Meet Eric Chang of O3 in Richardson

Today we’d like to introduce you to Eric Chang.

Eric, can you briefly walk us through your story – how you started and how you got to where you are today.
Edward, my partner at O3, and I started flipping houses back in 2011. Many of the houses we bought had the same characteristic: reeks from pets or other odor. At the time, we tried to find companies or services which can get rid of the smell, but we always came short. Under time pressure, we had to device our way of getting rid of the odor. From experimenting with different techniques and equipment, we discovered ozone worked the best in getting rid of strong permanent odor.

Finally, this past year, Edward and I decided we should tap into this niche market and start our own company to provide service to help people in improving the smell of their homes, especially with odor from pets, tobacco, and other sources. What we are finding when we started is people are curious on how the service works since there is nothing really like the O3 odor elimination service for residential properties in north Texas.

Everyone we spoke with had same reaction of “wow, didn’t realize this service is available”. As we continue to educate people, business has picked up drastically. We are on track to end our first year with a bang.

Great, so let’s dig a little deeper into the story – has it been an easy path overall and if not, what were the challenges you’ve had to overcome?
We have to educate many of customers or potential customers. One, people does not realize there is a way to permanently remove odor for their homes. Many people utilize freshener or for flippers, new floor and paint to cover the odor. Education is where we have to spend our time on in order for O3 to be successful.

Alright – so let’s talk business. Tell us about O3 – what should we know?
O3 provides service to improve the smell of residential and commercial properties. We utilize the latest Ozone technologies to destroy odor molecules and give our customers a fresh “after the rain” smell after each treatment. Unlike other home fragrance which only masks the odor or smell, our odor treatment destroys odor at the molecular level, so it gets removed permanently and safely. We guarantee 100% result satisfaction or money back. All our technicians are certified and trained with the National Ozone Association.

Is there a characteristic or quality that you feel is essential to success?
Persistent on your vision and hard work.
