Customer Reviews

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 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 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.

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.

Shane 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.

Oasis installed a new A/C in our condo and we had a great experience from start to finish. The owner, Mike, came out to provide a cost estimate and was very knowledgeable. I appreciated that Mike recommended a specific A/C solution for our needs, whereas other companies we engaged presented multiple product options with no explanation of the differences. Fernando, Serge and Joe handled the installation and were total pros— punctual, communicative, efficient and tidy. They encountered a setback with the crane and got it handled fast, calling a 2nd crane out to the building in no time. They also identified a problematic piece of piping from a previous install and fixed it on the spot. I’ll definitely be using Oasis for future HVAC needs.
Response from the owner:Thank you, Crystal, for sharing your wonderful experience with us! We're glad to hear that Mike was able to provide you with the right A/C solution and that Fernando, Serge, and Joe delivered a professional installation. We appreciate your trust and look forward to assisting you with any future HVAC needs!

Amer and Steven were great! Super personable and efficient, they fixed an issue with the initial quote fast and then got to work. Knocked out the job in no time and made my day exponentially less stressful. Really appreciated their professionalism and expertise. 10/10, would hire again. Im also about to pull the trigger on a quote from Oasis concerning HVAC work almost entirely based off this experience. Thanks guys!

Joseph and Kwee showed up on time and were very polite. We promptly went to basement where the PVC pipe for my HVAC drainage had snapped in half. Joseph took a look and told me exactly how he was going to fix/replace the broken pipe. I was in a rush because I was on a client call when they arrived (my fault for not checking my calendar). As I ran upstairs, Joseph asked if I wanted to review pricing, which would have slipped my mind had he not stopped me. I’m very grateful he took the initiative to do that. I was surprised at the price of $225 as other companies had quoted me much higher prices. Once that was agreed upon, Joseph and Kwee got to work and were finished in about 20 minutes. The process was seamless and they were careful about being quiet as they were leaving to not disrupt my call. I will definitely be calling Oasis for my next plumbing job. Before and after pics attached. Thank you, guys!
Response from the owner:Thank you, Michelle! We appreciate your kind words about Joseph and Kwee's punctuality and professionalism. It's great to hear that they were able to assist you promptly and efficiently. We look forward to helping you with your next plumbing job!

Oasis Heating and Cooling are definitely the people I recommend for HVAC situations. They’ll be honest with you about what’s going on and what your options are. They may not be the absolute cheapest option but you get what you pay for, and one visit from them compared to multiple visits from someone who is dirt cheap is going to be worth it in the long run.
Response from the owner:Thank you, Spencer! We appreciate your recommendation and are glad to hear that you value our honest approach and the quality of our service. Your support means a lot to us!
