Finding the right size of an HVAC is among the hardest part when planning a new installation for your home. There’s no “one-size-fits-all” method when it comes to proper HVAC sizing.
Here are the three (3) ways on how to size a residential HVAC system:
Use a Formula
Using a formula to size the HVAC system for a specific area of the house is simple. It is important to note, however, that this can only be applicable for measuring the heating load in a particular room. To do this, you need to determine the length and width of the room and multiply them. Then, add the area of the room to get the total. The figure to use should be ‘square meters.’
For example: If your ceiling has a height of 2.4m, then your daytime living space (m²) should be multiplied by 150 watts. For 2.7m ceiling height, multiply it by 160 watts and for 3m by 175 watts. Assuming you have a 100m² daytime living space and the ceiling height is 2.4m, the calculation would be: 100m² x 150 watts = 15,000 watts (15 kilowatts). Therefore, 15 kilowatts is the estimated size of an HVAC needed for your space.
Use an Online Calculator
An online calculator can provide a more accurate estimate than the formula above. When using this method, however, you need to consider a variety of factors, including the room size, the current insulation, the climate, and the number of people living in your home. If you think you can’t deal with the formula or the calculation using an online calculator, then the next method below might be the best and more effective for you.
Use a Professional Calculation from the HVAC Pros
There’s no other method that can offer you the most accurate estimate than professional calculations from an HVAC expert. With their long years of experience and the right set of tools, you can be sure of getting reliable service. You can also receive the proper sizing of the equipment to meet your home’s unique requirements. Professional contractors will consider each factor that can impact your comfort and identify a properly-sized HVAC before the installation begins.
