Thanks so much for taking the time to look into Air Nerds as your last stop in searching for the right HVAC contractor. The owner, James Martin is a 3rd generation HVAC nerd. His father would take him on jobs when he was a kid and tear the work down - making James redo it if it was incorrect. Even in crawl spaces, where no one would see the work. Air Nerds believes in putting ourselves in the shoes of the homeowner who pays the bills. The owner's father taught him the value of honesty and hard work over high-pressure sales and rip-offs. When you choose Air Nerds you can rest assured that our highly skilled team of certified HVAC nerds will enter your home carrying tools and the same principles of business.

"I called James on Monday, he came out, diagnosed and removed the gas valve from my 21 year old furnace. While diagnosing he explained how and why everything worked. He offered to loan me a couple of space heaters for the night. I declined as I had my own. He came back Tuesday with a new valve and I have heat again. He is very knowledgeable, professional, and personable. He takes pride in his work. If I have any HVAC issues in the future Air Nerds will be the first place I call."

"Joshua Walker came to my residence on 10/9/23 for my 2nd A/C maintenance service. I have a posted sign stating regardless of vaccination status, masks are required. I have a disabled and very sickly parent who has immune issues that lives in the home and I specifically stated that a face mask is required. Joshua stated he is not wearing a mask because masks do not work. I stated to him that masks do work and if he is here to do a service in my house a mask is required. I also stated that he either wear a mask or he can not come into my home. He refused to wear a mask and walked away and left. He sent me an email stating I will be getting a refund of 112.50 and as of today 10/18/23, I haven’t been issued my refund. I reached out to inquire about my refund and haven’t heard back."

Inspired Electrical Solutions Inc specializes in the sales, installation and maintenance of generac automatic standby generators for your home or small business, and offers a full range of other services from home additions, to wiring, to electrical inspections and much more.

"The work is still on going but I cannot say enough about Inspired Electrical. Starting with the incredible service from the company's call screener (if that is the right term), Rosie, she put me on the schedule right away. Thomas was the first to my house. He listened intently to my description of the problem and proceeded to test the generator components, all while having B&S Technical support on the line. He diagnosed the issue as the rotor/stator had gone bad (B&S no longer manufactures the item for this model of generator). He then gave me an unofficial quote for for a direct replacement of a more modern B&S generator (direct swap) with a ten (10) year warranty. We also discussed adding my AC to the system. Later I scheduled a formal estimate with Scot. A true gentleman who explained everything step by step, to include looking for ways to get the job done and quoted me a price less than I expected as well as describing for me a future service contract for annual testing and maintenance at an extremely reasonable price. I'm waiting for the order of a new generator to be placed and then to schedule for the work to be completed. I expect this to be just as satisfactory as this review, but Inspired Electrical is my go-to for future generator and electrical issues!"

Loving Air Inc. is a family owned and operated full service heating and air conditioning company servicing the Culpeper, Fredericksburg, King George, Orange, Spotsylvania and Stafford Areas. The company was started in 2014 by owner/operator Shane Loving Master Technician who has been in the trade for over 20 years. He takes pride in helping others and believes that his customers should be 100% satisfied all the time.

"The tech was a nice guy but all I wanted was to fix a blown fuse to get power to my thermostat. I could tell it was company policy to try to make the job as big and expensive as possible and I had to stop him from trying to talk me into a bunch of expensive unnecessary services. That being said they charged $200 just to show up at my door and quoted a total of over $1200 for the simple repair. I felt I had no choice but to pay the exorbitant price because my house was getting hotter by the second. I promise you you’ll be making a big mistake if you let this company in your home."

FAQs for energy efficiency auditing projects in Lignum, VA

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.
