    "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."

    "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."

    "First the work area was set up to keep it clean. There were 2 project to be done. The lower part of the porch overhang posts were suffering from water rot. New water resistant material was used. It also improved its look. Then the wood storm frame needed to be fixed and the new storm door was adjusted to fit the opening. All was done in 6 hours. The CRX handyman was able to clearly tell me what will be done. Worked as quietly as possible. We are very pleased with the work the professional handyman and the communication we had with CRM handyman."
