The Air Conditioning Contractors of America (ACCA) is the largest organization of heating, ventilation, and air conditioning (HVAC) contractors in the United States. As such, it’s committed to always highlighting the latest trends in the industry, and for providing HVAC contractors with access to cutting-edge resources that allow them to be the best at their jobs. In 1986, they created a software program that allowed HVAC contractors to quickly and accurately calculate the load of a house. But, since then, many imitators have produced their own versions of Manual J load calculators. So, now, HVAC contractors and their customers have to decide how important it really is to choose an ACCA certified Manual J software.
The very first ACCA certified Manual J software was developed by Bill Wright, who was giving a graduate seminar on HVAC at the Massachusetts Institute of Technology (MIT) at the time. He partnered with the ACCA to create a software that was not only accurate and considered all of the possible needs of a home and of an HVAC contractor, but also kept in mind that the people who would be using this software would generally be new to this kind of technology, so it needed to be extremely user-friendly. And, so, the first-ever ACCA certified Manual J software was born. In fact, it was the first Manual J software ever created.
Many companies have tried to duplicate Bill Wright’s achievement in this area. There are many different software programs available on the market today that claim that they are just as accurate as an ACCA certified Manual J program. But none of the developers of these software programs have access to the same unique combination of tech savvy and HVAC experience that the ACCA does. The ACCA has a deep pool of experience to draw from, that not only helps to make their software user-friendly, but also allows for the continual improvement of this software’s usefulness. Most other programs are nothing but glorified calculators.
When you buy a Manual J calculation software, you want to be sure of its accuracy. You don’t just want it to do the math for you, but you want it to be programmed with information about what is and isn’t possible for an HVAC contractor to do when installing central air in a house. Only ACCA certified Manual J software has the backing of software engineers and real HVAC contractors alike.
