"We could never recommend. We purchased a 26kw whole home generac generator a couple month back. They set it up and told us to run it 24-25 hours to break it in and they would come change the oil and make sure everything was working fine. At the time of install I was told not to install the app because it was junk. Hours after the tech left we did install the app and after running the remainder of that day of install and throughout the night we manually shut the generator down at 22 hours as we noticed the app was showing the battery was discharging all night and the motor sounded like it was misfiring and had an exhaust leak. The technician came out and found a wire was hooked up wrong and then pulled the spark plug to show me it was fouling out, that wasn?t an exhaust leak, the rocker arms that push the valves down were pretty loose on one side of the engine. He removed the valve cover and tightened the rocker arms down using feeler gauges, yes I watched, and he reused the old valve "

"From the estimate to job completion everything was professional and on time. LHS left my house as clean as they found it. I’ve already noticed a drop in humidity and my Air conditioners are cycling off more often. I placed a thermometer in my attic and there’s close to a 40 degree difference between before and after the spray foam insulation. Job well done."

Comfort Engineered Systems Inc. We go beyond cooling to provide other needs as well. We also specialize in the following: GEO Thermal HVAC Generators Solar Panels Certified Cleaning Program Expert System Air Filtration No matter your needs, from generators to solar panels to geothermal HVAC systems, services, sales, and installing all of the above, we are here to provide the expert work you desire.

"I left a $9,000 deposit with Comfort Engineered Systems over 11 months ago to have a home generator installed. 6 months passed without any follow up by the company. I then placed 15 calls/messages to the company’s voicemail and answering service without ever receiving a single return call. I was finally left with no choice but to physically show up at the company’s office and demand to speak to the owner (Edward Perez). He claimed he never received any of my call and “just by coincidence” I was “next on the list” to have a generator installed. Five more months went by without any contact from the company. I placed another dozen calls to them, none of which were returned. Again, left with no other option I again had to physically show up at the company’s office to get a response as to why I was being completely ignored after having left a $9,000 deposit. When I got to the company’s office it was completely empty although the company’s name was still on the door. Fortunately there was another tenant in the building who informed me that Comfort Engineered had vacated the premises several months earlier and he thought they may have moved to Harrahan. The company’s website still listed the previous address so I had to do some detective work to find the location of their office in Harrahan. I again physically showed up at the company and requested a return of my deposit since over 11 months had passed, I had never received a single communication from the company and they were continuing to ignore my telephone messages. I would like to hand my full deposit returned so that I can move on with my project with someone else. Mr. Perez told me that “we do not return any deposits after 3 days” and again, by coincidence, I was “next on the list”. I told him that if I did not receive a refund of my deposit I was going to pursue legal action and walked out. Mr. Perez ran after me in the parking lot saying he could install my generator next week. Mr. Perez is the most dishonest businessman I have met in 30 years of doing construction/renovation work. Stay away from this guy like the plague."

FAQs for energy efficiency auditing projects in Gretna, LA

An energy audit costs about $420 on average, ranging from $100 to $2,250, depending on the size of your home, property, location, and the tests the auditor needs to perform. Keep in mind that the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit covers up to $150 of home energy audit costs. Common energy audit tests include:

  • Blower door test: $350

  • Duct testing: $100

  • HERS test: $375

  • HERS certification: $200

  • Infrared imaging: $200

The difference between an energy auditor and a home inspector is primarily in the purpose of the inspection. The energy auditor conducts tests in your home to determine the energy efficiency levels in areas like windows, insulation, and doorways. The auditor then makes recommendations for ways to improve a home’s energy efficiency

A home inspector examines various structures of your home to determine that everything is up to code and gauge the condition of features like the roof, foundation, HVAC, and electrical. The home inspector reports on the overall home and makes repair recommendations.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.

To find a reputable energy auditor, find a local company that offers energy audit services. Research the company’s reviews, methods, and certifications to find a reliable professional in your area. The most reputable energy audit companies are HEP-certified by the Building Performance Institute (BPI). Be sure to check our state licensing tool to review the local energy auditor guidelines to ensure you’re hiring a certified professional.
