Diagnostic Testing

We often accept issues like rooms that are too hot or too cold, unpleasant odors, pests, icicles and ice dams as well as moisture or mold.
The diagnostic tests performed during our home energy audit can help determine the cause of many of the common issues building owners face.
Solutions to these problems are within reach.

Every building is unique. Our building scientist will perform numerous diagnostic tests during the home energy audit to diagnose your building's specific issues. After the energy audit, our customers recieve a report containing all of the information recorded during the home energy audit, as well as a list of improvements to address the problem areas inside your building using a scientific approach specifically designed to resolve your unique challenges.

During the home energy audit, we use building science principles and sensitive scientific equipment to understand any issues within your building. After the energy audit we will provide you with a comprehensive report based on our diagnostic tests and include specific recommendations to resolve the issues unique to your building. Your report includes a variety of energy efficiency improvements - some you may be able to do yourself and others that are more complicated and require an expert to install. No matter how you plan to address improvements, allow us to put you on the path to a more comfortable, healthy, safe, durable and valuable building to enjoy for years to come. If you wish to have us perform some improvements, we can help you to prioritize the work you plan to do in a way that addresses your concerns while being mindful of your budget.

The Tests

Gas Leak Test

Natural gas leaks are very serious, electrical sparks or fire can cause an explosion if there is a natural gas leak in the home. Testing your house for natural gas leaks is one of the important diagnostic tests performed during our home energy audit or home wellness survey.

Blower Door Test

A blower door is a powerful fan that mounts into the frame of an exterior door. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks in the house. Using infrared thermography, our building scientist will determine where your home is losing the most energy. Testing the airtightness of a home using the blower door is one of the most important tests conducted during the home energy audit. The blower door test costs $200 without infrared imaging.

Combustion Analysis

Safety of the heating & hot water systems should be the primary goal of all technicians. The production of carbon monoxide in the flue gases should be kept below 100-ppm inside the flue pipe, and ambient CO should be less than 25 ppm. During the home energy audit, our building scientist will test your heating & cooling sytems for stack temperature, CO2, Efficiency, O2, and CO content. The combustion analysis test costs $35 for heating systems, and $25 for hot water heaters.

Air Quality Test

Most Americans spend 90% of their time indoors. Whether in the home, office or other types of buildings, gas, chemical and other pollutants can cause headaches, eye irritation, allergies and fatigue. Frequent exposure to some pollutants can cause certain types of cancers and other long-term health complications. During the home energy audit or home wellness survey, our building scientist will test your indoor air quality, and generate a report based on your building's unique conditions. The air quality test is free with the home wellness survey.

Inspection with Borescope

Borescopes are used for inspection work where the area to be inspected is inaccessible by other means. During the home energy audit, our building scientist will use the borescope to inspect areas of the home that may be contributing to heat loss, or may contain health & safety hazards. The borescope inspection costs $100.

Mold Test

Mold is found both indoors and outdoors. Mold can enter your home through any opening to the outdoors. Mold in the air can attach itself to apparel, accessories, and pets, which is then carried indoors. Mold grows in places with high moisture content, such as around leaks in roofs, windows, or pipes, or where there has been flooding. Mold grows well on paper products, cardboard, ceiling tiles, and wood products. In 2004 the Institute of Medicine (IOM) found there was sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, cough, and wheezing in otherwise healthy people, and asthma symptoms in people with asthma. The IOM also found evidence linking indoor mold exposure and respiratory illness in otherwise healthy children. During the home energy audit, our building scientist will conduct a mold test in your home. The mold test costs $100.

All of these tests, as well as a scale diagram to calculate square footage, and lighting and appliance inventories to calculate electric load, are conducted during the home energy audit or home wellness survey.

Home Wellness Survey

Did you know that the air inside your home can be worse for you and your family than the air outdoors? With a combined experience of over fifty years, we use our knowledge, expertise, and diagnostic tools to identify where and how your house can endanger your health.

Every Home Wellness Survey Includes

  • Comprehensive Visual Inspection
  • Indoor Air Quality Test
  • Carbon Monoxide Test
  • Formaldehyde Test
  • Gas Leak Test
  • The Home Wellness Survey Costs $75

Building Energy Audit

A Building Audit, also known as a building energy assessment, is the first step to assess how much energy your home consumes and to evaluate what measures you can take to make your home more energy efficient. An assessment will show you problems that may, when corrected, save you significant amounts of money over time. We offer the Building Audit free of charge, which includes appliance and lighting inventories to calculate electric load, a scale diagram to calculate the sq. ft. of your home, an indoor air quality test, a walkthrough of your home to determine insulation levels & condition, infrared thermography using our tablet, photos of the interior & exterior of house for reference, and a building air flow standard calculation. We will provide you with a report containing all of the information we record. We offer additional tests for a thorough analysis of the air leakage and health & safety issues in your home.

Additional Tests Available Include

  • Blower Door Test (w/o IR) $200, (with IR) $250
  • Electric Consumption Test per appliance $20
  • Combustion Analysis (heating system) $35, (hot water heater) $25
  • Inspection With Borescope $100
  • Infrared (IR) Thermography $50
  • Mold Test $100
