    Had a wonderful experience with Oasis Heating & Cooling. Installed two A/C Units, one furnace and two thermostats in one day! Very efficient and wonderful to work with. Their communications and attention to detail is fantastic! Highly recommended and would use again for service work! Thank you Mike & Crew!

    I’ve used these guys a couple of times now, one for my home condo and again just recently for my condo that I am renting. They are always professional, and quick in terms of diagnostics and repair. I don’t have others that I can base them off, but I I am not willing to find out since these guys have done a superb job for me. Call them with confidence.

    I called on Sunday at 4PM and they had someone promptly at my place Monday at 7AM. The technician was friendly and resolved my issue quickly and for a reasonable price. I would totally recommend Oasis Heating & Cooling!

    The response time and quality of work with Oasis is top notch. I rent out my unit to tenants and it was very easy to set up billing independently of my tenants while still having Oasis connect with them to schedule and take care of the work. My tenants are happy with the work and response time, and I’m happy with the ease in which I got it all done!

    They did a great job. I called to schedule an appointment. They were here early and fixed both problems that each of my units had. The tech seemed open, honest, and trustworthy and within 30 minutes we had air conditioning again. Would recommend!

    I’ve worked with Oasis on various properties over the last 10 years. The owner, Mike, is attentive and caring. His staff is always top notch and knowledgeable. I honestly couldn’t recommend a service company more than Oasis.

    This place is amazing. I had trouble with our unit (all our fault, long story) but they were so responsive it blew me away. They really made sure we were ok and even said hey, you have small children and its hot we are going to get this done as fast as possible. The tech was just amazing and Mike the owner is as good as it gets. If you are going to have HVAC work done, this is the ONLY place you should consider. Period.

    This is the ONLY HVAC company I will use! They have saved my heat sensitive butt, along with my art and my dog on more than one occasion! They get out as fast as they can, in one case the same day as my house was a roasting 93F, are friendly, caring, efficient, reliable, stand by their work and are experts at what they do. They explain everything and bend over backwards to save you money. I wish all companies operated like Oasis!

    Over the weekend, our thermostat lost power and after several DIY attempts, we decided to reach out to Oasis. We called on Sunday afternoon and they were able to schedule an appointment at 7 am the following morning. They were prompt and efficient. He took the time to explain what he was doing and as he diagnosed our issue. Within an hour, our furnace was up and running. We will definitely be using them again!

    Oasis proved to be as good as all their reviews claim. Asim was the expert technician who came to service our furnace today and he was the ultimate professional, obviously a seasoned expert, and was undoubtedly honest, clear, and efficient with regards to what he was going to do, then did what he said he was going to do, and finally reviewed every detail with me upon completion of his excellent work. I was thoroughly impressed with Oasis and especially Asim’s thoroughness and superb customer service. I would not hesitate to call on them again in a heartbeat!

  • Trang-Huy B.

    I received excellent furnace services from Oasis. We got a service call from Josh of Oasis after we placed the call. It was a cold day and it was a pleasant surprise to get an HVAC service call so quickly. Josh was able to fix the issue very quickly but pointed out that the unit was reaching its end-of-life. A few days later the unit failed and Josh came again to get us going again. This time we agreed that the unit needed to be replaced, and we were able to get a new unit in place very quickly at a very reasonable price.
