  I hired 5 Diamond Mechanical for an AC diagnostics as my water source heat pump was not pumping out cold air. They recommended a few services system flush and coil cleaning totaling around $700 or replace the whole unit. Their initial quote for replacement the units guts, as they call them, was $14K which is outrages as I found out from the manufacturer equipment cost is $3995 + tax & shipping. 5 Diamond than lowered their quote to $10K installed which would mean their install labor cost would still be over $5K for a few hours to install a slide in chassis. I unfortunately purchased the services they recommended which did not fix my issue. Why would I trust them with a new install? Let's just say, I will not be recommending 5 Diamond to anyone I know. 👎

  5 Diamond Mechanical was excellent. I live in a high rise and the AC unit was custom designed and built for my building. I called 5 Diamond Mechanical and they were able to send a technician the same day. The technician was very professional, he ran diagnostics on my AC unit and was able to give me options on how to proceed. I knew that what I really needed was a new AC unit since mine was 19 years old. They were able to get one of the custom AC units from the manufacturer, since other homeowners were also replacing their units and the manufacturer makes these in batches. In just a couple of days 5 Diamond Mechanical installed my new unit. They even installed a complementary Nest thermostat. I am very happy with their service and I will definitely recommend them to my neighbors who may need to replace their units. I will also be using their services again in the future for the maintenance of my unit.

  5 Diamond Mechanical was referred to me through my real estate agent. The first thing he told me was that 5 Diamond had exceptional service and a high quality installation process. As I sit at my computer the day after installation was completed, I can confidently say he was absolutely right. I first spoke with Carlos Martinez, co-owner of 5 Diamond, on the phone regarding what system would fit my home. He was incredibly knowledgeable and genuinely easy to talk to. Moving into a new home presents a lot of challenges and Carlos was always responsive and flexible with my crazy hours. Once it came time for installation, there was an initial hiccup regarding placement of the condenser. Once I expressed my displeasure, Carlos and his team worked tirelessly to meet my desires and "knock it out of the park" for me. On day 2 of installation, I met Nick Mullins, the other co-owner of 5 Diamond, as well as his coworker Justin McDonald. These guys had the work ethic of 10 people combined and the knowledge to back it up. They were on time, cordial, and extremely good at their jobs. They took time to walk me through the installation process and make sure they were meeting my expectations. On the final day of installation, they stayed until almost 8 pm to complete the install and walk me through the system and maintenance. 5 Diamond prides themselves on making customers part of their family, and that is absolutely how I felt. I'd recommend them to anyone and everyone. Great job guys!
