How it Works

We are sure you are still asking why is all this subsidized or at no cost?  It's simple.  The electric delivery companies are purchasing the energy savings we have provided you.  (Please see Texas Utilities we Serve to see if we serve your area.)  As a result of these savings, the utilities do not have to invest millions in additional infrastructure like power plants and you reduce your utility bills in the process. 

Diagnostic Testing

Below is the diagnostic testing we do before and after our work.  (See No Cost/Subsidized Services we provide for what work we do to try to save you energy)

  

Building Tightness Test (Blower Door)
A Blower Door Test determines the air infiltration rate of air entering or leaving the building. There are several reasons for establishing the proper building tightness. An appropriately sealed home will:
• Reduce energy consumption due to air leakage
• Diminish potential condensation problems
• Avoid discomfort caused by air leaking in and out of the building

 

 
Duct Efficiency Test (Duct Blower)
A Duct Efficiency Test is performed utilizing a Duct Blower. This device can accurately measure the tightness of the duct system. Duct leakage is directly related to energy waste. The EPA states, “Typical duct systems lose 25% to 40% of the heating and cooling energy put out by the central furnace, heat pump, or air conditioner”. See EPA publication (DOE/EEO109) for additional information. With the knowledge we have today, a properly sealed duct system should have no more than 10% leakage. 

Utility may call to set up an appointment
to inspect our work

The utilities typically call about 10% of the customers we do work for to ensure we are following the guidelines. Other than that we have completed your energy efficiency upgrade and we hope you will notice a reduction in your utility bills and increased comfort in your home.
