We recently had the pleasure of working with Oasis and couldn't be more impressed with their service. From start to finish, they were professional, knowledgeable, and courteous. First of all, their customer service was exceptional. When I called to schedule an appointment, they were able to get us on the schedule quickly, and the technician's arrived right on time. They were friendly, respectful, and took the time to explain everything they were doing the job. The technician's were also incredibly knowledgeable about HVAC systems. They also were able to provide me with some helpful tips on how to maintain my system to prevent future issues. The pricing was on point and transparent, and there were no surprises when it came to the final bill. Overall, we are extremely satisfied with the service we received from Oasis and I would highly recommend them to anyone in need of air conditioning or HVAC services. They truly went above and beyond to ensure that I was a happy customer. Thank you so Chris, Stan, James, Keith and the whole Oasis crew for your excellent service!

A wonderful experience. Great communication by the team (James, Keith and Quincy). they were friendly, professional, clean and quality workmanship. Michael (owner) was reasonable with cost and able to complete work within specified time frame. I wish all companies had this level of professionalism and workmanship.

Can you say "Lifesaver" I can becuase Oasis came to my rescue when Champion heating & air company completely and UNPROFESSIONALLY dropped the ball day of installation. Oasis came in and picked up the ball and ran with it. They were able to replace my AC unit in no time and the guys worked really hard to get the job done right. Thank you Oasis and SHAME on you Champion.

My old air conditioning unit had faithfully served me for nearly 17 years but had become highly inefficient, resulting in soaring energy bills during the scorching summer months. Faced with the need for an upgrade, I decided to explore my options for a more efficient AC system. After reaching out to three different companies for estimates, I found that their prices exceeded my budget. During my search, I came across some positive reviews about "Oasis Heating & Air Conditioning." Upon contacting the owner, Stanley Hoenig, I was pleasantly surprised by his prompt and courteous response. Stanley promptly visited my home, thoroughly inspected my old system, and provided an estimate that was not only the most honest but also more budget-friendly than the other companies I had considered. Impressed by his professionalism, we quickly reached an agreement, and within 24 hours, he had sourced all the necessary parts, including the AC unit, furnace, and coil. The following morning, two technicians, Don and Quincy, arrived for the installation. Don, the lead technician, displayed extensive knowledge and experience, patiently addressing all my questions. Meanwhile, Quincy efficiently handled the installation of the furnace. In just one day, they completed the job to my utmost satisfaction. To top it off, Stanley, the owner, conducted a follow-up inspection later in the day, providing me with peace of mind. Oasis Heating & Air Conditioning may be a small company, but their commitment to delivering quality and affordability is undeniable. I wholeheartedly recommend this company to anyone seeking a top-notch HVAC system at the best price in town. I want to express my gratitude, especially to Stanley, who went above and beyond to secure the best deal for me. Excellent work, everyone!
