Confirm whether the listing is a complete system or an individual component. Match the full model numbers, capacity, voltage, refrigerant, generation and included equipment against current MRCOOL documentation.
Plan electrical work, line sets, drainage, mounting and freight access before ordering. For multi-component systems, verify the exact approved combination—not only the family name.
Read planning guides →Ask an equipment question →Use these original research paths to frame the purchase, then verify the exact model in current MRCOOL documentation and applicable requirements for the installation address.

Choose a state guide →Central HVAC pages include complete systems and individual components. A heat pump, air handler, coil or furnace may have a similar family name without being an approved rated match.
Review the complete equipment match, capacity, voltage, electrical requirements, cabinet orientation and dimensions, duct needs, efficiency certification where applicable, controls and installation documentation before ordering.
Review the product title, included-components section, product images and exact models. A family name or capacity alone does not prove that indoor and outdoor equipment are both included.
Do not assume cross-generation compatibility. Confirm the complete combination in current MRCOOL documentation or obtain model-specific evidence before ordering.
No. Square footage is only one input. Climate, insulation, windows, ceiling height, orientation, occupancy and internal loads should be considered in a proper load calculation.
Available shipping methods and charges are shown at checkout for the order and destination. Large equipment may require additional freight-access planning before purchase.
