“We are thrilled with every aspect of our new (propane) heaters, but we are particularly grateful for the responsiveness and professionalism of the DeFosses at every stage. The initial site visit was extremely thorough and informative, yet every time I had a follow-up question (or 10!), Ray responded right away and spent as long as necessary walking me through the workings of the mechanism or the logic of the venting or the rationale for the placement to make sure every concern was addressed. The installation itself was performed expertly, with professionalism, and without delay. Afterward, having taken note of when the propane company was coming to install the tanks and activate the heaters, Ray called the next day to make sure all was in order. Moreover, he had been absolutely right about everything.We are delighted with our new heating system and amazed and grateful for the wonderful customer service.Service: Heating system installation“
“Dan, the technician showed up when he said he would after calling me. He assessed my furnace and determined my motor was shot. He showed me where the squealing noise was generated from and had one in his truck for replacement. He replaced it and was quick, and professional the whole time. He provided me with information on how often to do preventative maintenance and to potentially keep this from happening again. The whole furnace is 4 years old and he was understanding of how costly things like this can be. Two thumbs up for him and the company.“
“Mike and the team at 603 were wonderful to work with. Our home was struck by lightning and they helped us install our new water heater. They were very responsive and communicated in a variety of ways. There were a few hiccups out of 603's control and they went above and beyond to make sure our water heater was installed with the highest of quality! We were appreciative of the extra communication they provided with our insurance company. They sent documents and helped clarify questions that were needed for the appraisal. We will definitely use them again and recommend them to all! ⭐️⭐️⭐️⭐️⭐️Service: Water heater installation“
