ComfortAir HVAC Software is an advanced and efficient application whose main function is to assist users in calculating the hourly load of various air conditioning machines, using information from weather stations all over the world.

After installing the program on their systems, users can start new projects right away, either by clicking on the ‘New’ button in ComfortAir HVAC Software’s ribbon or by selecting the equivalent option from the ‘File’ menu.

The ‘General Project Data’ option from the ‘Project’ menu enables users to enter the name, designer, address and date of the current record, then choose a weather location that is closest to theirs.

The next step consists of setting the frequency levels for the ‘Cooling Outside Temperatures’ and the ‘Heating Outside Temperatures’ by checking the preferred option. Moreover, users will need to input the inside design conditions for cooling and heating, specifically the number of degrees.

Subsequently, users will need to choose a ‘Description of Roof Construction’ from the thirteenth offered alternatives, then set the proper answer for a series of questions meant to determine the type of space the project is for. Similarly, they will need to opt for a wall construction group, the number of hours during which the lights are on and configure their functioning schedule.


Additional information refers to the total hours of occupancy and the number of individuals in the room, the used appliances and laboratory equipment, as well as the run duration of power and electronic equipment. Users will also need to select the glass type for the building envelope along with several other related details, finally completing the configuration of the project, so users can obtain the results they are after.

Limitations in the unregistered version

  • Only one weather station out of the 1,989 supported in the full version

Ive been commercial/industrial HVAC my entire carrier. Ive worked on my share of residential including doing enough side jobs mostly family and friends where Ive decided what size of a/c and furnace to install in 'others' homes with great success. I must admit it has been by the old fashion way of 'rule of thumb' (1 ton per 5 to 600 sq.ft. Depending how tight the homes are built). HOWEVER now that it's my own home I'm sizing up I want it perfect. Im terrible I know, but honest. Does anyone have a favorite software program or app. They like to do the load calc on a residential home. Preferably a free one.
