Hilo Weather and HVAC Load
NOAA's 1991-2020 climate normals put Hilo at 0 heating degree days and 3,283 cooling degree days per year. Cooling carries most of the load, which is why compressors and condenser fan motors wear out faster here than in northern cities. Freezing nights are rare here, but a normal year brings 2 days over 90°F.
| Heating degree days / year | 0 |

Hilo Housing Stock
Half the homes in Hilo were built before 1978 (Census ACS median), so the typical house is about 48 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Hilo has roughly 11,000 owner-occupied homes, or 65.5% of households. Homes here have a median value of $455,100 and households a median income of $78,713. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 1 hail day in Hawaii County. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. In Hilo, 22.7% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.
