Ductless HVAC Services from Oasis Plumbing, Heating & Cooling

The installation of a ductless mini- or multi-split system avoids tearing down walls, disruption, and mess. Little more is required beyond a three-inch hole in an exterior wall. An outdoor compressor (operating so quietly, you won’t be certain it’s running) links to lightweight, streamlined air handlers mounted up high on the wall or cassettes set into the ceiling. Surprisingly powerful and wonderfully energy efficient, the ductless system delivers heating and cooling wherever you want or need it.

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.

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.

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.

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.

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.

I used Oasis for HVAC installation and was very happy with the experience. They have fair pricing, are responsive, and you deal with real people that are knowledgeable. One year later I’m using them for maintenance which I feel is important. They are supportive with good communication. I would highly recommend them.

Response from the owner:Thank you, Bonnie! We're so glad to hear you had a great experience with our team and appreciate your recommendation. Your satisfaction means a lot to us! We're here for all of your HVAC and Plumbing needs!

Terry Kiely

I have been a happy client of Oasis for a number of years now and today’s visit from Naim was one of the best. Our AC went out on Saturday night, I posted a service request at about 8pm and Naim arrived Sunday right on time at 11:30am. He quickly diagnosed the problem and showed me the blown capacitor. Not only did Naim repair the unit quickly and cleanly, he also explained why it happened and gave me some pointers on how to improve the energy efficiency of my AC usage. Would definitely recommend and use again. Had Joseph out here today(7/14/26) for ac service…another great experience with oasis

Response from the owner:Thank you, Terry! We appreciate your loyalty and are glad to hear about your positive experience with Naim. It's great that he provided thorough explanations and tips for your AC. We're also pleased that Joseph met your expectations. Your recommendation means a lot to us!

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!

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!

Joseph came out. Very quick, polite professional. Made sure I understood the maintenance and charges.

Response from the owner:Thank you, Kevin! We're glad to hear that Joseph provided you with quick and professional service while ensuring you understood everything. We appreciate your feedback!

Patrick Schulze

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!

Sharon OBrien

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!

Response from the owner:Thank you, Ben! We're glad you experienced friendly and professional service. It's great to hear that our technician was able to promptly address the AC issue and provide clear information. We appreciate your feedback!

Ryan Raccuia

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!
