There are a number of factors that affect your energy bill. Other factors include weather, energy rates, the number and kinds of lights, thermostat settings for heating and cooling, the number of loads of laundry, and if you have a pool or hot tub. These improvements could mean more energy efficient appliances, which may cost more now, but the energy saved over the life of the appliance makes it a worthy investment. Another improvement could be becoming more responsible with turning lights off, and keeping your thermostat at a comfortable level. This condition can lead to rot, structural damage, premature paint failure and a variety of health problems.
Ventilation can help control such moisture.
But serious moisture problems can be the result of water seeping into your home through the roof, walls, or foundation. Your home, from the foundation to the roof, should prevent moisture entry, and allow excess moisture to escape. Properly installed insulation keeps your house more comfortable, saves energy and money, and cuts down on noise. Before beginning to insulate, be sure to know the appropriate R-Values for insulation, and be aware of how much insulation to install. Too much moisture in a home can lead to mold, mildew, and other biological growth.
