A Manual N Calculation can help your business operate safely and efficiently

Your commercial building’s energy efficiency depends on having the right sized HVAC‌ system. Call Balanced Comfort for an expert “Manual N”‌ calculation to determine if your HVAC equipment is fit for your business’ unique needs, potentially saving you money from wasted energy costs.


What is a “Manual N” Commercial Load Calculation?

Developed by the Air Conditioning Contractors of America (ACCA), Manual N commercial load calculations are designed to instruct building owners (and their contractors) on how to meet the complicated heating and air conditioning requirements for commercial buildings.

If the size of your HVAC system is too small, it won’t be able to maintain your building at a comfortable temperature. Too-small units work harder than they’re built for, and tend to have short lifespans.

On the other hand, a system that’s too big will quickly produce too much heating and cooling, even on the lowest setting. This can lead to “short cycling,” when the equipment constantly shuts on and off to correct itself.

Units that are too small or too large both lead to unnecessarily high energy bills and undue wear-and-tear on your existing HVAC system.Having a Manual N‌ calculation performed will ensure that you are meeting current building codes, keeping the occupants safe and comfortable, and keeping the utility bills as low as possible.


What does a Manual N‌ calculation involve?

While performing a Manual N‌ calculation, our expert staff will assess the physical and thermal characteristics of your building, including:

  • Size of the building
  • Number of doors and windows
  • The efficiency of the sealing
  • Expected climate

We also factor in the latest developments in the commercial construction industry such as the use of new materials, assembly, operational requirements, and more. We’ll then work with you or your designated architect to calculate how much heating or cooling your building needs.

We offer a quick 1-2 day turnaround on your completed calculation. Call us for a same-day quote on your Manual N‌ calculation today.
