Air-Leaks:

Almost all household of United States leaks enough air that can fill up 3-4 Goodyear blimps each hour. All the air leaks through the windows , doors, recessed lights and the attic access are responsible for high energy bills.

Basements:

Hot air generated by boiler raise temperature of your house and into the attic through leakage. This makes a home feel drafty and cause high energy bills. Rim joist air sealing is especially important at bump out areas such as bay windows that hang over the foundation.

Cellar Doors:

Cellar door, also known as, basement door, a bulkhead, a cellar door, or a Bilco door, is main source of moisture in basements. Its responsible for the "stack effect" in your home.

Crawlspaces:

Crawlspaces is an area that homeowners don't visit very often. But this the only area that venture into your home in the form of cold air, moisture, mold, and mildew. IF rim joist is leaky, than it will allow warm air to come inside during the summer causing moisture and cold air in during the winter causing discomfort.

Drafty Windows and Doors:

Windows and doors are inherently deficient in their R-values. A single pane of glass has an R-value of 1, wood doors have an R-value of 2.5, and insulated metal doors have R-values that range from 6-10. The real trouble with windows and doors is not the material used but recklessly they are installed in the framed with rough opening. The gaps that are left around windows,doors and never sealed properly.

Plumbing Penetrations:

If plumbing penetrations which are properly fitted in the existing wall are major cause of exaggerating the stack effect.

Chimney/Flue Chase:

Whenever cavity of Chimney/Flue Chase is heated, the air rises into the attic, turning the shaft into a chimney for the home's conditioned air.

Recessed Lights:

As per US Census Bureau, around 300 million recessed light fixtures have been installed in American homes which caused serious degradation to your home's energy efficiency. The average home has the equivalent of a 2 foot-square hole in the ceiling from recessed lights through which warm air to leak out through the attic.

Attic Access:

Attic access doors/hatches are neither insulated nor air tight. This lack of insulation and air sealing allows heat to escape up into the attic in the winter and brings hot air in during summer.

Dirty Insulation:

Insulation with dark coloration indicates dirt collected by the insulation as air passes through it. Insulation with dark coloration is an indication of air.

Dropped Soffits/Dropped Ceilings:

Generally, builders more focuses on air leakage through windows, doors, and walls. Many of these key areas are hidden from view and are not air sealed or insulated properly.

Missing Insulation:

improperly insulated or completely un-insulated areas of your home cause to cold rooms in winter, hot rooms in the summer, and responisble for extremely high energy bills. The easiest and most cost-effective way to insulate your home is in the attic.

Air Handlers in Attics:

Air handlers installed in attics that typically reach 140 degrees Fahrenheit put a strain on your air conditioning unit are responsible higher electric bills and shorten the life of your equipment.

Heating Systems:

A normal residential heating systems of United States, generally have a heat capacity ranging between 1.5 to 2 times which is larger than that needed to maintain room temperature even on extremely cold days. Due to this over sizing of the heating system, the burner will cycle on and off repeatedly to prevent overheating of the system .

Inductive Motor Loads/Electricity:

Your electric provider sells 3.2 kilowatt hours of energy to use 1 kilowatt-hour in your home. This loss is attributed to the resistance and heat which is generated as electricity travels over transmission lines and into inductive motors in our homes. These motors have coils of copper wire that receive an electrical current to produce an electro-magnetic field to turn the shaft inside the motor.
