Learn how a tailored Mitsubishi heat pump installation provided efficient cooling and heating for this historic Harvard, MA home, enhancing comfort without compromising its original character.
Harvard, Massachusetts is filled with historic New England homes that require thoughtful, efficient HVAC upgrades. Jay Moody HVAC installed a Mitsubishi ductless heat pump system in this 1780 Village Colonial in Harvard, MA, providing the homeowners with modern comfort without compromising the home’s charm.
The new Mitsubishi mini-split system delivers zoned cooling for the home’s most used rooms and supplemental heating during colder months. Additionally, our team replaced the home’s aging, end-of-lifespan oil boiler with a more efficient model to restore reliable whole-home heating.
This project demonstrates how heat pumps can be successfully integrated into historic Harvard, MA homes while enhancing comfort and energy efficiency.





“I have had a very positive experience with Jay Moody HVAC. It started with the first onsite visit to quote our three mini-split heat pump installations. The owner had obvious wisdom on the needs of our older home and he offered an intelligent quote at the end of the visit. The installation was fast because of the hard work and expertise of the team. Great care was shown for the fit and finish of the installation on top of the electrical and plumbing needs. (It works great.) Before, during and after, Jay Moody HVAC has provided excellent administrative and technical telephone support. Highly recommend.” – Craig M.
The homeowners wanted an effective cooling solution for three frequently used rooms, but the project needed to overcome two key challenges common in historic Harvard, MA homes:
Like many 18th-century Massachusetts homes, this Village Colonial relied on window AC units and fans in the summer and faced inconsistent room-to-room temperatures in the winter. Installing ductwork would have been costly and intrusive to the home’s build. At the same time, the homeowners wanted to minimize the impact of visible exterior changes such as exposed refrigerant lines.
A thoughtfully designed 3-zone Mitsubishi ductless heat pump system provided the ideal solution—delivering efficient heating and cooling with minimal impact on the structure of this historic Harvard, MA home.


This 3-zone ductless design also includes Kumo Cloud integrated controls, allowing the mini-splits to communicate with the home’s existing fuel-based heating system. This setup meets Mass Save’s partial-home heat pump rebate requirements while giving the homeowners flexible, room-by-room comfort.
In a later phase, Jay Moody HVAC replaced the home’s outdated boiler, which had reached the end of its lifespan. The new Buderus boiler now provides dependable, whole-home heating during New England’s coldest months.

Comfort and efficiency are not one size fits all, which is why Jay Moody HVAC focuses on solutions tailored to each home’s unique needs. Our comprehensive process begins with a detailed in-home consultation and continues with full homeowner support through installation, equipment warranties, registration and ongoing system maintenance.
Jay Moody HVAC’s owner Leo Sharkey, a degreed engineer with a Master’s in Mechanical Engineering, partnered closely with the Harvard, MA homeowners to design an HVAC solution that delivered year-round comfort while respecting the property’s historic character. Leo evaluated multiple layout options to determine which system design best addressed the homeowners’ goals: improved cooling, efficient supplemental heating, and minimal visual impact.
During the initial consultation, Leo performed a Manual J Calculation while in the home. This design process ensures proper system sizing—critical in Harvard’s climate, where heat pumps must perform efficiently during both hot summers and cold New England winters.
After comparing several equipment options, Mitsubishi Electric was selected for its proven cold-climate performance, high efficiency and sleek aesthetic. The floor-mounted indoor units blended seamlessly into the home’s common areas, offering modern comfort without disrupting the historic interior.
This engineer-led, science-backed design process reflects Jay Moody HVAC’s commitment to providing homeowners with tailored, data-driven heat pump solutions.
With the design finalized, the Jay Moody HVAC installation team brought the plan to life with thoughtful attention to the home’s structure and style. Each mini-split unit was installed to support optimal performance while preserving the home’s historic charm.
The line-set routing on the exterior was expertly mapped to maintain a clean, unobtrusive appearance—an important consideration for homeowners in historic communities like Harvard, Massachusetts. The three outdoor condensers were discreetly tucked away on pads and stands along the sides and rear of the property.
Inside, the combination of wall-mounted and floor-mounted Mitsubishi units delivered targeted comfort with minimal disruption to the home’s interior. Jay Moody HVAC’s installation team worked with great care, protecting the workspace, keeping the home clean and communicating clearly with the homeowners throughout the project.
Before completing the job, the lead technicians provided a full walkthrough of the new heat pump system. They showed the Harvard, MA homeowners how to operate their equipment, adjust comfort settings and follow best practices for maintenance and long-term performance.
This Harvard, MA heat pump installation qualified for the Mass Save Heat Pump Rebate Program, which offers generous incentives to homeowners upgrading to high-efficiency equipment. Jay Moody HVAC’s team is well versed in Mass Save requirements and outlines all available rebates and energy incentives directly in the written quote during the initial consultation. To make the process simple, our team completed the rebate application on behalf of the homeowners, alleviating confusing paperwork and reducing stress. The system also qualified for a Federal Energy Tax Credit, providing additional savings.
In addition to energy incentives, the homeowners received strong warranty protection. Jay Moody HVAC provides a two-year workmanship warranty on all installations. As a Mitsubishi Diamond Elite Contractor, Jay Moody HVAC’s mini-split installation also qualified for a 12-year equipment warranty. Our team completed the full warranty registration process to activate coverage.
When the homeowners later replaced their outdated boiler, a Buderus high-efficiency boiler was installed. Jay Moody HVAC also submitted the warranty for the new boiler to give the homeowners complete peace of mind for their whole-home heating system.
This Harvard, MA heat pump installation showcases how modern ductless heat pump systems can be thoughtfully integrated into historic New England homes without compromising comfort, efficiency or aesthetic appeal. Through an engineer-led design process, precise in-home Manual J calculations and careful installation practices, Jay Moody HVAC delivered a high-performance heating and cooling solution that supports the homeowners year-round.
The combination of targeted cooling, supplemental heating, an efficient boiler replacement and valuable energy incentives provided long-term comfort and financial savings. With strong warranties and full rebate support, the homeowners can rely on their new systems for many seasons to come.
For Harvard, MA homeowners considering a heat pump installation, this project is a strong example of how Jay Moody HVAC pairs technical expertise with thoughtful customer care to design solutions that fit both the home and the family who lives in it.
