Customer Reviews

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.

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.

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 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.

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.

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.
Had to call for service on a Sunday morning when my AC unit stopped working. From the minute Oasis picked up the phone, I felt like I called the right place. Within 15 minutes of giving my info to the call service I had a tech call me and set an appointment for 10am same day Naem was on time and took care of the problem quickly. He also checked the unit on the roof besides a complete inspection of the unit in the condo. He was very professional and courteous. And it was very fair pricing for an emergency call on a weekend. I will not hesitate to use Oasis again if there are future problems. 100% would recommend.
Response from the owner:Thank you so much, Barbara! We never want to leave a client without air, and we are so glad we could come out so quickly. We are happy your problem was resolved so quickly, and us and Naem look forward to assisting you again this Winter!
Chris did a great job of resolving the issue.
Response from the owner:Thank you, Daniel! We're glad to hear that Chris was able to resolve the issue for you. Your feedback is appreciated!

We'd just moved into our new condo when we realized that none of the three toilets were working properly and a shower was backing up. Oasis was able to get us on the schedule quickly and the technician they sent out was great. Chris was super friendly, efficient, knowledgeable, and best of all, left us with three working toilets and a draining shower. The previous owners had caused a variety of problems to the fixtures and plumbing. Chris diagnosed and resolved each mystery issue. He explained everything clearly and the appointment overall took far less time than I expected.
Response from the owner:Thank you, Monica! We appreciate your kind words and are glad to hear that Chris could resolve the plumbing issues efficiently. If you need anything else, feel free to reach out!

Incredible work by the Oasis team on our water heater and AC unit replacement. We found ourselves with an aggressive leak from an old AC unit and coil. We were without AC in the heat of August while hosting guests with young children. Hani was out immediately to get us an assessment and estimate. We were even able to schedule additional work we had been planning to save time/money. The very next morning Michael, Serge, and Nick were able to replace our rooftop AC unit, completely gut, replace, and rebuild our coil casing, and install a brand new water heater. Incredible work, very thorough explanations of work done, and thoughtful accommodations for young children and sleeping babies. Can’t recommend enough. The kids weekend was saved, thanks Oasis!!
Response from the owner:Ryan, thank you for your fantastic review! We’re glad to hear that Hani, Michael, Serge, and Nick were able to help you with the AC and water heater replacement, especially during such a busy time. Your kind words mean a lot to us, and we're thrilled to have made a positive impact on your weekend.

Chris the English Plumber saved the day! Our tankless hot water heater got flooded from severe storms while we were out of town and was not working. We coordinated the appointment remotely, Chris disassembled and repaired the unit, and it was back up and running … on a holiday!
Response from the owner:Thank you, Jason! We're glad Chris could assist you and get your hot water heater up and running, especially during a holiday. Your appreciation means a lot to us!
