"We had multiple HVAC related issues with our basement renovation and Jacob was able to work within our tight timeline to get it all done. We also discovered some exterior electrical issues that needed to be fixed while they were dealing with our HVAC. How convenient that Jacob is qualified in both areas! His pricing was fair and communication was excellent. I highly recommend DMES for your HVAC and electrical needs. Jacob is a pleasure to work with!"
"DMES installed a new energy efficient HVAC system at my house a few winters ago. The freezing cold of winter is a horrible time to have your HVAC system die. They responded quickly to my emergency, installed a more energy efficient system than what I had, and were so professional. They continue to impress me in how quickly they respond each time I need routine service. I have them on speed dial for all mechanical and electrical projects at my house and I highly recommend them to my neighbors and friends."
"My 38-year-old boiler died last Wednesday night. I called Jake and he came right over. He installed a new Weil Mclain ECO Tec 199C tankless boiler and hot water heater the very next day. I cannot believe how quiet it is. Jake did a great job — his craftsmanship is impeccable. Jake has also done 2 AC units and a hot water heater for me over the years. I've highly recommended him to family and friends and will continue doing so."
