Comprehensive Energy Audit
14 Signs That You Need A
Comprehensive Home Energy Analysis
1. High Energy Bills: Don't compare your bills to your neighbors' bills. Their bills may be high for their size home -- and after all, we want to improve your efficiency anyway!
2. Icicles or Damming: Don't blame it on a "bad" winter -- not everyone had the same problems last winter. The "bad" winter just exposed the weaknesses.
3. Drafts: Although the problem may be your windows, don't assume that to be the case. Convective currents (or just improper installation) are usually to blame.
4. Dust: It has to be coming in from somewhere! An improperly sealed home, leaky ducts, and/or an improperly balanced duct system are all potential culprits.
5. Paint Peeling or Blistering: This relates directly to relative humidity in the home. If your home has excessive dryness or humidity, it's a sign of larger issues.
6. Cracks in Walls: Although the blame usually lands on the settlement of the home, expansion and contraction from moisture levels and rotting crawl spaces can also lead to
cracks in the walls.
7. Wide Swings in Temperature: Overcooling or overheating by your HVAC system, followed by long shutoff periods, will cause erratic, uncomfortable temperatures in the home.
8. Temperature Inconsistencies: Having some rooms that are harder to heat or cool indicates problems in insulation, ducts, or the heating and cooling system.
9. Cold Floors: This is usually a sign of problems with insulation, ducts, weaknesses in the thermal and pressure boundaries, and/or an improperly sized HVAC system.
10. Rooms Over Garages: These rooms are generally neglected, with consideration to the envelope of the home. Because of this, they're often riddled with energy issues.
11. Odd or Musty Smells: Musty smells usually mean mold. It doesn't take high concentrations of mold to create odors; microscopic and airborne mold affects your health, and
it's usually the result of energy efficiency issues as well.
12. Mechanical / Chemical Treatment of Other Problems: If you have to run a humidifier or dehumidifier, or you've treated your home for pest issues, you're probably treating
the symptoms and not the source.
13. Dirty Spots Around Registers: This is an indication that condensation is occurring and collecting a higher amount of dirt. This is a good clue that other problems exist.
14. Crawl Spaces: If you have a crawl space, you need an energy analysis for many reasons. Energy loss, mold growth, temperature imbalance, rotting wood… the list goes on
and on. Simply put, there is nothing good about a musty, rotting, drafty crawl space beneath your home.

HVAC Air Flow
Air Handler Flow Meter is designed to provide a simple and accurate measurement of air flow through
residential furance, air conditioners and air handlers. The air flow rate through residential equipment is
an important variable in estimating and optimizing the performance of furnace, heat pumps and air
Air Duct leakage
Duct Blaster is a calibrated air flow measurement system designed to test and document the
airtightness of forced air duct systems. The Duct Blaster fan is connected directly to the duct system in
a house, typically at a central return, or at the air handler cabinet. With the remaining registers and
grilles temporarily taped off, duct airtightness is measured by either pressurizing or depressurizing the
duct system and precisely measuring the fan flow and duct pressure. The average system leaks
Air Flow Balancing
Balometer Capture Hood is the ideal way to measure very low volumetric flow. You can measure
confidently and accurately in testing and balancing of supply and return air in duct system. Accurately
measures CFM and BTU’s delivery of heating and cooling systems.
Blower Door Testing
A diagnostic tool designed to measure the airtightness of buildings and to help locate air leakage sites.
It consists of a calibrated fan for measuring an airflow rate, and a pressure-sensing device to measure
the air pressure created by the fan flow. The combination of pressure and fan-flow measurements are
used to determine the building airtightness. The airtightness of a building is useful knowledge when
trying to increase energy conservation or decrease indoor air pollution, or control building pressures.
Infrared scan used in conjunction with blower door to locate pressure and thermo barriers miss
alignment and Air Infiltration. The ultimate tools for troubleshooting and maintenance. Built for tough
work environments, this high-performance, fully radiometric infrared camera is ideal for troubleshooting
electrical installations, electro-mechanical equipment, process equipment, HVAC/R equipment and

Combustion & Flue Draft Diagnostics
It used to be that gas and oil fired residential furnaces and appliances could be adequately serviced by
conducting visual tests. But with today’s highly efficient equipment designed to comply with regulatory,
environmental and safety concerns, "eye-balling the flame" is no longer a sufficient way to test.
