The central air conditioning system of this 1980s home in Carlisle, Massachusetts recently failed. While frustrating for the homeowners, it proved the perfect opportunity to evaluate the home’s entire HVAC system and transition away from fuel-based heating. Given their efficiency and dual heating and cooling capabilities, heat pumps seemed to be the logical solution. However, the homeowners were concerned how heat pumps might affect the home’s aesthetic appeal. Jay Moody HVAC was entrusted with the task of designing and installing a high-quality central heat pump system that would meet the functional and aesthetic needs of the Carlisle Home.
“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.”
Like many homes in Massachusetts, the Carlisle residence presented a unique set of comfort, efficiency and aesthetic needs tailored to the homeowners’ lifestyle and preferences. The homeowners sought a more energy-efficient and sustainable HVAC system that would heat and cool the home effectively. In addition to efficient heating and cooling, the homeowners prioritized quiet system operation and discreet placement of any equipment located on the outside of the house.
The home’s design, because of the area’s wetlands, resulted in a distinctive layout that restricted available space in the basement. It was essential that the selected system fit comfortably in this space while providing enough room for future maintenance and technician access.
Additionally, the home’s electrical service was already at capacity due to a kitchen designed for entertaining, complete with multiple cooktops and ovens. To avoid the cost, inconvenience and aesthetic impact of an electrical service upgrade, the homeowners wished for the new HVAC system to be fully compatible with their existing electrical service.
To meet the homeowners’ priorities, Jay Moody HVAC designed a custom HVAC system that integrates a central heat pump system, a SPAN smart electrical panel and a fuel-based backup heat source.
The central heat pump system features a Bryant Evolution air-handler with a HyrdoCoil connected to a Buderus boiler. This system leverages the home’s existing ductwork while newly installed, customized duct transitions ensure optimal airflow and performance.
Bryant Evolution was the equipment of choice due to its extremely quiet and efficient operation. To adhere to the aesthetic parameters of the home, Jay Moody HVAC worked with the customer to find the most discrete placement for the outdoor condenser, ensuring minimal visual impact.
To fully replace the home’s existing oil boiler with a larger heat pump system, the homeowners would have been required to power off one of the ovens during colder weather or complete an electrical service upgrade. To prevent this limitation, a slightly smaller heat pump system was installed. This setup allows the ovens to retain priority electrical demand, while the Buderus boiler provides supplemental heating on extremely cold days when the ovens are also operating.
The main challenge when designing this system was balancing the electrical needs of a whole-home heat pump system with the additional load from the kitchen, which is equipped for large-scale entertainment. Rather than upgrading from a 200-amp service to a 400-amp service – something the homeowners wanted to avoid for aesthetic and cost reasons- Jay Moody HVAC recommended the sleek and innovative SPAN smart panel. This advanced electrical panel effectively manages electrical consumption across the home’s circuits, prioritizing energy use according to the homeowners’ preferences and ensuring efficient operation of both the HVAC system and kitchen appliances.
Jay Moody HVAC’s engineer worked closely with the homeowners to fully understand their comfort and efficiency goals, designing a tailored system to meet those needs. From the initial consultation to the final installation, the team ensured am seamless experience, handling everything from system design to submitting rebate and warranty paperwork.
With the project now complete, the Carlisle homeowners can enjoy a more sustainable and efficient cooling system just in time for summer, as well as reliable heating throughout the colder months. The home’s new SPAN panel provides circuit-level control over electrical appliances and allows the homeowners to monitor their energy usage directly from their smart devices.
Best of all, the homeowners didn’t have to compromise on aesthetics, comfort or efficiency. Their new custom-designed heat pump system perfectly aligns with their needs, catering to both functionality and aesthetics.
