San Antonio experiences 100-degree summer days and occasional sub-freezing winter nights, a 120-degree annual temperature range that stresses improperly sized heat pumps. Oversized systems short-cycle in mild weather, failing to dehumidify during spring and fall when humidity reaches 80 percent. Undersized heat pumps run continuously during July and August peak demand periods, driving electric bills up and shortening compressor life. Heat pump installers must account for the city's solar heat gain, typical insulation levels in older neighborhoods like Terrell Hills and Olmos Park, and duct leakage common in crawlspace installations.
San Antonio's Development Services Department enforces energy code requirements for heat pump system installation that affect equipment selection and duct sealing standards. Our heat pump service team stays current on permit requirements, inspection checklists, and CPS Energy rebate qualification criteria. We understand how local building practices, from pier and beam foundations to attic ductwork in ranch-style homes, affect system performance. This local expertise prevents the callbacks and failed inspections that occur when out-of-area contractors misunderstand San Antonio construction methods and climate demands.
