Heating and Cooling

If your home stays warm or cool is dependent on your HVAC system* and the Building Envelope** (the physical structure) of your home.


Work with what you have



Adjust your Thermostat

Ideal settings for your thermostat in the summer are 78-80 degrees

Consider the use of fans in occupied rooms. However, turn them off when you leave the room. Fans create a cooling effect when the moving air touches your skin, but does not cool down the air in the room.

For example, if you keep your summer temperature setting at 75 degrees, adjusting it to 77 degrees will potentially save you $79 a year.* *savings based on 1500 sq ft 1975 single-family home with a 10 year old Central AC in southern climate.

Ideal settings for your thermostat in the winter are 68-70 degrees

HVAC System (Heating, Ventilating and Air Conditioning system): provides temperature control and air quality control through filtration.

**Building Envelope

Buidling Envelope: the structural barrier between the interior and exterior of a building. It is responsible for maintaining climate control within the interior of a building. It includes: 

  • Roof
  • Bottom floor
  • Exterior doors
  • Windows
  • Exterior walls

The fewer gaps through which air can escape, then the HVAC system doesn't have to work as hard and saves energy.

In addition to sealing up cracks, having insulation in walls and the attic helps prevent the transfer of heat. In summer, insulation keeps the hot air from coming in, and in the winter it keeps the warm air from escaping.
