • In-Home Consultation: When the homeowners reached out for a free quote, Jay Moody HVAC’s degreed engineer conducted an on-site consultation to assess the home’s unique needs. The consultation began with a thorough discussion of the homeowners’ concerns, including comfort and efficiency challenges, and their goals for a new system. Detailed questions about lifestyle, aesthetic preferences and specific comfort priorities helped shape a system tailored to their needs.The engineer performed a Manual J calculation to precisely determine the home’s heating and cooling load based on 99% of local weather conditions, ensuring accurate system sizing for optimal performance. Working closely with the homeowners, a custom solution was designed to balance efficiency, comfort and the preservation of the home’s aesthetics.
  • Installation: Jay Moody HVAC’s skilled technicians began the installation with a detailed walkthrough to ensure alignment with the homeowners’ expectations. As a Mitsubishi Diamond Elite Contractor, the team utilized advanced training to deliver an expert installation and provided an extended 12-year warranty on the system.For minimal impact to the home’s aesthetics, all exterior work, including refrigerant lines and outdoor condensers, were positioned on the far side of the home. This placement ensured the home’s new system would not be visible from the street.Throughout the process, the technicians worked with meticulous care, maintaining a clean workspace and keeping the homeowners informed at every step. Upon completion, the lead installer conducted a thorough walkthrough, explaining system operation, efficiency tips and maintenance requirements to ensure the homeowners could maximize the system’s performance and longevity.
  • Mass Save HEAT Loan & Rebates: As a certified member of the Mass Save Heat Pump Installer Network (HPIN), Jay Moody HVAC designed and installed a system that qualified the homeowners for valuable incentives. Although the home used a municipal electric provider, it qualified for the Mass Save program through its Eversource natural gas service, allowing the homeowners to take advantage of the Mass Save HEAT Loan, a substantial rebate, and a federal tax credit.To make the process as hassle-free as possible, Jay Moody HVAC guided the homeowners through the HEAT Loan application, handled all rebate paperwork, and even filed the system warranty. Our goal is to ensure homeowners can enjoy their new system with minimal effort while maximizing their savings.

The West Boylston homeowners now enjoy year-round efficient comfort, with cooling to tackle hot Massachusetts summers and consistent heating to end winter temperature struggles. Jay Moody HVAC is grateful to the homeowners for trusting us to design and install a system tailored to their needs, creating a comfortable, hassle-free living environment for the whole family.
