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.

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.

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.

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 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.

Oasis is the best. We’ve been working with them for years. Recently had a furnace need to be replaced, and Fernando and Mark went way above and beyond. There were a number of complications throughout the process, and they stuck it out, figured out the problems, and did the work for the amount outlined in the estimate. They will be my first and only call for future work!

Response from the owner:Thank you, Brandon! We truly appreciate your loyalty and are glad to hear that Fernando and Mark provided exceptional service during your furnace replacement. Your trust in us means a lot, and we look forward to being your go-to for any future needs!

Update on April 2026: had my second appointment with Joseph, who was absolutely amazing. I can always learn something useful from him to better care for my system. Highly recommend him and Oasis!

Glad I found Oasis to help me maintain my home heating and cooling system! From booking the first visit, to communicating the arrival time, Chris went up and above. My technician Joseph showed up on time and answered all my questions regarding my home furnace and humidifier. Will be working with them annually moving forward!

Response from the owner:Thank you, George! We're grateful you chose Oasis for your home heating and cooling needs. It's great to hear Chris and Joseph provided such excellent service, and we look forward to working with you annually!

I had worked with Chris and the team a few months ago when my furnace stopped working and had a positive experience, so I reached out to them for what I thought was proactive maintenance on my AC. Turns out the whole thing had to be replaced (makes sense, it was very old). Naim(?) was super patient and kind with me as I asked a ton of questions to understand the situation - he had the same amount of patience when he came out to assess my broken furnace too!

Damir and team who came out to replace my AC were super kind as well, doing the job efficiently and even offered to help move my stuff back into the hallway after they were done.

Something that stood out to me about this process was the customer service - throughout the process, Mike kept me updated on scheduling, and the whole team overall were great to work with. I'm glad I found a reliable team for my HVAC needs moving forward!

Response from the owner:Thank you, Hollina! We're so glad to hear you had a positive experience with Chris, Naim, Damir, and the entire team. Your appreciation for our customer service means a lot to us, and we're here for all your HVAC needs in the future!

Oasis is a great company with great staff. They are American Standard / Trane authorized dealer experts. Joseph, Chris, Michael and Natalia helped me and were very thorough and communicative and gave me top recommendations for my specific unit and situation.

I had a furnace installed by another company and the process was an absolute nightmare. Installation had several errors and issues that my previous company would not address. Oasis identified those problems and rectified all of them. They were able to explain how the system works to me and provide best steps forward.

I will only be using Oasis going forward. Highly recommend.

Response from the owner:Thank you, Luke! We're glad to hear about your positive experience with our team. Joseph, Chris, Michael, and Natalia truly appreciate your kind words. We're committed to providing the best service possible and are happy to have earned your trust for the future.

Danny came out to our home to check out our a/c ahead of summer time, and it turns out it needs attention. He arrived on time, was kind and thorough. He explained our options and pricing. I’ve used Oasis before and found the company to be very fair and professional. I plan on calling them in the future, and I would definitely recommend to any of my neighbors.

Response from the owner:Thank you, Belinda, for your wonderful feedback! We're glad to hear that Danny provided you with thorough and professional service.

We had Oasis install mini splits in our 118 year old home. We received a very fair price, good communication and swift installation/scheduling. They brought a ton of crew members and completed a two day job in one day. They were very courteous to make sure they were wearing boot covers and also cleaned up as best they could before leaving. They consulted me about every decision so the outcome was exactly what I wanted. I highly recommend Oasis, I am a customer for life now - all things plumbing, heating and cooling!

Response from the owner:Thank you, Haley! We're so glad to hear you had a great experience with our team during the installation of your mini splits. We appreciate your kind words about our communication and the care our crew took. Your recommendation means a lot to us, and we look forward to serving you for all your plumbing, heating, and cooling needs!

Would give more stars if they were available! The Amirs - a great father/son team- arrived on time and were finished in the estimated time. They are perfectionists and left me with a new H/VAC system that is better sized to my needs and the American Standard brand is made in the USA. Oasis is neither the highest nor the lowest priced but quality for price is ... priceless. You won't be disappointed if you call them.

Response from the owner:Thank you, Asclepias! We appreciate your kind words and are glad to hear that you had a great experience with the Amir team. Your satisfaction means a lot to us, and we're delighted you found value in our services.

Joseph came out to diagnose a boiler line leak. He provided options to "cap" the line vs replacing the entire pipe. The work involved cutting the dry wall and I was relieved to see that he didn't need to cut as much drywall as expected...I may not even replace it. Really appreciate the professionalism and the cleanup after his work was done.
