Customer Reviews

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 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 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 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.

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.

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.

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!

We had been without AC for 8 days, through a heat wave, by time Chris (plumber) was able to come clear our drain line. Two other companies had essentially told us they couldn’t help and/or had given us crazy timelines for helping us. Chris was so nice to work with and we are SO GRATEFUL for his help.

AWESOME, AWESOME, AWESOME! I can't say enough wonderful things about Oasis! Our AC broke... I contacted 7 different companies, and they never got back to me.

Mark Saran

Truer calling to schedule service, was picked up by an answering service 5 separate times and had to give the same information, answering service had to no records of previous call. Also tried texting them and was told, “I'll pass your message along and have someone get back to you as soon as possible.” Never received a reply. It should not be this difficult to give a company my business.

Immanuel Choe (Manny)

They were quick to arrive and I had my AC capacitor replaced within a couple of hours after it failed. Only the cost of the service which was $440 was on the higher end in my opinion but I would definitely seek their services again.

Benjamin Rivard

I called Oasis to come out as one of the AC units on the roof of our house makes very loud rumbling vibrations when it runs. I am so glad that I called Oasis; from the moment he arrived the technician, Hani, was incredibly professional and knowledgeable, and was able to figure out that the builder had installed the unit in such a way that the vibrations transfer into the roof structure, and that the unit itself was working normally. Hani was very up front about options we have to remedy this issue, and suggested that we start with changing out the plastic pad it is on and installing vibration isolating rubber padding for the unit to sit on. He did discuss several other "fixes" that we could consider if the padding doesn't work, but was confident it would help. Hopefully we can get the service scheduled soon and get it taken care of, so I can't rate/speak to the end-result yet, but my experience with Oasis so far has been phenomenal.

Oasis management team- Hani deserves recognition for representing your company extremely well. His attitude and professionalism made me want to continue working with your company going forward. If we get the vibration issues sorted out, I see no reason why I would ever call another HVAC company for our maintenance and emergency needs.

Response from the owner:Thank you, Benjamin, for your fantastic review! We're glad to hear Hani provided you with such professional service and clear options for your AC issue. We appreciate your trust in us and look forward to helping you resolve the vibrations soon! We are here for all of your HVAC and Plumbing Needs!

Romy Connor

I used Oasis for both a/c maintenance and a water heater flushing. Guys were on time and very professional! Fair quote on both services..and didn't try to upsell me on things others had tried to do-luckily I have a friend that's a plumber and said what was needed. Will definitely be calling Oasis for future plumbing needs!
Appreciate the honesty. One other company gave me a ridiculous quote..for something I didn't need-won't mention any names-but all reviews mentioned how high their pricing was-do some research!

Response from the owner:Thank you, Romy, for your kind words and for trusting Oasis with your a/c maintenance and water heater flushing; we appreciate your feedback and look forward to assisting you with any future plumbing needs! We are here for all of your HVAC and Plumbing Needs!

Ann Wilson

Naem was fantastic. He was friendly, on time, and communicative about our furnace. The service fee was very reasonable, and I never felt as though he was trying to upsell me on any Oasis programs.

Response from the owner:Naem will love to read the kind words you left about his service! Thank you for the feedback and we hope you visit us again!

Chris Knoff

Fast, high quality, helpful, professional.

Response from the owner:Thank you, Chris, for your kind words; we're glad to hear you found our service fast and professional, and we appreciate your feedback! We are here for all of your HVAC and Plumbing Needs!

Patrick Hoffmann

Our furnace failed on one of the coldest days this past winter, and Mike from Oasis Heating & Cooling responded immediately. He came by quickly, assessed the situation, and helped us arrange a full furnace replacement without delay. The installation team—Damir and his son—were excellent: efficient, professional, and respectful of our home. They completed the work within a few hours, and the new system has worked flawlessly ever since. From start to finish, the experience was smooth, honest, and reassuring. Mike and his team clearly care about quality and customer service—no upselling, just straightforward help when you need it most. I highly recommend Oasis for any HVAC service, repair, or replacement. Five stars, no question!

Response from the owner:Thank you, Patrick, for your wonderful review! We're glad Mike, Damir, and his son could provide you with efficient service and a smooth experience during such a challenging time. Your recommendation means a lot to us! We are here for all of your HVAC and Plumbing Needs!

Roxanne Corkin

Honest, efficient, friendly, reasonable fees. I cannot recommend highly enough.

Response from the owner:Thank you, Roxanne, for your kind words and support; we truly appreciate your recommendation and are glad you had a positive experience with us! We are here for all of your HVAC and Plumbing Needs!

Layne Turci

Had an EXCELLENT experience with Oasis plumbing. My AC went out right before this big heat wave. Every other tech I had out told me I would have to replace the whole thing, and they couldn't do anything for me until after the slate of 95+ degree days we had coming up. Some told me that it would cost thousands to fix my current problem. Oasis came out and 10 minutes later, my tech Damir tells me he's fixed my AC by replacing a part -- he carries a spare in his bag. So he's patched it for the summer -- a $300 solution when I was prepared to spend $8,000+. He also walked me through what was wrong with the system, what would need to be replaced eventually, and how to keep the ac going through the rest of the summer. I felt his price was very reasonable (he even took a little bit off because he misspoke when he told me the original price) and he was able to truly help me, not try to get more money out of me. The entire team at Oasis was very kind and accommodating -- they called me to offer me an earlier appointment slot and did their best to get me on the schedule on short notice.

Response from the owner:Thank you, Layne, for sharing your excellent experience with us! We're glad Damir could provide a quick and affordable solution for your AC, and we appreciate your kind words about our team's efforts to accommodate you on short notice. Your satisfaction is our priority! We are here for all of your HVAC and Plumbing Needs!

Danny was incredibly helpful during his visit. He quickly identified our issue and helped resolve it during his visit. He was able to explain clearly how we can manage our unit moving forward.
