Our second time working with QET
We got an EPS unit last March and it has greatly improved the air quality in our home. When it came time to refill the liquid, we had to call the company again to help us put it in since the unit was in an awkward place. Daniel the technician arrived on time and patiently explained how to access the unit and refill it ourselves so we wouldn't have to call each time. He was very helpful and knowledgeable. Very happy to work with this company!
