In Pepperell, MA, the homeowner wanted efficient heating and cooling for better comfort throughout the home. Accutemp Engineering installed a 55K (5-ton) heat pump system with two ducted indoor units, duct kits, and a full duct layout to serve the first and second floors.

We set the outdoor unit on a new pad and stands, then ran line sets, control wiring, and power connections. Our team installed drains for proper condensate flow and set up remotes and controls for easy daily use. Inside, we built the duct distribution for balanced airflow. The first floor received 6–8 supply runs and 1 return. The second floor received 5–6 supply runs and 1 return.

To add reliable cold-weather heating, we installed a Hydro-Coil and connected it to the home’s existing boiler using PEX. We also included a heat strip for additional backup capacity when needed. After installation, we tested the full system to confirm safe operation, responsive controls, and consistent performance.

This Pepperell heat pump install shows how Accutemp supports homeowners across the Greater Boston region and nearby Massachusetts communities with smart HVAC upgrades.
