Do you need a blower door test?

Blower door testing involves measuring the airtightness of a structure. Conducted by an auditor, a blower door test is a diagnostic tool that determines whether there is air leakage in the building. It works by depressurizing the home using a blower door, a powerful fan that pulls air out of the building. Auditors then measure the air that flows into the home through unsealed openings.

What are the benefits of blower door testing?

Here’s why you getting a blower door test is a good idea:

#1 It uncovers structural problems

A blower door test checks for holes, cracks, or openings in your home. Your HVAC technician will be able to address these issues so that you can live comfortably throughout the year.

#2 It reduces your carbon footprint

A blower door test helps you have an energy-efficient home. HVAC systems have to use more energy to maintain comfortable temperatures in a home that’s not airtight. As a result, more carbon dioxide is released into the atmosphere. Conducting a blower door test is one of the first steps to take if you want to go green.

#3 It increases your home’s value

An energy-efficient home is more marketable. A blower door test identifies the investments that need to be made to increase your home’s resale value, such as caulking and sealing air leaks, insulating the attic, and so on. This is because homebuyers want to move into a home that won’t cost them more money in the long run.

#4 It helps you save money

Are your energy bills excessively high? It might be because of air leaks. A blower door test pinpoints problem areas in your home that are causing you to waste energy. Using the results of the blower door test, you’ll be able to apply cost-effective solutions that will save you money in the long run.

When should you get a blower door test?

If you live in California, you are required to get a blower door test to determine your home’s Home Energy Rating System (HERS). The HERS is the standard rating system across the U.S. that is used to evaluate the efficiency of a home. Even if you live in Indiana, or another state, blower door tests are become required more often than not, so it’s always a good idea to get a blower door test to ensure that your home is as efficient and eco-friendly as possible.

Blower door testing should also be done when renovating a home. Contractors and HVAC technicians will refer to the results of the test to make your home more energy-efficient.
