Keeping your home cool

Understanding how heat is transferred from the outdoors into your home and from your home to your body is important for understanding the challenge of keeping your home cool. Understanding the processes that help keep your body cool is important in understanding cooling strategies for your home. Heat is transferred to and from objects. Heat transfers from you and your home in three ways : Conduction ­ Radiation ­ Convection.

  • Conduction is heat traveling through a solid material. On hot days, heat is conducted into your home through the roof, walls, and windows. blown in attic insulation, air sealing, and home heating and cooling system upgrades will help reduce that heat conduction.Energy Upgrade California Rebates are available for local citizens to have HVAC Home Improvement Projects performed by our highly trained staff at Klaus&Sons.
  • Radiation is heat traveling in the form of visible and non­visible light. Sunlight is an obvious source of heat for homes. In addition, low­wavelength, non­visible infrared radiation can carry heat directly from warm objects to cooler objects. Infrared radiation is why you can feel the heat of a gas stove top, even from across the room.Infrared radiation will also carry the heat of your walls and ceiling directly to your body causing discomfort. Create a comfortable energy efficient living space by installing a Lennox High Efficiency Heating and Cooling System. Receive Energy Upgrade California Heating and Cooling Rebates Today with an HVAC High Efficiency System Install Today with Klaus And Sons.
  • Convection is another means for the heat from your walls and ceiling to reach you. Hot air naturally rises, carrying heat away from your walls and causing it to circulate throughout your home. As the hot air circulates past your skin you breathe it in and become warm. Homes with a properly sealed-ventilated building envelope enjoy greater comfort combined with increased energy efficiency. Call 909.982.5698 to begin enjoying lower energy bills.


Your body can cool down through three processes ­ convection, radiation, and perspiration. Ventilation enhances all these processes.

Radiation occurs when heat radiates across the space between you and the objects in your home. If objects are warmer than you are, heat will travel toward you. Removing heat through ventilation reduces the temperature of the ceiling, walls, and furnishings. The cooler your surroundings, the more you will radiate heat to the objects, rather than the other way around. Energy Upgrade California offers local citizens incentives for HVAC Home Improvement Projects that reduce energy consumption and make local homes more comfortable.

Perspiration can be uncomfortable, and many people would prefer to stay cool without it. However, during hot weather and physical exercise, perspiration is the body’s powerful cooling mechanism. As moisture leaves your skin pores, it carries a lot of heat with it, cooling your body. If a breeze passes over your skin that moisture evaporates causing you to be even cooler. High Efficiency Heating and Air Conditioning Systems Can Increase You Fall and Summer utility bill costs. Home Upgrade California provides rebates to make high efficiency HVAC Upgrades to your local California Home.

Convection occurs when heat is carried away from your body via moving air. If the surrounding air is cooler than your skin, the air will absorb your heat and rise. As the warmed air rises around you, cooler air moves in to take its place and absorb more of your warmth. The faster this convecting air moves, the cooler you feel.
