HVAC systems are designed to offer both a comfortable and healthy living environment. Aside from giving you the comfort that you need, they also make sure that you are sharing only clean and breathable air with anyone who dwells in your home.
However, in order to fully operate, HVAC systems need to be compatible with the demands of your home. A system that is too small or too big for your home’s load requirement is less efficient in providing comfort and energy savings. To get the most of your HVAC system, you need to discover its load requisites. Learn how you can get the right size system with the correct HVAC load calculations.
Finding the Right Size of System by Load Calculations
Calculating HVAC load requirements needs a professional touch. It requires ample time and strict attention to details. While some contractors depend on rules of thumb to find out the correct system size, others consider all relevant data in the process. These include insulation levels, the home’s layout or orientation, number of rooms, indoor ventilation and many more. The rule of thumb is based on the house’ square footage where 400 – 600 square per ton is used in general calculations. But since houses vary from one another, the load requirement may increase by 25% or more per square foot.
Each house has different cooling and heating needs in BTU per hour, especially at peak conditions. Generally, newly-constructed homes require loads of more or less 800 square feet per ton even during hot seasons. Whereas, well-designed homes need as much as 2000 to 2500 square feet per ton. Thus, if your HVAC contractor uses 500 square feet per ton, you will need a unit that is twice, thrice or 5 times bigger than the standard size.
Oversized HVAC System: Why You Should Not Go For It
Will a bigger system provide better comfort? No, it won’t. Bigger systems can cool or heat your home fast but they can become less efficient in the long run. Aside from being expensive, they are also energy consuming. Too small of systems will not save you money either! They will not be able to provide the level of comfort you need at home. As they constantly run trying to heat or cool down your space, they add cost to your monthly bill without notice.
Choosing the correct size of HVAC system always depends on its load requirements. Anything that is above or below its required capacity is not money and energy wise. You should get the right system size to get the best bang of your investment.
