We highly recommend Oasis! The best price! Jerry & Daniel did an excellent job on our installation. They were great at communicating before & during the job. They were also very neat during the job & fully cleaned up afterwards. Thank you!!

The staff at Oasis was quick and responsive. My AC died during a heat wave (so it was 92• in my house). The hot to my house in a day and a half. And not only did they repair my AC unit, but they were willing to help out my neighbor who was also having an issue. Kudos to great service! I will use them again.
The serviceman....Anthony.... was quick (15 minutes to repair) and efficient for my inoperative AC. No surprises such as "you need new ducting, freon, etc" so that was refreshing. And Stanley, phone coordinator, made things easy too.
He stated a time that was honored and the price was very reasonable.
Simple, easy.
On time, professional, knowledgeable. Very satisfied.
They were great to work with, showered genuine interest in obtaining my business and did a great job installing a new heat pump for us.
We just had a very big job done on our home by the team at Oasis including HVAC, furnace, ducting, and exhaust fan installation, and I can tell you that the work ethic, knowledge, and professionalism demonstrated by this team is beyond stellar. Stanley, the owner, was kind and very informative while scheduling my quote appointment over the phone. Chris then came by to provide us with a quote, and demonstrated incredible on the spot knowledge and patience any time I asked him a question. He answered clearly and concisely, while providing helpful feedback and suggestions which was so appreciated. He took care of us and our project until the very end, making himself available via phone to the install team any time questions arose. Then came Jerry and Daniel to carry out the job itself over the span of 3 days. To say that that Jerry and Daniel are all stars at what they do feels like a total understatement. They were incredibly kind, professional, provided us with clear communication throughout the project, and they worked so well together as a team. This was such a demanding and labor intensive job, and yet their work remained consistently meticulous, clean, showed such attention to detail, and went above and beyond what we expected many times and in so many ways - demonstrating the wonderful care they take in the job at hand, and for their customers. Their work ethic is truly unmatched. From my perspective, Jerry and Daniel don't just excel at their job, they've mastered it. I'm so grateful that they were the ones called to work on our home. If you have a similar job that needs to be done in your home, trust me, they are the ones you want on your team as well.
Very good price and excellent service. They replaced my water heater tank in 1hour and half.
Excellent customer service! Great work! Highly recommend!
Great experience overall. The technician was on time, professional, and did a thorough job servicing our AC, including changing the filter, cleaning the outdoor unit, and fixing our condensate drainage. He also took the time to answer all my questions and explain what he was doing. Very knowledgeable and helpful. Would definitely recommend!
