Diversified Energy’s 360 Energy Audit

Other companies’ 10-minute walk-through energy audits simply can’t provide the detailed reporting necessary to provide professional consultations to DE’s exacting standards.

No other local Louisiana company is more qualified to conduct proper combustion appliance zone testing to help keep your family safe from dangerous carbon monoxide poisoning and gas leaks than Diversified Energy. Trust your family’s comfort to our experienced BPI certified home efficiency experts, and call to schedule your 360 Energy Audit today.


Example of Blower Door Testing in a Louisiana Home

Blower Door Testing

This testing quantifies airflow, detects energy loss, and pinpoints air intrusion.

Our analysts use this important diagnostic tool to grade the performance of an existing home about to undergo energy efficiency improvements as well as ensure a tight energy efficient envelope in new construction. We advise new homebuilders to conduct a blower door test after the home is insulated, but before the drywall is hung. Newly enforced building codes have stringent requirements on air infiltration. This test will be able to quantify the results of your home before it is too late—or too costly—to repair the problems.


In a procedure called Blower Door Directed Air Sealing, DE helps to locate and fix leaks in an existing house. Many homes that have been built fairly recently have major issues regarding their inability to be cooled or heated appropriately. The owners report hot or cold spots, in addition to excessive energy bills. Our first step in diagnosing the issues with these homes is the blower door test. For a more detailed and thorough audit, a homeowner may also incorporate duct blaster testing along with an infrared inspection. Of course, the DE 360 Energy Audit offers the most detailed reporting of your home’s energy deficiencies.

Duct Testing using a Duct Blaster

Duct Leakage Testing

DE analysts use a duct blaster to pressurize a building’s ductwork system in order to determine the amount and location of duct leakage.

In addition to quantifying how leaky (or inefficient) a home’s HVAC ductwork is, Diversified Energy’s BPI certified professionals can clean and seal a home’s ductwork as part of a comprehensive service plan to maximize energy efficiency, provide cleaner indoor air quality, and uncover any potential health/safety concerns.

Infrared Thermal Photography

Infrared Photography

Level 1 Thermal / Infrared Thermography

Certified Thermography measures surface temperatures by using infrared images on the film to record the temperature variations of the building’s heat spectrum. These infrared images help us to identify problems in the thermal envelope. Thermal photography is a quality control tool to ensure that insulation has been installed correctly and to detect air leakage in the home’s conditioned envelope and ductwork system. The use of a blower door test and duct blaster test help to quantify how leaky the house and ductwork is, but thermal photography enables us to detect precisely where air leakage occurs so that the ductwork can be properly sealed.

CAZ Testing in Attic

CAZ Testing

CAZ testing is a series of proven checks to systematically assess combustion appliance safety.

These Combustion Appliance Zone (CAZ) tests are designed to ensure that flammable fuels or combustion gases are not intruding into the home’s living spaces. CAZ testing also assures homeowners that their appliances are functioning in a safe and efficient manner. This series of tests is mandatory for your family’s safety and is required by most utility companies for any home with combustion appliances located in conditioned interior living spaces. The series of CAZ tests covers these five categories: gas leak testing, depressurization testing, carbon monoxide testing, spillage testing, and draft testing. Trust our BPI certified home analysts to properly conduct this important test to safeguard your family.

Building Code Compliance

Trust your home’s code compliance testing to DE’s experienced pro analysts.

According to state law, all new residential construction requires 2009 IRC energy code compliance testing, as does all new additions, alterations, renovations and repairs. However, unaltered portions need not comply. Diversified Energy is pleased to work with contractors, builders, and homeowners across the Gulf South to provide accurate, comprehensive assessments according to the latest IRC and IECC mandates. As a certified RESNET energy auditor and holder of three BPI certifications, DE provides all of the necessary official reporting to demonstrate that your projects meet or exceed these standards. Call now to schedule your home analysis. Fees are determined by the size and complexity of the floor plan.
