"Service was terrible!! Rep came to my house on 11-15, for a power issue in the master bedroom. The rep checked the breaker box, and the load on the line going to the room. He said the load is correct everything looks good, and was told the breaker was bad! The rep then said he was switching the circuit to another circuit, and doing it that way wouldn't cause any issues and wouldn't trip again. The rep said the breaker would need to be changed, and that he didn't have any on the truck. He left, and the breaker tripped the same night. Went to the breaker box, and the same breaker tripped. Reschedule another visit for 11-17, and the same rep. He says it tripped again and I said yes! He then ask to come in the house to check the room! He check one outlet, and says this wouldn't pass code! Then goes and check 3 outlet in the room, and there are a total of 6. He then tells me Choice Home warranty would be getting back to me, because the electrical line coming from the breaker box going to the room is bad, yet 2 days earlier it was fine! I then ask the so-called 10 year pro, how did he come to the conclusion it was the wire coming from the breaker box? I get the dumbest unprofessional response, that he know because he had been doing electrical work for 10 years!! Yes, that may be the case, but I was a technician for 8, and troubleshooting different equipment for 12, and would never have that suspect explanation to explain MY troubleshooting steps! I then tells him that was an unprofessional response, and instead of him backing off he tells me that was a professional response! I then tells him to leave, he then mouths off like a kid, and not a professional! I then tells him if he doesn't leave quick he would have some problems!! He then says you think you big and bad?!! He then goes to his van, and say what you going to do then?! A couple hours later he send a text to my wife saying he hopes the issue gets fixed!! What a joke!! Very unprofessional, and suspect diagnosis!! He second visit was free so I believe he wanted to make some bull up to tell Choice Home warranty. Also, he was complaining about how Choice Home warranty pays him!"

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.
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.
