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.

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 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.

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.

Excellent service! We have them come out every spring to check up on our AC. Update: Still excellent service. I really appreciate the prompt communication and text updates. The service tech was very professional and helped fix a leak in our ac system.

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

This is a highly trusted business. I've worked with them for the past 10 years and they are absolutely, hands down one of the best customer focused businesses I've come across. I had an issue with my A/C recently (during one of those 90+ degree nights) and called to leave a message for the morning.......the owner of the business Mike Causevich answered my call and walked me thru what to do to fix my system without them having to come out. I give them my highest recommendation.

Response from the owner:Thank you, Sharon, for your kind words and continued trust over the past decade; we're glad Mike could assist you during that A/C issue, and we appreciate your highest recommendation!

Jacqueline Davila Benson

Knowledgeable, friendly and on time. Would definitely recommend.

Ben Matsche

Danny is a legend. Fixed a problem multiple other AC companies either couldn’t diagnose or couldn’t fix. Great tech and guy.

Response from the owner:Thanks, Ryan! We appreciate your kind words about Danny and are glad he could help resolve your issue. Your feedback means a lot to us!

Janis Sayer

They really did a great job. The repair people were very nice, communicative, and went above and beyond to help me understand the problem.

Response from the owner:Thank you, Janis! We're glad to hear that Danny provided excellent service and clear explanations. Your recommendation means a lot to us!

Rina Patel

(July ‘26) Reached out as my AC went out. Was ghosted by Craig. Understand it was a holiday weekend. But no followup even the next week. Very disappointing. (January ‘26) The nicest man came out at 7am to check out my system. And then another super nice person came out at 12:30pm, part in hand to fix my system, saving me from having to replace my furnace. Both people were kind, professional, and worked quickly. I’ll be using them again, for sure!

Response from the owner:Thank you, Rina! We appreciate your kind words about our team and are glad we could assist you promptly. We're looking forward to helping you again in the future!

Oasis was responsive to our call and had Damir out to see us within two hours. He arrived with booties for his shoes (always appreciated!) and was able to diagnose and solve our AC issue quickly.
