Weatherizing your home: Benefits, savings and impact

If your home was built more than three decades ago, chances are it could benefit from weatherizing. The median age for a house in the U.S. is 37 years old, and many older homes do not have the air barriers to protect itself from natural elements.

With a large percentage of energy usage in homes stemming from furnaces, air conditioners and more, weatherizing your home can lead to a significant amount of savings on your energy bill.

What does “weatherizing” mean?

Weatherizing is one of the best ways to protect the interior of your home from wind, rain, and sunlight. What’s more, weatherizing your home increases the energy efficiency of your home.

Weatherizing consists of a process where leaks around the perimeter of a home are sealed along with windows and ductwork. During this process, the added insulation supplements the barrier between the air inside and outside the house and can improve energy efficiency.

Weatherizing your home can include sealing air ducts, bypasses, recessed light fixtures and more.

Read on to learn about some of the benefits of weatherizing your home:

Cost savings

The added insulation and sealing provided by weatherizing can result in savings of more than 30 percent on your current energy bill. This alone can add up to more than $1000 saved annually.

For low income families, these savings can be as high as $400 annually within the first year of weatherizing a home. The cost of weatherizing your home may be offset by the savings it provides each year.

Increased comfort

For homeowners who live in areas with extreme climates or weather changes, weatherizing can stabilize your home’s internal temperature. Frequent and drastic weather fluctuation can cause changing temperatures inside, too.

Weatherizing keeps the outside air from sneaking into your home’s interior, improving your indoor air quality and comfort level. Properly weatherizing your home can keep contaminants such as air pollution and allergens safely sealed off from your home.

Increased lifetime of home equipment

With an insulated and sealed home, equipment like HVACs won’t have to work as hard to keep optimal temperature in your home. By increasing the energy efficiency of these equipment, you can add years of productivity onto its life.

And in terms of cost, optimizing this equipment can save you a lot. It is exponentially more expensive to purchase a new HVAC system than it is to weatherize your home.

Eco-friendly effects

Weatherizing your home can significantly decrease the energy consumption in your home. A weatherized house isn’t just great for saving money – it is also better for the environment. Conserving energy leads to less carbon dioxide and greenhouse gas emissions, which contribute to global warming.

Weatherization assistance programs

Weatherizing your home is not dependent on your income. For families who cannot afford to weatherize their home, the U.S. Department of Energy (DOE) has  weatherization assistance programs in all 50 states.

The DOE helps out over 30,000 families get weatherization assistance annually. Depending on the state you live in, there may be criteria you need to meet to determine eligibility for assistance.

For Texas residents who are elderly, low-income or disabled, there is a Texas Weatherization Assistance Program (WAP). The WAP can cover most if not all the costs of weatherizing your home. Eligibility is determined by a mixture of the number of members in a household, annual pre-tax income and whether there are disabled family members living in a home.
