A heat pump can be installed in a residence by drilling a hole to connect coils and wiring from the interior unit to the outdoor condenser unit. The outdoor unit should be placed on a concrete slab, and the air handler should be mounted inside the house.
The outdoor condenser unit of the heat pump should be positioned approximately one foot from the house with connectors facing toward the interior. The vents should not be obstructed by the home or shrubbery. The air handler plate should be mounted on an interior wall adjacent to the outdoor unit, and a three-inch hole should be drilled to feed coils and wiring from the interior to the exterior unit.
The gas line should be wrapped with insulation, and homeowners should use a conduit to connect the outdoor compressor unit to the indoor air handler. All connections should be tightened. A condensate drain with tubing should be connected to the refrigerant line, and the drain should routed to the home's main sewer drain.
When installing a heat pump, home owners may need to hire a professional electrician to install an electrical disconnect and a breaker for the heat pump that runs from the outdoor unit to the electrical panel.
