FAQ’s
Report
Despite popular belief, the square footage per ton "rule-of-thumb" is a horribly inaccurate method of sizing comfort equipment. The only way to determine the correct system sizing for your home is to calculate the heat gain/loss in BTUs using ACCA Manual J or ASHRAE load calculations.
If you consider two different buildings (each 2,000 square feet) - one built in the 1960's with poor construction quality and the other built to modern code requirements - the square footage per ton method would assume that both homes require the same size system.This is absolutely not the case!

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.
