Customer Reviews

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.

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.

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.

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.

Shane H.

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.

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.

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.

Second time for repair service and Oaisis exceeded expectations again! Tech was courteous & knowledgeable. He took the time to fully explain the current status, and future work needed on our system. Office also made an effort to try to move my appointment sooner- if I had been available. Above and beyond! Communication is excellent via phone and text. Tech was on time, and stayed for an appropriate amount of time once done to ensure the problem was handled.

Y. “Dewey” Du

Scheduled a seasonal AC maintenance service with Oasis using their online tool a couple of days ago. The technician (Joseph) called on the appointment day and showed up even earlier than the scheduled time. Joseph did a quick and good job checking on the unit. He was polite and patient to answer my questions regarding my system and how their maintenance program works. Thanks, Joseph. I will be calling your team again this fall for the furnace maintenance.

Response from the owner:Thank you, Dewey, for taking the time to leave such a wonderful review and for recognizing our team's efforts, from your techs to our office staff! We truly appreciate your trust in us for your HVAC and plumbing needs. Please don't hesitate to reach out for all your needs in the future, no matter how big or small!

I will never call another service. Everything about Oasis is 5 stars. When I called them just to get information about their services and schedule an appointment, the customer service representative was informative and courteous. I also delightfully surprised that they could schedule a 7 AM appointment so I didn’t have to miss any work. On the day of my appointment, Joseph arrived at 7 exactly! He was also courteous, informative, and efficient. He sealed the deal on me being a lifetime customer of Oasis. I highly recommend everyone give this outfit a lot of consideration when deciding who to call. You won’t regret it.
