This 1850s antique farmhouse in Acton, Massachusetts, lacked ductwork for central air and relied on an inefficient gas boiler and four existing mini-split heat pumps, originally installed by another contractor. Jay Moody HVAC was tasked with converting the entire HVAC system to heat pumps and upgrading the water heater. The solution: a custom Mitsubishi Mini-Split system, offering efficient heating and cooling with discreet placement to preserve the home’s historic charm alongside a hybrid-electric water heater (also known as a heat pump water heater).
“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.”
This historic Acton home presented several challenges due to its age and lack of ductwork. The absence of air conditioning led to inconsistent temperatures throughout the house and the home’s existing heating system proved to be inefficient. Additionally, several of the pre-installed mini-split heat pump systems had been poorly positioned by the previous contractor and the existing water heater was old and inefficient.
To eliminate the need for the home’s gas boiler, Jay Moody HVAC designed a custom 5-zone Mitsubishi mini-split system, seamlessly integrating with the existing 4-zone setup. For hot water needs, a hybrid-electric water heater was installed, ensuring energy efficiency. Additionally, the placement of the existing mini-split units was optimized to enhance both functionality and alignment with the home’s aesthetics.
The new 5-zone system consists of five Mitsubishi mini-split units connected to a single multi-zone outdoor condenser. Chosen for their cold-climate heat pump technology and ductless design, Mitsubishi mini-splits are ideal for this application. As a Mitsubishi Diamond Elite contractor, Jay Moody HVAC ensures that all installations are backed by an extended 12-year equipment warranty.
The system includes a wall-mounted unit in the left bedroom, another in the right bedroom, a third in the home office, plus floor-mounted units in the kitchen and dining room. This multi-zone heat pump system effectively meets the home’s heating and cooling requirements.
To optimize the home’s existing setup, Jay Moody HVAC replaced the original AC-only Mitsubishi condenser with a new, more efficient multi-zone, cold-climate Mitsubishi condenser. The team relocated the kitchen’s floor-mounted unit to the living room, where it performed more efficiently. Wall-mounted units in the primary and second bedrooms were also reinstalled to ensure proper distribution.
In place of the home’s outdated indirect water heater, Jay Moody HVAC installed a hybrid-electric (heat pump) water heater to meet the home’s hot water demands more efficiently. This new system uses heat pump technology to provide consistent, energy-efficient hot water, contributing to the overall energy savings of the home.
Jay Moody HVAC’s engineers collaborated closely with the homeowners to fully understand their comfort and efficiency needs, designing a tailored system to meet those goals. From the initial consultation to the final installation, the team ensured a seamless experience, handling everything from system design to submitting rebate and warranty paperwork.
With the installation of their new ductless heat pump system, the Acton home now enjoys efficient heating and cooling, eliminating the need for the outdated, inefficient gas boiler. The new system offers zoned temperature control, allowing the homeowners to customize the temperature in each room. This not only enhances comfort but also reduces energy waste by avoiding the need to heat or cool unused spaces to maintain the overall home temperature. Additionally, the new water heater provides a more energy-efficient solution for the home’s hot water needs.
We are incredibly grateful to the homeowners in Acton for trusting Jay Moody HVAC with their heat pump project!
