Spent 5 years learning the craft based on my own interests. Keeps customer completely satisfied. Spend all day thinking about air leakage and how to help those in the Louisiana climate zone. Someone can have the best built home, but if they do not have the correct air sealing, they will be uncomfortable and spend unnecessary money on their energy. My mission is to make my customers the most comfortable in their homes, and save them money.

"He did a very nice job; they are very good and dependable people.  He is very professional and he has an office here at Metairie Road  and he has a cell phone so it is easy to get in touch with him either through the office or the phone.  They did very good work and workmanship was good.  It was kind of delayed to finish it because of the weather outside; he had some other business too, s lot of other customers.  Everything went well and I even had some additional work for him.  I had him do the patio.  He had to take the old patio out and put a new one in plus he took care of the hurricane damage.  He did a good job.  He picked up the patio bill from the refill people. He has two or three workers who actually did all the work.  Price seemed to be reasonable.  As for punctuality we had a lot of bad weather, they had to work around that."

Energy Efficiency Auditing FAQs, answered by experts

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

Audits typically take 2-4 hours, depending on the property size and energy systems.

Homeowners may qualify for an HVAC tax credit if they install an ENERGY STAR®-certified HVAC system that exceeds the energy efficiency minimum standards:

  • Split-System AC: 16 SEER2

  • Packaged AC: 15.2 SEER2 and 11.5 EER2

  • Ducted Split Heat Pump: 15.2 SEER2, 7.8 HSPF2, and 11.7 EER2 

  • Packaged Heat Pump: 15.2 SEER2, 7.2 HSPF2, and 10.6 EER2

  • Mini-Split System: 16 SEER2, 9 HSPF2, and 12 EER2

You can claim up to 30% of the cost of the job, subject to maximums.

The answer is a resounding yes, as dishwashers save significant water and energy compared to washing dishes by hand. The difference is so drastic in fact that those who use energy-efficient dishwashers can expect savings of over $450 per year. This is because dishwashers use less water, they wash at a higher temperature than a hand rinse, and you don’t need to rinse them after washing. New dishwashers use around 4 gallons per load, whereas washing by hand can use up to 2 gallons per minute.

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.
