Pro Tip: Set the Thermostat to Different Settings During the Day

Most homes have an integrated HVAC system, wherein the air conditioning and the heating run through the same air ducts. The inverter is located outside, which in turn is connected to the heating unit. The integration makes it easier to have only one thermostat control.

Depending on the system in place, it is possible to have different temperature controls in different parts of the house. However, the O’Connor Company recommends setting a cost-efficient temperature for the HVAC system.

Factors That Determine Home Temperature

There are several factors that determine a room’s temperature. These include the temperature outdoors, wall insulation, heat produced inside the room, moving air from fans, and relative humidity.

During the daytime, walls serve as a barrier between the sun and the interiors of a house. Sunlight hits the walls and it, in turn, keeps the heat indoors.

At night, the walls radiate the heat out to the cooler air. The amount of heat it disperses inside the house depends on the wall material and room insulation. Other sources of heat insulation are the roof, partitions and windows.

People generate heat from inside the room as well. Opening windows or doors can also allow air outside to enter the room.

Thermostat Control

A single thermostat control allows the owner to set the temperature for the whole house. Temperatures of 77–81°F air conditioning in summer and 64–68°F heating in winter are best for comfort and cost considerations. These are usually the most efficient temperatures for those living in moderate climates.

This range of temperatures allows the HVAC system to work efficiently. Setting the temperature to a year-round 72°F, for instance, makes it work harder, resulting in higher electricity bills. This can also result in HVAC unit breakdowns.

HVAC systems are complex machines that depend on several factors during operation. These machines usually run following thermostat settings. Keeping the thermostat controls within optimal working levels helps lower utility costs.
