Oasis personnel (Dave and Adrian) were fantastic. There is no other way to say it. They were professional in cleaning our air vents. They were on time, respectful of our belongings. They showed us before and after pictures of our air ducts. One thing I really appreciated they cleaned up after themselves leaving nothing for me to do later.read more

We went days without AC in Tucson when it was getting to the low 100s. I pulled the thermostat off the wall to check the connection, checked the breakers, checked the fuses, finally called a tech to come help...the door to the furnace just wasn't fully locked. He came and had it fixed within thirty seconds. I was so embarrassed, and I was waiting for him to be so condescending that the silly woman didn't know what she was doing (as most techs would in my experience), but he was so nice about it and didn't make me feel stupid at all. He also checked my coolant levels while he was there to make sure I got my money's worth for the service call fee. I am so appreciative for the great service, and my kids and I are sooo glad to have AC again (although I'm never admitting to them why it wasn't working 😂).read more

Oasis has been my "go to" for years, always professional and responsive. I bought my last HVAC from them at my last house. When the AC compressor went out on my current home, they were out same day working to get it running. Eventually I decided to replace the AC and they had a new unit installed 2 days later! Joe the lead tech discovered a problem with the damper motors not functioning correcting, which is what caused the compressor to burn out. So in addition to the new AC, they replaced the damper motors. Paul the owner personally followed-up to make sure everything was up and running and to my satisfaction. You can't go wrong choosing Oasis!read more

The entire crew at Oasis is top notch. When we installed a new AC last fall they showed up promptly and completed the job without a hitch. Additionally, Michael helped us install a gas line and worked diligently to make sure it was done properly. He promptly returned phone calls and was always cheerful and helpful. We are so pleased with the entire Oasis crew and want to give a special shout out to Javier and Enrique who went above and beyond our expectations. We believe Oasis is the best HVAC company in Green Valleyread more

Technician Darius came out to do a seasonal inspection on my A/C unit on May 3rd 2022. He was prompt, professional, friendly and went through each diagnostic step he conducted and explained what everything meant (although I probably only grasped about 5% of what his findings represented 😅). I have a two year old system and all in all it’s in great technical shape, but I wanted to establish myself with a company I could trust and must say I have found my future go-to HVAC professionals!read more

This Team from Oasis is the best!! This starts with the Customer Service Agent who initially responded to us, Brandi, to the gentleman who painted around the new thermostat at the finish of the project! They are all skilled Professional's, hard working, on time and friendly. We feel Trane A/C's are superior, and we are grateful to Oasis for installing our new unit.read more

David Lopez possesses the qualities a homeowner values in a customer service-oriented employee. He is: • On time. • Clear in his communications. • Answers all customer questions. • Follows up on the voiced concerns of customers to track down potential issues before they become tragic, cost-consuming problems. • Demonstrates he understands and respects his client base. He masks up to protect unknown vulnerabilities of clients because he is doing business in a community of homeowners who are all older adults, or they would not be eligible to live here. As a university nurse educator, I appreciate someone who enters many homes and does not need to be asked to take healthcare precautions which can only help Oasis clients. • Polite, cheerful, and shows appreciation for the customers he serves. David just earned Oasis a sizeable contract that someone without his qualities would not been able to pick up.read more

I had just moved into my new house on a Saturday, Sunday came and the thermostat was malfunctioning. Monday late in the day I called Oasis. They had someone out to my home Tuesday morning. They were awesome to deal with and very professional yet friendly. Seems the "smart" thermostat the contractor installed wasn't so smart..broken. They installed a new "non smart" thermostat in no time and my A/C was up and running like a champ. I decided to go with a contract with them, if they were that responsive to someone who never used them before I knew I would continue to get great service being a contracted customer. I highly recommend Oasis for sure.read more

JJ and Chris were absolutely great technicians- I was informed of what they were planning on doing, how they would do it, and of anything that I needed to do. They were extremely polite and conscientious, and asked me about anything that they thought that I would like to provide input on. They covered all of our furnishings near the work areas for protection and even parked their service vehicle on the street so as not to leave excessive tire marks on my driveway on a hot afternoon. They did a great job and their efforts are much appreciated. Thanks for having team members like JJ and Chris on your team.read more

Brandy kept us well informed and up to date about the difficulties in obtaining our Trane A/C unit due to manufacturing problems and offered various solutions and products to help solve the problem. We were impressed with Brandy from the start and she was always pleasant and available to answer our questions. Carlos and Noel installed our system. They were both very friendly and accommodating, answering all our questions and instructing us on the operation of our new system. They were very thorough during installation and did a great job cleaning up afterwards. We will definitely recommend Oasis Air Conditioning & Heating to anyone that asks!read more

My mini split unit I have on my storage unit failed. Oasis sent a technician within 2 days to trouble shoot and repair my unit. Unfortunately the system could not be economically repaired and I opted to replace it. I scheduled 3 companies for estimates and Oasis came in as my best option. Jerry (Sales) explained my choices and options. I felt he listened and accommodated my requests in a very professional manner. Jerry's bid was more than 10 percent below the others. Installation was done by Abraan and Chuck. Both technicians are very skilled, detail oriented and polite. The installation job they did for me is GREAT. It is what you expect from professionals. If I need another installation I would certainly ask for them by name. I would recommend Oasis Air-conditioning and Heating to anyone needing this type of work done. Matthew - Green Valleyread more

Oasis performed an excellent installation of my HVAC. They put a temporary AC unit in my bedroom window so I could endure the heat until my HVAC was installed.

The techs that installed the new ac ,Javier ,Isacc and Noel were without a doubt the best I have been associated with. I have built three homes and remodeled several others and have never encountered such pleasant, knowledgeable and efficient people. They were timely and had no problem with procedure. Teamwork was outstanding. I would recommend that crew to everyone! Brandy was also an intricate part of the process. She handled sale, scheduling and programming with a smile and made herself available for all of our needs. Oasis should be extremely proud of a crew such as this. Roger Bowtonread more

Everything about dealing with Oasis was first rate. Brandy was a pleasure to work with. She was very knowledgeable about her products. We signed the contract for one system and when she found out that it wouldn't be available she gave us an upgraded system for the same money. The installation team of Issac and Noel were top notch. They were neat, competent and very personable. Deal with Oasis-you won't regret it.read more

Great service from Oasis tech this morning! Jesus was as professional and courteous as all the techs have been since I started using Oasis for maintenance in 2017. He performed my semi-annual service with the usual skill and care I have come to expect from this local family owned business. Jesus even took the time to wipe down the duct registers to ensure a clean start for turning on my heater. My highest recommendation for this fair and trustworthy company.
