"They responded to my home quickly and professionally. The technician was very knowledgeable and candid and saved me unnecessary expenses. They fixed the issue and has our ac back up and running within an hour and made sure everything was clean before they left. Will definitely recommend them."

"The installation process went smoothlt, and there was clear and profesional communication throughout."

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"Thank you for your service I was very happy with the change of the thermostat and maintenance of the boiler, it was very punctual and organized in your work I would recommend it without problem, very good work."

"Extremely satisfied & pleased with the work performed by Elm. Eric, Rob & Jesse were great on the installation – on time, neat, careful to show us the status as they went through the job. Have already recommended Elm to neighbors who expressed interest. Scott was great on the initial review & estimate & Cathy in the office was extremely helpful as well. Thank you to the whole Elm Team!"

"Vinny went way out of his way to go to Montauk to give me an estimate on an air conditioning unit in the downstairs and upstairs. He gave me a great price and kept me informed as to when he was picking up the ductless units and when he was going to install them. He and his son were professional and did a great job."

"Great job - coordinated everything and completed the job timely and professionally for a new boiler and hot water tank install."

"It went very well!! The steam cleaning really gets rid of all the dust, grime and dirt that accumulates over time. It gets into all the nooks and crannies that you would need a toothbrush or toothpick to get clean. I feel like my house has never been this clean, and floors have never been this shiny. I would highly recommend them - extremely professional and takes pride in their work."
