Determining the size of your HVAC system for your house is crucial, for ensuring comfort and efficiency. It’s not just about the footage of your home. Also takes into account factors such as the layout, insulation, number of windows and even the climate in which you reside.
Typically HVAC sizing is quantified in BTUs (British Thermal Units) for heating purposes and tons for cooling. Here’s a general guideline to follow;
Square Footage; On average you should aim for around 20 BTUs per foot of living space. For example a 1,000 square foot residence would require a system with 20,000 BTUs.
Climate Region; Depending on whether you live in an warmer area adjustments may need to be made to accommodate heating or cooling requirements.
Insulation and Windows; Enhanced insulation and energy efficient windows can help lower the necessary capacity.
House Design; Factors like ceilings, open layouts and multi level structures can impact the size of HVAC system needed.
The effective way to ascertain the size is, by having a hvac professional conduct a load calculation.
