"I had a problem with my AC and called them for a service appointment. John Wayne has a good reputation, so I chose to call them and they were quick to respond. The tech who came to my residence was very friendly and professional, however, he seemed more like a sales rep than a technician. After a few hours and $950 worth of work, he indicated that the HVAC system was not repairable. He created a quote for various options to install a new system. I had previously researched average costs for replacement of a 5 ton / 16 SEER system, which averaged approximately $9-10K for a reputable company with reliable brands. The first option the tech provided was for $40,600, which was a little surprising. He offered several options, with the cheapest being $10,700 for the lowest quality equipment and least warranty. He indicated that the primary difference between John Wayne and other companies is the quality and training of the employees. He also used typical sales techniques, such as “why would you feel different tomorrow” when I indicated that I’d prefer to think about the decisive overnight. During research online, I saw that John Wayne uses Amana products, which are a little more expensive but highly rated and manufactured here in Texas. I purchased a system one echelon higher than the lowest priced system for $13,700, still well-above what I was prepare to pay; however, the tech indicated that they would waive the outstanding $950 bill if I purchased the system and they would be able to install the next day. The next morning, four techs arrived, all pleasant and professional; however, only one appeared to be a trained technician, while the other three appeared to be labor for assisting and conducting menial tasks, such as cleaning the ducts. Within the first hour, two of them accidentally shattered several sconces on the chandelier in my dining room when a piece of equipment fell while cleaning a duct. They are still here in my house installing, but I truly feel like paid too much. Again, I don’t doubt that they are a solid company, but feel like was pressed by a salesman rather than a technician when I needed an urgent problem addressed. I believe I could’ve purchased just as good of a system, maybe better, from a reliable company for a few thousand dollars less."

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.
