Everything You Need To Know About Blower Door Testing

As a homeowner in Maine, ensuring your home is energy-efficient is essential, especially during the colder months. If you’re looking for a simple and effective way to achieve this, consider a blower door test. 

This easy, but essential, test determines how airtight your home is and paves the way for energy-saving improvements. In this post, we’ll walk you through everything you need to know about blower door testing and how it can make your home more energy-efficient.

What is a Blower Door Test?

A blower door test is a straightforward procedure that involves putting your home under pressure to detect any air leaks. 

A specialized fan is attached to an exterior door, creating negative pressure inside the house. As a result, outside air flows into the home through any gaps, cracks, openings, or other leaks in the insulation or structure of the house.  

This process helps pinpoint areas of air leakage, ensuring an accurate evaluation of your home’s airtightness.

Why is a Blower Door Test Important?

The significance of a blower door test lies in its ability to boost your home’s energy efficiency. The more airtight your home is by identifying and sealing air leaks, the easier it is to maintain a comfortable indoor temperature and lower energy bills. 

Air leaks can cause your heating and cooling system to work harder, increasing energy consumption and higher utility costs.

When Should You Have a Blower Door Test?

The best time to conduct a blower door test is when your home is easier to evaluate — which is often during construction or remodeling. However, it can be performed at any point after construction is complete to enhance overall energy efficiency.

What Happens After a Blower Door Test?

After a blower door test, you’ll receive a comprehensive report detailing the results and highlights areas of concern. This information will then be used to create an energy model for your home. 

The energy model gives an overview of how the home operates and provides the necessary data to make corrections in the house to make it a more energy-efficient home in the long run.

How Can You Improve Your Home’s Energy Efficiency?

Once the blower door test is complete, the results will guide you on the necessary measures to increase your home’s energy efficiency. This may include adding insulation, sealing gaps or cracks, and upgrading windows or doors. 

These improvements have been proven to save, on average, between 10-30% of the energy consumed before implementation.

A blower door test is a simple yet crucial step for homeowners seeking to improve their home’s energy efficiency. By identifying and addressing air leakage, you can significantly reduce your energy consumption and enjoy a more comfortable living space. 

A blower door test can identify areas for improvement and help implement the necessary changes, resulting in a more energy-efficient home. Ultimately, this investment will pay off in the long run.
