⭐⭐⭐⭐⭐
I contacted Oasis after reading their reviews online. Stanley promptly came out to give me a quote, answered all my questions (many before I even asked) and gave a very competitive price. The work was completed in a day by a courteous, thoughtful and quiet crew. My new HVAC system works beautifully and was installed just in time for these chilly mornings! I highly recommend Oasis for your heating and AC needs.
Warren Aston
⭐⭐⭐⭐⭐
We are very impressed with Oasis! We had multiple HVAC companies come to our home and Oasis was the only business the made us feel comfortable from day one. They were knowledgeable, friendly, helpful, and clearly not trying to get over on us. They cared about getting us the most efficient and safe system for our family and for our home. In the end, we're very happy that we chose to work with Oasis in replacing our 35 year old heating and air. We felt guided in the right direction with the equipment installed as we plan on converting the house to solar in the future and the pricing was the most competitive quote that we received. These guys, from the owners to the installers, are fantastic. Thank you, Oasis!

Honestly and without a doubt, this was one of the best experiences I have had in a long time with service, speed, proficiency and professionalism. I had an AC issue that needed quick repair, and they were able to squeeze me in the same day I called! Amazing! Chris arrived as scheduled, reviewed and assessed the issue, explained everything in detail with thoroughness and told me the plan for repair. He was fantastic. Guaranteed, we will definitely be using Oasis for all our future work. Highly recommend!
