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.

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.

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 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.

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.

Damir is professional, calm, and provided useful information after he conducted my yearly furnace check-up. He and others from Oasis installed the unit 8 years ago. I appreciate the continuity and his vast experience.

Great service! They came out quickly to replace my water heater and Steve and Amer went out of their way to fix a badly placed shutoff valve in a tight closet. I use Oasis for my HVAC too because they are willing to service the rooftop a/c.

Furnace service: Mark was great- friendly and efficient. Called before my appointment window and gave me the specific time he would arrive, which I appreciated. AC service: Joseph was very friendly and efficient. He kept me updated on the work he was doing. I’ve used Oasis for years and am always impressed with their professionalism. Very reasonable prices on the HVAC services. Prior review:The work was done quickly and plumber was nice but quite expensive for a short job so I’ll go back to my previous plumber

Response from the owner:Thank you, Susan, for your feedback! We're glad to hear the work was done quickly and that you found the plumber nice, and we appreciate your honesty about the cost. We hope to still work with you for all your HVAC needs!

The OASIS team was fabulous in resolving our emergency and quickly installing a needed new compressor. The compressor was damaged when other workmen were working on a separate system at our house. We were imminently leaving the country. We urgently called Oasis. Mike quickly identified a new unit, ordered it and had it installed the next day. The installation team including Michael and others were so easy to work with and did a great job. THANK YOU, OASIS! Now we can leave the country for our trip with peace of mind! We will always trust you with our system needs! And when we needed them again this week, they were out immediately and addressed out needs. Thank you, Oasis! Much appreciated.

Response from the owner:Thank you, Jane! We're so glad to hear that our team was able to quickly resolve your emergency and get you ready for your trip. It's great to know that Mike, Michael, and the installation team provided you with excellent service. We appreciate your trust in us for your system needs!

Great service, friendly, easy to schedule. Found a blockage in our chimney that we never would have noticed and could have been a major health concern if not addressed. Thanks!

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.

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.

Katrina Ta

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.

Response from the owner:Thank you, Ted! We appreciate your trust in us for your AC and furnace needs and are glad to hear about your positive experiences with our team. Your recommendation means a lot to us!

Joseph was great. On time. Super nice. Serviced everything as asked!

Response from the owner:Thank you, Mjm! We're glad to hear that Joseph provided great service and met your expectations. We appreciate your feedback!

Jonathan

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!
