"Mike, Jen and the crew at Diamond Mechanical have been absolute life savers! They were able to diagnose and fix the complicated heating system in my home, and they were super flexible working with the other contractors involved in the project. Most importantly, my heating system now runs line a champ! Thanks so much for all your dedication and excellent results. Greg"
"We had an emergency situation with our boiler/hot water unit. Our three year old system that was installed incorrectly by the previous owners of the home failed and leaking like crazy. Our propane provider had come out to fix the unit three times prior without properly identifying the underlying issue, and then quoted us an astronomical price to replace it. I called Diamond and explained the situation. I was able to send them a picture of our unit and situation, which they were able to identify many key factors of why it failed just from the photos. They quoted me a very fair price and were out the next day to remove the old system and install a new Rinnai system and everything that went with it properly and efficiently. By the end of the day we had heat and hot water back up and running and better than ever. The team was fantastic."
"Mike and his teammate John just replaced my pressure relief valve. They arrived on time, were professional and easy to do busy with. I'll continue to call Diamond Mechanical for all of my heating/AC needs. Thank you!"
"We just had our annual tune-up with Diamond Mech. and I was so impressed with their employee. Extremely nice and conscientious. Explained everything really well. Just a great, genuine person with excellent customer service skills."
"Diamond Mechanical has been super helpful; punctual, professional and always high-quality work. We've used them for installation and maintenance of a new system, and common repairs of an old system. Mike and Jen have both helped after regular office hours trouble shoot problems over the phone with pictures and email. And when needed they've always shown up on time and solved the problem quickly. Highly recommend."
