HVAC Ventilation

Ventilation is the least expensive and most energy-efficient way to cool buildings. In some cases, natural ventilation will suffice, although it usually needs to be supplemented with fans or other forced ventilation. Homeowners might want to investigate whole-house fans.

A whole house fan is a simple and inexpensive method of cooling a house. The fan draws cool outdoor air inside through open windows and exhausts hot room air through the attic to the outside. The result is excellent ventilation, lower indoor temperatures, and improved evaporative cooling.
