When considering installing a new or replacing an existing A/C system, capacity of the system, and the energy efficiency of the system are the two essential items to be considered. Each building is unique, requiring different solutions, and one of Stan’s experienced ‘Whole House’ Experts will be glad to help you determine which system meets your needs. A/C systems that are too small will be unable to keep your building at the ideal temperature. But a system that is too large will cost more to purchase and operate, and will be less comfortable than a properly sized system.
Stan’s will help you determine the capacity of your A/C system, but we first must know what your comfort goals are. The industry standard for determining the capacity needed for the Central Texas climate is to maintain an inside temperature of 75 degrees, when the outside temperature is 100 degrees. Your particular preference may vary. Units do this by removing the necessary amount of heat (BTUs) from your building’s air. A/C units range in capacity, from 1.5 ton systems, which can remove about 18,000 BTUs per hour, to 5 ton systems, equipped to remove about 60,000 BTUs per hour.
