"Justin called me back immediately & came the same day when my appliances stopped working at the same time. When he identified the motherboard for my range and microwave were fried, he even tried to find replacements on ebay. Unfortunately it didn't work out - but I would highly recommend his services."

"We are extremely satisfied with the experience we had with Dario. Tony gave us a great estimate for a complicated job. He also gave us his honest advice about what to do and not to do. Glad we listened to him. He spent the time to figure out how to make something work even though it didn't look likely. The team was professional and friendly. We will definitely call them back for our future HVAC projects."

"There was a snag at the beginning when they realized, after beginning to dig, that the AC unit was on top of the oil tank and they'd have to call someone in to move it before digging could continue. That delayed things a few days, but thereafter they did a good job of digging and were very careful with our trees. They also took care not to ruin the lawn with the machinery. The new tank and heater were quickly put in the basement with no problems."
