About Us

Oasis Heating & Air Conditioning originated in mid-2019 by then 28-year old Erik Peterson with a vision to own and operate a heating and cooling company that ACTUALLY cares about its customers.

A company that does not use the traditional sale “tactics” that all the other companies use. We believe in full and complete honesty because nobody likes to be deceived and taken advantage of. That’s why we hold quality, customer service, and overall satisfaction in the absolute highest regard.

Oasis Heating & Air - Built Upon Honesty and Quality

We have the ideal that being honest, giving the finest product, and being absolutely sure that we did everything we possibly can to make our customer 100% satisfied, will not only churn into loyal and consistent clients, it’s just the right thing to do. That method has not only proven to be very effective; it has given us the opportunity to make our community a happier, more comfortable, and better place to live.

At the end of the day, to us, it's not only about providing the absolute finest quality, service, and pricing, it’s about receiving that feeling of true gratification from our customers after the job is complete. Seeing those smiles of true satisfaction, and that feeling that we not only did our job, but also helped someone in need of our service, is why we will never stray from our base ideology – Honesty & Quality!
