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.

Emily H.

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 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 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.

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.

I have had outstanding service from all technicians who have been to my home.

He explained everything so well, and was able to arrange for a furnace to be installed within a few days. Vaha and Anel and their crew came to install both an air conditioner and furnace. They were on time, professional and got the entire job finished in less than 4 hours. Highly recommend Oasis plumbing, heating and cooling -

Joseph from Oasis Heating did a fantastic job servicing my furnace for the winter. He was incredibly thorough and took the time to explain everything clearly so I understood what was being done.

Our heating wasn’t working and Oasis was able to come over early the next day to fix it. It was a loose wire and a quick fix, so I’m grateful we didn’t have to wait days for an appointment like with other places we’ve contacted before. I really appreciate the friendliness of everyone on the Oasis team and the ease of communication! Thank you and will be calling you guys when needed :)

Autumn Riggenbach

Such a great experience! Learned about them through referrals in Lakeview. We closed on our apt on Tuesday. I was able to have someone come out on a Wednesday to check out the furnace and dehumidifier. The team was able to replace everything by Friday.

I was nervous about up charges with the cold weather just kicking off, but instead, Oasis gave me a discount and helped bring everything up to code (for free or extremely low costs).

Highly recommend! I will be purchasing their 2x a year services too. The guys were such gentlemen, on time and super clean.

Thank you!!

Response from the owner:Thank you, Autumn! We appreciate your kind words and are glad to hear you had a great experience with our team. We look forward to serving you again with your biannual services!

Oasis is an outstanding HVAC contractor. We've used them for over tenyears and they always offer quick, reliable service. We're on their monthly maintenance program for the two systems in our two-flat, and it's a great value. In addition, they recently replaced our furnace and thermostat with an updated model. The work was done at a reasonable price and very quickly, finished in about 3.5 hours. I highly recommend Oasis!

Our second time using Oasis and I could not be happier. GREAT service and reasonably priced. The technician, Joseph, was professional, friendly and very knowledgeable.
