The HVAC Sizing Tool allows HVAC contractors to calculate room-by-room or zone-level heating and cooling loads for existing and new small buildings. This unique online tool does the job of much more expensive industry software programs in far less time. HVAC Sizing Tool users can go from accurately sizing load and demand to printing out design specifications in about 30 minutes.

The HVAC Sizing Tool is based on ACCA Manual J and D, with common assumptions used to speed data entry. It was tested at a national level and demonstrated consistent results with other ACCA-approved software and ACCA Manual J and Manual D calculations. The Northwest Energy Efficiency Alliance (NEEA) developed the tool in collaboration with CLEAResult Inc. to support energy efficiency programs of northwest utilities. In 2020, it was made available for anyone to use without charge, though the utility incentive programs connections are only available in Oregon, Washington, Idaho and Montana.
