Frequently Asked Questions

What is cooling load and why is it important? +

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.

How accurate is this cooling load calculator? +

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.

What’s the difference between sensible and latent heat? +

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.

How do I convert BTU/hr to tons of cooling? +

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.

What factors most affect cooling load? +

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.
