How Your HVAC System Size Affects Efficiency

For your commercial HVAC system to run at peak efficiency, it needs to be sized just right for your facility. If not, you could face issues, like higher energy bills or temperature fluctuations. Here’s why HVAC system size impacts efficiency and what goes into calculating the size of your HVAC unit.

HVAC systems that are too small or too large can cause several issues in your facility. For instance, if your HVAC unit is too small, it will need to run consistently to cool your indoor spaces. And, with a system that runs all the time, you’ll almost certainly notice a large increase in your energy bills.

If your HVAC unit is too large, on the other hand, it can cause short cycling, meaning it turns on and off frequently. Short cycling not only leads to higher energy bills, but it can result in hot and cold spots. It can also take a toll on HVAC system parts. Plus, because the system operates in short bursts, it won’t ever run long enough to remove excess humidity, leading to moisture problems. Down the road, these issues can turn into mold and mildew growth, affecting the indoor air quality of your facility.

When your HVAC unit is just the right size, it will promote efficiency. In turn, the interior temperature will remain consistent. And your energy costs will be right where they should be.

Factors that Affect HVAC Sizing

To correctly size your HVAC unit, you will need to find out how many British Thermal Units (BTUs) are required. However, discovering the right HVAC system size requires more than just calculating square footage. In fact, HVAC sizing can be affected by any number of factors, including, but not limited to:

• Regional climate
• Siding materials, such as brick, wood or concrete
• R-value of insulation
• Amount of natural light/shade each room receives
• Number of windows and doors
• Usage of lighting and heat-generating appliances

When it comes to your commercial HVAC unit, it’s best to turn to a professional.
