	Air Sealing Your Home The shell or outer layer of your home is known as the building envelope. The insulation, outer walls, ceiling, doors, windows and floors work together to control airflow in and out of your home. They also repel moisture and prevent heat from being lost or gained by your home. Most buildings suffer from the effects of poor envelope performance and can lead to high energy bills, drafts, cold floors, humidity or mold, ice build up on the roof or even insect infestation. While replacing windows, caulking and insulation do help with the energy efficiency of your home, these areas are only attributed to approximately 15% of your home’s energy loss. Air sealing improves the building envelope to make your home more comfortable, healthy and energy efficient.		Air Leakage CLICK TO ENLARGE
	Insulation If your home is poorly insulated, it dramatically increases the amount of energy you need for heating and cooling. Energy loss happens through conduction (i.e. heat passing through walls, windows, doors, etc.) and infiltration (air leaking through cracks and gaps). Improving the efficiency of the building "shell" can be one of the fastest and most cost-effective ways to cut energy costs. For a relatively small investment, it is quite possible to increase the comfort of your home while reducing your heating and cooling needs by up to 30%.		Home Insulation CLICK TO ENLARGE
	Duct Sealing Duct improvements that result in a properly sealed system are a wise investment in improving the overall efficiency of your heating and cooling system. Sealed ducts improve your comfort; your health by reducing the air system’s contamination by airborne chemical fumes and other pollutants; your safety by reducing the infiltration of combustion gases, like carbon monoxide, from heaters, gas dryers and other sources; and they save you money through the decreased demand on your heating and cooling system.		Duct Sealing
	Weatherstripping This is also an important component in gaining increases in the energy efficiency of your home. A 1/8-inch air gap along the opening of a pair of 7-foot doors is equivalent to a 10 inch square hole in the wall. Would you leave a window half open during the coldest night of the winter or the hottest day of the summer?
	Home Comfort Inspections Blower Door & Air Tightness Testing Air leakage can increase heating and cooling costs over 30% and contribute to comfort, health and safety problems. Finding hidden air leakage sites, called bypasses, can be difficult without the use of a blower door. This diagnostic equipment uses a fan to pressurize (force air into) or de-pressurize (force air out of) a building. Blower doors have gauges which can measure the relative leakiness of a building.
