PROCALCS
If you have a small or medium commercial building that needs an HVAC load calculation, then Manual N is the way to go. Our team knows how to calculate your commercial heating and cooling load properly so that you end up with a system that’s correctly sized for your property.
New Commercial Buildings
If you’re constructing a new commercial building for your business, let us help you determine what size of HVAC system you will need. Manual N is very accurate for small- to medium-sized commercial properties, and it takes into account every factor, including number of windows, building orientation, and more. Modern commercial construction also involves lots of new materials and building methods, and we’ll ensure that everything is up to code for ventilation and comfort requirements.
Updating Older Buildings
If you have an older commercial building that needs an HVAC upgrade, our team can calculate the proper load for the property. We’ll take into consideration the age of the building, any updates that have been made that could affect the building’s R-value, and any new purposes for which the building will be used. For example, if you’re renovating an existing structure and transitioning it from a manufacturing center into an office building, you’ll want to make sure that the heating and cooling is properly sized.
Getting Started
In many commercial buildings, there are large open spaces and lots of rooms with similar designs. This can make calculating and planning your HVAC load much easier, and if you’re ready to get started, ProCalcs is here to help. We have the knowledge and expertise to handle any job, and we’ll make sure your commercial property is set up for success.
