Plan the complete project—not only the equipment.

Use these original guides as a starting point, then confirm the exact product manual, local requirements and qualified professional work where applicable.

01 · SizingBuild from a load calculation

Understand why climate, insulation, windows, occupancy and room use matter.

Read sizing guidance → 02 · InstallationPlan electrical, drainage and access

Review the project conditions that should be settled before equipment arrives.

Open installation planning → 03 · RefrigerantKeep generations and refrigerants matched

Do not assume indoor, outdoor or accessory components are interchangeable.

Review refrigerant changes → 04 · DocumentationSave model-specific records

Keep manuals, specifications, invoices, serials and applicable warranty terms together.

Use the document checklist → 05 · Video workshopWatch official MRCOOL demonstrations

Use product videos to supplement—not replace—the current installation manual.

Watch the video workshop → 06 · State planningVerify state and local requirements

Start with climate context and official regulatory gateways for all 50 states.

How to shop Products

A precise model match saves more time than a broad category match.

Accessories are model-specific even when their names look universal. Match the accessory model to the exact indoor or outdoor equipment, generation, refrigerant, voltage, connection type and current manufacturer documentation.

Measure the route and installation conditions before selecting line sets, drainage, mounting, controls or heat kits. Confirm which parts are included with the primary equipment so the order is complete without unnecessary duplicates.

Common buying questions

Products FAQs

How do I know whether a listing is a complete system?

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.

Can I match components from different MRCOOL generations?

Do not assume cross-generation compatibility. Confirm the complete combination in current MRCOOL documentation or obtain model-specific evidence before ordering.

Does square footage determine the correct system size?

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.

Where do I confirm shipping charges and delivery options?

Available shipping methods and charges are shown at checkout for the order and destination. Large equipment may require additional freight-access planning before purchase.
