EverGreen Energy Savers specializes in helping homeowners improve the comfort, health and affordability of their home. With numerous tax credits, rebates and financial incentives available for energy audits and energy efficiency improvements, including $150 rebate for energy audits, and up to $1325 for energy upgrades available for DTE/MichCon utility customers, now is a great time to have a professional energy audit for your home.

A typical house is a complex system of mechanical and structural features that must work together to be an energy efficient home. But how do you know where to begin?

EverGreen Energy Savers are certified and experienced building science professionals who will help you know where to start. As an energy audit and performance contracting company, we take a WHOLE-HOUSE approach to help you solve building problems or make the most cost-effective energy efficiency improvements. Here is how…


A good energy audit will give you an honest and unbiased analysis of the areas of your home that need to be improved. A window replacement company is likely to recommend new windows. A furnace contractor will recommend a new furnace. An insulation contractor will recommend more insulation. An independent and objective audit from EverGreen however, will show you where you can get the best return on your home improvement investment.

Depending on the type of audit you select, an assessment of the energy performance of your home by EverGreen may include:

  • a detailed occupant interview and utility bill analysis to identify specific concerns
  • a top to bottom building envelope inspection of the thermal barrier in the attic, walls, basement and other locations
  • blower door testing to locate and measure air leakage and measure natural ventilation or the “tightness” of your
  • state of the art infrared imaging (always in combination with a blower door!) to see air leakage and areas of ineffective or absent insulation
  • an inspection of heating and cooling equipment including testing for combustible gas leaks, carbon monoxide levels, and proper combustion appliance draft and venting
  • Appliances and lighting inspection to identify opportunities for significant savings and improved performance
  • Powerful energy modeling software with improvements analysis showing estimated energy savings and carbon reductions unique to your home
  • An indoor air quality inspection identifying mold and other indoor environmental hazards or concerns
  • A detailed and user friendly report with infrared images, narrative summary of findings and analysis of building performance problems and opportunities, with a prioritized list of cost-effective improvement recommendations.


We provide several types of residential energy audits:

  • Blower door air leakage testing
  • Comprehensive audit
  • Comprehensive audit plus HERS rating

And as a Honeywell Authorized Weatherization Contractor and Performance Contracting company, we can provide all your efficiency upgrades under one roof.

Each EverGreen energy audit provides a clear and unbiased analysis with an action plan for cost saving energy upgrades.

Blower Door Air Leakage Testing

A blower door air leakage and ventilation test is a cost effective approach for finding the source of air leaks that cause uncomfortable drafts, high utility bills and other problems. This test also measures how well your house “breathes” or the natural ventilation rate of your home.

EverGreen Comprehensive Audit

This audit includes a blower door test and infrared thermal scanning, and a home energy survey including detailed report with infrared images displayed clearly within a digital photo, with building envelope improvement recommendations. This audit is perfect for home owners that want a “snap shot” of the homes performance with recommendations for improvements.

EverGreen HERS Rating plus Comprehensive Audit

This audit plus HERS rating includes a blower door test and infrared thermal scanning, and a HERS rating (detailed energy modeling with improvement analysis of building components, i.e. – walls, windows, ceilings, foundation, etc.) including detailed report with recommendations. This audit is a good choice for the homeowner that wants to see clearly which systems of the home are using the most energy, and how much upgrading each system will save in utility bills on an annual basis.

  • I want to thank you for the great job that you did for us. I was able to experience first hand just how much work was involved, and how extensive the project was. If you ever need a commercial reference, please feel free to use Math Reviews.

  • Happy New Year! I just wanted to let you know how pleased we are with the upgrades you did for us at our home. The bathroom fan is amazing! And there is a noticeable difference in temperature between the storage part of the attic and the 'room' part of the attic. So thanks!

    Caitlin L., Ann Arbor
  • EverGreen did a fantastic job retro-fitting our home with the latest energy-saving materials, and sealing the unbelievably many places where heat was flowing out. I had no idea that there were so many ways to tighten and better insulate an old, "leaky" house.

  • No draftiness and the furnace runs less often. Other (my students) notice the music room is very stable in temperature. I especially liked the grouping of improvements and costs so I could figure out what to have done first.

    Jane H, Ann Arbor
  • No evidence of moisture (frost on the wall and floor)...furnace runs less...house retains heat better...Thanks! You may use me as a reference.

  • Hello Nate, Wanted to let you know that my energy usage for mid Feb. - mid March was down from last year for the same period: electric down 34% and gas down 49%. What a difference it made putting in the insulation, changing some lightbulbs, and sealing up the band joists and crawl space.

    DeLynn C, Ann Arbor
  • Hi Nate - Attached below are the electrical and the gas usage comparisons for this house between 2008 and 2009. After Evergreen did the energy conservation work (Feb08), we saw substantial decreases in the gas usage from March 08 and onward...

    David B, Ypsilanti
  • After I had an energy audit by (an insulation company) I added insulation but still noticed a lot of the cold air leaks – Thank you for taking the time to explain to me and show me what was happening (using) your "blower door" – I will be doing air sealing next!"

    Jackie K, Ann Arbor
  • The very first night after (EverGreen) air sealing around our home we noticed such a difference in our daughters' bedroom – what a difference! Thank you!
