"We highly recommend U.S. Energy Solutions...Mom and dad had some unforeseen electrical issues that needed to be fixed in their kitchen due to an inspection review before selling their home. I went to Angie's List put in a request for suggestion and U.S. Energy Solutions got right back to me. We set up and appointment! Electrician was prompt, courteous, professional and friendly. He diagnosed the issue straight away, took the time to show us and explain the problem. His confident approach to the problem was reassuring and was fixed quickly! All the way around a great experience!!"

"They showed up promptly to access the problem and jumped right on the problem and ended up having to replace the whole system and they didn't quit til they repaired the damper system as well. Our HVAC has never worked so good! They could however work on keeping me informed of their arrival times. I had to call them each day they were expected to get an ETA."

"Floyd with Ducts Columbia is now the only company I will use for duct cleaning, sealing vents, & dryer vent cleaning. His level of care and detail completing my project left us feeling like we were taken care of by family. He asked my questions, addressed concerns, and educated me in areas where it was important for ongoing safety and health. If I could rate higher than 5 stars I absolutely would."

"Donovan with IA Services was a dream to work with! Not only was he really quick to schedule, he was willing to work on a mini split unit we were struggling to get serviced. He got everything in working order after thorough testing and is literally our savior with this heat wave. He will definitely be our go-to moving forward!"
