The Right System for the Way You Live
We size and configure equipment around the building—not around a one-size-fits-all package.
Single-Zone Mini-Splits
A dedicated indoor unit and outdoor heat pump for additions, bedrooms, finished basements, garages, offices, and problem comfort areas.
Multi-Zone Mini-Splits
One outdoor system serving multiple indoor zones for individualized comfort throughout the home.
Ductless Heat Pumps
Efficient heating and air conditioning without installing a full duct system.
Ducted Heat Pumps
Central heat-pump systems that use ductwork for whole-home heating and cooling.
Cold-Climate Heat Pumps
High-performance heat pumps selected and sized for reliable operation during New England winter conditions.
Commercial & Multi-Family
Heat-pump and ductless solutions for offices, retail, restaurants, apartments, property managers, and commercial facilities.
Installation, Replacement, Repair & Maintenance
Whether you are electrifying the whole home, adding comfort to one room, replacing an aging mini-split, or diagnosing a heat pump that is not heating or cooling correctly, Tandem can handle the complete mechanical scope.
Why Proper Design Matters
Heat-pump performance starts with sizing and system design. Oversized or poorly placed equipment can reduce comfort and efficiency. We evaluate the building, existing systems, electrical requirements, room layout, design temperatures, and comfort goals before recommending equipment.
