Diamond AC and Heating

Never use Diamond AC & Heating. I first contacted them on April 24, 2025, because they were running what looked like an amazing promotion—only $10 for a tune-up, plus you donate canned food to charity. I thought that was such a great idea, so I set it up. When the technician arrived, he told me there was a burnt wire and a part that needed to be replaced. He said it would cost $500, which I couldn’t afford at the time. He then tried to sell me a yearly subscription plan. When I declined, he called his boss, and then came back to me saying they could “help me out” and do the repair for $200. I was grateful, because that was the best I could manage financially. He also told me that the part he was replacing was rare and could only be purchased through an AC company, so I couldn’t go get it

Where was driving this car at 10:28 AM on March 7 needs to not cut people off. This guy cut me off last second otherwise he would’ve been dedicated to go 101 north so instead of just taking the exit. He chose to merge right in front of me almost causing an accident.

Can’t compliment the crew enough! Service was fast and excellent from start to finish! Everyone I dealt with was very professional starting with Caleb who came out and examined my unit. He gave me the information I needed to make the decision to install a new unit. Then the Boss, Cory and Brian arrived on time and the work was done so very conscientiously. Cleaning up as they installed a new thermostat and patching the old holes. And best of all I now have HEAT! And the air does work for this summer. So pleased, Thank you for a wonderful job.

I have searched for a good and honest AC/Heating company for quite a long time to keep up maintenance and to call when needed. As a result, and life happening, my 15 year old unit that still functions well, has been neglected. I came across Diamond and thought I’d give it a try. The man who did my intake over the phone was kind and thorough. Ryan came out to service and explained my 3 main options in detail, knowing I was not ready to purchase a new unit until this one dies. I chose to have the unit overhauled and cleaned up to hopefully get more years out of it, as well as get on a schedule for regular maintenance. Ryan was so kind, thorough, and efficient. I feel confident my unit is taken well care of and I am pleased I can count on Diamond in the future.

My original AC/plumbing/heating company has recently shut down, they’ve been going through high-tech sending inadequate service people. Wasting my days by not showing up or showing up late. I was so pleased that Merlin‘s reached out to diamond HC and heating to pick up their customer services. Their AC/heating inspection was more than adequate. I’ve decided to keep them as my company to service my equipment. Ryan, my tech was polite, asked if he needed slippers for his shoes, explained everything that he was gonna do tweak things that needed to be done and explained the whole situation of services that could be provided. I even signed a one year service agreement for $240 for twice a year inspection for my equipment. I feel I’m back on track with a great company. Thank you. This will be an
