A 2025 reviewer wrote that other electricians they approached backed away from a failed solar thermal hot-water system, and that Derek Reutter studied it, returned a few weeks later and installed and calibrated a new pump and rooftop thermostat, restoring a working system. A 2025 customer said that after two oil companies and four techs could not cure a furnace hesitation, a service call from Derek had it "running like a Swiss watch." A 2025 customer said Derek came over on a bitter-cold late evening and fixed a furnace that broke down when the outdoor regulator froze. A 2025 customer said Derek helped them replace an old oil furnace with a high-efficiency gas system that significantly reduced their monthly heating costs. That 2025 customer said Derek and Benson arrived on time and explained what they would be doing each day. A 2022 customer said Derek and his sons replaced an 1800s furnace with an oil-burning furnace and hot-water heater combo, tied into the old cast-iron steam radiators and updated their valves, completing the job in the time frame promised. A 2022 customer described a new boiler and water heater in a 100-year-old house and said Derek left the basement cleaner than it had been before he started. A 2025 customer said Derek and Benson replaced their central air and installed a heat pump; when a needed thermostat was not on hand, Derek supplied an alternate and checked in until the right one came in. A 2024 customer described a multi-head mini-split installation at a split-level home. A 2022 customer said the company installed a four-head Mitsubishi mini-split unit. A 2025 customer said Derek explained how the furnace worked, including what the blinking lights meant, without a high-pressure sales pitch.
Reutter Mechanical has done very accurate work on my heating/cooling systems and more. They have always done a neat and orderly job, diagnosed things thoroughly, and priced their work fairly.
Great service, very respectful team.
Reutter Mechanical did a Beautiful boiler install at my house. They were very prompt courteous and very very clean. I am very happy to have gone with this company. Derek and his son Benson were wonderful. I would highly recommend them to anybody looking for Mechanical work on their home. Definitely a five star rating thank you !!!
Derek and Benson were knowledgeable, polite, friendly and courteous when replacing our central air and installing our heat pump. They are efficient as well. When they say they will be there, they are there. There are just not enough positive words to say! We referred them to two of our friends who hired them to replace their heating systems. We needed a certain thermostat that Derek did not have on hand, but he gave us an alternate one and checked in with us until he could get the one we needed came in. I would recommend Reutter Mechanical time and time again! You will be please with their work!
"Our Schuco Solar Thermal Hot-Water System, installed in 2011, had worked perfectly until last Fall (2024), when it failed – presumably due to a fault in its electrical pump and/or rooftop thermostat; these thermal systems, once very much in vogue, but no longer, have become a rare commodity. All electricians and their companies that we approached for repair – many of which advertised both Solar Electric and Thermal as being within their compass – retreated in bafflement when confronted with the job, leaving us in despair. But not Derek Reutter! Alerted to our plight by a chance acquaintance, he showed up, studied the apparatus, its various features and minimal specifications, while admitting that he hadn't worked on Solar Thermal for years. Eventually he left the scene, with assurances that he would return with a solution – and so, a few weeks later, he did! He installed and calibrated a new pump and roof-top thermostat, thereby relieving our intense gloom and frustration and restoring a working system. Thus, we speak of him as our 'Solar Thermal Saviour'!" Virginia & Anthony Macro. February, 2025.
