Customer Reviews

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.

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.

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 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.

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.

Online booking was super easy and the technician was actually on time. He even taught me a couple of helpful tips while he was here. First time using Oasis and I would be willing to hire them again.

Response from the owner:Thank you, Mitchell! We're glad to hear that you found our online booking easy and that our technician provided helpful tips during your visit. We appreciate your willingness to hire us again and look forward to serving you in the future!

UPDATE REVIEW: Josh, the company manager, called, and we discussed the work done. I am receiving a new invoice with the correct tankless water heater information and labor warranty. I paid $7,000 for a new Navien tankless. It replaced my old Noritz tankless. I didn't have hot water for 5 days, so I felt compelled to get the work done (enter whining kids). Normally, I would ask a few more companies for estimates for this type of job. I feel he listened to me, but $7,000 is on the very high end, even though he said it wasn't. The 3/4 gas line was not replaced, and the condensation drains into my existing electric condenser. Alas, lesson learned: go without to get a reasonable price, and don't listen to whining kids about no hot water!! FIRST REVIEW: I'm still waiting for the owner to contact me about my tankless water heater installation.

Response from the owner:Thank you for your update, Susan. I appreciate you sharing your experience and I’m glad to hear that Josh was able to address your concerns regarding the invoice and installation. Your feedback about pricing and the installation details is valuable, and we will take it into consideration as we strive to improve. If you have any further questions or need additional assistance, feel free to reach out via text or call.

Mike responded quickly and luckily was nearby so came over pretty fast as well. He was off the clock but still came because I wouldn’t have heat on that cold winter night if my furnace didn’t get fixed. He also explained what went wrong and gave me some tips in case a similar situation occurs in the future. Was reasonably priced as he didn’t charge for the new fuse, overtime, etc. Will definitely use Oasis again for future HVAC needs! Oct 2026: Update - Oasis continues to be my HVAC company, they also do biannual HVAC maintenance for our mid-rise building, and is the company who provides services to all our residents. Naem is usually the person who comes for services and he’s very knowledgeable, helpful, and professional. Everyone who has been here were nothing short of polite and respectful. I will be using Oasis’ services indefinitely! Thank you to such a wonderful team!

Response from the owner:Thank you, Katrina, for your wonderful review! We're glad Mike was able to assist you quickly and provide valuable insights. Your support means a lot, and we look forward to helping you with your future HVAC needs!

They have replaced both my original AC and furnace over the years and kept them in tip top shape. Workers are always on time for maintenance and the few issues I had with pressure switches in my Rheem furnace. Highly recommend.

Fernando’s installation was very thorough and efficient. I had two hvacs replaced with new furnace and air conditioning. He went above and beyond to make sure all my zoned hvac system were calling properly since there were some issues with the dampers and control panel. Joseph came out a week later to top off the coolant since the AC wasn’t strong enough. Very professional and thorough. They are a top-notch team and would gladly use them again.

Response from the owner:Thank you, Jonathan, for your wonderful review! We're glad to hear that Fernando provided thorough and efficient installation and that Joseph followed up to ensure everything was working perfectly. We appreciate your support and look forward to serving you again!

Prompt and pleasant service. Highly recommend. 2026 Update: Just had my 20 tr old AC unit serviced by Joseph from Oasis. He was prompt and polite. He explained everything he was doing. Very happy with this company and strongly recommend them. My update for my fall service call is exactly the same as above except that he was able to come early and I was very happy to accommodate him! Excellent!

Response from the owner:Thank you so much for your business and feedback, Lucy! If any of your friends or family need help, please let them know about us!
