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.

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.

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.

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 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.

This is my third experience having Oasis help with our HVAC and they continue to deliver great results. Michael and Joseph went above and beyond to work on our system. The were super knowledgeable and helpful, and great at communicating and troubleshooting to get our system and keep it in tip-top shape! We also signed up for their annual maintenance program and that will continue to keep our HVAC running smoothly.

I’ve used Oasis for years and they are very timely and professional

Curtis Malasky

Hi bought a high efficiency furnace from Oasis in 2021. Since then I've had one service call that went great. Today I can home from a trip to find a house without heat. It was snowstorm season, and the crew were very busy, but in lieu of a service call, they were able to walk me through a very easy solution which worked great. They've always been very prompt and skilled. *****

Mark Humphries

Rolled with the punches. They were able to replace my water heater that was practically blocked in by my furnace, and kept me well informed along the way as new obstacles popped up. Much appreciation for they're plumber and the HVAC guy for getting it done and putting out some fires along the way

Melissa W

Simply the best. These guys have been helping me for years. They are not only excellent at what they do, they are totally trustworthy. I would not hesitate to hire them. They do my biannual servicing and help when I have issues which has been fairly often. Can’t recommend them highly enough!

Jason Benacka

We called Oasis on a Saturday when our furnace went out and they were able to come out within 2 hours. Joseph was great, quickly assessed our problem and explained the repairs. He was thorough and got our heat back up and running

miguel ortiz

Very quick and about 5000 cheaper than the first estimate. Fernando was good

Natalie Z

Doug Brown

Joseph came out and provided good info and troubleshooting. Good service

Kristin Schrepferman

Thank you to Danny! He was friendly, prompt, knowledgeable and professional. He patiently troubleshot my radiant heat issue, fixed it, and followed up to make sure everything was working properly as the system heated up over several hours. Oasis will be my first call for any future plumbing, heating or cooling needs. The office was also great—easy to reach, quick responses, and simple scheduling. Excellent service at a fair price.

Response from the owner:Thank you, Kristin, for your 5-star rating! We appreciate your support.

Asja Dizdarevic

Top tier service! My son has been experiencing a lot of allergies lately and we decided to reach out to Oasis Heating and Cooling to do an air vent cleaning. Having vents cleaned for a 6 bedroom and 5 bath house is not going to be cheap so we were not shocked that it was costly: it’s not just a quick job, it’s an all day job that requires 4 employees to come out, carry a massive machine in the house, close off all the vents and then do whatever they do to clean the actual vents. The team arrived at 7 am- we were a household that doesn’t wear shoes but they came ready with shoe covers which was really nice because I didn’t prepare any for them. They got straight to work- they were very professional but also very patient and kind to my children who had 1000 questions for them and even challenged them to squats and pushups. The team worked diligently from one room to another and cleaning up after themselves. They took a break for lunch and then came back to finish the job. I was just impressed how they took care of the equipment but were also respectful of our home and made sure to clean up after themselves- triple checking that they put things back and cleaned up. We are very satisfied with their service and work ethic- we highly recommend them.

Two years ago there was a major snow storm on Christmas eve. It was so cold outside (-22 degrees) that the condensation rising from the pipe froze our vent exhaust pipe and caused our attic furnace to shut down. We called Oasis heating and cooling because we have two small children, one that was a baby at the time and the team was at our doorstep the next morning at 6 am to fix it. I could cry right now writing this because our house was freezing and they had a hundred calls coming in that day but because they knew we have small children, came out immediately. You never forget companies like that and their commitment to service, professionalism and kindness. Thank you Oasis Heating and Cooling for everything!

Liqa Hakimi

I had an excellent experience with Oasis Heating & Cooling. Their service was fast, professional, and very reliable.

I’m really happy with their work and definitely recommend Oasis Heating & Cooling to anyone who needs honest and quality service! 💯🔥

Maddy Scaletta

The customer service at Oasis is top tier! The office assistant, Chris was pleasant in answering my questions and directing me in the right direction!

John Mickelson

Joseph came, explained everything I could've needed to know, showed me pictures of the clog, cleaned it out, couldn't have been easier. This is the furnace they installed 10 years ago, we haven't had any issues in 10 years, and this would have been prevented of we got regular services! Happy to support this local company and they do great work.

I will never call another service. Everything about Oasis is 5 stars. When I called them just to get information about their services and schedule an appointment, the customer service representative was informative and courteous. I also delightfully surprised that they could schedule a 7 AM appointment so I didn’t have to miss any work. On the day of my appointment, Joseph arrived at 7 exactly! He was also courteous, informative, and efficient. He sealed the deal on me being a lifetime customer of Oasis. I highly recommend everyone give this outfit a lot of consideration when deciding who to call. You won’t regret it.

Sidney Stewart

I can’t say enough good things about Oasis Plumbing, Heating & Cooling. They came out on a Saturday in terrible weather when every other company either wasn’t answering or was quoting outrageous weekend rates. My Nest thermostat wiring and furnace configuration needed attention, and they handled it quickly and professionally.

Naem, the technician, was on time, knowledgeable, and incredibly kind throughout the entire visit. He explained everything clearly and made sure the system was functioning perfectly before he left. The gentleman who answered the phone was just as impressive — respectful, accommodating, and genuinely helpful when I called in desperate need of assistance.

Thank you so much for coming through when it mattered most. You truly saved the day for me. Highly recommend! 👏🔥
