Blower Door Testing - Of all the factors that can rob your home or building of heating and cooling dollars, air leakage is one of the most significant.  Experts estimate that as much as 30% to 40% of the energy required to heat and cool a building is wasted through air leakage.  Air leakage can also make a building uncomfortable to live in and contribute to problems with indoor air quality. 

Our technicians use tool called a blower door to find air leaks in walls, windows, doors, ceilings, floors, attics, and crawl spaces.  A blower door is made up of an adjustable frame, a fabric cover, and  a calibrated fan.  We use this equipment to pull a small amount of vacuum on your home and measure the fan flow and pressure using special gages.  From the information gathered, we know exactly how much air leakage your home has compared to any other in the world tested using this industry standard method. 

One of the real beneifits of blower door testing is the ability to determine how well airsealing work is done by comparing real test results before and after.

Duct Blaster Testing (duct leakage test) – The average duct system can leak as much as 30% of your heating and cooling dollars into unconditioned attics and crawl spaces.  Leaky supply ducts lose conditioned air while leaky return ducts pull in unhealthy air from attics and crawlspaces.  Either way, the result is higher utility bills, uncomfortable and possibly unhealthy living spaces, and even shortened system life because your system has to work harder. 

Our technicians use a tool called a duct blaster to quantify and locate duct leakage problems.  Like the blower door, a duct blaster uses a small calibrated fan that is connected to your home's duct system to either pressurize or depressurize it.  By monitoring the fan flow and pressure, the technician can quickly determine exactly how much the duct system is leaking.

Infrared ScanningInfrared thermography is used to identify invisible trouble spots in your home or building.  One of the unique benefits of infrared thermography is that it can be used to “see through” walls to locate problems with insulation, moisture, and even air leakage.  Alone or when combined with other testing equipment, infrared thermography can help pinpoint problem areas so targeted repairs can be made that are more cost effective and provide the most immediate results.
