We were put on a "short list" because we were without heat, and the process was absolutely seamless thanks to the kind facilitation of representatives Sasha, Samantha, and Adri. We would like to give a special shout out to Dylan and Aiden, the technicians who installed the furnace. These professionals were friendly and knowledgeable, and we feel that they went beyond the call of duty when they descended into the crawl space under our house to repair a torn pipe when it was detected that no warm air was emanating from one of our vents. In closing, thank you, Diamond Heating! We are very happy with our purchase!

Last summer we had a gas line leak outside the house. I called to report smelling gas and they responded immediately sending a tech out within the hour to assess. The tech shut down the lines and instructed me on how to coordinate with the gas company. I really appreciate having this company on our side and highly recommend them. They aren't the cheapest, but their prices are reasonable and fair.

Andrew is an honest HVAC technician and standup human being. I worked in HVAC wholesale for a few…read moreyears and got to know the majority of companies in the area. There are only a handful you can trust, Andrew being one of them. Whether you're doing a new instal or need a repair, you owe it to yourself to get a quote from him. That is if he has any availability haha. I had an issue last year with my A/C. Had a company come out right away and the tech tried to sell me on something that I didn't even need. Finally was able to get AC NW out , and the rest is history. Andrew was able to fix it, without over charging me or upselling me on things I do not need. He's a dying breed in the trades industry. Worth every penny!

My dad ran his own construction firm for years and is a very honest guy. Talking with Andrew reminded me very much of talking with my dad about how to proceed with various projects around my home. He was competitive with the price, and I think it was very fair. I will have him out at servicing time, or if repairs do come up. He is not the biggest company out there, but he is the best. Doing business the way it used to be gives you the information to decide. I knew everything was going to go 100% issue free. From my first contact with him would recommend him to friends and family.

When my Mitsubishi mini-split died, the local guy on the Peninsula really didn't want to deal with it. It was close to 14 years old and he wanted to fix the circuit board for $1,500 Sorry......putting 15 hundred in a rust bucket is never a smart choice. Beach weather is A real bitch folks....be warned....SALT! I decided to replace the unit. In 2025 they banned R410 coolant so, I needed to replace it with R454 and a liquid line and gas line that were THE SAME SIZE, otherwise line replacement for the copper pipes in my house would be $1,800. I found a unit from ACDIRECT.COM made in the USA so no tariffs. The brand is ACIQ and has a 12 year warranty on the compressor and 7 years all parts. YouTube the reviews.......it is a good company and is built in the Carrier plant in Ohio and American owned. Sam came out. I was his apprentice for the day and helped where I could. He is an HVAC expert. He is cautious with promises and I respect that, because people these days EXPECT UNICORNS AND RAINBOWS. This man is legit and I respect him greatly. I am not a bot.
