Very pleased with professionalism, quality and price. James, Keith and Quincy completed Al elements of heat and air new installation on time and to specifications. They communicated with us well about every step of the process. It was nice to have someone come into the home and just complete the work without any issues. Owner Michael was very clear without sales hype. Strong background and understanding of home needs.

Michael, James, Keith were all GREAT! I received about 5 estimates for replacing an original 32 year old split level Rheem system. Oasis was neither the least expensive but certainly not the most expensive. They have only been in business a short while but I took a chance with them and they delivered! Prompt, flexible pricing, clean work, friendly. A complete system including duct work and I hardly even knew they were here working. I whole heartedly recommend these guys! (And I do not write reviews!)

My air conditioner stopped working last weekend. I called a couple of places and was not able to get anybody to come out in a reasonable time. I came across an oasis and they were very helpful and had a tech out later that afternoon. The tech was very knowledgeable and the Price was fair. They had our ac back up in running in no time. I hope I do not need any repairs again soon, but if I do Oasis will be my first call.
