When you are having a central air system installed into your home, it can be a lot more complicated than simply finding room in the walls and attic of your house for all the necessary equipment. Part of the challenge is also making sure that the system you’ve chosen can do an adequate job of heating and cooling your home in even the most extreme weather. Having to go back in and make changes after the fact can get expensive, so you want to be sure to get it right the first time. That’s why it’s in your best interest to choose a heating, ventilation, and air conditioning (HVAC) contractor that has the software to be able to conduct a Manual J load calculation.
Manual J is a system of calculating HVAC loads for different structures. Contractors used to do these calculations on paper, but that made them prone to mathematical mistakes. But in 1986, the Air Conditioning Contractors of America (ACCA) released the very first Manual J load calculation software, which suddenly made it much easier for HVAC contractors to make quick and accurate calculations in order to design the perfect HVAC system to put in the structures they were working with.
Some contractors are still resistant to incorporating software into their business model to this day. The construction industry has been notoriously technology-shy in some areas, and some of the older contractors have stubbornly refused to make use of Manual J load calculation software. But this means that they’re more prone to making mistakes in their calculations, which could mean more money spent on the part of their customers, who will have to pay to have an adequate system installed into their homes. Using an ACCA-approved software can prevent these unwanted, additional costs and help to make sure that the job gets done right the first time.
Using an ACCA-approved Manual J load calculation software also allows the (HVAC) contractor to calculate the load of a structure more quickly, so that work can begin as quickly as possible. The contractor is able to do his work much faster when he can trust that his calculations are accurate. This saves a lot of time for the contractor and for the homeowner. It’s no wonder that so many homeowners have begun to insist on working only with HVAC contractors who have access to ACCA-approved software. It’s a sign of smooth sailing to come.
