What is the best HVAC design software?

Software programs for designing HVAC is crucial to your business if you are engineering, or installing systems that need to be designed to specifications. A properly designed HVAC system will operate efficiently and effectively. It can also be essential in estimating medium to large projects.

There are an array of heating and air conditioning computer design programs that you can get directly online or through a download. I've heard some businesses say they have not adopted design software in their business practice because they hear it is too complicated to use.

Unless you are an engineer looking for a specific program to integrate with your current engineering software (which you can find here), there are many other programs that have different learning curves. Some are so basic to use, by just adding in amounts or dimensions, where others will need a little time and attention to detail.

Software designers design their products to be user friendly. Most have detailed manuals and are customer support based.

Take the opportunity to look through the different design software offered on this web page. Some offer trial or limited versions. You may be surprised that they are much easier to learn and use than you think.

How Many ACCA Load Calculation and Design Manuals Are There?

In 1986, ACCA (Air Conditioning Contractors of America) released their Manual J [ANSI/ACCA 2 Manual J - 2016] load calculation format for residential HVAC applications. It was a success that started a trend for future standard calculation and design manuals. There is a Manual D [ANSI/ACCA 1 Manual D - 2016] for residential duct design. Manual N for commercial load calculations and Manual Q for commercial duct design (low velocity and low pressure design). For air and hydronic balancing and testing there is a Manual B. A Manual Zr [ANSI/ACCA 11 Manual ZR - 2020] for residential zoning systems. A Manual T for air distribution fundamentals. For residential equipment selection use Manual S [ANSI/ACCA 3 Manual S - 2014]. This is different from a Manual RS which covers special design steps and principles to install residential HVAC systems for today's homeowner. Commercial systems selection would be Manual CS. There is a Manual H for heat pump systems. A Manual P for psychrometrics (relative humidity and moisture). There is one for HVAC design for swimming pools and spas: Manual SPS [ANSI/ACCA 10 Manual SPS - 2011 (RA 2017)]. Many manuals are compliant with American National Standards Institute (ANSI) standards and national building codes. ACCA produces other quality books and design materials. They are a great asset to the HVACR industry and their website can be found here.
