Customers note responsive scheduling, careful troubleshooting, and systems restored quickly. Reviews frequently mention courteous technicians, fair pricing, and clean work.

Furnace stopped working.
Called in the AM they sent someone (Eric) over in the PM,
I was expecting he'd look at the furnace, say something needs to be replaced, we have to order it and it will take a few days,
Instead he opened it up and fixed it.
I was impressed.
Something breaks again they'll be my first call.

Erik from Oasis Heating and Air went above and beyond when I needed help outside of regular business hours. He was at my house within half an hour of my call and had my older system up and running in no time. He was honest, courteous, and clearly skilled at what he does. I truly appreciate his responsiveness and would recommend him to anyone in need of HVAC help.

Eric was quick and professional. He tuned up two furnances and changed thier filters. He talked about life expectancy and common problems, answered all my questions

Oasis Heating & Air Conditioning is hands down the best HVAC company I’ve ever worked with. Erik is honest, professional, and incredibly knowledgeable — he treats every job like it’s for family. He doesn’t cut corners, shows up on time, and genuinely cares about doing things right. If you want quality work and someone who actually gives a damn about their customers, call Oasis. I wouldn’t trust anyone else with my heating or cooling needs!

Erik with Oasis heating LLC is a very professional and efficient installer. Anyone can provide a service, but it is a welcome, uncommon experience to have a superior service provider! I believe that any other business Eric would be a part of he will provide the same superior service.
It was a pleasure working with him. While it is never a pleasure to spend money on something like this, Eric relieved the pressure by his kind and efficient work ethic.
He has vowed to return to fine-tune any request regarding my new system. I will refer and I would recommend him to any of my friends or anyone who would ask. Thank you Erik
