Get matched with top energy efficiency auditors in Marshall, VA

"Edge Energy did an energy audit for us, then sealed the house, installed a new roof with excellent insulation, and an ERV fan to ensure fresh air. They were a delight to work with throughout, very friendly and professional. We needed some follow up work due to quirks in the house, not bad work by Edge, and they did it promptly and without charge. I couldn't recommend them more highly."

"Very satisfied with responsiveness, punctuality and professionalism! Danny was able to squeeze us into Blue Star's full schedule at a time that worked for us and called before the visit for clarification about the problem, and after the visit about how things went. John called before arrival to let us know about exact timing, and was very thorough in investigating the problem and then explaining the situation. After consultation, he was able to repair our system. John also discussed what to look out for in case there are problems in the future. We have had our AC unit serviced regularly by other companies, but we will never use those other companies again. Blue Star is superior in every way! Cannot recommend highly enough. Thank you, Danny and John!!"

"Mohammed handled our project—sealing and insulating our attic. He was very knowledgeable about the best way to accomplish the task in an older home such as ours; and he also ensured that our project qualified for relevant energy rebates. He was professional and courteous in answering all our questions and completed the project in one day. We highly recommend HESS and Mohammed El-Goul."

"Phenomenal job by Evergreen.  Analyzed the current box and gave me options, best, most cost effective was upgrading the 40 yr old CB panel and adding a generator interlock.  Work was done perfectly and efficiently...now when the neighborhood goes dark (all too often when the weather is bad in Northern VA), we have power and AC.  Thanks Evergreen."

"Value Neil Simmoms was timely, courteous and explained everything thoroughly. He found what was broken on the gas fireplace. Ordered the part, came back and installed it. Fireplace is working like new! I highly recommend OHA Heating and Air for all your Heating and Air needs! ALSO, THERE PRICES ARE EXCELLENT!!!!!! Twenty star service from Neil Simmons and the entire OHA Staff that I've dealt with!!! ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️"

"Great Lights uses very little electricity. Thank you 5 Year warrenty."

"Barry is a real professional. Everyone on his team, including office staff and on-site technicians were first class. He came back to check on the results. Would absolutely use them again for any of the services they provide."

"Very personable, Very professional, They went above and beyond the call of duty! Very accommodating. Any questions I had they answered! They were great! Highly Recommended!"

"My furnace is very old and quit working.  I called several HVAC companies and received  quotes to replace ranging from $1,800 to $11,000.  I found Energy Wise on Angies and called Matt.  He returned my call within 30 minutes and was at my house within 24 hours.  After his inspection, he stated that the furnace was still in good shape and could offer me a  number of years service before buying a new unit.  He suggested replacing the motor and fan and cleaning internal parts.  All of this was completed by the end of the next day.
Matt is very professional, punctual, courteous and a pleasure to deal with.  Not only did he save me a great deal of money, I now have a heating/air conditioning system that has never worked better.
