Delivering Warm Air In Winter And Cool Air In Summer

The HVAC system used for residential purposes differs greatly from

those used for commercial purposes. Residential systems tend to be more

furnace focused, while commercial systems are more air conditioning focused. Residential systems are used to maintain the indoor environmental comfort of a house or apartment. Residential HVAC systems are designed to deliver warm air in the winter and cool air in the summer.

This is accomplished through a home unit furnace and air conditioner sharing a common set of ductwork, which is controlled by one central thermostat. The home thermostat is designed to detect when indoor temperatures have risen above or fallen below the preset desired temperature. The thermostat communicates with either the furnace or air conditioner to adjust and provide the necessary warm or cool air to bring the indoor heat back into the desired range.

It is important to note that residential HVAC thermostats usually only measure the temperature in the immediate area around the central thermostat control unit, and therefore cannot measure variable temperatures in other areas of the house. This means that rooms or areas of the house with poor insulation or with higher concentrations of sunlight may have different temperatures than those measured around the central unit.


Clear obstructions like tables and furniture away from vents to maximize the flow of air throughout the room.
