Heating and Cooling System Size

After selecting the best possible type of heating and cooling system for your needs, you should next consider the size of the unit.  Bigger is not always better.

An AC system that is too large may not cool uniformly; may not run long enough to reduce humidity; or may cool an area too quickly, causing the system to cycle on and off frequently.  This wastes resources and increases your energy bill. However, a system that is too small for an area will run non-stop and still not cool the area sufficiently.

To properly size your system, measure the dimensions of the area to be cooled and consider how the area will be used.  Generally, a heating and cooling system needs approximately 20 BTU for each square foot of living space.  For instance, a room that is 15 feet wide by 20 feet long would require 6,000 BTU.  This is calculated like this:  15ft. x 20ft. x 20BTU = 6,000 BTU.

These calculations become more complex when we consider how the living space will be utilized.  Your BTU requirements are increased by how many people live in the home; use of heat producing appliances; amount of glass and exposure direction; humidity levels; etc.  The professionals at Anytime will use these factors to calculate the system size your home would require.
