"I complained twice and they had to come back out twice because they didn't apply the insulation as thick as I paid for. I assume because they were angry about coming back out they covered up two of my vents so I can't attach the pipes to them. I can't even find the ends. I will need to dig the expensive foam out to find them."

"If I could leave zero stars, I would. My solar system has never been up and running properly, and SC Solar has done nothing to help. After paying over $65,000 for a system that is now essentially worthless, I feel completely scammed. All the company needed to do was remove and reinstall the panels after I had my roof replaced. Instead, they left exposed wires, creating a major fire hazard. Their negligence has now led to severe roof leaks and damages that total over $100,000 ? and they still won?t come back to fix the mess they created. SC Solar claims to pride themselves on their work, but in reality, they are fraudulent, unresponsive, and completely unprofessional. I?ve been left with nothing but financial stress, safety concerns, and a broken system. Avoid this company at all costs."

FAQs for energy efficiency auditing projects in Lydia, SC

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.
