A heat-pump project is more than choosing an outdoor unit: the design has to match the home, existing distribution system, and local climate. Current local prices are unavailable here, so request comparable written bids that explain the equipment, installation work, and assumptions.
Define the system and the work
Air-source heat pumps move heat between indoors and outdoors and can provide both heating and cooling. A proposal should identify whether the design is ducted, ductless, or a hybrid with a separate furnace, and describe the indoor and outdoor equipment included.
Ask whether the scope includes removal and disposal of existing equipment, refrigerant-line work, condensate handling, electrical connections, controls, duct modifications, startup, and homeowner orientation. A low headline bid can omit work that another contractor has included.
- Ask for the make, model, capacity, and matched indoor/outdoor combination.
- Confirm who handles permits, inspections, and commissioning records.
Understand the design basis
Equipment sizing should be supported by a load calculation based on the house rather than only the size of the old unit. The contractor should discuss insulation, air leakage, windows, room-by-room comfort concerns, and the design temperatures used.
For a ducted system, ask for an assessment of duct condition, airflow, and static pressure. For ductless equipment, have the installer explain indoor-head locations and how rooms outside those zones will be served.
Compare proposals and plan the handoff
Efficiency labels and performance data can help compare equipment, but they do not replace a sound design or competent installation. ENERGY STAR explains heat-pump product criteria; ask bidders to identify the exact qualifying model rather than relying on a brand name.
Current local prices are unavailable here. Collect written bids based on the same rooms, equipment approach, electrical work, and exclusions; compare warranty terms, schedule, commissioning, and the process for resolving unexpected conditions.
- Request a written description of any backup-heat strategy and its controls.
- Ask how the contractor will verify airflow, refrigerant charge, and system operation.
