Air conditioner manual j calculation

The correct way to size an air conditioning system is with Manual J, a protocol developed by the Air Conditioning Contractors of America (ACCA). Manual J HVAC load calculations determine how much heating and cooling a house actually needs.

A load calculation program based on Manual J, designed to be quick and easy to use. It calculates the amount of heating and cooling BTU's needed for the whole house (Block Load) or a room by room load. Select a State or Province; afterwards you will then be given a choice of cities, airports or other major locations. ACCA’s Manual J load calculation is part of the design process of a new HVAC system. By following the Manual J methodology, HVAC system designers are able to accurately determine the total amount of heat that is lost through the exterior of a home during the cooler months, and the total amount of heat that is gained through the exterior of a home during the warmer months. In short, Manual J is the protocol that is used in order to determine the correct amount of heat that is needed to keep a house warm for its occupants, and the amount of cold air required in order to cool it when needed. The Manual J Calculation gets complicated oftentimes and requires good knowledge of the technique. This is why contractors developed rule of thumb methods like the simple BTU calculator which you can use above.

A Manual-J load calculation is a protocol for determining the right sized air conditioner for your home. It was developed by the Air Conditioning.
