Water-Source Heat Pump Service in Greater Boston

Scott HVAC and Home Service provides professional maintenance, diagnostics, repair, replacement and installation of water-source heat pump systems throughout Greater Boston. We serve individual condominium owners, landlords, property managers, condominium associations, building owners and commercial facilities.

Water-source heat pumps are commonly found in condominium and apartment buildings, high-rise residential properties, office buildings, hotels, assisted-living facilities, schools, medical buildings and mixed-use properties. The individual unit is usually installed above a ceiling, inside a mechanical closet or within another interior utility space and connected to the building’s shared water loop.

What Is a Water-Source Heat Pump?

A water-source heat pump transfers heat between the conditioned space and a circulating building water loop. Unlike a conventional air-source system with an outdoor condenser, the complete heat-pump unit is generally located inside the building.

During cooling, the equipment removes heat from the space and transfers it into the water loop. During heating, it extracts available heat from that loop and delivers it indoors. Many buildings use a central boiler and cooling tower to maintain the proper loop temperature.

Accurate Diagnosis Matters

Water-source systems require an understanding of refrigeration, airflow, electrical controls, condensate management and the building’s shared water-loop system. A problem that appears to be a failed heat pump may instead be caused by insufficient water flow, a blocked strainer, an abnormal loop temperature, an airflow restriction or a control problem. Our diagnostic process is designed to determine whether the issue is within the individual heat pump or may involve the building’s central system.

Water-Source Heat Pump Replacement

When an existing unit is no longer dependable or economical to repair, we can evaluate and replace it with properly selected equipment. Replacement planning involves considerably more than matching the old model number.

• Heating and cooling capacity
• Horizontal or vertical equipment configuration
• Available electrical service
• Building water-loop and flow requirements
• Supply and return duct connections
• Unit dimensions, access and service clearances
• Condensate drainage and overflow protection
• Thermostat and control compatibility
• Access for removing and installing the equipment
• Building-management and condominium requirements

Complete Replacement & Installation

Our replacement and installation work may include removal of the existing equipment, water-piping and valve modifications, duct transitions, condensate improvements, electrical and thermostat connections, startup and operational commissioning, and coordination with property management or other licensed trades when required.

Every installation is tested to verify proper heating, cooling, airflow, drainage, water temperatures, controls and overall equipment operation. Qualifying installations are supported by our three-year workmanship warranty.

Information to Have Ready

When requesting service, please provide the building address, unit number, equipment model and serial number when available, and a brief description of the problem. Photographs of the equipment, access area and thermostat can help us prepare for the appointment. Because these systems connect to shared building infrastructure, property-management coordination may be necessary before shutting off water or accessing common areas.
