Customer Reviews

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.

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 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 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 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 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.

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.

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.

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!

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!

Service is always top-notch, on time, knowledgeable, and open to questions when needed. I enjoy having Naem come.

It is easy to see that he enjoys his work and is a great representative for Oasis both professionally and personally.
