McCullough - Your Weatherization Specialists.

Austin Energy Estimates The Average Home Loses 27% of heated or cooled air to leaky ducts.

Our energy conservation professionals use a variety of well-established weatherization measures to block heat gain in homes and buildings during summer months and keep them warmer in winter. Rely on our professional staff to properly weatherize your home! You’ll stay comfortable and save money.

McCullough’s Free Energy Audit looks at:

Attic Insulation

Think of insulation as a blanket that helps to keeps heat from penetrating your home in the summer and helps keep warmth inside during the winter. A home with too little attic insulation will be hot in the summer, cold during the winter and be expensive to heat and cool.The US Department of Energy and Austin Energy recommend that homes in Central Texas have “R-38” insulation level in the attic. A McCullough comfort advisor can tell you how much insulation your home currently has and how much you should add for peak performance and comfort.

Duct System / Air Distribution System

Your air duct system plays a critical role in distributing heated or cooled air throughout your home. Even with the most efficient AC and heating equipment, poorly designed or deteriorated ducts can cause room to room temperature differences, hot or cold spots and significant efficiency losses. Poorly desihned ducts can also affect heating and cooling equipment life and reliability.

Austin Energy estimates that the typical Austin home loses 27% of its heated or cooled air to leaky ducts. Duct leakage can make your home uncomfortable while adding hundreds of dollars to your annual heating and cooling bills.

A McCullough comfort advisor can discuss airflow related comfort issues that may exist in your home and can inspect your ducts. Our comfort advisor can help make your duct system more efficient and your home more comfortable by recommending duct leakage testing and sealing, replacing or adding one or more ducts or even a designing a new duct system that can make your home more comfortable and energy efficient.

Home Air Infiltration

To maintain a proper balance between energy efficiency, comfort and health, the US EPA recommends that the air inside a home change over with outside air about once every two to three hours.

Air changes inside your home are accomplished when air infiltrates your home via cracks, crevices and openings found in all homes. Too much air infiltration and a homeowner may feel drafts and experience high energy bills. Too little air infiltration can leave indoor airfull of indoor air pollutants – from cooking, etc. – feeling humid or stuffy. Austin Energy recommends homes have 0.35 to 0.45 air changes per hour to maintain a healthy, comfortable and energy efficient indoor environment.

McCullough’s comfort advisor may recommend that McCullough’s weatherization technicians perform a Minneapolis Blower Door test to determine how leaky your home is. Technicians can then weather-strip doors, seal plumbing penetrations and seal other air leaks to help make your home more comfortable and energy efficient.

Solar Shading

Solar shading is one of the most effective ways to block heat gain and make your home more comfortable and energy efficient during hot summer months. Trees and other vegetation, exterior awnings, and exterior or interior shades can provide effective shading. One of the most effective ways to block solar heat gain – when trees or other means are not available – is by installing solar screens on exposed windows. Our comfort advisor can show you which windows will benefit most from solar screens. Our solar screens are made from high quality materials to Austin Energy’s specifications. We offer several different frame colors to match your home (mill, white, and bronze). Arch and trapezoid windows can be done for an additional charge.
