A/C Learning Center – Part I

What year and size is the Air Conditioning system?

Let me show you how YOU the Realtor can determine that on your own.  Remember that these dates are NOT installation dates, but they are the manufacture date and typically these dates are close to each other.

First let us understand “Tonnage” is:

Tonnage  The unit of measure used in air conditioning to describe the cooling capacity of a system. One ton of cooling is based on the amount of heat needed to melt one ton (2000 lbs.) of ice in a 24 hour period. One ton of cooling is equal to 12,000 Btu/hr.

This size of an Air Conditioning Unit is based up many factors, such as composition of the building, which way it faces, the number of windows, the amount of insulation…..

Basic Principals of Air Conditioning:

The basic principals of the Air Conditioning System used for Florida.  An AC system is used as a dual purpose.  One is to allow warm air to be pulled into the system, filter this air and then flow across the cold coils and blow cold air into the building.  The other purpose is to pull the humidity out of the air.  This is VERY important.  So with this information – BIGGER IS NOT BETTER!  A house with to large an AC system will always be damp and contain that “bone chilling” cold.  If in doubt call a Professional and licensed Heating, and Air Conditioning (HVAC) contractor.

  How to determine the age and size of the AC unit:

The age or manufacture date of an AC compressor is usually coded under the serial number portion of the data plate that is present on the side of the compressor (Outside AC portion of the AC system)
