Energy Audit & Evaluation

The purpose of a home energy evaluation is to minimize air loss in your HVAC system and throughout your home's structure. Air-loss tests utilize state-of-the-art electronics equipment to pressurize and de-pressurize your home in order to identify and repair costly air leaks. Usually, air leaks are hard to detect and can occur in low or no-traffic areas of your home like duct connections buried underneath insulation in the attic, plumbing penetrations underneath the bathroom sinks etc.


In as little as two hours, our team test you entire home, fix areas of immediate concern and discuss additional options for even more energy savings. Our technicians will:

? Prepare your home for air loss detection tests through:
- A thorough walk-around inspection of the home
- Installing portable fan(s) and doorway venting equipment
- Temporarily sealing your HVAC duct system
- Conduct HVAC air loss test to identify potential leaks
- Repair HVAC system for any leaks found
- Conduct a follow-up air loss test to measure improved efficiency

• Implement whole house air infiltration measures by identifying & repairing areas of abnormal air loss, such as:
- Plumbing penetrations
- Exhaust fan penetration
- Lighting fixtures
- Attic access
- And more

  • Attic Insulation

    Insulation is measured in R-values - the higher the R-value, the better your walls and roof will resist the transfer of heat. DOE recommends ranges of R-values based on local heating and cooling costs and climate conditions in different areas of the nation.

    If your attic has enough insulation and your home still feels drafty and cold in the winter or too warm in the summer, chances are you need to add insulation to the exterior walls and crawl space. These are more expensive measures that usually require installation by a contractor, but it may be worth the cost if you live in a very hot or cold climate.

    Although insulation can be made from a variety of materials, it usually comes in four types; each type has different characteristics:

    Also known as blankets, these are flexible products made from mineral fibers, such as fiberglass and rock wool. They are available in widths suited to standard spacing of wall studs and attic or floor joists: 2x4 walls can hold R-13 or R-15 batts; 2x6 walls can have R-19 or R-21 products.

    Usually made of fiberglass, rock wool, or cellulose, it comes in shreds, granules, or nodules. These small particles should be blown into spaces using special pneumatic equipment. The blown-in material conforms readily to building cavities and attics. This type of insulation is well suited for places where it is difficult to install other types of insulation.

    This type of insulation typically is more expensive than fiber-based materials. It is extremely effective in buildings with space limitations and where higher R-values are needed. R-values range from R-4 to R-6.5 per inch of thickness (2.54 cm), which is up to 2 times greater than most other insulating materials of the same thickness.

    Foam-in-place insulation can be blown into walls, on attic surfaces, or under floors to insulate and reduce air leakage. There are two types of foam-in-place insulation: closed-cell and open-cell. Both are typically made with polyurethane. The type of insulation you should choose depends on how you will use it and on your budget. While closed-cell foam has a greater R-value and provides stronger resistance against moisture and air leakage, the material is also much denser and is more expensive to install. Open-cell foam is lighter and less expensive but should not be used below ground level where it could absorb water.

    Insulation Tips

    ? Consider factors such as your climate, building design, and budget when selecting insulation R-values for your home.
    ? Use higher density insulation, such as rigid foam boards, in cathedral ceilings and on exterior walls.
    ? Ventilation plays a large role in providing moisture control and reducing summer cooling bills. Attic vents can be installed along the entire ceiling cavity to help ensure proper airflow from the soffit to the attic to make a home more comfortable and energy efficient. Check with a qualified contractor.
    ? Recessed light fixtures can be a major source of heat loss, but you need to be careful how close you place insulation next to a fixture unless it is marked or designed for direct insulation contact. Check your local building codes for recommendations.
    ? As specified on the product packaging, follow the product instructions on installation and wear the proper protective gear when installing insulation.
    ? Long-Term Savings Tip: One of the most cost-effective ways to make your home more comfortable year-round is to add insulation to your attic.
  • Doe Recommendations

    The map and chart below show the DOE recommendations for your area. State and local codes in some parts of the country may require lower R-values than the DOE recommendations, which are based on cost effectiveness.

    * These recommendations are cost-effective levels of insulation based on the best available information on local fuel and materials costs and weather conditions. Consequently, the levels may differ from current local building codes. In addition, the apparent fragmentation of the recommendations is an artifact of these data and should not be considered absolute minimum requirements.

Radiant Barriers

  • Radiant Barriers are becoming more commonplace and homeowners are starting to realize the effectiveness of radiant barrier compared to the traditional mass insulation solutions.

    Conventional mass fiberglass insulation, no matter how thick, has almost no ability to block radiant heat energy which can account for as much as 93% of summer heat gain and up to 75% of winter heat loss. These products are only designed to slow down conduction heat energy. Mass insulation is only designed to absorb, slow down and transfer radiant energy.

    Radiant barriers work on a proven principle. Heat, like light, travels primarily by radiation, not convection or conduction. Radiant barriers are products having at least one reflective or low emissivity surface. The purest gold, silver and aluminum are the top three reflective materials known to man. Each have a low emissivity rating and reflect from 95% to 99% of the radiant energy that strikes the material surface.

    Radiant barriers have been studied and reviewed by many independent laboratories such as: Tennessee Valley Authority, Texas A&M, Florida Solar Energy Center, Department of Energy, Oak Ridge Laboratory and many other institutions which have proven how well radiant barrier performs and its effectiveness in reducing summer cooling and winter heating loads.

    Types of radiant barriers Radiant barriers are produced in two basic types, each with their own specific benefits. Our technicians are well-trained in each application and can recommend the best solution for your particular needs:
