"We hired Edge Energy to do a full house remodel (3,000 sq. ft.,two floors, kitchen, living room, dining room, family room, breakfast space, four bedrooms, two full baths and a powder room, laundry room). This is a little outside their normal scope but we really liked the company owner, Jason Dispenza and he set up a favorable pricing schedule that didn't include some of the exorbitant management fees we have seen with other contractors. They started with an energy audit which helped to determine some of the aspects of the systems upgrades we would need. We changed the room configuration on both floors, replaced major systems (water heater, HVAC,electrical, etc.) replaced windows and put in new window openings, installed support beams, replaced the roof, insulation, electrical upgrade and lighting, replaced much of the hardwood flooring, drywall, paint and added a new front entry with a new porch. It was a major job which we lived through for months with the exception of about two weeks when the drywall work was being done. Our living there caused Edge some additional work, but they were considerate of protecting what remained in the house, and making the space as livable as possible. The result is beautiful and we probably have one of the most energy efficient homes in our area of Maryland. The Edge crew was great to work with, very considerate and careful to not disrupt our life more than necessary. Mike Hogan, the project manager was very good to work with, attentive to concerns and very responsive to suggestions. During many weeks we were talking daily. Most subs were very good as well- the HVAC, roofing and drywall guys were great. Our only concerns were with the plumber who delayed the project considerably and the final cost of the project was higher than the estimate we had originally received. I would highly recommend Edge Energy for their work and their customer responsiveness. They are technically highly competent and are very good people to work with."

"Founders Insulation has been the best company I've worked with for this type of project. Brian and his team were professional, efficient, and reasonably priced—especially compared to other quotes I received. I could already notice a difference in my house after the installation was complete. I strongly recommend them to anyone looking to insulate their home or business. You will not be disaapointed. Brian is very kind and easy to work with. I will use their painting and drywall services in the future for my home. Thank you so much for the great work."

"Bluestar was extremely responsive to our initial inquiry. A representative came to our home to discuss our needs and to offer alternatives. We reviewed a range of options and the pros and cons of various models specific to our townhouse. Once we zeroed in on equipment choices, we compared their upfront cost estimate with other vendors' options and found Bluestar's estimate to not only be lower than other comparative quotes, but the equipment grades & ratings were higher, and the available installation date much sooner than anyone else. We chose Bluestar and they followed up right on schedule. The installation crew was top-notch, the equipment was installed very professionally, and everything was thoroughly tested before job completion. Throughout the process the technicians explained what they were doing, how the equipment functioned, what minor modifications they were making to ductwork in the furnace area and why, and they answered every other question we had. There were no "surprise" cost increases due to the actual installation work. They stayed true to their original estimate. We're very pleased with the outcome and would highly recommend Bluestar as a trustworthy HVAC business."

"Summary: The Comfy team did a great job b/c they know what they are doing however, they are not without faults. Work Completed: Full crawlspace escalation and turning a vented attic into an unvented attic by adding CC spray from on the roof deck. Time frame: July 13-17 2020 Results: We are only a month out from the work being completed, so the analysis is on-going but here are the numbers so far. My Aug electricity bill was down 26% in real dollars from July. That reduction is in spite of the fact that Aug had a 31% higher average Cooling Degree Days (base Temp 70F - https://www.degreedays.net/-). In addition, the first week of my Aug billing cycle included this work. Again, this is very early on but that is a promising start. Other benefits include less variability in house temperature. Before I would see a temperature difference of 5 degrees Fahrenheit between my bottom and top floors. Now they are no more than 1.5 degrees apart (the thermostat is on the lowest level). This creates an overall more pleasant living environment. So while Iâ m looking at a return on investment that stretches out past 10 years, during that time itâ ll be a more comfortable home to live in. Challenges: My only complaint is that there doesnâ t seem to be a solid quality control program. To be fair, I have high standards of work quality. Especially when Iâ m paying for it. Comfy clearly understands the science and best practices. Itâ s always a challenge translating that over to the real world, which is messy. With that said I felt like I was the one that had to be pointing out the areas of poor workmanship. It sure would have been nice to feel like that quality control was being done for me. Now for the good news, Comfy is correcting all the issues I have pointed out (scheduled but not all completed). Bottom Line: Comfy has a talented team of people, who know the work. They will do a good job at a fair price. But donâ t let the sleek marketing and science lull you into a false sense of security, make sure you get what you paid for."

"Exactly as expected - PERFECT. I have been using this electrician since I bought my current home 22 years ago. ALWAYS get fast, responsive, great service. I wish every contractor I have used was like Stephen Palmer Electric. Every electrician sent out has been polite, honest, professional (and they get the wiring done right at a very fair price)."

"I called Evergreen Electric and setup an appointment for the next day to perform what I figured would be a couple small jobs and to receive an estimate to run cable into new rooms. The original appointment was delayed because of a power outage on another job, but speaking to Josh on the phone, he was willing to come by as soon as he was finished even though it would have been well into the evening. I told him the following day would work fine and we rescheduled the appointment.
Josh arrived the next day and examined our situation. Our house is nearly 40 years old and it turns out the problems were much deeper than I thought. Josh crawled into the attic and rewired the junction boxes that were not just loose but had previously been wired incorrectly. He also spent well over an hour attempting to diagnose why our breaker was tripping without much of a load on it. He was very thorough in his troubleshooting. He replaced the breaker with a higher amp version and the problem is fixed, but he also indicated there is likely more faulty wiring running through the attic buried under the insulation and someone should come back to assess the entire electrical system.
Josh was very courteous and professional and answered all of my questions. After spending about 2.5 hours with us, I was expecting a large bill. I was very pleased when he told me he would only be billing me for one hour.
About 30 minutes after he left, we noticed that a light in the hallway would not turn off. I called to report it and Evergreen responded immediately. Josh came back right away and fixed the problem. He even replaced the light switch free of charge. It is nice to see a company that stands by its work and acts so quickly when something is wrong.
I would highly recommend Evergreen Electric. They are prompt, thorough, and stand by their work.

FAQs for home energy audit projects in Fairfax Station, VA

To prepare for a home energy audit, begin by preparing your space. Clear any obstructions around the attic, basement, ducts, crawl space, appliances, windows, and doors. Gather all your energy bills from the last year and information on home upgrades if you’ve made any changes. If you’ve previously had an audit done, include that information as well.

Finally, be prepared to discuss any questions or concerns you have. If you’ve noticed a rise in your energy bills, hot or cold areas in your home, or unusual sounds from ducts or appliances, make a list to discuss with your auditor.

How often you should get an energy audit depends on the age and condition of your home. New homes with no issues are recommended to get an audit every five years, while older homes should audit every two to three years. If you’ve noticed any changes to your energy bills or other areas of concern, you should get an audit as soon as possible. It’s also a good idea to conduct an audit if you’ve made changes or upgrades to your home, such as installing a new furnace, windows, or doors.

An energy audit takes three to four hours to complete. Your auditor sets up testing equipment, conducts an exhaustive walk‑through inspection, and performs all required evaluations to identify energy loss points. The audit follows a systematic review that includes visual assessments, mechanical tests, and detailed documentation, resulting in a precise report of improvement recommendations.

You can schedule a home energy audit any time of the year—it all depends on what's convenient for you. That said, timing it right can help you tackle issues before they impact your comfort and bills. If you live in a colder climate and want to avoid high heating costs in the winter, getting an audit in the summer allows you to make improvements before the temperature drops. On the contrary, if hot summers are your concern, a spring audit can help you stay cool and save on air conditioning.

To find a qualified home energy auditor, start by searching for local energy auditors with great reviews and recognized certifications like those from the Building Performance Institute (BPI). These credentials ensure they're qualified and can help you qualify for rebates. Don't hesitate to ask about their audit methods and schedule a consultation to see if they're a good fit for your needs. Doing some research upfront helps you get top-notch service and maximize your energy efficiency.

Once you have your energy audit report, it's time to take action. Review the recommendations and prioritize the upgrades that make the most sense for your home and budget. Reach out to experienced pros to get quotes and discuss how they can help. By making these improvements, you'll boost your home's energy efficiency, lower your utility bills, and enjoy a more comfortable living space.
