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.

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 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 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.

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 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.

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.

Teresa Uemura

Our air conditioner was not working well and making odd noises, so we had Oasis check it out. After discussing, we decided to replace our ancient heater and aging air conditioner instead of fixing. Oasis sent out Fernando, Joel, Amir and Jose the next day! They were on time, super nice & organized and kept me updated on their work. I thought I would be hanging out all day and have a mess to attend to after, but they were done in 5 hrs and left my condo spotless. We’ve been using Oasis for years as they never disappoint. I would definitely recommend them for your HVAC needs, especially this team.

Response from the owner:Thank you, Teresa! We appreciate your kind words about Fernando, Joel, Amir, and Jose. It's great to hear that they provided timely and organized service while keeping your place clean. Your continued trust in Oasis means a lot to us!

I recently had Oasis Heating and Cooling install my new HVAC system, and the entire experience was outstanding from start to finish. The team showed up right on time and was friendly, courteous, and professional throughout the whole process. They clearly explained what they were going to do, got right to work, and coordinated everything seamlessly — including preparing for the crane operator’s arrival without any delays or issues. Their attention to detail and professionalism really stood out. It’s hard to find companies that deliver this level of service these days. I plan to use Oasis Heating and Cooling for all my future HVAC needs and will absolutely recommend them to my friends and neighbors. Call them today without hesitation!

Response from the owner:Thank you, Carlos! We truly appreciate your kind words and are glad to hear that you had an outstanding experience with our team. Your recommendation means a lot to us, and we look forward to assisting you with all your future HVAC needs!

Cheyenne Demott

We bought our house in January knowing our furnace and ac unit were old and needing replacing but hoping we could get a couple years out of it. Not the case, we called Oasis on Thursday, a technician was here Saturday morning and let us know we’d need them replaced sooner than we’d home Naim (maybe spelling that wrong) was super informative and answered all of our questions. Melissa got us schedule for Tuesday morning quickly! Today Fernando, Serge, and Joel showed up and installed everything and then cleaned up after themselves! They even made sure our requests about the placement of drainage pipes happened. I would absolutely suggest Oasis and their team if you need a new system or just repairs. Everyone we were in contact with or that came to our house was truly kind! Thank you Oasis!!

Response from the owner:Thank you, Cheyenne! We appreciate your kind words and are glad to hear that Naem, Melissa, Fernando, Serge, and Joel provided such great service. Your recommendation means a lot to us!
