Best System Design in Anchorage AK

I used Diamond heating when I first bought my house and since then they are the only one I call to clean and inspect my HVAC at my house. Not only they did a good job, they were quick to response and customer service is great. 24 hours after the inspection, I called them to let them know that I can still smell gas in my garage where the boilers at. They sent somebody right away within 30 minutes and the guy inspected it. First thing he assured me that he doesn't smell anything, he continued inspecting and stayed for 15 minutes to air out the garage. I was not charged for this as they call it the follow up inspection. I am happy for being with them for years now.

These guys have been amazing in helping myself and my neighbors with our water leaks and other issues in this continuing wind storm! Very special thanks to Larry, Rob Nelson, and David! On top of their great work, they have also been kind and patient with this clueless single woman! I hope you all get a raise or bonus of some sort; you all deserve it!

Intelligent Design was a recommendation from my realtor, and we will definitely be using them again! They did great work and were professional, friendly, and efficient.

I would highly recommend Paragon to do any of your plumbing and heating needs. They do the job right and will not waste your money and time. There is no need to call any other plumbing and heating companies

Worst experience I’ve ever had! They came to assess my building’s heat issues to give a report of their findings. The agreement was that we would pay for this report. Their team showed up and accessed all of our tenants units. We then never heard back. We finally got in contact with them and they said the building has too many issues and they do not want to work further on it, yet they refuse to give us any notes on what they found, even we we had agreed to pay for it! Terrible service. I will never work with them again.
