Summary
Cool Calc offers a web-based solution for HVAC load calculations, providing ACCA-approved Manual J, S, and D capabilities at a fraction of the cost of traditional desktop software. Its unique satellite-image map tracing feature simplifies data entry, making it a popular choice for smaller contractors and DIY enthusiasts. TL;DR Verdict: Cool Calc is an affordable, cloud-based tool ideal for residential HVAC projects, though it may lack depth for complex commercial applications.
What Cool Calc Does Well
Cool Calc excels in providing an accessible and cost-effective solution for HVAC load calculations. Its cloud-based nature means that users can access the software from any device with a browser, eliminating the need for expensive desktop installations. This flexibility is particularly beneficial for contractors who are frequently on the move or who prefer to work from various locations.
One of the standout features of Cool Calc is its satellite-image map tracing capability. This feature allows users to outline a building's footprint directly on aerial imagery by simply dropping a pin on the home's address. This innovative approach significantly speeds up the data entry process, enabling faster and more accurate load calculations. For HVAC contractors dealing with multiple projects, this can be a substantial time-saver.
Cool Calc's ACCA approval ensures that its outputs are recognized by code officials, providing peace of mind for contractors who need to meet regulatory standards. The software supports room-by-room and block load calculations, multi-system homes, and customizable design conditions, making it versatile enough for a wide range of residential projects. Additionally, the free tier offers basic load calculations, making it accessible to homeowners and DIYers who may not require full ACCA certification.
Where It Falls Short
While Cool Calc offers a robust set of features for residential projects, it may not be the best fit for more complex commercial applications. The software lacks the depth and advanced customization options found in more comprehensive tools like Wrightsoft or Elite. For contractors who frequently handle large-scale commercial projects, these limitations could be a significant drawback.
Another area where Cool Calc falls short is in its equipment records. The software has fewer manufacturer equipment records compared to its competitors, which may necessitate additional research or manual input for contractors who require specific equipment data. Furthermore, the lack of 3D visualization capabilities might be a limitation for users who prefer a more detailed visual representation of their projects.
Some advanced customization options in Cool Calc require workarounds, which could be cumbersome for users who need specific features or configurations. While the software is generally user-friendly, these limitations may pose challenges for contractors with unique project requirements.
Pricing
Cool Calc is priced at $100 per month, offering a more affordable alternative to traditional desktop software like Wrightsoft or Elite. The free tier provides basic load calculations, making it an attractive option for homeowners and DIYers who do not need full ACCA certification. This pricing structure allows smaller contractors to access professional-grade tools without a significant financial investment.
Who It's Best For
Cool Calc is particularly well-suited for smaller HVAC contractors who focus on residential projects and need a cost-effective, ACCA-approved solution. Its ease of use and fast data entry make it an excellent choice for contractors who manage multiple projects and require quick, accurate calculations.
Energy auditors and home performance professionals will also find Cool Calc valuable, as it provides the necessary tools to perform detailed load calculations without the complexity or cost of more advanced software. Additionally, homeowners and DIY enthusiasts can benefit from the free tier, which offers basic load calculations for personal projects.
Bottom Line
For HVAC contractors seeking an affordable, cloud-based solution for residential load calculations, Cool Calc offers a compelling package. While it may not have the depth required for complex commercial projects, its ACCA-approved outputs, innovative map tracing feature, and flexible pricing make it an attractive option for small to midsize shops. Overall, Cool Calc provides the essential tools needed to size heating and cooling systems efficiently and effectively.
