Heating & cooling in Salt Lake City: what the local homes tell you
The median home in Salt Lake City was built in 1965, older than Utah as a whole, where the median is 1992. 65% of homes were built before 1980, and 45% before 1960. 46% are owner-occupied, and 43% are single-family detached houses.
Salt Lake City is in Salt Lake County, which the 2021 IECC puts in climate zone 5B, the cold-dry zone most of Utah shares. RESNET's county table lists a 1% cooling design temperature of 96°F and a 99% heating design temperature of 11°F for Salt Lake County. Those are the figures a load calculation sizes equipment against — not the record high or low, but the temperature the system has to keep up with on a normal hard day.
72% of occupied homes in Salt Lake City heat with utility gas and 24% with electricity (statewide it is 79% and 17%).
Salt Lake City sits at about 4,200 feet. The National Fuel Gas Code says a gas appliance's input rating only holds up to 2,000 feet; above that it is reduced — by 4% for every 1,000 feet above sea level, roughly 17% here, unless the manufacturer's instructions or the local inspector say otherwise. Ask whether the furnace is set up for this elevation.
In older homes the ductwork was often sized for the equipment that came with the house. When a system is replaced, ask for a load calculation rather than a like-for-like swap: the house may have new windows, insulation or additions the old sizing never saw.
