How to calculate HVAC tonnage

calculating hvac tonnageIn the modern day and age, air conditioning systems have become an ultimate necessity. That is because long gone are the days when people would just be able to survive with their fans twirling and blowing the minimum amount of air. In today’s age, air conditioning systems have been correlated with attaining peace of mind. That is because the cooler the air which would be blown directly on your face, the greater would be your level of peace. On the other hand, the opposite is also held to be true.

Therefore, when it comes to buying an HVAC system, it is crucial to keep the size in mind. However, this is something which majority of the people forget to take into account, thus resulting in a poor purchase decision. Besides, since this is something which is considered to be a significant investment, it would also not be possible to get it changed anytime soon; you would just have to deal with it.

It is for that reason that so much importance is stressed on calculating the correct amount of HVAC tonnage. In this way, you will be able to determine that the correct size is being chosen.

How to calculate HVAC tonnage

The calculation of HVAC tonnage is indeed pretty simple. That is contrary to the popular misconception that an extended range of complicated calculations would need to be undertaken.

To know the HVAC tonnage, you would simply have to measure the length and breadth of your room. After that, you would have to take the square root of the product and then divide it by ten. In this way, you would be able to get the result within a couple of minutes. It does not get any easier than this!

The problems with choosing a big or small HVAC system

So now that you know how to calculate HVAC tonnage, you can pretty much understand that this is something which you will be able to do on your own. However, the problem persists of people not knowing or accepting the importance of determining the accurate or proper size.

Suppose, if you take a smaller ton air conditioning system for a larger area, it means that it would require more time to cool down the whole place. That would result in more electricity being used up, thus resulting in higher utility bills.

On the other hand, if you install a larger ton HVAC system in a small room, then it would result in an over-supply of cold air. Again, this is also not something which is entirely feasible.

Other factors which need to be considered

The calculation of HVAC tonnage is simple and straightforward at its best but we also recommend using an HVAC Contractor for that. Even other than that, there are other factors which you would need to take into consideration. These are as follows:

  • Whether the room walls are directly exposed to sunlight
  • The average number of people who would be staying in the room
  • The location of the room. In other words, whether the room is located at the top or bottom level of the home
  • The outside temperature during the summer season
  • If the room is located near the kitchen.
