What is a HERS Score?
A HERS score is a numerical rating of the energy efficiency of a home. The Home Energy Rating System (HERS) Index was developed by the Residential Energy Services Network (RESNET). It uses an independent third-party to rate residential buildings, and scores are calculated based on factors such as insulation levels, air leakage, window performance, and heating/cooling systems. A lower HERS score indicates greater efficiency—a typical new home has a score of 100; while a home with no energy upgrades would
Why do I need a duct leakage test?
Duct leakage testing is important for several reasons. First, it helps to ensure that your home’s heating and cooling system is operating as efficiently as possible. The ductwork that is full of leaks can cause your system to work harder than necessary, leading to higher energy bills and reduced comfort levels. Second, duct leakage can contribute to poor indoor air quality. Leaks in the ductwork can allow dirt, dust, and other airborne contaminants to enter your home, which can exacerbate
How do I check for air leaks in my house?
How do I check for air leaks in my house? Most people don’t think about checking for air leaks in their homes, but it’s a really important step in determining the energy efficiency of your home. Air leaks can cause many problems, including making your home feel drafty and cold in the winter and hot and stuffy in the summer. They can also increase your energy bills by allowing heat or air conditioning to escape your home. How can I
How long does a HERS test take?
A HERS test, or Home Energy Rating System test, assesses a home’s energy efficiency. The test is performed by a certified HERS rater and takes approximately two to four hours to complete, depending on the size of the home. The first step of the HERS test is to evaluate the home’s energy usage by looking at past utility bills. The rater will then take measurements of the home’s insulation levels and window efficiency. They will also assess the heating and
How does a duct blaster test work?
A duct blaster test is used to determine how much air is leaking from your home’s ductwork. The test uses a device called a duct blower, which is connected to your ductwork and blows air through it. The amount of air that leaks out of the ductwork are measured and used to calculate the leakiness of your ducts. A duct blaster test aims to determine if your home’s ductwork is sealed correctly. If there are leaks in the ductwork, it
Is a Blower Door Test Required in Texas?
It depends. A blower door test can be required certain situations in home building in Texas. The blower door test’s purpose is to determine a building’s airtightness. This information is used to help improve the energy efficiency of the building. The test involves sealing all doors and windows in the building and then using a fan to pressurize or depressurize the interior of the building. The change in pressure is measured, and this information is used to calculate the airtightness
