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

To find a reputable home energy auditor, start by researching local companies that offer the service and check their reviews, methods, and certifications. The most reputable professionals are often Home Energy Professional (HEP)-certified by the Building Performance Institute (BPI). You can also consult the Department of Energy’s certified list of energy auditors or use a state licensing tool to review local guidelines and ensure you are hiring a certified professional for your area.

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

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.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.
