"Carman and his crew did a spectacular job upgrading our old knob and tube panel with 200 amp service. He is punctual and professional, and he stuck by the price he quoted. He showed flexibility when I expanded the job to remove the active knob and tube in the basement and wrapped up both jobs on time. He’s thorough, writing down notes of the work during walkthroughs so as not to miss details. He listened to everything we said we needed and made recommendations. I cannot recommend his services enough, and with all the work required for our home, I will be hiring him for work in the future."

"Russ was very professional and he and his team worked hard to replace our system as quickly as possible. His rate for the job came in thousands of dollars less than the other quotes I got. I would hire this company again for my next plumbing issues."

"The young technicians who came to my home to installed the new thermostat and move it to another wall in my home were polite and conducted themselves professionally in my home and cleaned after themselves. I very appreciated Uri suggestion when he recommended to me another alternative at the initial visit and gave me a few quotes to choose from. So I'm very happy with ER service and I would rehired these two individuals back to my home. I will definitely recommend ER to other people in my life."

"Buck and Wayne installed a mini split heating and cooling system in an attic bedroom/bath. The space was very tight and it took a lot of expertise and creativity on their part to hide all the piping. The outside unit mounted on the back of the house above a porch is a lot more visible than I thought it would be but they did everything they could to make it less intrusive. They arrived before 8 am and had to work outside in some bitter temperatures to install the outdoor unit. At the end of the day, Buck and Wayne took time to made sure that I knew how to operate the unit and that I could call if I had questions. I did a walk-through after they left and the rooms including the attic storage space were spotless. I would highly recommend them for any heating and cooling work you are considering."
