To have a proper HVAC system running at the very optimal efficiency, homeowners as well as business owners alike need to be perfectly well aware of the heat load of the entire building. This is a metric which is measured in tonnage and it is going to determine the size of your entire HVAC system. Selecting the right size is going to prove to be very important when it comes to it as it would determine the efficiency. For instance, if you have an overly-sized unit, it wouldn’t de-humidify the air as well throughout the entire summer. If there is an under-sized system, you might not be able to heat or cool the building effectively.
The most common way to determine the heat load of the entire thing is using a Manual J calculation. This is something that any licensed HVAC contractor could easily do for free. There are a few online calculators that you can take advantage of if you feel like it and it’s important to make sure that you take proper care in doing so.
Materials for Walls, Ceilings and Floors
Now, the heat load calculations are going to take the actual insulation properties of your home. This is the reason for which it’s not going to be enough to know that your home is made of brick. This might not include the insulation. There are different types of insulations that you would need to account for as well. The same principle is also going to apply to the ceilings and the floors.
The overall insulating properties of the windows could also be quite different, based on whether or not it is a single or double-paned window. Even the type of the frame could be of serious importance and it could have an impact.
There are quite a lot of differences in the insulation properties between wood doors of different kinds. As a matter of fact, there are a few different types of wooden doors in the calculation of your heat load. The insulation itself is going to depend on whether or not you have a solid or a hollow door.
The Height of the Windows and Ceilings
This is also something which is going to have an impact on how much air needs to be cooled or warmed. The window height has a definitive impact on the overall calculation of the heat load as well. Of course, there are quite a lot of additional components and specifications that you need to take into account in order to ensure that everything is handled properly. This is something quite considerable and would determine the size of your entire system.
If you are unable to do it on your own, it is best to seek the assistance of a HVAC contractor. They are skilled and experienced at handling host of HVAC related issues.
