Heating & Air Conditioning / HVAC near Brentwood

“The outcome was great. Took too long for outcome to happen. Was not in his control. It was a warranty issue and paperwork was submitted immediately. Took 35 days in the dead of winter to finally get furnaces replaced and running.
Mike was as frustrated as we were. The work Mike did amazing work and once he had everything inline he did it in a timely fashion around Mother Nature. I would recommend diamond mechanical again. He is only one person operation but worth working with. My only issue I had at all was communication during that 35 day period.“

“Ed was excellent and we highly recommend his company. He did a number of projects for us, including installation of an exterior faucet. We're so glad we called him and will do so again.“

“Choosing Oasis was a great decision I made. Their quote was best I had received, (one was almost $4000 more for the same equipment) Jeff was very responsive to any text/ calls within minutes. Jeff has a great team that works with him. Very Efficient and very Neat, you would not know they were even there. They ran Into a couple of issues with the way the old system was installed, but Jeff and crew took it all stride, and made everything right. It could have been a disaster. The difference was night and day. Jeff was very knowledgeable about all the equipment that was going to be used. He answered all of our questions, very thoroughly. Kudos to his team:Ian and Sam also. You will not be disappointed if you choose Oasis for all Heating And Air conditioning needs.

“Matt is very knowledgeable and is willing to work with you to find the best solutions.“

“Highly recommended! From estimate to install of a heat pump in under two weeks. Clear communication, excellent products, and the best price in town. They stand by their work and have the longest warranty/free service follow-up period of anyone we found.“

“DJ was really great! Prompt and knowledgable. We will call him back for future projects.“

“As new homeowners, we have had a lot to learn and Charlie and Joey have been incredibly helpful. They’ve addressed our issues thoroughly and carefully and have answered questions clearly. We’ve also been impressed with how quickly they’ve come out (48 hours at most). Highly recommend!“

“I have been a customer of Nibroc for almost a decade. If you want to understand this company, look at the about page. It’s humble but the truth.

Russ runs what we need these days. Honest company with solid people. He stands by his work. He had to do my furnace and my central air split back in 2017. His crew did an awesome job and we have kept our oil with him since. Reliable and dependable.

He recently had to find a solution for my central air crapping out in the middle of this heat dome (I hate animals, fried the system). Others would have taken me to town, not Russ. He presented me multiple options with pros and cons. The guy is honest to the T and his whole company runs that way. I appreciate what a rarity Russ and Nibroc are in our world now. Show me one other company where the owner shows up at your door to stand by their work? That doesn’t exist anymore.“

“Anthony and his team just replaced both my heating and a/c systems. Professional, efficient, friendly and finished the job ahead of schedule. Would not hesitate to recommend them for any plumbing or HVAC needs. I will have them continue to service my new systems.“

“Our boiler suddenly died during a cold spell, so we were without heat and hot water. We were lucky to find David's Plumbing- they were very responsive to our emergency, The price for replacement was very good, considering that it also included replacing the very old water heater that could have gone at any time and been an extra expense down the road. They were very organized , completed the job in one day. and everyone, from the office to the workers that came to the home were very personable, helpful and professional.“
