When it comes to your HVAC system, there are all sorts of different terms you need to know. One of these is HVAC load calculation. But what does it actually mean? That’s what we are going to explain! Here is everything you need to know about HVAC load and how to calculate it for your home.
What Is HVAC Load?
You need to be sure that any HVAC system you buy can provide sufficient heating and cooling for your house. HVAC load is a term that describes the rate at which a system can remove heat while on the cooling function and warm the air while on the heating function.
This is essential to understand when purchasing an HVAC system as it determines which models will actually work for your home. If you select one with too low of a load, your home will never be comfortable, and if you purchase one with a higher load than needed, you will waste energy. Go into your purchase with the right BTUs in mind.
How Do You Calculate HVAC Load?
How to calculate heat and cooling load is pretty complicated. First, you need to consider the region where you live. Next, you need to know the exact square footage of the home. From there, you factor in ceiling height, the number of windows in the house, insulation grade, sun exposure, the quality of the seals around your windows and doors, and the number of people who live in the house.
This all becomes part of the formula you need to know your desirable HVAC load in BTUs. However, incorporating all of this data verges into complex mathematics. For most homeowners, it is best to keep things simple. The basic formula for calculating HVAC load is as follows.
Square footage x 25
+
Number of people x 400
+
Number of windows x 1,000
+
Number of exterior doors x 1,000
=
The number of BTUs you need
However, it is easier to use online calculators for this. We don’t suggest doing the math yourself even if you have the formula for how to calculate HVAC load.
