All heating and air conditioning equipment in each Pierce home is designed by a mechanical engineer.  The engineer takes the following factors into consideration to determine which system should be installed to provide the homeowner with a comfortable and efficient air conditioning and heating system:

1.   Orientation of the windows in relation to the solar path at different seasons.

2.   Size and type of windows to determine heat loss and gain of each room.

3.   Cubic feet and square feet of each room to determine the heating and cooling load and air flow to each room.

4.   Correct sizing of the ducts to insure adequate air supply to each room.

5.   Amount and placement of insulation scheduled for the walls and ceiling in each room.

6.   Multiple units are installed to provide flexibility in the regulation of temperature.

7.   Many return air grills are placed throughout the home to provide for effective air handling and to provide the most efficient system for the homeowner.
