Blower Door Test and Whole House Comfort Checkup

Blower Door Test

  • Do You Have Hot or Cold Spots?
  • Do Family Members Suffer From Allergies or Asthma?
  • Is Your Indoor Air Too Dry or Too Humid?
  • Are Your Utility Bills Too High?

The blower door is a diagnostic tool that can measure and record how badly a building leaks. Department of Energy scientists at Princeton University invented the Infiltrometer™ blower door instrument.  As part of the blower door test, we will pinpoint where your home’s worst air leaks are, and where improvements can be made. This information is compiled and recorded on a laptop and a report is created for you.

A Whole House Comfort Checkup provides a thorough evaluation of all your home’s comfort systems.  As a Comfort Institute member contractor, Boucher Energy Systems, Inc. offers a Whole House Comfort Checkup service.

How does a Whole House Comfort Checkup work?

The checkup starts with an initial interview. Your input provides valuable information, such as whether any rooms feel humid when the air conditioner is running, or if any parts of the house need to be dusted more often than others.

The inspection begins with your heating and cooling equipment. Is it efficient, dependable and safe? We will visually inspect your equipment for any signs of deterioration, improper installation, or insufficient maintenance. We will also evaluate your system’s air filtration and purification efficiency, to determine if improvements would better clean your indoor air.

Even the best heating and cooling system will have trouble keeping you comfortable or will cost more to run if you don’t have enough insulation. We can visually inspect insulation levels throughout your home and determine if they meet currently recommended levels. More importantly, we will look for hidden defects, such as hollow wall cavities, that allow air and heat to bypass your insulation. Attic ventilation levels will also be checked.

Not all air leaks are created equal. From an air quality standpoint, those around your windows and doors are good leaks, since they let in fresh outdoor air. Bad leaks let in dusty, moldy or polluted air from your attic, garage, or crawl space.

If your air duct system has hidden design flaws or blockages, your air flow will be restricted or unevenly distributed. This wastes your money and can make your home uncomfortable. Studies conducted for electric utilities nationwide show that over 66% of heat pumps and air conditioners suffer from this problem.

Do you have rooms that are hard to heat or cool? There are economical solutions. We can use an air flow capture hood to measure precisely how much conditioned air is getting to those rooms (provided the supply vents are accessible). If air flow is low, the causes will be determined, and appropriate solutions will be offered.

Once the inspection and testing are complete, we will explain the results, and give you a prioritized plan of recommended improvements. Many – such as adding insulation or weather-stripping – can be performed by homeowners as weekend projects. Other improvements may require professionals. Upon request, we will prepare a proposal for repairs that we can offer you.
