Customer Reviews

Oasis is great! My furnace is almost 30 years old and for a reasonable price they were able to do the repairs. First Danny came to evaluate. He showed me what was wrong. They had to order the necessary parts to fix it. Today Hani and Fernando came to do the repair. They were efficient and courteous. I will definitely use Oasis in the future.

Emily H.

Oasis has always been great to work with and their staff are quick and efficient if issues arise. When our air conditioning broke down during the heat of the summer, they provided a quick replacement at a competitive price. Their staff are always extremely kind, respectful, and knowledgeable.

Sam C.

I called Oasis this morning because my furnace was not working. Within 20 minutes their technician, Danny, arrived. Danny was able to assess the situation, provide an immediate fix, and even commit to returning Monday morning to provide additional services needed. Danny was friendly, informative, professional and FAST! I am thankful I called Oasis for my immediate heating needs and that Danny was the technician who arrived. Top notch service! Highly recommend.

Megan R.

Oasis was incredibly responsive and efficient! My call to them on a Friday night during a cold spell was returned within 10 minutes and he scheduled a tech to come to my home at 7 the following morning. At 7 the tech was there, examined my furnace confirming that a new motor was necessary. He searched for the part, sent a quote and returned with the motor by noon the same day to install it. You can’t beat that!!! I will be using Oasis for all my future furnace and A/C needs.

Gayle V.

The folks with Oasis showed up right on time and replaced my entire furnace and condenser in about 4.5 hours. I had just redone my laundry room where the furnace is and they took great care not to damage anything. Overall very happy with the service and very happy with how respectful the installers were.

Josh D.

Danny and the folks at Oasis got us a great deal on a new furnace and AC. The install took about 4 hours, and they were also super responsive throughout the process. It was about as good of an experience I’ve had with an HVAC company. I’d highly recommend!

Brian C.

I have been using Oasis since 2019. They are reliable, efficient, and their prices are reasonable. The customer service is amazing. Every tech I’ve had come out is knowledgeable, friendly, and professional. The owner, Mike, is hands on and works with you every step of the way. Highly recommend Oasis.
Services include: furnace and AC replacement; annual maintenance.

Nicole U.

I had a great experience with Oasis. Our furnace had issues on Thursday night and Oasis came at 7am the next morning, and we found out we needed a new one. They provided all the necessary information to our condo building so we could get an emergency replacement on Saturday morning. Within 36 hours we had a brand new furnace and the installation team did a great job communicating on their work and how to use the furnace. The owner, Mike, and his team are great and I really appreciated the attention they gave to this matter. I would highly recommend and will only go to them in the future.

Prompt and pleasant service. Highly recommend. 2026 Update: Just had my 20 tr old AC unit serviced by Joseph from Oasis. He was prompt and polite. He explained everything he was doing. Very happy with this company and strongly recommend them. My update for my fall service call is exactly the same as above except that he was able to come early and I was very happy to accommodate him! Excellent!

Service is always top-notch, on time, knowledgeable, and open to questions when needed. I enjoy having Naem come. He knows what he is doing and is familiar with my furnace and with the air-conditioner as well. He is a pleasure to interact with when he comes. It is easy to see that he enjoys his work and is a great representative for Oasis both professionally and personally.

Hani was communicative & polite, asking if he could show up a bit earlier (how often does that happen with service calls?). He was friendly, professional, respectful of my home, & patient with my questions. He also knew what I wanted - to have the fan not running as loudly - without me even asking. I’m requesting him for future HVAC service calls with Oasis!
Response from the owner:Thank you, F! We're glad to hear that Hani provided such excellent service. His professionalism and attentiveness truly make a difference, and we're happy you want to request him for future HVAC service calls. We appreciate your feedback!

Joseph/Quy/Oasis did a great job explaining what was happening w/my furnace. Joseph covered how the system should work and what was going wrong. He very patiently answered all of my questions. The part was ordered and installed the next day. Quy was quick with the installation and very thorough. Could not have asked for better techs!
Response from the owner:Kylie, thank you for your wonderful feedback! We're glad Joseph and Quy could provide you with such thorough explanations and prompt service. Your satisfaction means a lot to us!

Oasis is an outstanding HVAC contractor. We've used them for our home since 2015 and they always offer quick, reliable service. On their recent AC spring maintenance call at our 2-flat they identified that both of our 13-year-old water heaters are were leaking and in need of replacement, as was one of our AC units. They scheduled the work in less than a week and did the 3 jobs in about 5 hours from beginning to end. We received a good price and the work was well done. We highly recommend Oasis!
Response from the owner:Thank you, Martin, for your wonderful review! We're grateful for your continued trust in Oasis and are glad to hear you’re pleased with our service and the recent furnace upgrade. It's been a pleasure to work with you throughout the years!
