We are a full service Air Conditioning and Heating Company. As we prove, "If we can't fix it, it can't be fixed!". We also offer regular rates all day long, this means NO OVERTIME (EVER)! However, we can only work on your air conditioner during the daylight hours. Now your furnace is different though. We can work on your furnace in the middle of the night in case of an emergency or frigid temperatures. Although we can fix just about everything, we also install both cooling and heating equipment. With over 20 years experience, no overtime, the best warranty in town, and the least expensive prices in town, why call anyone else? We also do hot water tank repair and replacement. Angie's List Members receive a $49 diagnostic and 10% off the repair with paid invoice onsite on repairs only. (Cannot combine with Senior Discount 10% on repairs only) http://www.cool225.com

"From the estimate to job completion everything was professional and on time. LHS left my house as clean as they found it.

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."

"I've been with Posigen for about 7 years now and have always paid my bills on time!!!! As of Feb. 2022, I haven't been able to monitor my Solar Production because Posigen haven't updated their system to 5g Capability!!! I told them my payments are to be deferred until they update the system on their end!!! I spoke with a couple Reps that said your panels are producing what they should based on your production on your Electric Bill!!! I asked how can I know if I cant see the daily production to ensure the panels are producing what they should!!! They said take my word for it!!! I'm like that's very bogus to tell a faithful customer to take your word!!! Especially when the issue is not on their end!!! Now because of Non-Payments for 2 months of me not knowing what I'm producing since Feb, they're now threatening to shut my system off!!! Who treats a customer like this when the issue is on their end!!! Especially when that customer has been making faithful payments up into them not upgrading the system on their end!!! Can someone please recommend A good lawyer to stop them from interfering with system!!! Again, the issue is not on my end!!! I need help!!!!"

FAQs for energy efficiency auditing projects in Killian, 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.
