What is a Load Calculation?
Heating and cooling systems can seem complicated when you are not familiar with the system. There are many terms affiliated with these systems that can be hard to understand. One term that you should learn about, especially when in the market for a new heating and air system is load calculation. This is a very important measurement when purchasing a new system, and it’s something you need to make sure is performed before having a new system installed. This article will explain, what a load calculation is, why it is important, and what the results entail.
What is a load calculation? A load calculation, also known as a heat loss/heat gain analysis, determines the amount of heating and cooling a home may need. Think about it this way, a two bedroom apartment with only one person living in it will most likely not need as much cooling and heating as a three story house, with 6 bedrooms, with 5 people living in it. The load calculation is used to determine the size of your system. For example, the 2 bedroom apartment may only need a 1.5 ton heat pump, and the 6 bedroom home may need a 5 ton system or more.
The way that a load calculation is determined is by many factors. The size of the home is a big indicator, but other factors include:
- Number of windows and window treatments
- Insulation and ductwork
- Building materials and roof construction
- Skylights and fireplaces
- Ceiling heights
- The number of people in your home
- The direction your home faces
A load calculation can be determined only by having a professional visit your home. This is why an estimate for a new heating and air system should not be given over the phone, instead it should be done in your home.
If you do not have a load calculation performed, you could have the wrong sized system installed in your home. If the wrong size system is installed, it can cause many problems such as high energy bills, wear on your system from overworking, may never reach your desired temperature, it may not properly remove moisture out of the air, and many others. All these problems can be avoided by just making sure that whomever installs your new system, is installing the proper sized system.
