Desert Eye Associates had its beginnings in Tucson in 1979 providing medical and surgical eye care. The practice expanded to Green Valley and in 1997 we built a new clinic building. Hamstra Heating and Cooling installed the HVAC system at that time. Ever since then, they have provided prompt professional service. With a large office with many patients, we needed a company that knew our needs and responded quickly. To keep our system running worry-free, we take advantage of Hamstra’s preventive maintenance plan. Desert Eye Associates has been pleased to work with Hamstra Heating and Cooling for both our Tucson and Green Valley offices.
