❓ Frequently Asked Questions
Cooling load refers to the amount of heat energy that needs to be removed from a space to maintain comfortable temperature and humidity levels. It’s crucial for sizing HVAC systems correctly – an undersized system won’t cool properly, while an oversized system will cycle on/off frequently, reducing efficiency and comfort.
Our calculator provides professional-grade estimates using industry-standard calculations. It accounts for key factors like room dimensions, insulation, occupancy, and heat-generating equipment. For precise calculations on complex projects, we recommend consulting with an HVAC professional.
Sensible heat relates to temperature change that you can “sense” or measure with a thermometer. Latent heat involves moisture in the air (humidity) and the energy required to condense it. Your AC must handle both types of heat for proper cooling and dehumidification.
One ton of cooling equals 12,000 BTU/hr. Our calculator automatically converts your total cooling load to tons and suggests an appropriately sized unit. Most residential systems range from 1.5 to 5 tons.
The main factors are: room size/volume, insulation quality, number of occupants, window area/sun exposure, heat from appliances/lighting, and outdoor climate conditions. Our calculator accounts for all these variables.
