Heating & cooling in Millville: what the local homes tell you
The median home in Millville was built in 1981, older than Utah as a whole, where the median is 1992. 49% of homes were built before 1980, and 16% before 1960. 93% are owner-occupied, and 94% are single-family detached houses.
Millville is in Cache 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 93°F and a 99% heating design temperature of 0°F for Cache 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.
94% of occupied homes in Millville heat with utility gas and 6% with electricity (statewide it is 79% and 17%).
Millville sits at about 4,600 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 19% 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.
